Katie, glad you are back and posting on your thread. As a new member I didnt want to see anything scare you off as I know this site can be a very important place for support and info for you.
There are quite a few here who are young and have no known cause. There could be a million reasons why this has happened. At this time there is so much that is still to be learned about cancer including causes. Why one seemingly healthy person will get OC while their best friend is a smoker, heavy drinker and also is
HPV+ but never gets OC. The whole thing stinks but we have to do what is necessary to kill the cancer and hopefully move on to live a good long healthy life afterwards.
Please feel free to ask any questions and we will try to help you.
