Our cells become damaged over time and one function of our immune system is to survey for damage and can "tag" cells to "self-destruct" (i.e. apoptosis) if the damage is too severe. One simple way of viewing cancer is specific mutations that remove the mechanism by which damaged cells can destroy themselves is lost. As well as potential other mutations that unregulate growth. Combined, this leads to damaged cells with no "brake pedal" to speak of continuously grow with no end. And the cancer that manifests as clinical disease are due to cancers that typically can evade the immune system's means of destroying the cells. Over the course of your life you absolutely will have an indeterminate number of "precancerous" or even cancerous cells that are dealt with by your immune system that you wouldn't ever know about. There are certain cancers that wouldn't ever manifest in a person with a healthy immune system, and their presence basically is an "AIDS defining illness" in the setting of being HIV+. It's why the new direction in cancer therapies are monoclonal antibodies and there is such an emphasis on genetic testing to determine susceptibility of certain tumors to respond to basically a pharmacological, targeted version of human immune systems. --- ...
