Saturday morning I woke up with a rash on my hand and nose and a red itchy lump on my neck right around where the lymphoma was. My last radiation treatment was October 31. I am really scared that the cancer has come back. Right now the dr is treating topically (if that is the right word) with ointment and benadryl. Could the cancer have come back this quickly?/ Has anyone experienced this? I truly am scared.
