BOISE, Idaho -

Former Idaho Gov. Cecil Andrus says doctors removed part of his right lung earlier this month after finding a malignant tumor.

Andrus tells the Idaho Statesman that doctors found no sign of any other cancer after the five-hour surgery on July 3 and there are no plans for chemotherapy or radiation.

The 83-year-old Andrus is Idaho's longest-serving governor, holding office from 1971 to 1977, and 1987 to 1995.

Andrus is recuperating at home and says he plans to go on his annual elk hunt in October.
