Tailbone tumors are tumors that occur in the sacrococcygeal region. Early common symptoms include pain, lump, numbness caused by nerve damage, incontinence and so on. Pain is a common symptom of tumor, benign tumors can cause pain because of pressing surrounding tissues, malignant tumors can cause pain because tumor cells erode nerves, bone and so on. Lumps, benign tumors are mostly spherical, with clear boundary, smooth texture, soft and slow growth, no pressure and pain, and generally no systemic symptoms. The mass of malignant tumor has unclear boundary, rough and hard texture, pressure pain, and may be accompanied by body wasting.
