I am sorry to hear about your sister-in-law. I had metaplastic carcinoma diagnosed a year ago. Since then I have had 6 rounds of TAC chemotherapy, a bilateral mastectomy,and 33 radiation treatments. I have had a wonderful team of doctors at Watson Clinic in Lakeland, Florida. At no time have they discouraged me or given me any reason to believe that my chances of recurrence are much greater than most forms of cancer. However, I will say that I did not have any lymph nodes involved nor had my cancer metastacized anywhere else. All of my recent check-ups have been positive and my doctors have gone so far as to say I'm currently cancer-free. My lump was large (5cm) and the chemotherapy did reduce it considerably (to 1.8 cm) before my surgery. I could have had a lumpectomy, but I chose to go ahead with the bilateral mastectomy anyway.
Every case is different so it's hard to say what will work for your sister-in-law. You said she was diagnosed over a year ago. What type of treatments has she had so far? Has the cancer metastasized or spread to the lymph nodes?
I wish for the best for both of you. Please let me know if I can answer any other questions or be of further support for you.
