carcinogens that cause cancer

Carcinogenic means it causes cancer.

Paraffin Wax isn't carcinogenic. It's comprised of long chains of benign hydrocarbons, and is commonly used in food itself. In fact, there's a term "Food-Grade Paraffin Wax".

quite damaging to the environment

You said yourself Paraffin wax is a byproduct of oil refinement. The actual process of making the wax is harmless, but obtaining the oil is hazardous. However, since we're not done making oil anytime soon, it's pretty harmless to use the byproducts to make some candles eh?

I understand this, but Paraffin Wax, assuming it contains what it should, and no additives, is entirely harmless.

I know it doesn't mean a lot, that there's a lot of stories, but my aunt had breast cancer, and it didn't look very good for her. She did very well in Chemo and never lost her smile, and she's absolutely fine now. She's been cancer free for so long. Don't lose your smile. :)
