SAN FRANCISCO—Governor Jerry Brown will undergo further radiation treatment for prostate cancer in San Francisco, his office announced on Saturday, January 28.

Brown, 78, will be treated by Dr. Eric Small, an oncologist at the University of California, San Francisco Medical Center.

“Fortunately this is not extensive disease, can be readily treated with a short course of radiotherapy, and there are not expected to be any significant side effects. The prognosis for Governor Brown is excellent,” said Dr. Small in a statement.

He will continue to work a full schedule during his treatment that is expected to take place between late February and early March, his office indicated.

Brown first disclosed his battle with cancer in January 2012 after he received his first treatment for an early stage of prostate cancer. He maintained a full work schedule during the four-week treatment with Dr. Small.

In April 2011, Governor Brown underwent a minor surgery to remove a cancerous growth on his nose. He was put under local anesthetics and surgeons removed a form of skin cancer called basal cell carcinoma, a common illness people get as they age, from the right side of his nose.

He has dedicated his career to politics, and has served as the secretary of state, attorney general and the Mayor of Oakland. He will reach the end of his term as governor in 2018. Brown has not announced any plans to run for any other political offices.
