@mg2 I had a lumpectomy in December 2017 & started radiation treatment in Feb/March the following year. The main reason it was that late is that I had to have genetic testing done beforehand & my rad onc wanted the results before he started the rad treatment as if I came back positive, it may have effected my treatment plan & whether I was to go ahead with it or not. Luckily, I was negative so the treatment went ahead as planned.
As mentioned above by others, I used Mepitel film through the course of my treatment & cant speak highly enough of it. I had NO redness, irritation, peeling or burning & would recommend it to anyone who is able to have it. One of the many benefits is when you use it, you dont have to use ANY creams with it as the mepitel film covers your entire radiation area. Once i removed the film, 3 weeks after treatment, I used calendula cream just to soothe it as it had been wrapped up for 5 weeks, not because I was burnt. Good luck with your treatment xx
