Nerve tumors can form in the peripheral nerve network anywhere in the body. These tumors often affect the function of the nerve, causing pain and disability. A large majority of peripheral nerve tumors are benign. Some are caused by neurofibromatosis, or schwannomatosis. Malignant Peripheral Nerve Sheath Tumors are very aggressive tumors and should be managed by a multi-disciplinary team.
There were 45,140 incident cases of cancer diagnosed among Singapore residents in 2003-2007. The incidence of cancer of the large bowel (colon and rectum) has ranked second for both males and females in Singapore since 1983 and in 2003-2007, and has overtaken lung cancer as the leading cause of cancer incidence among Singapore males. It accounts for 17.8% of cancers in males and 14.5% in females.
There are several factors in deciding to surgically remove these tumors. Some, like schwannomas are slow-growing and can be watched using imaging studies over time. Others, like malignant nerve sheath tumors need to be removed immediately, as they are very aggressive.
Mayo Clinic doctors have experience diagnosing and treating peripheral nerve tumors. Although peripheral nerve tumors are uncommon, Mayo Clinic doctors treat about 3,600 people each year for these tumors. Mayo Clinic doctors have been studying the peripheral nerve and its diseases for more than 40 years in the Peripheral Nerve Research Laboratory.
