Breast cancer is the second most common cancer among American women today. According to a report from leading U.S. experts, breast cancer is not a single disease. It consists of four subtypes, which vary by age, race, and other factors. Each subtype responds differently to various treatments and has different survival rate. The study found that non-Hispanic white women were more likely to have the least aggressive form of breast cancer, while non-Hispanic black women were more likely to have the most aggressive form. The author of the report believes that the discovery of these four subtypes will improve breast cancer diagnosis and provide treatments that will have a better chance of treating and improving the mortality rate of breast cancer..
