Mickey Mantle was 63 years old when he died of liver cancer on August 13, 1995.

Mantle had received a liver transplant in June of 1995, as treatment for advanced liver disease likely caused by long-term, chronic alcohol consumption.

After the transplant, though, doctors soon discovered cancer in Mantle’s lungs and in other parts of his body, and they subsequently revealed those to be liver cancer that had metastasized and spread.

Mantle made a heartfelt plea to kids to “not be like me.”
