Liver cirrhosis is associated with liver cancer being ane of the most deadly cancers due to lading of viral hepatitis transmissionFourthly , hormonal imbalances are similar in motion to non-mutagenic carcinogens as they urinate excessive growth of cells . For example hyper-estrogenic states promote endometrial cancerFifthly , insubordinate system dysfunction and HIV are associated with Kaposi s sarcoma and non-Hodgkin s lymphoma . HPV (human papilloma virus ) is associated with cervical cancer and anal cancerSixthly , heredity is one more cause of cancer , but slide fastener depends on the person as cancer may be unconditioned . Many forms of cancer are sporadic inwardness they can t be inherited , but there are number of recognized syndromes of hereditary cancer . Examples are Li-Fraumeni syndrome outlook tumors , colonic polyposis , familial adenomatus polyposis hereditary non-polyposi s colorectal cancer , etcConclusion...If you exigenc! y to get a full essay, order it on our website: OrderCustomPaper.com
