  2. Carcinogenesis - Wikipedia

    en.wikipedia.org/wiki/Carcinogenesis

    Cancers and tumors are caused by a series of mutations. Each mutation alters the behavior of the cell somewhat. Carcinogenesis, also called oncogenesis or tumorigenesis, is the formation of a cancer, whereby normal cells are transformed into cancer cells.

  3. Causes of cancer - Wikipedia

    en.wikipedia.org/wiki/Causes_of_cancer

    Hereditary cancers are primarily caused by an inherited genetic defect. A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes ...

  4. Mutagen - Wikipedia

    en.wikipedia.org/wiki/Mutagen

    The international pictogram for chemicals that are sensitising, mutagenic, carcinogenic or toxic to reproduction. 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.

  5. Mutagenesis - Wikipedia

    en.wikipedia.org/wiki/Mutagenesis

    It can also be achieved experimentally using laboratory procedures. A mutagen is a mutation-causing agent, be it chemical or physical, which results in an increased rate of mutations in an organism's genetic code. In nature mutagenesis can lead to cancer and various heritable diseases, and it is also a driving force of evolution.

    The German professor Wilhelm Fabry believed that breast cancer was caused by a milk clot in a mammary duct. The Dutch professor Francois de la Boe Sylvius, a follower of Descartes, believed that all disease was the outcome of chemical processes and that acidic lymph fluid was the cause of cancer.

    CHICAGO, March 23 (Reuters) - About two-thirds of cancers are caused by random typos in DNA that occur as normal cells make copies of themselves, a finding that helps explain why healthy ...

  8. Malignant transformation - Wikipedia

    en.wikipedia.org/wiki/Malignant_transformation

    In cancers, loss of gene expression occurs about 10 times more frequently by epigenetic transcription silencing (caused, for example, by promoter hypermethylation of CpG islands) than by mutations. As Vogelstein et al. [ 16 ] point out, in a colorectal cancer there are usually about 3 to 6 driver mutations and 33 to 66 hitchhiker , or passenger ...
