Thanks for this question! I have the exact same issue. Had my lumpectomy in June last year followed by radiation in Sept. Just recently started feeling some minor pain and tenderness at the side and top of my breast. I hoped that was normal. I have my 6-month follow-up mammo and appt. with my oncologist next week, so I was waiting on that. Good to know it is common.

Hello all, I just had the breast ultrasound and thankfully everything came back normal. The doctor said it could be pain associated with tissue regeneration,scar tissue, effects from radiation, all part of healing .

@A MyBCTeam Member glad that you are having an ultrasound concerning your BC journey and the issue that you are having now. Hoping that you recieve great news. Have a nice day.

I've had that happen a bunch of times over the 9 years I've had breast cancer. I see the oncologist every 3 months, so if the sore spot has lasted a while and still hurts then at my appointment I have my doctor check it out. My PET scans happen between the oncology visits so if I have an active sore spot at that time I have the radiation oncologist look at my scan.

I had a lumpectomy in July 2025 also. I finished my radiation at the end of September. I still have some pain and sensitivity depending on what I do. When someone gives me a big hug…. Ouch! All the reasons explained are what my surgeon told me. I was a little concerned at first as some of the area felt like a lump(first thought, is the cancer back). Continue to protect the area and wear a supportive bra so the breast is not dragged down due to gravity ( can effect the pain and healing and scarring, as gravity pulls on the tissue)
