Molecules called reactive oxygen species, which include so-called 'free radicals', have long been viewed as damaging byproducts of our body’s metabolism – a reason why antioxidant supplements have been considered as a potential way of reducing cancer risk.
Now, scientists have discovered that certain immune cells depend on these very molecules to activate and destroy cancer cells, and that tumours exploit this dependency by releasing natural antioxidants to shut down the immune attack.
