Final answer:
Metastatic melanoma has a 17 percent 5-year survival rate, which is significantly lower than the rate for thinner melanomas with a thickness of less than 0.75mm. Melanomas are identified by large, uneven brown or black patches on the skin.
Step-by-step explanation:
The question concerns the survival rate of patients with metastatic melanoma compared to those with melanoma that has a thickness of less than 0.75mm. Metastatic melanoma has a significantly lower 5-year survival rate because it has spread to other organs, with only about a 17 percent chance of survival for five years after diagnosis. On the other hand, thinner melanomas, specifically those with a thickness of less than 0.75mm, tend to have a much higher chance of survival, though the exact 5-year survival rate is not provided in the available information.
Melanomas typically present as large brown or black patches with uneven borders and a raised surface, so keeping an eye out for changes in skin lesions—including an increase in diameter or evolving shape—is critical for early detection and treatment.
The 5-year survival rate for metastatic melanoma is typically lower than a 5-year survival rate for melanomas with a thickness of less than 0.75mm. According to the given information, there is only a 17 percent chance of patients surviving for five years when the melanoma has spread to other organs. However, the specific survival rates for each category would require further information.
