In biochemistry, naturally occurring phenols are natural products containing at least one phenol functional group. [1] [2] [3] Phenolic compounds are produced by plants and microorganisms. [4] Organisms sometimes synthesize phenolic compounds in response to ecological pressures such as pathogen and insect attack, UV radiation and wounding. [5]
Some substances cause cancer primarily through their physical, rather than chemical, effects on cells. [32] A prominent example of this is prolonged exposure to asbestos, naturally occurring mineral fibers which are a major cause of mesothelioma, which is a cancer of the serous membrane, usually the serous membrane surrounding the lungs.

Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract. [61] Its corrosive effect on skin and mucous membranes is due to a protein-degenerating effect. [50] Repeated or prolonged skin contact with phenol may cause dermatitis, or even second and third-degree burns. [62] Inhalation of phenol vapor may cause lung ...
The question of seed oils and cancer started because seed oils are high in omega-6 fatty acids, some of which may promote inflammation in the body, research has shown.
Back then in the early 1990s, despite the American Cancer Society focusing on cancer prevention, many people thought that people got cancer mainly because of inherited genes and bad luck, like ...
Aflatoxin B 1, a toxin produced by the fungus Aspergillus flavus which is a common contaminant of stored grains and nuts is a known cause of hepatocellular cancer. The bacteria H. Pylori is known to cause stomach cancer and MALT lymphoma. [24] Hepatitis B and C are associated with the development of hepatocellular cancer.
A growing body of evidence has shown links between cancer and drinking alcohol. In a warning Friday, U.S. Surgeon General Vivek Murthy said cancer risk increases with the number of drinks, but ...
The name derives from the Ancient Greek word πολύς (polus, meaning "many, much") and the word ‘phenol’ which refers to a chemical structure formed by attachment of an aromatic benzenoid ring to a hydroxyl (-OH) group (hence the -ol suffix). The term "polyphenol" has been in use at least since 1894.
