In a very simplistic way, the human body has an extremely complex system of cell division that determines the growth of new cells and the death of senescent cells. However, the organism is not perfect and sometimes fails. In the course of the interaction between genetic and environmental factors, including nutritional factors, oncological disease can arise. Of course, no food alone has properties capable of preventing a tumor. In recent years there has been an increase in the number of new cases of cancer. Malnutrition in cancer patients is a consequence of the increase in inflammatory cytokines associated with cancer, metabolic alterations and concomitant inadequate availability of nutrients, due to anorexia caused by the disease and systemic treatments. Malnutrition, combined with loss of muscle mass, is very common in this group of patients and has a negative effect on the prognosis. What to expect from the doctor? It is one of the key questions in this theme.
从非常简单的角度来看，人体拥有一个极其复杂的细胞分裂系统，这个系统决定了新细胞的生长和衰老细胞的死亡。然而，人体并非十全十美，有时也会出错。在基因和环境因素（包括营养因素）相互作用的过程中，可能会出现肿瘤。当然，没有任何一种食物具有预防肿瘤的特性。近年来，癌症新发病例的数量有所增加。癌症患者的营养不良是与癌症相关的炎症细胞因子增加、代谢改变以及由于疾病和全身治疗引起的厌食导致的营养物质供应不足的结果。由于这种疾病导致的肌肉质量丧失，营养不良在这组患者中非常常见，并对预后产生负面影响。患者应该从医生那里得到什么？这是这个主题中的关键问题之一。
