However, studies suggest something else, a few studies done on the subject show that coffee is not associated with cancer in general. Several studies have linked coffee with an increased risk of bladder and lung cancer, but no conclusive evidence has been gathered.
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 this is absolute, and more research is needed on this to conclusively prove a protective or destructive relationship. Polyphenols present in coffee are known to have beneficial effects in preventing cancer and other diseases such as hypertension and heart disease; while acrylamide present is known to be a carcinogen that has been linked to lung, bladder and blood cancers.
