I am an x-ray tech, not a doc but i do know a few things about radiation. Radiation can cause hair loss, but not always. Good news, it grows back thicker. Radiation alone can cure some cancers but not all. Depends on what kind.Does radiation cause hair loss , or is that just chemo ?
A greater dose of radiation always cause hair loss, but its just temporary~ It'll grow back again. You can kill cancer with just radiation, depends on where is it located and what type of cancer it is. For your lumps maybe you would like to talk to your doctor if you're worried about them. And I'm a student X-ray tech.
I'd say Radiation fries all the good and bad cells in ones body..And yes I'd also say that it can make you loose your hair, it don't always make people sick but it will make you feel tired I'd assume.. GOOD LUCK try not to worry, easier said than done i'm sure..
