So from there you could have three or four different drugs that behave differently on these patterns. For example, Herceptin is a receptor drug that came on the market last year. It's a very targeted molecular drug that focuses on a receptor related to one gene. So it's not so far away. One of the patients was a man.
Men can get breast cancer.
These genes are associated with male breast cancer. It's very rare because they don't have estrogen. Mainly the X chromosome and female patterns of estrogen metabolism. There are many other genes interacting or modifying that may affect receptor molecules. The biochemical patterns are just starting to be filled in.
