Deep sea creatures beamed with lasers through the body are the unlikely new cure for the most common cancer among men.
A new treatment involving never-before-seen ocean bacteria can treat mild forms of prostate cancer with hardly any side effects.
Prostate cancer is known to leave men with incontinence and erectile dysfunction when treated with radiotherapy.
But now these life-changing effects on the male organs could become far less common thanks to the breakthrough from scientists at the Weizmann Institute of Science and STEBA Biotech in Israel.
But when these particular bacteria are brought out into light, they become toxic.
Using this reaction, scientists have made a drug which activates when exposed to laser beams, and are able to precisely target cancer cells deep in a man's body.
Half of the 413 patients in the trial of vascular-targeted photodynamic therapy (VTP) saw their tumour go into remission, which boosts hopes for the radical new treatment being rolled out Europe-wide.
VTP is currently under review by the European Medicines Agency (EMA) for possible licence.
