Speaker Rtn David Miller - Why does smoking cause cancer. (the Chemistry of Carcinogens) -------------------------- Speaker Finder John Barrow, Visitors Host Grace and Banners Tony Gill, Cash Desk Tony Ashton
David Miller is the ex-headmaster of Woodehouse Grove and studied Chemistry at Oxford. Whist at Oxford he was involved with studying carcinogens. As part of this study it was noted that in 1954 cancer rates amongst women had started to shoot upwards whilst in men it was static. This was because lots of men had always smoked but more women had started during the Second World War.
It is difficult to pinpoint exactly why smoking causes cancer but in 1915 a study showed that coal tar contains lots of compounds (such as toluene, phenols, anthracene and other toxic polycyclic organic compounds) that rapidly cause cancer in laboratory animals. The most carcinogenic of all being dimethyldibenzothiophene which can cause cancer within days of exposure.
David explained that basically the lungs think that such products produced by the half burnt by-products of cigarettes are either cholesterol or testosterone that have similar molecule chains. So they absorb them and then circulate them around the body.
