M&T Bank's president and chief operating officer, Mark Czarnecki, has been diagnosed with pancreatic cancer and plans to remain in his role at the bank while he gets treatment, the Buffalo News reported.

M&T spokesman Michael Zabel confirmed the report Wednesday.

Czarnecki, the No. 2 executive at the Buffalo, N.Y., company, said doctors told him the “prognosis for a complete recovery” is excellent, according to the report. Czarnecki has a small tumor, which doctors discovered early and began treatment immediately.

Czarnecki, who was 59 as of M&T's March 5 proxy, wrote to M&T's employees in an internal memo that he had “not been feeling well over the past few weeks” and underwent “various tests to understand the symptoms I was experiencing.”

He will undergo treatment at Memorial Sloan Kettering Cancer Center in New York and at Roswell Park Cancer Institute in Buffalo. The treatment will keep him from work “intermittently over the next few weeks and months,” but he said the treatment should finish by the end of the year.

Czarnecki has worked for the $97 billion-asset M&T since 1977, when he began his banking career. In addition to his president and COO titles, he is also chairman and chief executive of M&T's Wilmington Trust unit.

Michael Pinto, the former vice chairman of M&T, was diagnosed with cancer and resigned from the company in January 2014. He died later that year.
