There could be any reason please have your provider examine you. You didn't mention how your reconstruction was done or if you have had fat grafts. The lumps I have felt have been oil cysts from dead fat grafts. Definitely talk to your plastic surgeon.

I had two of those that turned out to be fat necrosis once they were removed. But I would definitely check with your doctor to be sure. Good luck!

Thanks for the advice. I saw my oncologist and he ordered an ultrasound. The ultrasound was suspicious so I go for a biopsy on Monday.

Thank you!!
