Breast Cancer

A new drug trial has been launched in Britain aimed at finding a way to prevent breast cancer in women who are high at risk.

British scientists say the drug, Anastrozole, represents the next big step in fighting breast cancer. The disease kills more than 13-thousand women each year in the United Kingdom. A ten year study will involve 10-thousand healthy women who are at an increased risk of being diagnosed with breast cancer.

Researchers believe the drug, marketed under the name Arimidex, could reduce a woman's chances of developing breast cancer by 50 percent. The drug is aimed at post-menopausal women. It works by blocking the production of estrogen.

Some of its side effects include hot flashes and sweats....that mimic symptoms of menopause. The study is being led by the charity, cancer research U-K.

Breast cancer is the most common cancer in women with more than one million cases diagnosed worldwide each year.
