Do not stop: Letrozole (femara) is a non steroidal armatase inhibitor decreases estrogen production do not stop with out talking to your oncologist, any cancer in remission may recur if medications are stopped with out your doctors advise.

Talk to your onc: Your oncologist would be the best one to answer this question. It's not a good idea to stop taking med without a discussion with the prescribing physician, especially when cancer is involved.

Higher than if u...: ...Stay on femara (letrozole). To be more direct, your question cannot be answered since we don't have info re: your stage, rx to-date, personal health, etc. Regardless, people sometimes minimize the effectiveness of aromatase inhibitors--they are potent chemotherapeutic agents, proven to help cure breast cancer. The current recommendations (5 years) are based on sound clinical trials. Please don't stop.

Agree with previous comments, don't stop. But just to clarify, the Femara has nothing to do with the Her2 positive state. It is for Estrogen positive breast cancers. The Her-2 positive is treated with different medications. You can have both, estrogen positive and Her-2 positive cancer.
