Mendelian Susceptibility to Environmental Cancer

Mendelian Susceptibility to Environmental Cancer (MSEC) is a rare genetic condition where a person’s inherited genes make them more vulnerable to developing cancer from environmental exposures, like certain chemicals or infections. These genetic differences impair the immune system’s ability to detect and repair damage caused by environmental carcinogens. As a result, individuals with MSEC have a higher risk of developing cancer when exposed to specific environmental factors, highlighting the importance of personalized precautions and monitoring for those with this genetic susceptibility.
