My mother is having metastatic (carcinoma) breast cancer in left breast and was very slightly spread to lungs also. Found it in last three months back but she doesn't have any issues on her health. ER,PR & HER2 are positive.. Currently she is under going on the target therapy which is INJ TRASTUZUMAB and taking the tablet of hormone therapy. Already 3 cycles have been completed.
However,Our oncologist suggested to continued with the TRASTUZUMAB INJ forever as already spread to lungs and no need to go for surgery on breast.
What's your s suggestion on this?
