Oral mucositis is a painful condition affecting the lining
(the mucosa) of the mouth and throat. It is a common side
effect of chemotherapy and radiation therapy.3
Although cancer treatments mainly attack cancer cells, some
healthy tissue, such as the mucosa, may also be damaged.
Nearly all patients who receive radiation therapy for cancer
of the head and neck and 50% or more of patients on
high-dose chemotherapy experience oral mucositis.3,4
Severe oral mucositis may prevent a person from eating
enough to maintain proper nutrition. As a result, cancer
treatment may be delayed or the drug dose may be reduced.3

If you are receiving
chemotherapy or radiation to the head and/or neck, you are
at risk for oral mucositis. People who smoke, drink alcohol,
don't practice daily oral care, wear braces or dentures that
don't fit well, and/or have dry mouth while receiving
chemotherapy or radiation are at greater risk for oral
mucositis.5,6
