I agree 100% with Cynthia, my husband had radiation/chemo at the same time. They told him it upped the effects of radiation. He was stage 4 tonsil cancer, mets to 3 nodes, so they didn't give him an option. They did say Chemo alone for SSC isn't an option, they do it along with radiation. At least that is what this tumor board told us.
He did fine on it and he felt better knowing he was doing all he could for himself. He was on cisplatin, got sick for 2 days and tired...he didn't even lose his hair, just thinned a bit.
Good Luck in your decision.
