All patients with Stage III melanoma should have a physical examination, including LDH testing, skin examination, chest x-rays, CT scans of trunk, pelvis and head every 3 months for the first year, every 4 months for the second year, every 6 months for years 3-5, and annually after 5 years.

With treatment, Stage III melanoma is considered intermediate- to high-risk for local recurrence or distant metastasis. Therefore, early detection of melanoma through skin self- examination and medical examination continues to be of utmost importance.
