What should you know about melanoma on a forearm?

Melanoma is a cancer arising from pigment-producing cells. On the forearm it may appear as a new mark or as a mole that develops irregular edges, several shades, a growing area, bleeding, crusting, itching, or tenderness. A spot that looks unlike the others on your skin also deserves attention.

These signs are not a diagnosis. Sun exposure, an injury, an inflamed mole, and other skin conditions can produce similar changes. A clinician may inspect the area with dermoscopy and recommend a biopsy. Tissue analysis identifies whether melanoma is present and provides information used to plan care.

Book a dermatology review without trying to remove or disguise the spot. Photograph it in good light and record changes, symptoms, and any recent injury. Protect the area from further sun exposure with clothing or sunscreen while arranging care, but do not let sun protection postpone an examination.

If testing confirms melanoma, the main local treatment is often removal with appropriate surrounding tissue. Your team may discuss Surgical Excision, Skin Cancer Surgery, or a Sentinel Lymph Node Biopsy depending on the pathology. More extensive disease may lead to discussion of Immunotherapy.

Arrange urgent review for a forearm lesion that is changing quickly, bleeding without a clear injury, becoming an open sore, or showing spreading redness, warmth, or discharge. Seek urgent medical help for new weakness, confusion, severe breathlessness, or a persistent severe headache. Those symptoms need assessment on their own and should not be explained away as a skin problem.

Ask how soon the spot should be biopsied, what the procedure will involve, and how the wound will be closed. Ask when pathology results are expected, whether the margins are clear, whether staging is indicated, and how often your skin and lymph nodes should be checked afterward.
