Benign, good-natured tumors are non-cancerous growths that generally cause no harm to the body. Unlike malignant tumors, benign tumors do not invade nearby tissue or spread to other parts of the body. Benign tumors are usually encapsulated, meaning they are surrounded by a membrane that helps keep them separate from other tissue. They can sometimes grow large enough to cause symptoms, however, and may need to be removed if they cause pain or interfere with organ function.
Types of Benign Tumors
There are many types of benign tumors, including lipomas, fibromas, adenomas, cysts, hemangiomas, and neurofibromas. Lipomas are fatty tumors that are typically soft and rubbery when touched. Fibromas are composed of fibrous tissue and are usually found on the skin. Adenomas are glandular tumors that usually originate in the thyroid, adrenal, or pituitary glands. Cysts are fluid-filled sacs that are often found on the skin and are usually harmless. Hemangiomas are composed of blood vessels and are common in newborns. Neurofibromas are composed of nerve tissue and are usually benign.
Treatment of Benign Tumors
Treatment of benign tumors is usually not necessary and may cause more harm than good. Many benign tumors will shrink or disappear on their own over time. However, if a tumor is causing pain or interfering with organ function, it may need to be surgically removed. Other treatment options may include radiation therapy, chemotherapy, or hormone therapy.
Preventing Benign Tumors
Since the exact cause of benign tumors is unknown, there is no sure way to prevent them. However, a healthy lifestyle may help lower the risk. Eating a balanced diet, exercising regularly, avoiding smoking and excessive alcohol, and getting regular check-ups can help reduce the risk of developing benign tumors.
