Brazil soccer great Pele said on Monday that he was recovering in hospital from surgery to remove a tumour from his colon.
Pele, the only player to win three World Cups, did not say whether the tumour was malignant but the 80-year-old former Santos and New York Cosmos player said he is feeling good.
"Last Saturday I underwent surgery to remove a suspicious lesion in the right colon," he wrote in a social media post. "The tumour was identified during the tests I mentioned last week."
The Albert Einstein hospital in Sao Paulo said in a statement that they were keeping Pele in intensive care but expected to transfer him to a room on Tuesday.
The tumour has been sent for tests, it added.
"Luckily, I am used to celebrating big victories with you," Pele wrote. "I am facing up to this match with a smile on my face, a lot of optimism and happiness for being surrounded by the love of my family and friends."
The news came just hours after a Brazilian news outlet said Pele had spent six days in hospital after going in for his annual medical.
It also came days after Pele refuted reports he had fainted and 18 months after his son Edinho said his father was depressed, something the star quickly denied.
Pele was famous as a player for rarely getting injured but he has suffered from hip problems for years and cannot walk unaided.
His public appearances were already being cut before the COVID-19 pandemic and since then he has made few unnecessary forays outside his house near Santos.
