Abstract
Due to the high incidence of different types of cancer worldwide and mortality related to them, it is essential to know ways to prevent their complications that have a direct impact on the survival of the patient. 30 % of cancer deaths are associated with five behavioral and food risk factors. By deepening knowledge in this regard, we can avoid them.
Several studies affirm the vital importance of the nutritional status of cancer patients and their positive impact on the evolution of the disease. The early diagnosis and nutritional intervention assure multiple benefits, reduction of complications, faster recoveries, reduction of length of stay at hospitals, better tolerance to cancer treatments, among others. There are several tools to perform correct nutritional screening. In this article, we will describe the Nutritional Risk Screening 2002 and the Patient-Generated Subjective Global Assessment.
