Sorry to hear about your problem. Femara
reduces the chances of cancer coming back by almost 40% and also prevents the risk of getting cancer in the other breast. If you discontinue this medicine, there is a significant chance of the cancer coming back. Did you receive chemotherapy
after your surgery? If no chemotherapy was given, then it is all the more important that you continue taking femara. The total duration of treatment with femara is 5 years.
I hope I have answered your question.
