Lasers cure nearly 50% of patients with prostate cancer in new study

Experts have honed a cutting-edge method to kill off tumors with less damage to healthy cells.

Researchers at the Weizmann Institute of Science in Israel and STEBA Biotech have announced the success of the unique method they developed to fight prostate cancer. This treatment, which the group of expects called “transformative,” has shown promising results.

Under development since 2011, vascular targeted photodynamic therapy (VPT), as the procedure is called, is carried out in a two-step process. Patients are first introduced to WST11 — a compound extracted from some benthic bacteria, or bacteria that dwell at the bottom of the sea. These bacteria are particularly special, though, as they are highly light-sensitive.

Optical fibers are then inserted through an area called the perineum, found between the the testes and the anus, and directly into the prostate gland. Afterwards, the scientists turn on a red laser that is induced through the optical fibers. This process utilizes the photosensitivity of the WST11 drug and activates it. Upon activation, free radicals are released within the area, attacking and destroying the tumors. Unlike conventional treatments which might affect a general area of body cells, this treatment is localized. The nearby cells are left more or less unharmed.

Dogs can sniff the scent of prostate cancer with 98% accuracy

Dogs’ noses have four times the number of olfactory cells as humans.

Dogs noses are powerful and it has been well documented what they are able to sniff out. Researchers have discovered that our canine companions’ snouts may be more accurate than advanced laboratory procedures when it comes to detecting certain forms of cancer.

Science may have just beaten Prostate Cancer

Did we win this battle?
How do you know when your new cancer drug is working better than expected? When they shut down the clinical trial so that every participating patient can receive it.

Johnson & Johnson’s Zytiga is kind of a big deal. The FDA approved its use last year for advanced prostate cancer patients who had already received chemo but whose cancer had still metastasized. Prostate cancer is typically treatable for the 200,000 American men who contract it annually, as long as it is caught before it spreads…
