When you have radiation treatment for cancer, your body goes through some changes.
Two weeks after radiation treatment starts, you might have changes in your skin. Your skin and mouth may turn red, your skin might start to peel or get dark, or your skin may itch. Also your skin under your chin may get droopy. Most of these changes will go away.
You may also have dry mouth, mouth pain, nausea, or it may be hard to swallow. You may lose your sense of taste, and you may not be interested in eating.
Your jaw may feel stiff, and it may be harder to open your mouth very wide. Your dentures may no longer fit well, and they may cause sores in your mouth.
Your body hair will fall out 2 -o 3 weeks after radiation treatment starts, but ONLY in the area being treated. When your hair grows back, it may be different than before.
