Crowd-sourcing radiotherapy advice

I used Dermaveen and whilst advised 3 times daily I used it more depending on need. I wore a Target front opening bra which became quite discoloured as you cream up for at least 3 months. Be wary of uv and wear a Rashie in the sun. I had 16 rounds of radiotherapy and was fine all the way thru but the week after it ended was enveloped by fatigue and slept a lot. I am very fair and was surprised my skin coped well.Be aware there can be longer term side effects rib pain , infection like cellulitis that can last for months after - get them checked to be reassured or a script though.
