What is the life expectancy in years for stage 4 melanoma?

Stage 4 melanoma, also known as metastatic melanoma, typically has a lower life expectancy compared to earlier stages due to the cancer spreading to other parts of the body. The median survival rate for stage 4 melanoma can vary widely, but it is often around 6 to 12 months, with some patients living longer due to advancements in targeted therapies and immunotherapy. Individual prognosis can depend on various factors, including the patient's overall health, response to treatment, and specific characteristics of the tumor. Always consult a healthcare professional for personalized information.
