About 20 percent of all leukemias in the Western world are chronic myeloid leukemia ( CML ). Today's treatments target an abnormal chromosome that causes the disease, but new theories about how to outwit this resilient disease are sprouting.

Heart health can be improved with lifestyle changes - weight loss, exercise and a healthy diet. It may be that these changes also reduce a man's risk of prostate cancer.

Women who are at high risk of developing breast cancer are sometimes prescribed medications that block estrogen, the hormone that drives the most breast malignancies. One such drug is Aromasin ( exemestane ), which new studies show lowers more than cancer risks.

Dietary guidelines are constantly changing. And doctors rarely discuss eating plans with their patients being treated for cancer. A new study shows that eating nothing at all from time to time could be extremely beneficial.

Ovarian cancer can live within a woman's body for some time before showing itself. And sometimes its presence is never really felt. That's why diagnosing the disease is so tricky. Now, researchers have zeroed in on a way to detect ovarian cancer that has returned.

The risk of developing breast cancer increases as a woman ages. The risk of breast cancer returning also increases with age. And increasing age also increases the risk of dying from breast cancer.

Cancer biology overlaps frequently, and some drugs designed for a specific mutation may have multiple uses, as one study shows.

For men at risk for prostate cancer or diagnosed with a slowly progressive prostate cancer, the options to track the tumor are limited. A new urine test may allow men to avoid biopsies.

Metastasis turns cancer into a multi-front war. New research into identifying how cancer travels in the blood is the first step to preventing it.

There has been a lot of controversy in the medical profession over using PSA (prostate specific antigen) level tests for prostate cancer screening. A new test may actually be more accurate than the traditional method.
