2nd time but different

Hi all, Well this is a pretty cool platform. I had breast cancer in 1994 34 yrs old and had a Lumpectomy. Chemo 6 months, radiation 6 weeks, then 6 more months of radiation and put on tamoxifen. My cancer grew fast, size of a grain to almost a quarter in a week. By the end of treatment Very draining but I made it and I am now 67. Unfortunately I just got a mammogram with 2 spots on Lumpectomy breast. I had one biopsy so far and damn its cancer. Invasive Mammary Carsinoma. I will get the other biopsy next week. Unsure what will be the treatment and I just retired. I am not a happy person. Has anyone had this and what will the possible treatment be??? Thanks kath
