Study Notes
Common Carcinogens and Their Effects
- Direct alkylating agents are weak carcinogens that can induce lymphomas and leukaemias, but some are used as anti-cancer therapy.
- Polycyclic Aromatic Hydrocarbons are strong carcinogens that can cause skin, sarcomas, and organ cancers. They are found in cigarette smoke and smoked meats and fish.
- Aromatic amines are carcinogenic and are associated with liver and bladder cancers. B-Naphthylamine is linked to bladder cancer.
- Aflatoxin B1 is a mycotoxin that is strongly linked to hepatocellular carcinoma in parts of Africa and China.
- Nitrosamines and Amides are suspected to contribute to the induction of some forms of cancer, particularly gastric carcinoma and are present in food with nitrate preservatives.
- Exposure to asbestos has been associated with an increased incidence of bronchogenic carcinomas, mesotheliomas, and gastrointestinal cancers.
- Hormones such as estrogens serve as promoters of liver tumours.
- High levels of dietary fat have been associated with an increased risk of colon cancer.
- Alcohol consumption increases the risk of development of cancers of the mouth, pharynx, and larynx by over tenfold.
- Ultraviolet rays induce an increased incidence of squamous cell carcinoma, basal cell carcinoma, and malignant melanoma of the skin.
- Ionizing radiation is carcinogenic and is implicated in skin cancers and various malignant neoplasms. Blood and thyroid tissue are the most vulnerable organs to develop radiation-induced cancers.
- HPV, H. pylori, and other viruses like EBV, HBV, and KSHV have been found to be oncogenic and cause cancers in humans.
- Tumour surveillance is not perfect, and tumour cells are capable of evading the immune system, but the immune system can recognise tumour cells and eliminate them.
