Question by GuitarNoob1510181: Why does cancer appear in some places more frequently than others?
For example, people get tumors in their lungs, bladder, stomach, intestines, brain, breasts,and other organs but you never see anyone developing cancer on their fingers, feet, thighs, etc… Cancer is suppose to be able to develop on any tissue in the body so why does it appear more frequently in certain areas? Can someone please explain this to me, I really want to know.

It tends to occur more frequently in epithelial tissue because this type of tissue reproduces most frequently. Since it is the replication of cells that goes awry in cancer, it would follow that we would see cancer more frequently in cell types that divide more frequently.
We are also more likely to see cancers in places that are most commonly exposed to carcinogens such as UV radition and environmental toxins. So for this reason, some of the most common cancer places for cancer are the skin, the lungs and the digestive track.
