Nutrition is a process in which food is taken in and used by the body for growth, to keep the body healthy, and to replace tissue. Good nutrition is important for good health. Eating the right kinds of foods before, during, and after cancer treatment can help the patient feel better and stay stronger. A healthy diet includes eating and drinking enough of the foods and liquids that have the important nutrients (vitamins, minerals, protein, carbohydrates, fat, and water) the body needs.
Incidence and Mortality
Estimated new cases and deaths from soft tissue sarcoma in the United States in 2013:
New cases: 11,410.
Soft tissue sarcomas are malignant tumors that arise in any of the mesodermal tissues of the extremities (50%), trunk and retroperitoneum (40%), or head and neck (10%). The reported international incidence rates range from 1.8 to 5 per 100,000 per year.

Nutrition therapy is used to help cancer patients get the nutrients they need to keep up their body weight and strength, keep body tissue healthy, and fight infection. Eating habits that are good for cancer patients can be very different from the usual healthy eating guidelines.
Healthy eating habits and good nutrition can help patients deal with the effects of cancer and its treatment. Some cancer treatments work better when the patient is well nourished and gets enough calories and protein in the diet. Patients who are well nourished may have a better prognosis (chance of recovery) and quality of life.
Cancer can change the way the body uses food.
Some tumors make chemicals that change the way the body uses certain nutrients. The body's use of protein, carbohydrates, and fat may be affected, especially by tumors of the stomach or intestines. A patient may seem to be eating enough, but the body may not be able to absorb all the nutrients from the food.
Cancer and cancer treatments may affect nutrition.
For many patients, the effects of cancer and cancer treatments make it hard to eat well. Cancer treatments that affect nutrition include:
Cancer and cancer treatments may affect taste, smell, appetite, and the ability to eat enough food or absorb the nutrients from food. This can cause malnutrition (a condition caused by a lack of key nutrients). Malnutrition can cause the patient to be weak, tired, and unable to fight infections or get through cancer treatment. Malnutrition may be made worse if the cancer grows or spreads. Eating too little protein and calories is a very common problem for cancer patients. Having enough protein and calories is important for healing, fighting infection, and having enough energy.
