✦ Synopsis

The risk of cancer can be increased by both genetic predisposition and environmental exposure. A common mechanism, mutation, may be involved in both.

The rate of mutation in germ cells is the principal determinant of the incidence of genetically predisposed individuals, whereas the rate in somatic cells is the principal determinant in those not so predisposed. Many environmental carcinogens produce their effects via increased somatic mutation rates. The individuals of a population may be classified according to the operation of genetic predisposition, exposure to environmental carcinogens (mutagens), both, or neither. This last group reflects "background" somatic mutation rates.

## Abstract The fifth base in human DNA, 5‐methylcytosine, is inherently mutagenic. This has led to marked changes in the distribution of the CpG methyl acceptor site and an 80% depletion in its frequency of occurrence in vertebrate DNA. The coding regions of many genes contain CpGs which are methy

Approximately half of all colorectal cancers show p53 (TP53) gene mutations, with higher frequencies observed in distal colon and rectal tumors and lower frequencies in proximal tumors and those with the microsatellite instability or methylator phenotypes. Alterations to this gene appear to have lit
