by | Dec 10, 2020

■ IARC (International Agency for Research on Cancer) of the WHO maintains different groups of carcinogens based on current scientific evidence for carcinogenicity. The list includes;

Group  Description 
Group 1: Carcinogenic to humans Enough evidence to conclude that it can cause cancer in humans
Group 2A: Probably carcinogenic to humans Strong evidence that it can cause cancer in c. humans, but at present it is not conclusive
Group 2B Possibly carcinogenic to humans Some evidence that it can cause cancer in humans but at present it is far from conclusive.

■ Remember carcinogens do not cause cancer at all times/circumstances. The list describes the level of confidence that something can cause cancer; not how likely it will cause cancer 

■ The public has been conditioned to think chemicals when they think of cancers. The truth is that many other substances are listed in Group 1 (carcinogenic to humans) by the IARC. 

Substances in Group 1 that would surprise you!

  • Alcohol” c Drinks (Beer; Wine, Whisky etc) 
  • Indoor & Outdoor Pollution
  • Wood-dust
  • Processed Meat
  • Areca Nut (Supari)
