well im sorry... but im saying "everyone" as in these pro-earth/nature Gaia loving people. 

Update 2:

    The captain is correct, I would add radon gas, and uranium (a naturally found element)

    Living. I had a cancer as an adult that had been growing since before I was born.

    Synthetic only means it was made in a lab, but it could be chemically identical to a natural substance. So natural doesn't really matter. 

    "Natural" is what a layman thinks is automatically good. 

    "Certain fungi found on plants like corn, peanuts, and tree nuts can contain aflatoxins. Plants used for herbal medicines sometimes contain aristolochic acids. Both of these substances have been linked to the development of cancer."

    aflatoxin on peanuts is a strong carcinogen .

    One of the most common avoidable risk factors for cancer is tobacco use.

    Even when organically grown, the tobacco naturally contains a range of chemical compounds that increase the risk of a variety of cancers.

    Chemicals are not synthetic.

    Do some real research instead of making stupid sweeping claims.

    Too bad false assumptions don't cause it.

    Seriously if you want to know general knowledge questions about cancer read up on it on official cancer sites like Cancer.org.

    It's actually very difficult to determine what the "cause" of cancer really is. One of the standard methods for determining whether a substance is carcinogenic is a test called the "Ames Assay". The challenge is that cancer typically develops over a long period of time after exposure to a cancer-causing agent. Because this is difficult to assess, the Ames Assay involves giving large doses of substances to animals over a limited period and seeing if they develop tumors. A problem is that it's unclear if a massive dose of something for 3 weeks is really comparable to a more realistic very low dose of something for years. Moreover, many very "commonly regarded as safe" substances fail the Ames test. 

    Factor in as well, that some cancers seem to develop on their own, regardless of an individual's exposure to anything. In the US, roughly 1/3 of people develop some form of cancer in their lifetime, and some medical experts believe that nearly all men will develop prostate cancer if they manage to live long enough. 

    Cancer has been noticed in humans for hundreds of years, prior to the invention of many modern chemicals.

    So the odds are that there are a lot of natural things that cause cancer. But it's extremely difficult to determine that an exposure to any given substance years ago resulted in cancer today.
