Good catch Iser!
Definitely ask about and discuss the risks of their recommended treatment plan and other treatment options too.They'll touch on it, they have to have you fully informed by law to go ahead, so if anything is unclear at all don't be afraid to chase it down. I was like a dog with a bone when they mentioned the "chance of giving you Leukemia" so casually it were as if they were telling me there'd be tomato in my salad. Yipes.
You have options, what they recommend isn't the last say, you can explore those.
