And she's "sort of" right. Radiation IS used for "curing" a number of things, including cancer. Even non-medical application of radiation could kill cancers too.
I think of it like going after a herd of animals with guns. You start shooting, they start running. Only the weakest, oldest and sickest will make easy targets ... so you kill them all. That "strengthens" the herd now because they're rid of all their defectives.
At the same time, you kill or maim a number of healthy animals too. Maybe most of those will die as well but ... there's a chance that some will survive and create a NEW "burden" on the herd because of their disabilities brought about by their wounds.
That's radiation for you. It kills cells -weakest ones first (ie cancer cells). At the same time, it kills healthy cells and mutates some of them ... leading to later cancer development when these cells reproduce.
Radioactive Iodine is most feared now from the Fukishima reactors. But ... doctors USE this isotope to KILL hyperactive thyroids too!
Doctors' reasoning is that just a little bit of radioactive iodine is bad because it will lead to cancer of the thyroid. But if a HEAVY does is administered, it totally kills the thyroid gland so that there will be no cells left to mutate into cancerous cells later.
