Skin changes after radiotherapy

Good Morning everyone

I was wondering if anyone’s experienced skin changes to breast following radiotherapy? Iv noticed skin tags and I think new moles. I was diagnosed Nov 22 with TNBC stage 1 no lymph nodes affected.
Iv heard people say they’ve gone on to have skin cancer after treatment for TNBC… I’m really concerned… Iv had some moles checked by the GP but still I’m worrying.

Thank uoi for reading xx

I’m 18months post radiotherapy and have some skin changes to my breast and also change in shape too
The breast has become darker in colour but recently I’ve developed a rash under my skin (looks like small heat lumps and itchy )
I’ve had a biopsy and it’s come back positive for cells so waiting for a date to have elecrochemotherapy which has good success rates apparently :pray:
It’s important to ask your team if you have any concerns as we all know our own body and can’t always rely on stats
I’m sending best wishes to you xx

Hello sammij1980,

Thanks for posting. It’s understandable to feel concerned after noticing some skin changes in the area treated with radiotherapy. Skin changes can also develop as we get older. It’s good to see you have seen your GP about these.

Skin reactions are common with radiotherapy. As you say you have darkening of the skin. Some reactions are short term some in the longer term. You can read more detailed information here. And you can find out about others experiences here.

Both radiotherapy and chemotherapy can an increase the risk of another cancer however this is very rare and the benefits of treatment outweigh this risk.
