According to researchers at Boston University's Slone Epidemiology Center, hair relaxers are not associated with increased risk of breast cancer in black women. The findings will be published in the May issue of Cancer Epidemiology Biomarkers & Prevention.

Researchers announced today that there is strong evidence a chemical referred to as hexavalent chromium, or chromium 6, causes cancer in laboratory animals when it is consumed in drinking water. The two-year study conducted by the National Toxicology Program (NTP) shows that animals given hexavalent chromium developed malignant tumors.

Are soy products healthy additions to a person's diet, safe alternatives to hormone-replacement therapy or cancer-causing agents? The answer, according to University of Illinois food science and human nutrition professor William Helferich, is, "It depends."

The Mount Sinai Medical Center is the only hospital in New York City using the Novalis Shaped Beam Surgery System on spinal cancer. Novalis is the most advanced Stereotactic Radiosurgery(SRS) technology available to treat cancer tumors in the spine.

A Web-based program that provides prostate cancer patients with information about different treatment approaches may make deciding which path to follow a little easier, Medical College of Georgia researchers say.

A gene thought to be essential in helping chemotherapy kill cancer cells, may actually help them thrive. In a new study of chemo patients, scientists at the Georgia Institute of Technology and the Ovarian Cancer Institute found that 70 percent of subjects whose tumors had mutations in the gene p53 were still alive after five years. Patients with normal p53 displayed only a 30 percent survival rate.

While regular multivitamin use is not linked with early or localized prostate cancer, taking too many multivitamins may be associated with an increased risk for advanced or fatal prostate cancers, according to a study in the May 16 issue of the Journal of the National Cancer Institute.

While one in four cancer survivors participates in a support group after diagnosis, use of support groups varies considerably by cancer type, and few survivors receive referrals to such programs from their physicians, according to a new study.

Since 2000 mammography rates have declined significantly in the United States, according to a new study. Published in the June 15, 2007 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study by Dr. Nancy Breen from the National Cancer Institute and co-authors confirms that screening mammography rates to detect breast cancer fell by as much as four percent nationwide between 2000 and 2005.

St. Jude researchers discover that variations in genes that affect the behavior of leukemia chemotherapy drugs in the body are linked to drug toxicity, a finding that will likely help clinicians predict how patients will respond to specific agents

Proline dehydrogenase is important because it plays a role in apoptosis, the process of cell death, by enabling the creation of superoxide, a highly reactive electron-rich oxygen species. Superoxide is involved in the destruction of damaged cells and therefore is important in preventing the development and spread of cancer. The protein proline dehydrogenase "opens up to allow oxygen to 'steal' electrons" and create a superoxide, said Tommi A. White, an MU doctoral student in biochemistry.

People who use Swedish moist snuff (snus) run twice the risk of developing cancer of the pancreas.
