I've had a Grade 3 cancer. I had a bilateral mastectomy in Dec 2011 and lymph nodes removed. The cancer wasn't in the nodes. I've started Arimidex. The oncologist gave me the OPTION of having 4 cycles of chemo as well - Taxotere and Cyclophosphamide. I have to decide by tomorrow as apparently there is a 3 month window of time between diagnosis and treatment. I am worried about the permanent damage of these drugs such as kidney damage. Also I don't know if I should even have the chemo or not. Everytime I decide to have it I think I am silly because it could cause permanent damage. Then I think if I don't I haven't done everything in my power to get rid of any stray cancer cells! Can anyone talk to me who's been in a similar situation? Please?
