Overview
Oral complications are common in patients receiving chemotherapy or undergoing radiation therapy to the head and neck.
The oral cavity is at high risk of side effects from chemotherapy and radiation therapy for a number of reasons.
- Chemotherapy and radiation therapy stop the growth of rapidly dividing cells, such as cancer cells. Since normal cells in the lining of the mouth also divide rapidly, anticancer treatment can prevent cells in the mouth from reproducing, making it difficult for oral tissue to repair itself.
- The mouth contains hundreds of different bacteria, some helpful and some harmful. Chemotherapy and radiation therapy can cause changes in the lining of the mouth and production of saliva and upset the healthy balance of bacteria. These changes may lead to mouth sores, infections, and tooth decay.
- Wear and tear occur from normal use of the mouth, teeth, and jaws, making healing more difficult.
Preventive measures may lessen the severity of oral complications.
Oral side effects may make it difficult for a patient to receive all of his or her cancer treatment. Sometimes treatment must be stopped. Preventing and controlling oral complications will enhance both the patient's quality of life and the effectiveness of cancer therapy.
Preventing and treating oral complications of cancer therapy involve identifying the patient at risk, starting preventive measures before cancer therapy begins, and treating complications as soon as they appear.
