I am very fair and had 3 weeks of radiotherapy.My skin held up well as I creamed up frequently with Calendula cream at the radiotherapy centre and followed up with Dermaveen.Many ladies on here are keen on MooGoo.You need to cream up at least 3 times per day for up to 3 months so a front opening post op bra like Target sell is handy.
I’m not sure where you are but be wary of UV as it seems to activate the irritation as does heat. I went to Cairns shortly after treatment ended and found even a rashie wasn’t enough so needed to be careful.
The first planning session is the longest around 45 minutes thereafter it’s a daily zapping of around 15 minutes with the worst bit for me being trying to find a park in the city - allow plenty of time to get there.
Be also aware at the end of treatment you will probably be engulfed with fatigue for a few days so plan to take things easy and go with the flow of your body.
