A Washington man was cured of five brain tumors after doctors used a new radiation technique that specifically targets the masses without obliterating nearby cells.
Five years ago, Bob Searing, 70, of Burien, was diagnosed with prostate cancer and was treated with traditional radiation.
Last year, doctors discovered that - in an ultra-rare case - the cancer had spread to his brain. He was given just months to live.
But radiation oncologists at Kaiser Permanente in Seattle told Searing that they had advanced radiotherapy technology that could target Searing's tumors while preserving his healthy brain tissue - and in just a few hours.
After one round of treatment in July 2018 and months of follow-up scans, it was confirmed that the tumors have disappeared.

In May 2018, he called 911 and was rushed the hospital after experiencing blackouts and flashes at home
Searing told DailyMail.com that he happened to be in for a routine physical exam when he was diagnosed in fall 2014.
'I mentioned that I had urinary issues, having to go often, so my doctor decided to do a blood test,' he said.
Searing's doctor performed a PSA test, which measures the amount of prostate-specific antigen in the blood, and found that the levels were very high.
A follow-up biopsy at Kaiser Permanente confirmed that Searing had prostate cancer.
The American Cancer Society says prostate cancer is the most common cancer in US men aside from skin cancer.
In 2019, it is estimated that more than 174,600 men will be diagnosed with prostate cancer and more than 31,600 will die from the disease.
Prostate cancer typically grows slowly and, if detected early while it's still confined to the prostate gland, there is a successful chance of treatment.
