When does cancer start to hurt?

Cancer usually begins in the middle and late stages of pain.

Cancer refers to malignant tumors. In the early stage of the disease, the tumor size is small, and the tumor cells do not invade the surrounding areas, so there will be no obvious pain. With the development of the disease, the tumor cells continue to proliferate and differentiate, which can invade the peripheral nerve endings and cause pain. At this time, the disease usually has entered the middle stage. In the late stage of cancer, the tumor has metastasized and formed new metastases. At this time, the tumor cells can continue to invade the nerve endings around the metastases, causing pain.

Cancer is a consumable disease. Patients should supplement foods with high protein and high vitamins in their daily life to enhance their physique and improve their resistance to disease.
