I'm a bit skeptical just reading the article titled A Laugh a Day Might Keep Death Further Away. In a recent Norwegian study, adults who have a sense of humor showed to outlive those who don't find life funny. I don't know about this -- I can think of a lot of miserable people who lived very long lives!

I love to laugh. Watching comedians is one of my favorite things to do, however I don't think that is going to make me live any longer than other breast cancer survivors.

The study said that the survival edge is particularly large for those with cancer. In this study the researcher claims that a great sense of humor cut someones chances of death by about seventy percent compared with adults with a poor sense of humor.

Sven Svebak, of the medical school at Norwegian University of Science and Technology, says that past studies have shown that humor helps people cope with stress and keep a healthy immune system during stressful times. He believes that could promote survival.

William Breibart, psychiatry chief at Memorial Sloan-Kettering Cancer Center in New York city, is skeptical also. Breibart says that in the twenty two years of treating cancer patients he met a lot of funny people who died of cancer pretty quickly. He says that stage of disease and aggressiveness of tumor matter far more than a person's sense of humor.

He did add that someone who can see humor in bad side effects of chemotherapy might stick it out more for treatment and that can be a way humor affects survival.

This sounds too much like -- you need to have a positive attitude -- cancer survivors are not particularly fond of hearing that our cancer came back because we didn't have a positive attitude or we didn't have a great sense of humor -- but laughter does make life more enjoyable!

As if gum disease is not a painful enough experience, a Harvard study shows the disease can more than double the risk of pancreatic cancer. Additionally, those with a history of gum disease and recent tooth loss have a 2.7-fold increase in risk.

Previous studies have linked gum disease and pancreatic cancer, but smoking -- which contributes to both diseases -- has never been taken into consideration.

Researchers in this study, who controlled for smoking, followed 51,529 men for 16 years and found those who reported gum disease were 64 percent more likely to have pancreatic cancer. Nonsmokers with gum disease were twice as likely to develop the disease.

It was also determined in the study, published in the January 17 issue of the Journal of the National Cancer Institute, that the more severe the gum disease, the higher the cancer risk.

While it is not clear why gum disease is linked to cancer risk, researchers believe perhaps long-term gum infections trigger body-wide inflammation -- and inflamed tissues send chemical signals that promote tumor growth.

I have a cabinet full of supplements I've never taken. I've never been convinced they will do much for me -- other than add an easy-to-forget routine to my day -- and doctors have typically advised me that a healthy diet will deliver just about everything I need for optimal functioning. I still wonder sometimes if I get enough calcium and at times I have taken iron supplements when doctors have determined I lacked appropriate iron levels. But I have never wondered about all the other pills and powders and liquids that claim to promote health -- and sometimes prevent cancer. And after reading a recap of a study in the September 2006 Oprah magazine, I am further convinced that supplements are just not for me.

A report from ConsumerLab.com (CL), a company that tests and certifies supplements, suggests that some people might be ingesting too much lead as they try to keep cancer at bay. CL randomly selected various green tea preparations from store shelves, websites, and direct marketers and found that two out of four contained what is considered unacceptable levels of lead. Green tea products they recommend avoiding are Futurebiotics Premium Extract Standardized Green Tea tablets and Herbal Select Standardized Green Tea Extract. Products found to be totally free of lead are Life Extension Mega Green Tea Extract, Nature's Bounty Green Tea Extract, Pharmanex Tegreen 97, and Puritan's Pride Green Tea Extract.

Experts believe that some supplements may help prevent cancer. But most testing is done on food so we can't be entirely sure about the safety of supplements. Their advice is this -- make a change through a healthy diet rather than supplements. This is just what I plan to do.

Women diagnosed with cervical or uterine cancer, or are at higher risk for these cancers, need to require their sexual partners to wear a condom during sex, as semen appears to speed up the progression of cervical and uterine cancer, according to the results of a study done by UK Medical Research Council researchers.

Researchers found that high levels of prostaglandin present in semen might promote and fuel the growth of certain cancers for women. The hormone prostaglandin is produced by the reproductive glands of women and the levels of prostaglandin primarily regulates how much the uterine lining thickens and sheds each month. Semen contains a prostaglandin concentration 1,000 times higher than women normally produce in their own bodies.

The introduction of semen might promote cervical cancer and uterine cancer, as cervical and uterine cancer cells have prostaglandin receptor molecules on their surfaces. While it is known the human papilloma virus (HPV) might lead to cervical cancer, the researchers feel there might be other factors that fuel the development and spread of these cancers for women. Many women are infected with HPV at some point in their life, but not all women will go on to develop cervical cancer from the infection.

Sometimes drinking alcohol is healthy. And sometimes drinking alcohol is harmful. Studies show that one drink per day -- compared with no drinking at all -- can reduce a woman's risk for heart disease and stroke by 50 percent. And other research indicates that older women who drink moderately have better cognitive skills. But there are also downsides for women who drink even moderate amounts of alcohol.

Even as little as one-half drink per day increases the risk of breast cancer -- possibly because alcohol raises estrogen blood levels which can promote growth of breast tumors. Women are also more likely than men to become dependent on alcohol and to experience other consequences too -- including damage to the brain and other organs. One in 13 adults in the United States has a serious alcohol problem -- and at least six million of these adults are women. And because the risk for alcohol-related health issues increase with age, older women should be especially careful of their alcohol intake for the purpose of maintaining health and limiting the odds of a breast cancer diagnosis.

In the interest of balancing the healthful and harmful effects of alcohol, The Harvard Women's Health Watch suggests that women over the age of 65 limit themselves to one drink per day. Or less.

A reader left a comment the other day on the Cancer Blog post death by cancer dims outlook of promise, hope, survival. It was positive and supportive and inspiring -- and sad too. The reader shared that her mother passed away in February after a year-long battle with gallbladder cancer. She wrote that her mother handled her diagnosis, chemotherapy, transfusions, medications -- and her final days -- with true grace. And this is a big deal. Because there is not much information floating around on the topic of this cancer. So this woman didn't have much to cling to. Like I do. As a breast cancer survivor, I have mounds of resources at my disposal. I have books and magazines and websites and blogs that devote generous coverage to breast cancer. There are walks and runs and yard sales and fashion shows and other fundraisers that make breast cancer survivors the lucky recipients of extensive research and study. I see pink ribbons all over town and license plates on the roads and clothing and hats and even tennis shoes that promote breast cancer awareness. I could go on -- and on and on.

Gallbladder cancer is rare. So perhaps that's why there is not an abundance of information on the disease that has no known cause or test to detect its presence in the body. The American Cancer Society estimates that about 8,750 new cases of gallbladder cancer and bile duct cancer (excluding bile ducts within the liver) will be diagnosed in 2006 in the United States. And about 3,260 people will die of these cancers in 2006. Of these new cases and deaths, about half are due to gallbladder cancer, which affects predominantly women and those who are older than 65. Diagnosis of this cancer is difficult because symptoms do not often surface until the late stages when aggressive treatment becomes necessary. Surgery, chemotherapy, and radiation therapy are typical treatment tools, along with palliative therapy to help control or reduce symptoms. There are also drugs currently under study in the areas of both targeted therapy and immunotherapy.

It's good to know that gallbladder cancer is rare -- and that it takes far fewer lives than breast cancer and other diseases -- but for the unfortunate ones who are diagnosed with this life-threatening illness, the lack of information and resources is a truly an unfortunate side effect.

According to experts, nicotine alone is not a cancer-causing agent. However, Srikumar Chellappan and University of South Florida researchers report that nicotine does promote cancer by stimulating cancer cells in the growth of lung cancer tumors.

The researchers explain that tobacco smoke contains a variety of tobacco-specific carcinogens, many of which are derivatives of nicotine that are formed during the curing of tobacco. Researchers studied receptors that bind nicotine, known as nicotinic acetylcholine receptors, nAChRs, and found this process to be in part responsible in the cell proliferation and the progression of lung cancer tumors.

The research article Nicotine induces cell proliferation in its entirety is available online as a PDF document.

The Cancer Blog is one of three health blogs where we post information and resources in news you can use to promote good health in the prevention and management of disease; advancements in research; features about people and human interest stories; products and services; and announcements of events. Really, if it is health-related in interest, we are likely to post about it.

To help you stay current of all three of our health blogs, we would like to share some of the posts that appeared on both The Cardio Blog and The Diabetes Blog in a retro review of the first week in July. Welcome back from the weekend. To your good health!
