TUESDAY, Feb. 6 (HealthDay News) -- The U.S. Food and Drug Administration has approved a test designed to predict the chances of breast cancer returning or spreading within five to 10 years after a woman's initial cancer.

A new genetic test can tell doctors which breast cancer patients need to undergo the discomfort of chemotherapy -- and suggests many women don't need to, researchers said on Friday.

A genetic test for patients with early breast cancer can identify that only some of them will be helped by chemotherapy, but for those women the benefits far outweigh the drawbacks, researchers said on Friday.

Extra copies of a certain gene found  in about a third of breast cancers may be responsible for their  unchecked growth and survival, researchers reported on  Thursday.

The treatment that more cancer patients receive may one day depend on their genes. With an increasing number of biological clues available, doctors hope they will be able to customize more patients' treatments based on their genetic profiles.

Scientists have identified a gene variation found in about 13 percent of women of European descent that reduces their risk of developing breast cancer, a study released on Sunday said.

A genetic test that grades breast- cancer aggressiveness also identifies low-risk women who don&#39;t need chemotherapy, potentially sparing 50,000 each year from a toxic treatment that doesn&#39;t help them, researchers said.

Scientists have discovered a new cancer-causing gene that they believe could be a molecular master switch for the disease.

U.S. health officials approved a genetic test on Tuesday that can give women with early breast cancer an estimate of whether the disease is likely to return in five to 10 years.

A new technology that counts cancer  cells in the blood helps predict the success of breast cancer  treatments more quickly and more reliably than established  methods, researchers reported on Wednesday.

Scientists in Britain have identified a  genetic mutation involved in certain types of lung cancer and  said the breast cancer drug Herceptin might work in patients  who have it.

Two genes may identify who will respond to a breast cancer chemotherapy treatment, research suggests.

The first genetic map of colon and  breast cancer shows that nearly 200 mutated genes -- most of  them previously unknown -- help tumors start, grow and spread,  U.S. researchers reported on Thursday.

A painstaking scan of the DNA of  tumor cells shows hundreds of previously unsuspected genes are  involved in cancer, researchers said on Wednesday in a finding  that offers new ways to fight the disease.

Women with a high genetic risk for breast cancer run a better chance of having it detected with magnetic resonance imaging than with mammography and other methods, researchers said on Tuesday.

Scientists have identified a protein in urine that has shown some effectiveness as a diagnostic test for breast cancer. But breast cancer experts who have seen the study, to be published soon
