Grilling with charcoal, and grilling in general, is associated with creating carcinogens and increasing your risk of cancer. The risk is highest when you cook meat high in fat at high temperatures. There are ways to decrease this risk.
Does burnt BBQ cause cancer?
And for good reason: a number of studies published in the past two decades have turned up evidence that eating charred, smoked, and well-done meat could raise cancer risk—pancreatic, colorectal, and prostate cancers, in particular.
Is barbecuing food bad for you?
Charring causes the formation of HAAs, which has been linked to cancer in animal studies. Further, cooking meats over open flames where fat can drip and produce smoke — think grilling — can lead to the formation of polycyclic aromatic hydrocarbons (PAHs). PAHs have also been linked to cancer formation.
