Come clean to your doc, or you could risk more than a red face. Many patients see no harm in fibbing about whether or not they smoke, take vitamins or how much they drink. But this information should not be left out. In particular, women who do not tell their doctors that they smoke rob themselves of an accurate determination of their risk of blood clots. Doctors who know that their female patients smoke tend to recommend lower-risk methods of contraception, such as diaphragms and IUDs.

It's well known that cigarettes can cause lung cancer. A nd yet, some people smoke like a chimney their entire lives and never get the disease. Now a sweeping search for an explanation has yielded a clue: Three studies have found a marker in the same region of DNA that appears to raise the risk of lung cancer. But the researchers disagree on whether the gene involved directly causes lung cancer or does so by influencing how easily people get hooked on tobacco.
