A recent study, presented at the annual meeting of the American College of Chest Physicians meeting in Vancouver, suggests that diet and exercise may have different effects in cancer risk depending on a woman's smoking status.

Researchers at the Faculty Hospital Bulovka in Prague had interviewed 533 female lung cancer patients at the hospital and compared them to 1,971 women who did not have lung cancer to evaluate the impact diet and exercise had on lung cancer risk among women.

They revealed that eating dairy products, vegetables, apples, drinking milk or wine, and exercise were found to be protective against lung cancer among women smokers. Drinking black tea also seemed to protect against the disease in nonsmoking women.

Although milk and dairy products, vegetables, apples, wine, and exercise all showed a clinically significant protective effect among women who smoked, it did not show an effect among nonsmokers. Black tea showed a protective effect for nonsmokers, but no such effect for women who did smoke.
