Hi, My mom has recently been diagnosed with IDC grade 2, invasive tumour in dermis and all first 8 lymph nodes tumour free with TNM
Greetings. If a complete mastectomy has been done and nodes are free of tumor and the tumor size is small(as in your case), then radiation therapy is not required. Now comes the question of chemotherapy. First she has HER-2/new status of 2+. So a FISH test is required to confirm whether she is HER-2 positive or not. If FISH test comes out to be positive (a bad sign) then I will suggest chemotherapy plus targeted therapy for HER-2(trastuzumab Chat Doctor.  If it does not come positive(good sign) then trastuzumab is not required and requirement of chemo will be decided by another test called ecotype DX. if ecotype DX is high then chemo is required otherwise not. Now comes the question of anti-hormonal therapy. She requires 5 -7 years of anti-hormonal therapy as she is ER positive. Hope that solves your queries. Regards
