I am looking at my proof right now - my son.I am not "splitting hairs" here. You claim (with no evidence) chemo and radiation cure cancers. I say they do not. Find some evidence chemo or radiation cure cancers. You wont because there isn't any. It takes a combination of many things to cure cancer and chemo and radiation are among the least likely to cure.Yes it can come back. That really does not change anything.Doctors treat cancer with the hope it will go into full remission. They cannot expect anything more than that. Have you ever heard of a doctor say, "Hey, we're going to cure your cancer with chemo/radiation."? No, you haven't. They say they will "treat" the patient with chemo and/or radiation.Yes they are and yes they do.Chemo and radiations are "treatments". Treatments are not meant to cure, nor do they.The positives are quite obvious - the vast majority of people with forms of cancer that can be treated with chemotherapy will die.
Moest who are treated do not or at least have significantly higher survival rates. Chemo is brutal and very sad but saves lives. The treatments have been thoroughly tested over decades and newer treatments are coming out every year.
I have no idea what you seem to think treatments are supposed to do then.

You are splitting hairs here. They cannot fully tell if the cancer is totally cured or not but it certainly does cure many patients. All will continue monitoring in case it does come back from some cells missed.
