Hotel chain Marriott International said on Friday CEO Arne Sorenson was diagnosed with phase 2 cancer, but will continue in his role while being treated.
Sorenson will start treatment, starting with chemotherapy next week, and surgery is expected by the end of 2019, the company said.
The cancer was discovered early and does not appear to have spread, said Sorenson in the message to employees.
Sorenson, who joined Marriott in 1996, has since held a number of positions as well as bringing in nearly $ 14 billion in the acquisition of Starwood Hotels & Resorts Worldwide in 201
In March, Sorenson apologized for a US Senate panel for a massive data breach of up to 383 million guests in its Starwood hotel reservation system and pledged to protect against future attacks.
Marriott is scheduled to announce first quarter results next week.
