Scientists Zeroing In on Third Breast-Cancer Gene

article

Researchers have discovered more about a breast-cancer gene that could be as important as the BRCA1 and BRCA2 mutations in determining a womanΓÇÖs likelihood of getting breast cancer. An international team of 17 researchers, led by the University of Cambridge, said that the gene, PALB 2, could be a candidate to be ΓÇ£BRCA 3.ΓÇ¥ They said that women with the gene have an average one in three chance of developing breast cancer by the age of 70. The findings were reported in the New England Journal of Medicine. Although itΓÇÖs been known for a while that PALB2 was l

Exposure To Nighttime Light Could Be Dangerous for Breast-Cancer Patients

article

The breast-cancer drug tamoxifen is useless if a patient is exposed to even dim overnight light, according to a new study. But it can become effective during the same period in combination with the hormone melatonin. Researchers from Tulane University School of Medicine published the study in the journal Cancer Research. It is the first study to show that melatonin, which regulates sleep and wake cycles, is essential to tamoxifenΓÇÖs success in treating breast cancer. But melatonin doesnΓÇÖt work if itΓÇÖs shut off by exposure to light at night.

Hope For Treating A Deadly Breast-Cancer Gene

article

Researchers have discovered that a gene, previously not linked to breast cancer, plays a central role in the growth of triple negative breast cancer. Targeting that gene, the research indicates, could lead to a new approach for treating that form of the disease.  Triple negative breast cancer, which accounts for 20 percent of all breast cancer cases, often has few treatment options.

Comprehensive Care Needed for Breast-Cancer Survivors

article

Older breast-cancer survivors need comprehensive care to help them fight heart disease, osteoporosis and high blood pressure, according to new research. Women in this category are likely to face these illnesses after their diagnosis of breast cancers. Because of that, they should watch their weight and get regular exercise. The kind of cancer treatment the women received may be a factor, as well as their weight and age.
