What should you know about stage ia melanoma?

The stage combines the tumour’s measured thickness and features seen under the microscope with the absence of known spread. Ulceration and other pathology details may affect the exact staging discussion. Stage IA is not the same as a suspicious mole that has never been biopsied; it refers to melanoma confirmed in tissue. A clinician will also check nearby skin and lymph nodes, because staging depends on the complete clinical picture.

The [Melanoma](/conditions/melanoma/) page gives broader background on this skin cancer.

If the first biopsy did not remove enough surrounding tissue, a wider [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/) may be recommended to clear the edges. The procedure and scar depend on the site and size. A sentinel lymph node procedure is not automatically needed for every stage IA case; ask why it is or is not being considered for your pathology. Protect the healing wound as instructed, then learn how to check your skin, scalp, nails, and lymph-node areas.

After surgery, contact the clinic for increasing redness, swelling, discharge, wound separation, fever, or pain that is not settling. Later, arrange a review for a new or changing mole, a sore that does not heal, a firm lump near the scar, or a persistent swollen lymph node. These findings do not prove recurrence, but they should be examined rather than watched indefinitely. Urgent help is needed for heavy bleeding or rapidly worsening illness.

What are the measured thickness and microscope findings? Were the margins clear, or is more [Skin Cancer Surgery](/treatments/surgical-dermatology/skin-cancer-surgery/) needed? How should I care for the scar? Do I need a [Sentinel Lymph Node Biopsy](/treatments/diagnostics-and-staging/sentinel-lymph-node-biopsy/)? How often should my skin and lymph nodes be checked, and what should prompt an earlier visit?
