McDonald’s new chief executive Charlie Bell, who underwent cancer surgery about two weeks after he was promoted to CEO, has said his illness has not interfered with the company’s operations.

Bell, who had surgery for colorectal cancer, has said he will be undergoing a course of chemotherapy, which he will receive twice a month for about six months, but does not anticipate any major changes to his schedule, reported Reuters.

“I’m feeling good and I’m looking forward to a complete recovery,” Bell was quoted by Reuters as saying. “My time out of the office has not interfered with the running of our restaurants.”

Bell said the company has no immediate plans to appoint a new chief operating officer to fill the position vacated by Bell in April following the death of then-CEO Jim Cantalupo.

“Succession planning is something we take very seriously,” Bell said.
