Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a clinical skin examination, followed by a biopsy of the suspicious lesion to identify cancer cells. Imaging tests such as ultrasound, CT scan, or MRI might be used to assess the extent of the disease and check for spread to lymph nodes or other organs. A complete medical history and physical examination are vital components of the diagnostic process.
Treatment Protocols: Treatment options typically include surgical removal of the tumor with clear margins to excise the cancerous tissue. Sentinal lymph node biopsy may be performed to check for spread. Depending on the tumor's size and spread, additional therapies like radiation therapy or immunotherapy could be recommended.
