Nutritional status and cancer

Cancer, the treatments that accompany it and the symptoms that in turn generate, increase the risk of suffering energy-protein malnutrition in patients with this disease, which causes a great deteriotation of health status, increased complications, decreased tolerance of cancer treatment and the patient’s quality of life. Among the prognostic factors such as the type of tumor, the stage of the disease and the general condition of the patient, involuntary weight loss is the potentially most sensitive factor to therapeutic intervention. All this leads to the inclusión of an nutritional intervention as a therapeutic tool involved in cancer treatment.
