Does coffee have chemicals that can cause cancer? | The Times of India
However, studies suggest something else, a few studies done on the topic show that coffee is not associated with cancers in general. A few studies have been associating coffee with the risk of bladder cancer and lung cancer, but no conclusive evidence has been obtained.
In colorectal cancer, liver cancer and breast cancer, coffee has also been shown to have a protective effect.
Now, one must understand that none of these is absolute, and a lot more studies are needed regarding this to prove a protective or destructive association conclusively. Polyphenols present in coffee are known to have a beneficial effect in preventing cancer and other diseases such as hypertension and heart disease; while acrylamide present is known to be carcinogenic with an association seen with lung and bladder and blood cancers.
