-_- I literally took and passed a Cancer Biology course in my last semester of college, which was this year. There are various characteristics most cancer cells have, but the mutations that cause them are not entirely the same.
Just look at cancer cell karyotypes like these, there is a ton of variation in the genomes of different cancers, regardless of what tissue they are derived from:

However, a unifying trait of all cancer cells is that they have mutations that impair mechanisms which control cell growth and division, among others, and that they themselves originate from normal, healthy cells.
The area of cancer research is extremely important to me personally. Nearly half of my family has either died of or suffered from cancer. A close childhood friend of mine is currently dying of cancer. Nearly everyone on this planet has friends or family that have had the disease or are currently suffering from it, so who DOESN'T care about cancer?
-_- I don't think your commentary could have been directed at a worse atheist than myself when it comes to this topic. My degree is in Biomedical sciences and I went out of my way to take an advanced Cancer Biology course over the Virology course due to personal interests. If you think mutation doesn't have anything to do with cancer, you aren't even on a high school level of understanding cancer.
By the way, you still haven't actually said how you think cells become cancerous. I am waiting for your explanation, and I better not get more along the line of "you couldn't possibly get it" and "you should do your own research" from you in response. Because that's just insulting at this point. Do you even know what Src and p53 are and their relevance to cancer without looking them up? Heck, I'll stream all three episodes of "Cancer, the Emperor of all Maladies" with commentary from me during it just to present that I understand the topic, with additional information to show that I am not gaining the understanding just from the series itself. If that's what it takes to make more people understand cancer, then so be it.
Who wants to watch?
