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.”"

NHS está a pensar recomendar exame ao fígado para prevenir cirrose

A cirrose quando apresenta sintomas já está em estado adiantado. O SNS do RU está em vias de recomendar um exame médico que detecte alterações precocemente (não invasivo, alternativa a biópsia):

"Dr Andrew Fowell, liver expert at the Portsmouth Hospitals NHS Trust, said: "Identifying people who are at risk of liver disease and offering them non-invasive testing to diagnose cirrhosis is key to ensuring they are given the treatment and support they need early enough to prevent serious complications.
"Ten years ago diagnosis of cirrhosis would often require a liver biopsy, but now with advances in non-invasive testing it is much easier for patients and health professionals to make a diagnosis."
The draft quality standard from NICE recommends a non-invasive scan called transient elastography which uses ultrasound and low-frequency elastic waves to check the liver. A consultation on the draft document is open until February 2017."


Sobre os limites: 5 garrafas de vinho/semana (50 volumes) ou 3,5 para as senhoras.
Citando:
"Women who regularly drink more than three-and-a-half bottles of wine a week should get their livers checked, says new draft advice for England.
For men, the threshold is five bottles of wine a week or 50 units of alcohol, says the National Institute for Health and Care Excellence.
The organisation says GPs should refer "harmful" drinkers for liver scans.
Cirrhosis can be silent until the damage becomes so extensive it stops the liver working."
