Cancer Treatment - Mucositis / Mouth Sores and Chemotherapy

What is mucositis?

Mucositis is the swelling, irritation, and ulceration of the mucosal cells that line the digestive tract. Mucositis can occur anywhere along the digestive tract from the mouth to the anus. It can be a very troublesome and painful side effect of chemotherapy. Anticipating mucositis may help to manage some of the symptoms.

What causes mucositis?

The cells that line the digestive tract are rapidly producing. In other words, the life span of these cells is very short compared to other cells in the body. Chemotherapy agents do not differentiate between healthy cells and cancer cells. Because the digestive tract cells reproduce rapidly, the chemotherapy agents can destroy them quickly, breaking down the protective linings, and leaving these linings prone to inflammation, irritation, and swelling. Mucositis can be even further complicated by nausea and vomiting that often occur with treatment.
