Hi, sorry to hear about your husbands news. I am a male breast cancer survivor (5.5yrs). I was informed of a grade 2 breast cancer shortly after biopsy at age 60. Not good news and very scary at the time. It would be nearly a week later before I had findings from pathology to know more about the specifics of the cancer. I really didn't know more, but the breast cancer care team did. It's a nerve wracking time waiting for the details to know what the treatment plan may be, but do try to remain calm.
For me the journey included surgery (a lumpectomy), followed by radiation, then 5 years on a drug called Tamoxifen. I know it's a scary time, but give time for detail to surface. There is light at the end of the tunnel. If your husband would like to be in contact with another male that has lived through this disease, feel free to reach out to me.
