Whether it is better to have painful tumor or not, there is actually no good or bad difference. Because pain or not is not directly related to the danger degree of tumor, it mainly depends on the site of tumor occurrence. Generally, 70% of pain is directly caused by tumor, for example, tumor invading bones, nerve tissue, cavity viscera, or obstruction of duct system of parenchyma viscera, obstruction of blood vessels, causing mucosal ulcers to be involved will lead to pain. 10% of cancer pain is caused by malignant tumor syndrome, for example, pain caused by tumor with weakness, decubitus ulcer, rectal or bladder spasm, constipation and so on. Another 20% of pain is caused by the diagnosis and treatment process, including operation-related pain, acute postoperative pain, and postoperative syndrome. There are also non-painful cancer symptoms, such as painless hematuria. Hematuria with no abdominal pain is often an early symptom of kidney or bladder cancer, while hematuria with pain may be a urinary stone. Therefore, the difference between benign and malignant diseases, also with hematuria, depends mainly on the presence or absence of abdominal pain. There is also painless vaginal bleeding. If painless, contact bleeding occurs suddenly in middle-aged and elderly women, it may be a symptom of cervical cancer or uterine cancer. In addition, painless gastric ulcer, some elderly people do not have abdominal pain when suffering from gastric ulcer, but suddenly have black stool, which is found to have developed into gastric cancer after gastroscopy. Therefore, we cannot judge whether cancer pain is present or absent alone to determine whether it is good or bad. Therefore, we should mainly focus on the symptoms accompanying cancer pain, or the symptoms when there is no pain, and we should seek medical attention in time to avoid serious consequences.
