Have stage 3 grade 3 ductal breast cancer with 1 lymph node cancerous. Tumour was 49mm. Had Mastectomy, lymp node removal and reconstruction 4 weeks ago. I’m 54 and post menopausal. The wait on the oncotype results is driving me crazy. Cant think of anything else. Wondering will i need chemo or not? Anyone in a similar situation please? Thanks ️
