Carcinogenesis, also called oncogenesis or tumorigenesis, is the formation of a cancer, whereby normal cells are transformed into cancer cells. The process is characterized by changes at the cellular, genetic, and epigenetic levels and abnormal cell division. Cell division is a physiological process that occurs in almost all tissues and under a ...
Alcohol causes cancers of the oesophagus, liver, breast, colon, oral cavity, rectum, pharynx, and larynx, and probably causes cancers of the pancreas. [2] [3] Cancer risk, can occur even with light to moderate drinking. [4] [5] The more alcohol is consumed, the higher the cancer risk, [6] and no amount can be considered completely safe.
Contents. Mutagen. In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer in animals, such mutagens can therefore be carcinogens, although not all necessarily ...
Genotoxicity is the property of chemical agents that damage the genetic information within a cell causing mutations, which may lead to cancer. While genotoxicity is often confused with mutagenicity, all mutagens are genotoxic, but some genotoxic substances are not mutagenic. The alteration can have direct or indirect effects on the DNA: the ...
The Warburg hypothesis ( / ˈvɑːrbʊərɡ / ), sometimes known as the Warburg theory of cancer, postulates that the driver of tumorigenesis is an insufficient cellular respiration caused by insult to mitochondria. [1] The term Warburg effect in oncology describes the observation that cancer cells, and many cells grown in vitro, exhibit ...
A new Environmental Working Group study says there are contaminants in drinking water that could increase the risk of cancer. New study finds cancer-causing chemicals in tap water Skip to main content
A 2018 study found that tap water has fewer microplastics than bottled water, making it a likely better bet. Filtering your water is another possible way to decrease microplastics in drinking ...
Warburg effect (oncology) In oncology, the Warburg effect ( / ˈvɑːrbʊərɡ /) is the observation that most cancer cells release energy predominantly not through the 'usual' citric acid cycle and oxidative phosphorylation in the mitochondria as observed in normal cells, but through a less efficient process of 'anaerobic glycolysis ...
