Blue light makes bladder cancer glow pink

This year, more than 82,000 people will be told they have bladder cancer, and almost 17,000 will die from it. Now, new technology is helping to light up the problem like never before.

Frank Sinatra had it, and so did Jack Lemmon, Telly Savalas, and U.S. Sen. Hubert Humphrey. Bladder cancer is almost three times more common in men than women. The key to beating it: early detection.

One of the first signs is blood in the urine. Also, patients may have to urinate frequently and experience pelvic or back pain. Detecting bladder cancer early is key to survival.

“It’s very important because when we find this, people on this stage, we can offer them the treatment, aggressive treatment,” explained Dr. Amirali Salmasi, a urologist at UC San Diego Health.

Oncologists at UC San Diego are now using blue light cystoscopy to detect and monitor bladder cancer. It’s the same technology used in computer monitors, smartphones, tablets and TVs.

Before the procedure, urologists insert a special dye into the bladder. Then, using a catheter, doctors use a camera with a white light to look inside. Then, they switch to a blue light. Combined with the dye, it makes the once undetectable cancer cells glow fluorescent pink.

“With blue light, the cancer cells accumulate these drugs and they fluoresce. By doing that, we can have some contrast between the tumor cells and the normal cells,” Salmasi said. “And by doing that increase our detection rate. In 11% of the people, they can change your diagnosis or upgrade your diagnosis.”

It’s FDA-approved and can be used in both the clinic and the O.R., for new diagnosis and also monitoring those who are battling the disease.
