Generally speaking, having cancer will cause one’s appetite to decrease, and cancer is a wasting disease that can increase the body’s metabolism. As the disease progresses, the treatment response and the patient’s mood swings will aggravate the loss of appetite, while the increasingly depressed immunity will also cause the patient to suffer from persistent high fever, bleeding and exudation, making the body consume more and more nutrients.
As a result, most malignant tumours are characterised by wasting, such as lung cancer, stomach cancer, liver cancer, oesophageal cancer, pancreatic cancer, colorectal cancer, leukaemia and malignant lymphoma.
