Hi, Mary
Being a bit concerned about what Dr L told you about "necrosis" and tumor death, I just googled "necrosis & radiation" and came up with some interesting stuff, like this definition:
radiation necrosis (RAY-dee-AY-shun neh-KROH-sis) - The death of healthy tissue caused by radiation therapy. Radiation necrosis is a side effect of radiation therapy given to kill cancer cells, and can occur after cancer treatment has ended.
From what you say he said to you, do you think this is what he meant? I.e., not the death of the tumor itself, but a possible side effect (like a new disease affecting different or healthy tissue) that results from the radiation. There were also several articles on this possible side effect!
So, he and you were thinking about two different things, hopefully??!! Because I like his answer if he said no to the necrosis of healthy tissue as a side effect of the radiation!
Amazing the info you find online!
