Laboratory work in animals showed limited activity when statins were given to prevent breast cancer, according to a report in the February issue of Cancer Prevention Research, a journal of the American Association for Cancer Research.

Researchers of the Catalonian Institute of Oncology (Spain) and the University of Granada (Spain) have discovered that extra virgin olive oil may help to combat breast cancer, according to a paper published in the last issue of the renowned scientific journal ‘BMC Cancer’.

Chemotherapy is an integral part of modern cancer treatment, but it's not always effective. Successful chemotherapy depends on the ability of anticancer drugs to escape from the bloodstream through the leaky blood vessels that often surround tumors.

Dr. Michael Lisanti and colleagues at Thomas Jefferson University found that extended lactation protects again mammary tumor development. These findings are presented in the February 2009 issue of The American Journal of Pathology.

Canadian researchers have identified a new protein in the progression of breast cancer. According to a recent study from the Université de Montréal and the University of Alberta, published in the Journal of Biological Chemistry, the protein ARF1 plays a critical role in cancer cell growth and the spread of tumours.

The molecular details of Aromatase, the key enzyme required for the body to make estrogen, are no longer a mystery thanks to the structural biology work done by the Ghosh lab at the Hauptman-Woodward Medical Research Institute (HWI) in Buffalo, New York.

Scientists at the University of Arkansas for Medical Sciences (UAMS) hope to begin clinical trials this spring on a breast cancer vaccine.

Dr. Charles Clevenger and colleagues at Northwestern University have uncovered that cyclophilin B may contribute to progression in breast cancer. Their report can be found in the January 2009 issue of The American Journal of Pathology.

Early-stage breast cancer patients with HER2 positive tumors one centimeter or smaller are at significant risk of recurrence of their disease, compared to those with early-stage disease who do not express the aggressive protein, according to a study led by researchers at The University of Texas M. D. Anderson Cancer Center.

Research out of the Ireland Cancer Center of University Hospitals Case Medical Center has found that the vast majority of triple negative breast cancers express the MUC-1 target.

Mayo Clinic researchers have discovered that a chemical known as endoxifen appears to be the primary metabolite responsible for the effectiveness of tamoxifen in treating breast cancer, and that it works against cancer in an entirely unexpected way.
