Perianal tumors can show up as lumps near the anus and may cause symptoms like bleeding, pain, or changes in the skin. Treatment depends on whether the tumor is benign, premalignant, or malignant and might include surgery, radiation, or other therapies.
A perianal tumor is a growth that forms in the skin around the anus. Sometimes, you might notice a lump that may be firm or change in shape, and there may be symptoms like pain, bleeding, itching, or changes in the skin's color and texture. In some cases, these tumors do not cause symptoms at first and are found during a routine exam. There are benign tumors that do not grow or spread, and there are premalignant or malignant tumors which can be more serious. The treatment options vary based on what type of tumor is present. For benign or premalignant tumors, doctors might choose to remove the lump with minor surgery. If the tumor is malignant, more specialized treatments could be needed, such as more extensive surgical removal, radiation therapy, or even chemotherapy. The choice of treatment depends on the size, type, and location of the tumor, as well as your overall health. If you notice any unusual changes near the anus, it is important to see a healthcare provider to get a full evaluation and the right treatment plan.
