Question:
How is nitrosoamines linked to cancer and what are they anyway?



Replies:
To see the structure of nitrosamines, search nitrosamine on Wikipedia. Nitrosamines cause cancer by inducing mutations in somatic (body) cells. Almost all cancers arise as a result of a mutation in a body cell which inactivates the cell's control mechanism that prevents the cell from dividing too often. All tumors are a clone of mutated cells that started from one mutated cell, so anything that causes mutations can be expected to cause cancer. A mutation is any change in the base pair sequence in a cell's DNA. This theory of carcinogenesis is known as the somatic mutation hypothesis.
