Patients with early-stage melanoma generally experience symptoms such as moles rapidly growing larger, changing in shape and color. Slightly more severe cases may exhibit signs like itching and bleeding. If the melanoma progresses, it might lead to non-healing ulcerations, repeated occurrences of satellite lesions, regional lymph node metastasis, and migratory metastasis. In advanced stages, patients may experience bone metastasis pain. Lung cancer metastasis might manifest as coughing and coughing up blood, and symptoms can vary depending on the site of metastasis.
