Ovarian cancer can strike anyone with ovaries, although it is most common in people who are more than 55 years old. It starts when certain mutations in ovarian cells start to proliferate, resulting in tumor growth. (Some types of ovarian cancer can originate in the fallopian tubes, but most ovarian cancers arise from the cells that cover the surface of the ovary.) If a cancerous cell breaks away, it might set up camp elsewhere in the body, resulting in the cancer’s spread. It can be a serious condition, affecting around one out of 71 ovary-wielding individuals.

What causes ovarian cancer?

If you learned about the reproductive system in school, you probably remember that ovulation involves the release of an egg from an ovary. What your teacher probably didn’t tell you is that the process of ovulation is actually rather violent. An egg does not exit the ovary through a preexisting “doorway” and shuttle down the fallopian tube to make its way to the uterus. Nope, when an egg is “released,” it actually bursts through the ovary itself.

Unfortunately, during ovulation, the egg perforates the ovary, creating a lot of tissue damage. The ovary needs to repair itself, sort of like how bricklayers will need to be hired to fix that mess left by the Kool Aid man. Because ovarian cells are so often replicating themselves during the repair process, there are more chances for an error to occur. Cells that divide frequently, like ovarian cells, are more prone to becoming cancerous. Continue reading →
