JUNEAU -- Kenai legislator Tom Wagoner is being treated for prostate cancer in California.

The Senate Republican left Wednesday for Loma Linda University Medical Center in California. He attended Tuesday's opening ceremonies, where he was sworn in for a third term.

He is expected to return to Juneau on Feb. 16.

Wagoner is undergoing proton therapy, which is described on the center's Web site as a precise form of radiation treatment that minimizes damage to healthy tissue and surrounding organs.

According to the Web site, the treatment is highly successful and results in fewer side effects.

Wagoner said the cancer has not spread beyond the prostate, and his doctor has said his chances of full recovery are excellent.

Wagoner started treatment Dec. 1.
