How can melanoma be recognized?
Melanoma is a type of skin cancer arising from pigment-producing melanocytes that can spread if not recognized early. Symptoms vary and overlap other conditions, so internet information alone should not be used for diagnosis.
Features, causes and evaluation
1. Features, causes and risks A new or changing mole may show asymmetry, irregular borders, multiple colors, growth, itching or bleeding. Not every melanoma has all classic features, and some lack pigment. A risk factor does not guarantee disease, and its absence does not exclude disease. Onset, duration, triggers, medicines and coexisting conditions change the assessment. 2. Clinical evaluation A health professional starts with history and examination and selects laboratory or imaging tests according to the likely possibilities. One out-of-range result does not always prove disease, and a normal result may not exclude every possibility. Age, pregnancy, medicines and clinical context matter.
Follow-up, prevention and when to seek help
1. Follow-up, prevention and safety Self-examination can help notice change but does not diagnose melanoma. A suspicious lesion is assessed with dermatologic examination, dermoscopy and biopsy when needed; a rapidly changing or bleeding lesion should be evaluated promptly. Treatment depends on diagnosis, severity, other conditions, pregnancy, medicines and personal preferences. Starting, stopping or changing a prescription without professional advice can be unsafe. 2. When to seek help Seek care for new, persistent, worsening or function-limiting symptoms. Sudden breathlessness, chest pain, fainting, new weakness or speech difficulty, uncontrolled bleeding, severe dehydration, confusion or risk of self-harm requires emergency help. This is general information and not a personal medical assessment.
