The development of a new cancer drug involves many years and millions of dollars. That’s one of the reasons why scientists are looking at new uses for existing drugs and combining approved drugs. This approach may work well in treating two really bad cancers.

The need for radiation treatment after a lumpectomy has been studied for years. Current treatment guidelines say radiation is not necessary for older women with early breast cancer. A new study suggests that this may not be the case.

A compound found in vegetables such as broccoli, cauliflower and kale has been studied for its effect on cancer. Recently, its potential benefits may have been expanded.

A lot is being done these days with combining medications, or changing the order in which they're taken. A new dual approach appears to be effective against deadly dual cancers. And the findings may apply to a number of cancers.

The U.S. Food and Drug Administration has approved a drug to be used for postmenopausal women with advanced hormone-receptor positive and HER2-negative breast cancer.

Obesity. Obesity. Obesity. It's spreading everywhere and touches most every chronic health condition. Now researchers find obesity could affect how well long-term breast cancer treatments work.
