MONDAY, Oct. 18 (HealthDayNews) -- A new study adds more weight to the cancer risks posed by hormone therapy by finding that the menopausal treatment also makes breast cancer harder to detect.

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.

Women with a genetic predisposition to breast cancer who are successfully treated for the disease may still be at high risk for ovarian cancer, says a University of Toronto study.

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.

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

The risk of breast cancer among women carrying the well-known BRCA mutations is also affected by other genes, researchers said on Tuesday.

NEW YORK  - A variation in a gene that  regulates inflammatory activity is associated with  susceptibility to prostate cancer, Swedish researchers have  shown.

Women who put on a lot of weight at any stage of adulthood increase their risk of breast cancer, likely because the hormone estrogen accumulates in the acquired fat and promotes tumors, researchers said on Monday.

By Peh, Wendy Y X Reimhult, Erik; Teh, Huey Fang; Thomsen, Jane S; Su, Xiaodi  ABSTRACT Estrogen receptors are ligand-activated transcription factors that regulate gene expression by binding to specific DNA sequences.

NEW YORK  - Professionally led support  groups may ease anxiety and depression in women who carry gene  mutations linked to breast and ovarian cancers, a new study  suggests.

A genetic mutation that raises the  risk of breast cancer is found in up to 60 percent of U.S.  women, making it the first truly common breast cancer  susceptibility gene, researchers reported on Sunday.

MONDAY, Nov. 15 (HealthDayNews) -- Data on nearly a million families suggest that mutations in BRCA1 and BRCA2 genes -- which are strongly linked to some breast cancers -- may also confer a slight increase in risk for pancreatic, prostate and stomach cancers.

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.
