Breast cancer is a malignant tumor that originates from breast tissue cells. Although most breast cancers initiate in the cells that line the breast ducts, some begin in the breast lobules and other tissues. As with all cancers, there is a genetic and environmental component of developing breast cancer. Women with defects in the BRCA1 and BRCA2 genes have up to an 80% chance of getting breast cancer. Research has also found that defects in the ErbB-2 gene lead to increased levels of the protein cyclin D1. Cyclin D1 then activates CDK4, which causes proliferation of cellular division. Blocking CDK4 activity may lead to effective breast cancer treatments.
