"IT'S JUST GOOD CLEAN SOOT, MICHAEL!"
When we were last discussing chimney sweeps, Mary Poppins the movie, and scrotal cancer, I mentioned how unpredictable cancer can be. Often cancer develops years after the exposure that mutates and changes cells so that they eventually become cancerous.
That's what happens with scrotal cancer. Boys sent up those 17th and 18th century chimneys were exposed to the carcinogen (soot), later developing the cancer in adulthood(1). If they continued in the profession as men, protection from soot didn't improve just because they kept their clothes on. English(2) sweeps of the time wore loose clothing that allowed soot to creep into all sorts of bodily crevices.
How did Percival Pott(3) know to associate scrotal cancer with chimney sweeping? It's a very rare form of cancer, but it happened so frequently amongst the profession that the sweeps had a name for it - Soot Wart!
HOW DO YOU TREAT SOOT WART WHEN YOU DON'T EVEN HAVE ELECTRICITY, INDOOR PLUMBING, OR IBUPROFEN?
Onset of the warty growths usually occurs between the ages of 20 and 40. Sometimes the sweeps would just cut the "wart" out by themselves, with a knife - ouch! - and hope for the best. Without some kind of attention, the cancer could eventually spread throughout the inner thigh, invade genitals, and eventually enter the pelvic cavity. What a horrible way to die!
1. As stated in the last post, although these boys were all exposed to soot, not all of them would develop the cancer.
2. As opposed to German and other European sweeps who wore tighter clothing and had little or no incidence of scrotal cancer.
