Understanding Cancer Mouth Sores

Mouth soreness (also called stomatitis and mucositis) occurs when the tissues lining the mouth or throat get thin due to treatment-related damage. Cancer mouth sores happen because treatments such as radiation and chemotherapy act to damage rapidly dividing cells and can’t distinguish between cancerous cells and other rapidly growing cells such as those lining your mouth and GI tract.

The importance of managing mouth sores

The mouth sores and ulcers of oral mucositis are reported as the single most painful and debilitating side effect of cancer treatment. Ulcerations can appear along the digestive tract including the lips, cheeks, throat, gums, and tongue, as well as the floor and roof of the mouth. Depending on their severity, mouth sores can result in added costs and unplanned hospitalizations.

Cancer mouth sores can lead to:

• Inability to eat, drink, swallow and speak
• Malnutrition and dehydration
• Weight loss
• Cancer treatment interruptions
• Emergency hospitalizations
• Tube feedings
• Use of opioid analgesics
• Reduced quality of life

More Than Just a Sore

For many patients, cancer mouth sores mean less time with family, loss of sleep due to pain, and overall reduced quality of life.
