Q: How is radiation therapy used to fight head and neck cancers?

Radiation damages the DNA in cancer cells and inhibits their ability to reproduce. When the damaged cancer cells attempt to divide and multiply, they die, which helps to stop the tumor growth. In some cases, the tumor may shrink. Normal cells, however, can usually recover from radiation damage more easily. You and your treatment team will discuss your options and what type of radiation might be appropriate for your particular case.
