Other carcinogens may cause cancer through a variety of mechanisms without producing mutations, such as tumour promotion, immunosuppression that reduces the ability to fight cancer cells or pathogens that can cause cancer, disruption of the endocrine system (e.g. in breast cancer), tissue-specific toxicity, and inflammation (e.g. in colorectal ...
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 ...
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 ...
Malignant transformation is the process by which cells acquire the properties of cancer. This may occur as a primary process in normal tissue, or secondarily as malignant degeneration of a previously existing benign tumor .
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 ...
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.
A new Environmental Working Group study says there are contaminants in drinking water that could increase the risk of cancer.
Somatic evolution is the accumulation of mutations and epimutations in somatic cells (the cells of a body, as opposed to germ plasm and stem cells) during a lifetime, and the effects of those mutations and epimutations on the fitness of those cells. This evolutionary process has first been shown by the studies of Bert Vogelstein in colon cancer.
