My sis had stage111B, 11/2001.5cm tumor along with some nodes infected. She had a mastectomy, chemo and radiation. We have just found out she it has shown up in her lung. She is mentally retarded so all decisions have to be made by me. She is 52yrs old. The doc said no to more chemo or radiation. Wants to start her on another pill other than Tamoxifen. The CT scan detected nodules have grown in the last month. A biopsy is being done next week. He feels it is the cancer because of the CT scan and her blood levels are elevated. What questions do I ask????? You know the one I DO want to know. What is her life expectancy from here? Do I ask it, will he know???? I am her caretaker as well as my mom...80yrs old, and brother that is mentally slow. What do I do??? I am so scared and want to do the right thing. Thanks.
