We know that often patients suffer from cancers of the colon, breast, lung, etc but rarely we encounter patient suffering from cardiac cancer, what is the protective mechanism which saves cardiac cells from cancer has been answered by a scientist in a study. In an Opinion publishing in Trends in Cancer, researchers propose that this vulnerability in some organs may be due to natural selection.
Humans can tolerate tumors in large or paired organs more easily than in small, critical organs, such as the heart, and so the larger organs may have evolved fewer mechanisms to defend against cancerous cells. "The organs that are the most important to keeping you alive and capable of reproduction, such as the heart, brain, or uterus, may enjoy a better protection against cancer, all other things being equal," says an evolutionary biologist at the Center for Ecological and Evolutionary Cancer…
