University Provost Harvey V. Fineberg '67 is undergoing surgery this week for what appears to be an early stage of prostate cancer, Harvard officials said last night.

Associate Provost Dennis F. Thompson will coordinate the provost's office during what Fineberg expects to be about a month-long absence from his post.

"The prognosis is good," said Joe Wrinn, the University spokesperson.

Fineberg notified his staff of the situation Tuesday and told deans and other University officials yesterday.

"He and his doctors are optimistic," Thompson said yesterday. "Harvey was able to get most of the critical business under control before he left this afternoon.... So far everybody seems to think business is in order and we'll be able to manage for a while."

According to a statement released by the Harvard News Office, Fineberg expects to resume his tasks gradually over the next few months.

"The work of the office is continuing in exactly the same way in his absence," Assistant Provost Sarah Wald said.

Assistant Provost Marsha Semuels said she does not expect Fineberg to be gone for very long.
