Why do cancer patients feel pain

1. The cause of the cancer itself
        Cancer patients will suffer from pain, in most cases because of the cancer itself. As the disease progresses, the size of the tumor will become larger and larger, and it will gradually compress the surrounding tissues and organs, and a painful sensation will appear.

2. Causes of cancer metastasis
        If the cancer is detected late, after the cancer cells have metastasized in the advanced stage of the cancer, they will also experience pain because they have metastasized to the organs. For example, if there is bone transfer, the bones will feel very painful, especially the joint pain is even more unbearable.

3. The influence of chemotherapy and other treatment methods
        Cancer treatment is different from the treatment of ordinary diseases, especially chemotherapy, which is a challenge to the body and mind of cancer patients. There are some treatment methods that will inevitably cause some damage to the patient's body, and the pain of the wound is also the source of pain for cancer patients.
