This is definitely one of the grossest pimple pops of all time. Even those who love these videos find this one quite disturbing as massive amounts of gook comes flying out of the huge cyst on this man’s back. This is one you will have to see to believe. And as a bonus, you get 4 more gross pops. The last one is the king of them all.
What is a Cyst?
A cyst is a closed sac, having a distinct membrane and division compared with the nearby tissue. Hence, it is a cluster of cells that have grouped together to form a sac (not unlike the manner in which water molecules group together, forming a bubble); however, the distinguishing aspect of a cyst is that the cells forming the “shell” of such a sac are distinctly abnormal (in both appearance and behaviour) when compared with all surrounding cells for that given location.
It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst may sometimes resolve on its own. When a cyst fails to resolve it may need to be surgically removed but this will depend on what type of cyst it is and where in the body it has formed.
Cancer-related cysts are formed as a defense mechanism for the body, following the development of mutations that lead to an uncontrolled cellular division. Once that mutation has occurred, the affected cells divide incessantly (and become known as cancerous), forming a tumour.
