The reason why people with cancer due to asbestos exposure do not transfer (pass) the mutation unto their offspring is because the mutation occurred in somatic cells.
Cancer can be defined as the uncontrolled division of certain somatic cells, which then invade the surrounding tissues and interfere with the normal functioning of the human body.
Over the years, the exposure and inhaling of building material such as asbestos into the lungs has been linked to the cause of certain types of cancers such as mesothelioma. This building material (asbestos) results in the mutation of the p53 gene, which is mainly responsible for controlling tumor suppression in living organisms.
However, people that develop cancer due to an exposure to asbestos, do not transfer (pass) the mutation unto their offspring because the mutation took place in somatic cells rather than in sperm and egg cells.
