I don’t know how we got to this in class, but one student who is a caretaker mentioned about one of her clients having a sweat gland tumor – I hadn’t heard of it before.
Looking it up, they did say this is rare.
WebMD reviews a June 2010 study that shows while this is rare, it is increasing in number. They find:
- Non-Hispanic whites had higher rates of skin appendage cancers than Hispanics, African-Americans, and Asian-Pacific Islanders. Non-Hispanic whites had an incidence rate per million of 5.7, compared to 3.7 for Hispanics, 3.5 for African-Americans, and 2.5 for Asian-Pacific Islanders.
- The most common type was cancer of the sweat glands, or more technically, apocrine-eccrine carcinoma.
- Incidence rates increased with age. There was a 100-fold difference between patients 20 to 29 and patients 80 and older.
- Five-year survival rates were 99% for localized disease, but only 43% for cancers that had spread to other parts of the body.
An Indian medical journal states that it could metastasize to the lungs – http://www.cancerjournal.net/article.asp?issn=0973-1482;year=2006;volume=2;issue=4;spage=209;epage=211;aulast=Bahl
American Cancer Society has bulletin board, where someone who has been diagnosed was seeking info and answers – it might be a place to find more information – http://csn.cancer.org/node/242737
Finally, Archives of Pathology reviews 60 cases in a 2001 article – http://www.archivesofpathology.org/doi/pdf/10.1043/0003-9985(2001)125%3C0498%3ACOSG%3E2.0.CO%3B2
Hope it helps!
