A person with mouth cancer may suffer from anorexia, or loss of appetite. Anorexia may be caused by cancer, because cancer can affect the body's hormones, digestive system and brain. It is also a common side effect of chemotherapy and radiation therapy.

Good nutrition is an important part of successful cancer treatment. Adequate nutrition can boost the immune system and help increase the effectiveness of cancer therapy.

Home care for anorexia includes:

• Avoid stomach irritants such as aspirin or ibuprofen.
• Avoid excessive caffeine and other stimulants.
• Check with your doctor about drinking alcohol.
• Do not force yourself to eat at standard times. Eat when you are hungry instead.
• Concentrate on eating a healthy diet. Avoid junk foods.
• Select healthy, high-calorie foods that you enjoy.
• Eat more frequent, smaller meals.
