Scaly skin just below nipple

It is a year ago since I finished radiotherapy after being diagnosed with high grade DCIS & I had the all clear from my first mammogram in November but yesterday I noticed the skin just below my nipple felt a bit rougher. When I looked it doesn’t seem to be a different colour but scaly. When I lifted the breast to get a better picture it seems to be on the bottom of my nipple as well. Common sense tells me it has been there longer than I think & is just the after effects of radiotherapy so trying not to think to much into it but wondered if anyone else had anything like this.

Hi - it is very probably nothing -maybe a bit of execma ,but if it doesn’t clear up in a week or so may be worth getting it looked at / getting some advice from breast nurse. ??
