** Obese people less likely to survive colon cancer

According to a new report, people who are physically inactive and obese around the middle have poor odds of survival after diagnosis of colon cancer.

"We have now shown that the change habits that are known to reduce the incidence of colon cancer can also reduce the mortality in cases diagnosed with the disease," Dr. Andrew MM Haydon told Reuters Health. "This strengthens the argument supporting the public health message 'healthy living .'"

Haydon, from Monash Medical School in Melbourne, Australia, studied records of more than 40,000 patients diagnosed with colorectal cancer between 1990 and 1994.

Patients who got regular exercise before colorectal cancer was found were 31 percent less likely to die from cancer than non-exercisers, the researchers report in the medical journal Gut. In fact, 73 percent of exercisers survived at least five years, compared with 61 percent of non-exercisers.

Such an improvement of survival "is at least as large as" as is usually achieved by add-on chemotherapy.

a higher percentage of body fat, bigger waist circumference, and / or greater weight were also associated with worse survival, according to the report.

** The study shows short-term improvement of sexual life in prostate cancer survivors

It is well known that many people who have undergone prostate cancer treatment (surgery or radiation therapy) have sexual disfunkcije.Nedavna study of 84 prostate cancer survivors tried to determine the effect of the treatment interventions such as counseling.

The study showed that a large percentage of those who completed four therapy reported sexual functioning 3 months later. Consultation focused on better communication between partners, ED treatment options, and methods of enjoying sex in spite of ED.

Both partners reported improvements in their sex lives for up to 3 months later. There is also an increasing number of people using ED treatments such as Viagra.

, however, after six months, improvements began to decline. Researchers have speculated that couples often revert to old habits, and there might also have been greater reliance put on a "magic pill" solution. Drugs such as Viagra tend to have lower success in prostate cancer survivors, so when the drugs stop working couples may adopt a defeatist attitude.

** Vitamin D helps in the fight against cancer, report says

research team from San Diego Moores Cancer Center led by Dr. Cedric Garland recently concluded that vitamin D deficiency is often associated with different types of cancer. Dr. Garland is now advising people to increase their intake of vitamin D through diet or vitamin supplement.

The research team reviewed 63 studies conducted between 1966 and 2004 on the relationship between vitamin D and certain types of cancer. The report concludes that vitamin D deficiency is a factor in several thousand deaths due to colon, breast, ovarian and other cancers annually.

The report recommends a higher intake of vitamin D, either in the form of supplements or eating certain foods such as fortified orange juice, yogurt and cheese. This is particularly the case with people in northern latitudes where there is less sun exposure. African Americans are more prone to vitamin D deficiency because their skin pigment reduces the amount produced in the body.

Observers welcomed the University of California study but warned that the kidney and liver damage can occur from too much vitamin D.

"natural" form of the vitamin, called D3, is normally produced in the skin after sun exposure, but is also obtained from certain foods such as oily fish, margarine and meat.

** Resveratrol found in grapes helps fix our aching joints

Researchers at the American College of Rheumatology in San Diego, California, found that resveratrol found in red wine seems to halt cartilage damage caused by osteoarthritis, and accelerate recovery.

is considered to be oxygen-rich particles in the blood cause serious damage to body cells in a similar way rust rots a car. Resveratrol is a powerful anti-oxidant that seems to function as a way to prevent this type of injury.

research found that resveratrol resulted in a reduction of between 50 and 90% of the production of chemicals that cause inflammation in the joints. It also enhanced the production of specific proteins that are part of the connective tissue in joints.

Red wine has other beneficial effects on the body. Contains polyphenrols that reduce the amount of LDL cholesterol in the arteries. It also increases the amount of good HDL cholesterol.

tannins and resveratrol, an anti-oxydants found in red wine, help protect against cancer and slow tumor growth.
