My mom 66 just diagnosed with breast cancer, metastasis to bones, stomach&lung t3n2m1. Put on tamoxifen for 2 mnths. Can she benefit from surgery? Whats her survival rate in years? How to extend her life?

Need more than that. Yes if primary tumor is not removed , yes she will debunking will help , needs more than tamoxifen , speak to the oncologist for chemotherapy . Recent advances in chemotherapy changing the survival rate from 23% for better . Good luck.
