    Many people who suffer from cancer experience changes in their appetite and their weight.

Having cancer, can change the body's metabolism - the process in which your body digests and breaks down sources of energy. As a result, your appetite can decrease and/or you can lose weight.

    Weight loss and decreased appetite that are not caused by chemo- or radiation therapy but by the cancer itself, are more often seen in people with advanced or spread disease.
