Mucositis During mucositis the mucous membranes become reddened, swollen, and painful. Open sores called ulcers or lesions can develop. Mucositis is caused by the effect of chemotherapy and/or radiation therapy on the cells that make up the mucous membranes. Radiation therapy only causes mucositis of the mucous membranes in the area(s) being treated. However, since chemotherapy is usually given in a way that it travels throughout all areas of the body, it can affect the mucous membranes throughout the body. Mucositis can cause mild or very serious changes. It may only cause a change in feeling in the mouth. For other people it may cause redness and sores in the mouth. More severe mucositis involves many sores in the mouth, bleeding, and severe pain. When mucositis is severe, it can cause other problems including difficulty swallowing, talking and eating as well as very severe infections. Thus it is important to remember there are things you can do to make a difference. You may find it helpful to talk to others who have experienced this side effect, but always remember every person is different. You may or may not have the same experience as another person. |
