Increase of other cancers with anastrozole?


Question from DBryant: The ATAC 10-year update stated that there were more cases of colorectal (66 vs. 44) and lung cancer (51 vs. 34) among women taking anastrozole. Why is this so?
Answers - Eric Winer, M.D. I don't think there is any biologic reason, and results like this can result from chance alone. I can't say for sure it is just the result of chance, but that is quite possibly the case. Any woman with or without breast cancer needs to have a relationship with a primary care doctor and receive good medical care which does include screening for colon cancer after the age of 50.
