David Hess announced on Twitter this weekend that he had been "cured" and cleared for activity, just three months after being diagnosed with a cancerous tumor in his chest.
Hess, 28, went to the emergency room last October after experiencing chest tightness and shortness of breath. Subsequent testing revealed that he had a cancerous germ cell tumor that was "pressing majorly" against his heart and lungs.
The Tampa Bay Rays right-hander began to receive chemotherapy treatment shortly thereafter.
Hess has appeared in 62 games over four Major League seasons with three different teams: the Rays, Baltimore Orioles and Miami Marlins.
