Essential Insights on Advanced Stage Melanoma
Stage four melanoma is an advanced form of skin cancer that spreads to vital organs like the liver, brain, and bones. Early detection through self-exams and medical tests is crucial. Symptoms include skin changes, enlarged lymph nodes, and systemic signs depending on organ involvement. Treatment options such as immunotherapy and chemotherapy may help manage the disease. Recognizing the signs and seeking prompt medical attention can improve outcomes and survival rates. This article provides essential information on diagnosis, symptoms, and treatment strategies for advanced melanoma.

Stage four melanoma signifies the most progressed form of skin cancer, characterized by the spread beyond the skin to other organs such as lungs and liver.
Diagnosing Melanoma in Advanced Stages
Diagnosis involves several evaluations:
1. Blood tests assessing blood components and liver function
2. Imaging scans and ultrasounds to detect metastasis
3. A biopsy for definitive diagnosis
4. Consultations with oncology specialists to assess disease extent
Early Signs of Stage Four Melanoma
Changes in skin pigmentation or mole appearance are initial indicators. Nonetheless, these symptoms may not be present in all cases. Medical professionals often examine tumor location and check for spread to lymph nodes, which may feel hardened or swollen upon physical examination.
Tumor Size and Ulceration
In stage four, tumors tend to be thicker, typically around 4mm, though sizes vary among individuals. Treatment can reduce tumor size, but metastasis is still possible. Ulceration, or skin breakdown, may occur and signals an aggressive tumor. Patients with ulcerated tumors generally have lower survival rates, as noted by the American Cancer Society.
Self-Check for Skin Cancer
Regular self-examinations can help identify potential melanoma signs:
Color changes in moles
Asymmetry of shape
Changes in size over time
Size comparable to a pencil eraser
Irregular, uneven borders
How Melanoma Spreads
Stage three involves metastasis to nearby lymph nodes or surrounding skin, while stage four indicates spread to distant organs like the liver, brain, bones, or abdomen. Symptoms depend on the affected area—for example, headaches if the brain is involved or cough and breathing difficulties with lung metastasis. New or persistent pains after treatment should prompt medical consultation. Treatment options include radiotherapy, immunotherapy, chemotherapy, surgery, or targeted therapies.
