  2. Carcinogenesis - Wikipedia

    en.wikipedia.org/wiki/Carcinogenesis

    Development of cancer was proposed in 1971 to depend on at least two mutational events. In what became known as the Knudson two-hit hypothesis, an inherited, germ-line mutation in a tumor suppressor gene would cause cancer only if another mutation event occurred later in the organism's life, inactivating the other allele of that tumor ...

  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. Malignant transformation - Wikipedia

    en.wikipedia.org/wiki/Malignant_transformation

    One underlying commonality in cancers is genetic mutation, acquired either by inheritance, or, more commonly, by mutations in one's somatic DNA over time. The mutations considered important in cancers are those that alter protein coding genes (the exome). As Vogelstein et al. point out, a typical tumor contains two to eight exome "driver gene ...

  5. Cancer - Wikipedia

    en.wikipedia.org/wiki/Cancer

    Deficient expression of DNA repair proteins due to an inherited mutation can increase cancer risks. Individuals with an inherited impairment in any of 34 DNA repair genes (see article DNA repair-deficiency disorder) have increased cancer risk, with some defects ensuring a 100% lifetime chance of cancer (e.g. p53 mutations). [112]

  6. Hereditary cancer syndrome - Wikipedia

    en.wikipedia.org/wiki/Hereditary_cancer_syndrome

    A hereditary cancer syndrome (familial/family cancer syndrome, inherited cancer syndrome, cancer predisposition syndrome, cancer syndrome, etc.) is a genetic disorder in which inherited genetic mutations in one or more genes predispose the affected individuals to the development of cancer and may also cause early onset of these cancers.

  7. Oncogenomics - Wikipedia

    en.wikipedia.org/wiki/Oncogenomics

    Oncogenomics is a sub-field of genomics that characterizes cancer-associated genes.It focuses on genomic, epigenomic and transcript alterations in cancer. Cancer is a genetic disease caused by accumulation of DNA mutations and epigenetic alterations leading to unrestrained cell proliferation and neoplasm formation.

    Scientists previously knew there were two forms of Alzheimer’s disease — familial and sporadic. As the name suggests, genetic mutations cause the familial type. Familial types generally ...

  9. Mutagen - Wikipedia

    en.wikipedia.org/wiki/Mutagen

    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 ...
