Brazilian football great Pele was discharged from hospital Thursday after two weeks of chemotherapy for a colon tumor, announced the Sao Paulo hospital that treated him.

The 81-year-old ex-player known as "O Rei" (The King) "is stable and will continue the treatment of the colon tumor that was identified in September of this year," the Albert Einstein Hospital said in a statement.

It is the latest in a string of health troubles for the aging star, whose public appearances have grown increasingly rare.

Considered by many the greatest footballer of all time, Edson Arantes do Nascimento -- Pele's real name -- is the only player in history to win three World Cups (1958, 1962 and 1970).

He burst onto the global stage at just 17 by scoring dazzling goals, including two in the final against hosts Sweden, as Brazil won the World Cup for the first time in 1958.

He went on to have one of the most storied careers in sport, scoring more than 1,000 goals before retiring in 1977.

Pele announced on Instagram on December 9 that he would stay in hospital for just "a few days" for chemotherapy.

"Don't worry, I'm just getting ready for the holiday season!" he said in a message to fans.
