Puckering along scar line

Hi everyone, I’m after some advice. I’m just over 9 weeks post lumpectomy for ER+ PR+ primary bc. Margins and lymph nodes were clear and I started radiotherapy last week. I’m 2 rounds down with 3 to go but noticed a puckering along the scar line on my breast. It wasn’t there before and I wondered if it’s just a side effect of the radiotherapy? I really don’t want to bother anyone if it’s nothing but I’m a terrible panicker at the best of times. Has anyone else experienced something similar once radiotherapy started?

Hi Sharon,
I’m a year post radiotherapy now and I noticed the same at the time, one of the lovely nurses ensured me that it can take up to a year until the breast heals and slight puckering is just part of the breast healing at different rates. I still have slightly drawn skin at the incision but have realised this will probably be the new normal. I hope radiotherapy goes well for you.


Thank you @mazz1066 … I was hoping that would be the case.

Hi SharonP

Thanks for posting.

It’s understandable that you worry about the breast changes you’re having during your treatment.

It’s early days following your surgery and healing of the wound is still taking place. Radiotherapy can also cause skin changes to occur whilst having the treatment and sometimes when radiotherapy has finished.

As @mazz1066 says, puckering of the scar can change over time, or this maybe how the scar will appear after healing has taken place.

However, it’s important to contact your breast care nurse or radiotherapy radiographers to check that the puckering is within normal limits. You are certainly not bothering anyone unnecessarily.
