I have the ATM gene mutation as well.

I have the gene mutation also. They are keeping me on Post Cancer treatment pills for 10 years instead of 5.

I had two pea sized lumps right in the center of my chest about 1 year after my double mastectomy. It could not be determined if it was cancer or not, so I had surgery and they were biopsiied. They were fat necrosis and that was that. I have since felt another lump that it was determined to also be fat necrosis and nothing else has been done.
