Hi, My mom underwent bilateral mastectomy after being diagnosed with stage 0 breast cancer,DCIS. Initially the surgical oncologist said that chemo will not be required as the tumor size was less than 1 cm and that has been removed but now after consulting a medical oncologist in Tata hospital Mumbai , she is being prescribed 16 cycles of chemo and then targeted therapy after every 21 days for 1 year. My mom underwent three surgeries and is very weak, she is not keen on getting the chemo done and is taking tamoxifen as prescribed earlier by our oncologist. Please suggest if chemo can be avoided completely and what are the chances of recurrence of cancer.
Right Breast : ER/PR negative and Her2 positive.
FISH test : Positive
