It was 3 years ago I had radiation for 30 days on the right side of chest + 3 days concentrated on area of tumor. (Boost?). I was advised to moisturize immediately after treatment (a.m.) plus 3 more times each day. I used Udderly Smooth (available on Amazon, farm supply stores and various other retailers). I preferred it because 1). It's inexpensive
2). It is a little more watery? than most creams or lotions so there is less friction on the damaged skin when applying and absorbs easier. 3). It was recommended not only by the radiation team, but also by one of my infusion nurses. I had zero problems with skin damage after 33 treatments. The skin in that area was a smidge darker, but you had to really look. The only issue I had was as it was summer, and you know about sweat under the breast, one day I was a little too aggressive with a washcloth and irritated the skin there. After a few days of a little TLC, it healed on its own, and i learned my lesson. I did not have a body mold, and only two tattooed dots. To this day I use Udderly Smooth as a body lotion.
