Breast Cancer and Tobacco, the Link!

The list of cancers associated with smoking is a long one: Lung, esophagus, throat and larynx, as well as kidney, bladder, pancreas and stomach. Now add Breast Cancer to the toll.

Until now, studies had not been able to definitively link smoking to breast cancer because of tobacco's double-edged effect. While its carcinogens can trigger tumors to grow in breast tissue, its ability to block estrogen, a hormone that promotes breast cancer, may actually work to suppress malignancies. The latest research clarifies the risk, finding that per menopausal women who smoke had a higher risk of breast cancer than women who did not, but after menopause, women who puffed cigarettes were slightly less likely to develop the disease than nonsmokers. The theory is that postmenopausal women have low levels of circulating estrogen and may benefit further from tobacco's antiestrogenic effects.

Overall, the added Breast Cancer risk from regular smoking at any age was 6%, but that figure shot up for heavy smokers. Women who lit up before age 18 and smoke for three decades or longer had a 25% greater chance of the disease than nonsmokers.

Given the small window of time during which smoking may protect against cancer in the breast, it is a good idea to kick the habit now.

If you happen to be a smoker, I know it is hard to quit smoking but for your health please quit.

Talk with you doctor to find out what medications may be available to help you quit.

My father developed throat cancer and 3 years later died from lung cancer for smoking.

My sister has developed bladder cancer which may be related to her many years of smoking.

Breast cancer does not happen just to smokers but please do anything you can do to reduce your chances of getting it.

Vitamin-D , How much is OK? Cancer Statistics.

With sunblock and self-tanners, Americans are D-deficient but how many vitamin D pills should we be taking. New guidelines for the optimal dietary dose are expected out this fall and the studies on vitamin D's effects on cancer, heart disease and cognition are ongoing. Here is where the science stands on cancer now.

Vitamin D may prevent cancer by suppressing the cell growth and blood vessel formation that feed tumors. At least that is the idea, based on animal studies and analyses of human cells. But trials in which patients take vitamin D have not shown a consistent lowering of cancer risk.

One four year trial of 1200 postmenopausal women found a 77% lower risk of all cancers among those taking calcium and 1, 000 IU of vitamin D a day than among those taking a placebo. A larger study, however, in which subjects took 400 IU of vitamin D -- in the absence of an official daily recommended intake, that is the "adequate" intake for adults ages 51 to 70-- did not show lower breast-cancer risk.

The data are strongest for colorectal cancer: subjects with higher blood levels of vitamin D were half as likely as those with lower levels to develop the disease.

Always discuss the vitamins you take with your doctor before starting them.

Anti-Breast Cancer Pill!

Fish Oil, rich in Omega-3 fatty acids, helps protect healthy people from heart disease and now a new study finds taking fish-oil supplements may also reduce breast cancer risk by over 30% in postmenopausal women.

Omega-3, from dietary sources, trials have been inconclusive and the authors of the study caution that more study is needed before the Omega-3 pills can be used for prevention.

This information is from the July 19th Time Magazine, Health Section, Latest Findings.

Always check with your doctor before adding any supplements to your routine and you may want to discuss adding Omega-3's to your diet.
