ELi5: What does medical radiation do to the body?

1.01K viewsBiologyOther

I have breast cancer and I’m starting radiation tomorrow. I understand that it’s supposed to reduce the risk of reoccurrence and that it is destroying cells. But how? Which cells are affected? Why will it make me tired?

If you’re doing radiation / chemo you will be tired. Your body is working to heal itself and needs the energy. Most importantly though is giving your body the fuel it needs.

You’re going to be nauseous / nauseated. Eat as much calorie dense foods as possible. Find foods that your stomach will tolerate. Don’t make yourself worse, just eat as much as you’re able. Your body needs that energy to keep fighting. If your body is calorie deficient it can’t fight.

Best wishes on your recovery.
