Skin cancer linked to other cancer risks, Study finds


 By Karen Rowan
People who have had common skin cancers may be at an increased risk of getting cancer again in their life, according to a new study.
The study found that women with nonmelanoma skin cancers (such as basal cell carcinoma or squamous cell carcinoma) were 26 percent more likely to later develop another form of cancer, compared with women who didn't have these skin cancers. In men, the risk increased by 15 percent, the study found.
The study included more than 150,000 people who were followed for more than 20 years, so the findings strongly add to the growing evidence of a link between skin cancer and later development of other cancers, said Anthony Alberg, a professor of epidemiology at the Medical University of South Carolina.
The increased risk of cancer seen in the study isn't high enough to warrant recommending that people with nonmelanoma skin cancers undergo cancer screening tests earlier or more often than generally recommended, said Alberg, who was not involved in the new study. It does, however, raise the question of whether more screening might be beneficial for this group, and future studies might look at this, he said.
Nonmelanoma skin cancers are "so common we can't even count them," so the findings have public health significance, Alberg said. A 2006 study showed there were 2.1 million cases of non-melanoma skin cancer in the U.S.
The link may also help researchers to better understand cancer biology, he said.
The new study is published today (April 23) in the journal PLOS Medicine.
How cancer risk increases
For the study, researchers led by Jiali Han, an associate professor of dermatology at Harvard Medical School, looked at cancers among people participating in two large studies — the Health Professionals Study, which began in 1986, and the Nurses' Health Study, which began in 1984. By 2008, about 29,500 cases of cancer had been diagnosedin the 153,600 people in these studies.
Results showed that people with nonmelanoma skin cancer were at an increased risk of developing the deadly skin cancer melanoma, and that women with nonmelanoma skin cancer were at increased risk of lung cancer and breast cancer, according to the study. The researchers accounted for factors that could affect the results, such as people's ages, smoking, and for women, the use of hormone replacement therapy.
Alberg said that previous studies have linked common skin cancers with an increased risk of other types of cancers. In the new study, there was increased risk of other types of cancer as well, but these increases did not rise to the level of statistical significance. Still, the fact that 23 out of 28 cancer sites examined were trending toward an increased risk means there is likely something underlying the links, he said.
"The increase really doesn't map well with any specific cancer… there's more of a general increase in cancer risk," he said.
Why the link?
The link between nonmelanoma skin cancers and developing melanoma later may be due to sun exposure, the researchers said.
But the reason for the general increased risk of other cancers is unclear. Some researchers suspect that the cellular machinery involved in DNA repair may not work as well in some people, leaving them at an increased risk for any type of cancer, Alberg said.
By studying people who have developed more than one type of cancer, a situation called "multiple primary cancers," researchers can develop a better understanding of cancer biology, he said. The skin cancers in the study are common, and unlike other primary cancers, they are not typically treated with radiation or chemotherapy, both of which have been linked to increased cancer risk later on.

Study says nut eaters have lower cancer, heart disease risk

Help yourself to some nuts this holiday season: Regular nut eaters were less likely to die of cancer or heart disease — in fact, were less likely to die of any cause — during a 30-year Harvard study.
Nuts have long been called heart-healthy, and the study is the largest ever done on whether eating them affects mortality.
Researchers tracked 119,000 men and women and found that those who ate nuts roughly every day were 20 percent less likely to die during the study period than those who never ate nuts. Eating nuts less often also appeared to lower the death risk, in direct proportion to consumption.
The risk of dying of heart disease dropped 29 percent and the risk of dying of cancer fell 11 percent among those who had nuts seven or more times a week compared with people who never ate them.
The benefits were seen from peanuts as well as from pistachios, almonds, walnuts and other tree nuts. The researchers did not look at how the nuts were prepared — oiled or salted, raw or roasted.
A bonus: Nut eaters stayed slimmer.
"There's a general perception that if you eat more nuts you're going to get fat. Our results show the opposite," said Dr. Ying Bao of Harvard-affiliated Brigham and Women's Hospital in Boston.
She led the study, published in Thursday's New England Journal of Medicine. The National Institutes of Health and the International Tree Nut Council Nutrition Research & Education Foundation sponsored the study, but the nut group had no role in designing it or reporting the results.
Researchers don't know why nuts may boost health. It could be that their unsaturated fatty acids, minerals and other nutrients lower cholesterol and inflammation and reduce other problems, as earlier studies seemed to show.
Observational studies like this one can't prove cause and effect, only suggest a connection. Research on diets is especially tough, because it can be difficult to single out the effects of any one food.
People who eat more nuts may eat them on salads, for example, and some of the benefit may come from the leafy greens, said Dr. Robert Eckel, a University of Colorado cardiologist and former president of the American Heart Association.
Dr. Ralph Sacco, a University of Miami neurologist who also is a former heart association president, agreed.
"Sometimes when you eat nuts you eat less of something else like potato chips," so the benefit may come from avoiding an unhealthy food, Sacco said.
The Harvard group has long been known for solid science on diets. Its findings build on a major study earlier this year — a rigorous experiment that found a Mediterranean-style diet supplemented with nuts cuts the chance of heart-related problems, especially strokes, in older people at high risk of them.
Many previous studies tie nut consumption to lower risks of heart disease, diabetes, colon cancer and other maladies.
In 2003, the Food and Drug Administration said a fistful of nuts a day as part of a low-fat diet may reduce the risk of heart disease. The heart association recommends four servings of unsalted, unoiled nuts a week and warns against eating too many, since they are dense in calories.
The new research combines two studies that started in the 1980s on 76,464 female nurses and 42,498 male health professionals. They filled out surveys on food and lifestyle habits every two to four years, including how often they ate a serving (1 ounce) of nuts.
Study participants who often ate nuts were healthier — they weighed less, exercised more and were less likely to smoke, among other things. After taking these and other things into account, researchers still saw a strong benefit from nuts.
Compared with people who never ate nuts, those who had them less than once a week reduced their risk of death 7 percent; once a week, 11 percent; two to four times a week, 13 percent; and seven or more times a week, 20 percent.
"I'm very confident" the observations reflect a true benefit, Bao said. "We did so many analyses, very sophisticated ones," to eliminate other possible explanations.
For example, they did separate analyses on smokers and non-smokers, heavy and light exercisers, and people with and without diabetes, and saw a consistent benefit from nuts.
At a heart association conference in Dallas this week, Penny Kris-Etherton, a Pennsylvania State University nutrition scientist, reviewed previous studies on this topic.
"We're seeing benefits of nut consumption on cardiovascular disease as well as body weight and diabetes," said Kris-Etherton, who has consulted for nut makers and also served on many scientific panels on dietary guidelines.
"We don't know exactly what it is" about nuts that boosts health or which ones are best, she said. "I tell people to eat mixed nuts."

End Stage Cancer Patients

image
How they are participating
We are going to run a Fund A Need campaign for Giving Tuesday. Lazarex Cancer Foundation helps end stage cancer patients participate in FDA clinical trials (often their last and only hope to beat the cancer). One of the ways we help is by reimbursing patients the out of pocket expenses for associated costs like airfare, hotel, rental car, gas, tolls, a travel companion, etc. So the Fund a Need will allow donors to contribute to selected needs and they can choose the donation level that works for them. For example: Airfare to a clinical trial for a year is $5,000 and we’ll break it up into 50 giving segments of $100. A rental car for a year is $800 with 32 giving segments of $25 and so on.

Womb cancer risks decrease with exercise, diet and coffee

  Written by Marie Ellis

A new report reveals that engaging in physical activity, eating healthfully and drinking coffee can all reduce risks of womb cancer, a disease that affects nearly 50,000 women in the US each year, according to the American Cancer Society.
Authors of the report, which was published by the American Institute for Cancer Research (AICR) and World Cancer Research Fund International, say that worldwide, endometrial cancer - cancer of the womb lining - is the sixth most common cancer in women.
However, in the US, regular physical activity (30 minutes a day) and keeping a healthy weight (BMI between 18.5 and 25) can potentially prevent nearly 60% of endometrial cancer cases, the report shows.
Though womb cancer is mostly diagnosed in women over 60, there is currently no reliable screening system to detect it in the general population.
Symptoms of the disease include abnormal vaginal bleeding or discharge, as well as pain in the lower abdomen during sex.
Keeping a lean body helps reduce risks, but the researchers found that the risks were even lower for women who have never used hormone therapy, according to Elisa V. Bandera, associate professor from Rutgers Cancer Institute of New Jersey and panel member for the Continuous Update Project (CUP).
Bandera also says that evidence from cohort studies suggests that length of sitting time may increases risks, but she notes that more evidence is needed in order to make a firm conclusion.
Bandera adds:
"While additional studies are needed, it is a safe bet that maintaining a healthy weight and engaging in regular physical activity will reduce endometrial cancer risk, as well as having many other health benefits."

Coffee and other dietary choices decrease risk

The report showed that every cup of coffee consumed is linked with a 7% reduction in womb cancer risk. But researchers say more studies are needed.
 
In addition to staying fit, the research showed that drinking coffee can also reduce womb cancer risks.
Elisa V. Bandera says that both caffeinated and decaffeinated coffee is associated with "an estimated 7% reduction in risk for every cup of coffee consumed, based on eight studies."
She says that while the findings are interesting, drinking excessive coffee can also have adverse side effects. For example, Medical News Today recently reported that four cups of coffee a day is linked to death risks.
On the other hand, other studies have shown that coffee intake is linked to lower suicide risks and lower stroke risks.
Bandera notes that "in terms of food choices, eating a diet high in vegetables and low in fat and refined sugars is going to, at a minimum, help with weight control, while probably also protecting against cancer in other ways."

Couple raises money for Calif.



Son’s battle with rare cancer inspires parents’ fundraising effort

By Amanda Roberge CORRESPONDENT

When Shrewsbury native Scott Zenaro arrived in California three years ago, he couldn’t possibly have understood that he was being given a second chance at life.

A rare diagnosis of Ewing’s sarcoma at age 30 led to four long and difficult years, which included a handful of surgeries, 18 months of chemotherapy and 70 days of radiation. By the time Scott was 34, his doctors at Massachusetts General Hospital in Boston had nothing left to offer him. They had exhausted their resources and referred Scott to an oncologist in Santa Monica named Dr. Sant Chawla.

Dr. Chawla was unique in that he offered terminally ill patients a chance to participate in FDA clinical trials, and the family rejoiced in this gem of good news: Scott was one of the few people chosen to be part of a trial for the antibody drug R1507. However, the joy of the news quickly faded, and it became clear that there was one potentially major roadblock. Dr. Chawla’s clinic was in Santa Monica.

In between the East Coast and West Coast there were a number of problems to solve, not least of which had to do with finances. How does a 30-something cancer patient on a fixed income afford a 3,000-mile move to one of the most expensive cities in the country, just to roll the dice with an experimental treatment? The Lazarex Cancer Foundation in Danville, Calif., exists for this exact reason.

“Our mission is to provide resources for cancer patients who’ve been told they have no other options, but who are not yet done with their journey in life and refuse to give up,” said Susan Sappington, director of development at Lazarex. “Our goal on a daily basis is to help build a bridge to hope for not only the patients but to their families, who need to know they have done everything possible for their loved ones.”

When Scott began to question the logistics of his cross-country leap, Lazarex stepped in and provided him with a condo in a beautiful Marina Del Ray community and took on the burden of his medical and living expenses.

“He loved his time in Marina Del Ray,” said Scott’s father, Ron Zenaro. “He became very important to everyone at Lazarex, and of course we are very indebted to them.” Not only was Scott enjoying his role in California as a Lazarex spokesman, he also found that his body was responding well to treatments.

Much to everyone’s delight, Scott took it upon himself to become the self-appointed Lazarex ambassador and welcome wagon for incoming patients.

“He made them feel so welcome,” said Ms. Sappington. “He became an important part of everyone’s experience here, helping them with whatever they needed.”

When Scott’s treatments ceased to work, Lazarex funded a trip to the Philippines for him to receive additional treatment, where his winsome and outgoing character continued to shine on everyone at the clinic.

“He just had so much personality,” said Ms. Sappington. “He made everyone laugh. He was always cracking jokes.”

Scott died on Feb. 24, at 36 years old, after flying home to Boston for a bronchoscopy that doctors hoped would help him continue his life. When all hope was lost and he failed to regain consciousness, his family made the difficult decision to pull his breathing tube and let him be at peace, a long journey over after a courageous and admirable life.

His death was devastating and sudden in its own way, and has left holes in the hearts of not only his parents, siblings and countless friends, but also the people at Lazarex. “We all loved him very much,” Ms. Sappington said.

While Scott’s friends and family continue to deal with the trauma of their loss, Scott’s mother, Carol, has found her own way to give back: crafting beautiful bracelets from beads made of clay, glass and wood. The family has begun pounding the pavement for donations in return for one of Carol’s creations. In fact, she began crafting the bracelets before Scott’s passing, while he was still in the Philippines. During his visit home for Christmas in 2009, Scott commissioned nine bracelets to take back to the clinic for his nurses and staff.

“He called us from one of his appointments after he got back to the Philippines and we could hear everyone yelling ‘Thank you,’ ” said Mr. Zenaro. “But still, the bracelets weren’t that big of a deal until after he died.”

Indeed, production and sales — all executed with love and reverence by a mother who continues to grieve the loss of her youngest child — have become something of a career for Mrs. Zenaro since her son’s passing. Mr. Zenaro is proud to point out that through her craft, the family has already been able to donate more than $13,000 to Lazarex and has no plans to slow down.

“This whole thing has been very devastating,” he said. “(Making the bracelets) is good for her.”

Ultimately, because 100 percent of every donated dollar goes directly to the patients at the Lazarex Cancer Foundation, the family is invested in raising funds in this grass-roots way. Mr. Zenaro, for one, carries his wife’s wares with him everywhere he goes. A natural salesman, he has taken to promoting her product with steadfast enthusiasm.

“The Lazarex Center allowed Scott to lead a dignified, normal life for two and a half years,” he said, adding that Scott became the center’s longest living patient and, ultimately, a huge success story for the experimental treatments he received through the clinic.

School-age drinking 'may increase breast cancer risk'

by Honor Whiteman 


The more alcohol a female consumes between her first menstrual cycle and her first full-term pregnancy, the higher her risk of breast cancer, according to a study published in the Journal of the National Cancer Institute.
 
Researchers analyzed the health history of 91,005 mothers with no history of cancer who were a part of the Nurses' Health Study II from 1989 to 2009.

The study was conducted by researchers from the Washington School of Medicine in St. Louis, Brigham and Women's Hospital, Harvard Medical School, Beth Israel Deaconess Medical Center and Harvard School of Public Health.

In 1989, all women in the study completed a questionnaire on their early alcohol consumption between the following age periods:
  • 15-17 years
  • 18-22 years
  • 23-30 years
  • 31-40 years.
The women were then analyzed over the 20-year period in order to determine their risk of breast cancer.

The analysis showed that over the full study period, 1,609 breast cancer cases were identified, along with 970 proliferative benign breast disease (BBD) cases.


Overall results of the study revealed that a female who averages one alcoholic drink per day between her first menstrual cycle and her first full-term pregnancy increases her risk of breast cancer by 13%.
 
The findings also showed for every beer, glass of wine, or alcoholic shot consumed on a daily basis, a young woman can increase the risk of proliferative benign breast disease by 15%.

The study authors add that although proliferative benign breast tumors are not cancerous, they can increase the risk of breast cancer by 500%.

Breast tissue 'susceptible' during adolescence

Dr. Graham Colditz, associate director for cancer preventions and control at Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine, says:
"More and more heavy drinking is occurring on college campuses and during adolescence, and not enough people are considering future risk. But, according to our research, the lesson is clear.
If a female averages a drink per day between her first period and her first full-term pregnancy, she increases her risk of breast cancer by 13 percent."
According to the researchers, the cells in breast tissue are very susceptible to cancer-causing substances during adolescence and after.

They add that an area of concern is the length of time between the average age a girl begins her menstrual cycle, and the average age of a woman's first full-term pregnancy. The longer the length of time, the more they will drink.
 
"Reducing drinking to less than one drink per day, especially during this time period, is a key strategy to reducing lifetime risk of breast cancer," adds Dr. Colditz.

He adds that further research is needed to determine what can be done to mitigate the risk of breast cancer in young women if they choose to drink. At present, the researchers conclude that reducing alcohol consumption would be the best intervention.

Additionally, they add that school kids should be provided with more knowledge about the effects alcohol can have on breast cancer.

Ying Liu, first author of the study and a School of Medicine Instructor in the Division of Public Health and Sciences, says:

"Parents should educate their daughters about the link between drinking and risk of breast cancer and breast disease. That is very important because this time period is very critical."

New 'Pill' to Help Prevent Breast Cancer

Women at a high-risk of suffering from breast cancer may benefit from a new pill that could help prevent the disease. 

Doctors were given the go-ahead to prescribe the drug in a move hailed by experts as a "game changer".

Women with a family history of the illness will get the drug, costing less than 7 pence a day, after new guidance by the NHS medicines watchdog, the National Institute for Health and Care Excellence, the Daily Express reported. 

Baroness Delyth Morgan, chief executive of Breast Cancer Campaign, said that this is a truly historic moment in the treatment of women at increased risk of breast cancer. 

The drug, either in the form of tamoxifen or raloxifene, could help more than 488,000 women in England and Wales dramatically slash their risk of breast cancer. 

It would be taken in much the same way that daily cholesterol-busting statins are taken by millions of people to stave off heart attacks and stroke. 

Nice updated its guidelines on tamoxifen and raloxifene for particular groups of women and men after a string of scientific studies showed the drugs can stop people getting breast cancer if taken for five years. 

The treatment will be offered to women aged 35 and over deemed to have a high risk (more than 30 percent) or moderate risk (17 to 30 percent) of contracting the illness.

'Cancer Prevention' - In Your Hands



Cancer - A disease that could wipe the smile off many faces and cause the deepest anguish is preventable. It is not an exaggeration that 43% of all cancers are preventable. Sunday, 4 February 2007, is World Cancer Day, embodying the theme - "Today's Children, Tomorrow's World" will focus on strategies for a cancer free world - a precious gift to our dear children.

Cancer is caused due to the unchecked growth of abnormal cells. There are nearly 100 types of cancers, which could afflict any part of the body. The most common types of cancers are - Lung cancer, stomach cancer, liver cancer, colon cancer, and breast cancer. More than 7 million people die each year due to cancer with 70% of the deaths occurring in developing countries. Further, 11 million new cases of cancer world-wide are added each year.

The main objective of the 'World Cancer Day' campaign is to disseminate crucial information about cancer, with focus on 'prevention'. The worldwide campaign will make an appeal to parents, healthcare professionals and policy decision-makers, to go the extra mile towards inculcating healthy lifestyle habits in children, so that they grow up to be healthy adults.

Tobacco and Cancer: A smoke-free environment forms the basic premise of any cancer prevention programme. Nearly 30% of all cancer deaths are caused by the use of tobacco in any form. In the year 2006, almost 5 million people world-wide died due to cancer caused by tobacco. Most of the lung cancers in the world today boil down to the use of tobacco. Statistics show that in several regions of the world, more than 30 percent of children have experimented with tobacco products before they have turned 10. Amid such a scenario, children must be taught about the ill-effects of smoking, use of tobacco and it's far reaching repercussions on health. It might be a good idea for policymakers to enforce higher taxes on tobacco products, to discourage many smokers from the habit. The campaign seeks to bring to the fore, the importance of providing children an environment that is tobacco-free.

Obesity and cancers: Overweight and obesity are important causative factors of certain cancers - esophagus, colon, kidney, breast and endometrium. To prevent overweight and obesity, the importance of healthy diet, with an abundance of fruits and vegetables, coupled with regular exercise, cannot be over emphasized.

Chronic Infection and cancers: Nearly one-fifth of all cancers in the world are triggered by chronic infection. The hepatitis B virus (HBV) could cause cirrhosis of the liver and liver cancer, which is the cause of one million deaths annually. An important facet of every cancer prevention program includes immunization programs for children, which enable maximum protection against such cancers. Nearly, 500,000 cases of cervical cancer diagnosed every year are due to a sexually transmitted virus. About 80 percent of all cervical cancers are reported from developing countries where routine screening, pap smears or treatment is wanting in many aspects. Cervical cancer can be prevented with vaccinations against the human papillomavirus (HPV) and the hepatitis B virus (HBV), capable of offering protection against cervical and liver cancers respectively. It is important to vaccinate girls and young women against the human papillomavirus (HPV) infections, and protect against cervical cancer. Significantly, because both viruses are transmitted through sexual contact, educating children and teenagers about the risks of disease and safe sexual behavior forms an integral part of cancer prevention.

Ultraviolet rays and cancers: Overexposure to the sun is the cause of many types of skin cancers due to the harmful effects of ultra-violet rays. Nearly 3 million non- melanoma skin cancers and 132,000 malignant melanomas are reported world-wide each year. Regular exposure to sun and sunburn during childhood can increase the risk of melanoma in adulthood. White people who expose themselves for prolonged periods under the sun to get tanned are at special risks. Using protective clothing, hats and sunscreen can help protect against the harmful radiation.

A significant aspect of cancer prevention involves educating people, especially children, about the extended benefits of maintaining a healthy weight, staying physically active and avoiding abuse of alcohol. The above factors are also risk factors for other diseases such as diabetes and cardiovascular disease. Therefore a cancer prevention program can be a panacea for prevention of many other lifestyle diseases as well.
