Malignant tumors may be painful when pressed. If it is an early stage of malignant tumor, it usually does not hurt when pressed, but as the tumor develops, the tumor cells themselves will produce abnormal nerves, and these nerves may cause pain. The tumor may also compress the surrounding normal tissues and organs as well as nerves, which may also lead to pain. If pain occurs, whether the tumor is in early or late stage, analgesic treatment is needed. In addition to conventional analgesic treatment, active anti-tumor treatment is needed according to the specific clinical stage, as long as the tumor is removed or shrunken, the patient’s pain will naturally be reduced or even disappeared.
