Good morning, I had 15 treatments for mine cancer last September. 1 used Aquophour cream two times daily. It is a little greasy but I only had mild redness. It didn’t feel anything in the machine. It literally takes 10 minutes. I notice being a little more tire towards the end. A have an area under my arm that is a little darker and still a little redness under my breast. No pain. Remember it takes, I think about a year after radiation for all to heal. ( I think that’s what I was told. ) You got this. Remember you got this!! God bless and keep you.
