What should you know about pale melanoma?

Melanoma is a skin cancer that may be brown or black, but some lesions are pink, red, pale, or mixed in colour. An uneven border, asymmetry, growth, new symptoms, bleeding, crusting, or a sore that does not heal can be concerning. Appearance alone cannot confirm or exclude melanoma; examination and tissue testing provide the diagnosis. Melanoma can begin in an existing mole or appear as a new lesion.

Arrange a prompt skin examination and avoid repeatedly picking, scraping, or treating the lesion with cosmetic products. Photograph it beside a ruler if this does not delay care, and note when you first noticed the change. If melanoma is suspected, a clinician may recommend Surgical Excision or Skin Cancer Surgery; staging may include a Sentinel Lymph Node Biopsy. Treatment choices depend on the examination and pathology.

Seek prompt medical review for a new or changing pale spot, especially if it grows, bleeds, crusts, becomes tender, or develops several colours. Do not wait for dark pigment to appear. Urgent care is appropriate for uncontrolled bleeding, severe pain, rapidly worsening swelling, or new neurological symptoms in someone already diagnosed with melanoma.

What features make this lesion concerning? Is a biopsy or Surgical Excision needed? If melanoma is confirmed, what staging information is available? Would Immunotherapy or Follow-Up After Cancer Treatment be relevant to my situation?
