Cancer facts response

I thought that this article/ website was incredibly useful in finding all the info I personally had questions about. Such as how different types of cancers are there? What are some of the most common symptoms? How is cancer diagnosed? Plus some interesting info about how people can "contract" cancer. whether it be by hereditary inheritance or some other way that I honestly don't know about. I found out that women have a higher chance of getting cancer because of their high levels of estrogen in their systems. I also found out that cancer cannot be passed on by kissing, sharing drinks, skin-to-skin contact or taking care of or being in the same facinity of an infected person. This website was extremely helpful! It had a BUNCH on cancer and how it's sometimes diagnosed and other useful info.
