One of the most effective treatments in the battle against cancer is radiation therapy. The whole premise is that a machine makes high energy waves that destroy cancer cells. It can be used in a wide variety of cancer including head and neck, breast, prostate and colon to name a few.

The problem is that radiation can destroy cancer cells but harm healthy ones as well. This can lead to side effects. The side effects last only a short time and will go away after treatments are done.
The most common side effects are depression, fatigue, nausea, vomiting and diarrhea.

Of course, the benefit — or hopeful result — is allowing the body and its healthy cells to overcome the cancer cells and win the battle.
