Tratamento novo para cancro da próstata (bactérias tóxicas activadas por luz)

Algo ainda em ensaios com um enorme potencial (dado que todas as opções actuais envolvem riscos elevadíssimos de efeitos secundários terríveis para os homens - impotência e incontinência):

Citando:
"The new treatment uses a drug, made from bacteria that live in the almost total darkness of the seafloor and which become toxic only when exposed to light.
Ten fibre optic lasers are inserted through the perineum - the gap between the anus and the testes - and into the cancerous prostate gland.
When the red laser is switched on, it activates the drug to kill the cancer and leaves the healthy prostate behind."

Terapia não invasiva de cancro da próstata (laser)...

... E a importância da biodiversidade (bactérias marinhas foram a inspiração):

Citando:
"A clinical trial has shown that a new, non-surgical method of treatment for low-risk prostate cancer can effectively kill cancer cells whilst at the same time preserving healthy tissue.
The new treatment is called vascular-targeted photodynamic therapy, or VTP. According to University College London Hospitals (UCLH), the treatment uses a light-sensitive drug, which is injected into the bloodstream. A laser then activates the drug, which eradicates tumour tissue in the prostate.



The drug used is called WST11 and comes from bacteria found at the bottom of the ocean. These bacteria have evolved to turn light into energy in a very efficient way. This trait has been exploited to develop WST11, which UCLH describes as “a compound that releases free radicals to kill surrounding cells when activated by laser light.”"
