While browsing Health.SE, I came across an [answer](https://health.stackexchange.com/a/180/6439) that makes the following claim:

>A 2007 study by Nottingham University<sup>2</sup> found that spicy foods can help kill cancer cells. Capsaicin, which is what makes many foods spicy, attacks the mitochondria of the cancer cells, triggering their death.

This footnote links to [this BBC article](http://news.bbc.co.uk/2/hi/6244715.stm), which claims that

>They found capsaicin, an ingredient of jalapeno peppers, triggers cancer cell death by attacking mitochondria - the cells' energy-generating boiler rooms.

This news article does not provide their sources except for a '2007 study by Nottingham University'. I was unable to find anything about this study.

So, I'm skeptical. If this was really discovered in 2007, why haven't I heard of it being used as a cure at all? Why can't I find the study?

**Do hot peppers kill cancer cells?**
