California Governor Jerry Brown is undergoing medical treatment for "localized prostate cancer," the governor's office announced on Wednesday.
The governor's office said Gov. Brown is working a full schedule, reports the Sacramento Bee.
Eric Small, Brown's oncologist at University of California San Francisco, said in a statement: "Fortunately, this is early stage localized prostate cancer, which is being treated with a short course of conventional radiotherapy. The prognosis is excellent, and there are not expected to be any significant side effects."
Gov. Brown's office said the treatment is expected to be completed the week of Jan. 7. He had a previous procedure in April 2011 to remove skin cancer from his nose.
