My dad was diagnosed with prostate cancer in 2001, a few months after my mom had a hysterectomy for uterine cancer. In 2007, my dad was diagnosed with a second (unrelated) cancer–something horrible called lyposarcoma with a 15 pound tumor in his abdomen. A month after my father died in 2011, my mother was diagnosed with breast cancer, her second (unrelated) cancer.
How common was cancer in the past? If cancer is more common now than before it could be because:
1) we’ve polluted our environment
2) we live longer than in the past, so we die from things we wouldn’t have had the chance to die from in the Middle Ages
3) we’ve circumvented natural selection with our advances in medicine so we are frailer than in the past (my entire family might have died from appendicitis before reproducing, for example)
I can’t answer whether or not cancer is more common, but it was common enough in the past to be remarked upon and studied:
“Since the earliest medical records were kept, cancer as a disease has been described in the history of medicine. The earliest known descriptions of cancer appear in seven papyri, discovered and deciphered late in the 19th century. They provided the first direct knowledge of Egyptian medical practice. Two of them, known as the “Edwin Smith” and “George Ebers” papyri, contain descriptions of cancer written around 1600 B.C., and are believed to date from sources as early as 2500 B.C. The Smith papyrus describes surgery, while the Ebers’ papyrus outlines pharmacological, mechanical, and magical treatments.
Based on the information recorded on papyri and hieroglyphic inscriptions, ancient Egyptians were able to distinguish benign tumors from malignant tumors. They were also able to use different treatments, including surgery, and other various modes of medicine.” http://training.seer.cancer.gov/disease/history/
A recent article reports on the discovery of a 2250 year old mummy who had prostate cancer: “It is the oldest known case of prostate cancer in ancient Egypt and the second-oldest case in history … The earliest diagnosis of metastasizing prostate carcinoma came in 2007, when researchers investigated the skeleton of a 2,700-year-old Scythian king who died, aged 40-50, in the steppe of Southern Siberia, Russia.” http://www.msnbc.msn.com/id/45126192/ns/technology_and_science-science/
No matter how slow and painful a cancer death might be, surgery didn’t sound like a great option: “The Edwin Smith Papyrus, describes 8 cases of tumors or ulcers of the breast. The document acknowledged that there is no treatment for this condition and recommended cauterization (the fire drill) as a palliative measure. ” http://medicineworld.org/cancer/history.html
“Hippocrates believed that the body had 4 humors (body fluids): blood, phlegm, yellow bile, and black bile. When the humors were balanced, a person was healthy. Too much or too little of any of the humors caused disease. An excess of black bile in various body sites was thought to cause cancer. This theory of cancer was passed on by the Romans and was embraced by the influential doctor Galen’s medical teaching, which remained the unchallenged standard through the Middle Ages for over 1,300 years. During this period, the study of the body, including autopsies, was prohibited for religious reasons, which limited progress of medical knowledge.”
Hippocrates was also the person to coin the term ‘cancer’ from “the Greek words, carcinos and carcinoma . . . thus calling cancer “karkinos.” The Greek terms actually were words to describe a crab, which Hippocrates thought a tumor resembled.” http://cancer.about.com/od/historyofcancer/a/cancerhistory.htm
“The oldest available specimen of a human cancer is found in the remains of skull of a female who lived during the Bronze Age (1900-1600 BC) The tumor in the womens skull was suggestive of head and neck cancer. The mummified skeletal remains of Peruvian Incas, dating back 2400 years ago, contained abnormalities suggestive of involvement with malignant melanoma. Cancer was also found in fossilized bones recovered from ancient Egypt. Louis Leakey found the oldest possible hominid malignant tumor in 1932 from the remains of a body, which could be either that of Homo erectus or an Australopithecus. This tumor had features suggestive of a Burkitts lymphoma.” http://medicineworld.org/cancer/history.html
Throughout, doctors have tried to get a handle on it:
“Zacutus Lusitani (1575-1642) and Nicholas Tulp (1593-1674), 2 doctors in Holland, concluded at almost the same time that cancer was contagious. They made this conclusion based on their experiences with breast cancer in members of the same household. Lusitani and Tulp publicized the contagion theory in 1649 and 1652, respectively. They proposed that cancer patients should be isolated, preferably outside of cities and towns, in order to prevent the spread of cancer.” http://www.cancer.org/Cancer/CancerBasics/TheHistoryofCancer/the-history-of-cancer-cancer-causes-theories-throughout-history
There were treatments too, not that they necessarily worked:
“Paul of Aegina (~625 – 690 AD)
Paul of Aegina was a most prominent Byzantine physician who believed cancer of the breast and uterus were most common, and he wrote that surgery of uterine cancer was useless. He recommended removal of breast cancer instead of cauterization.
Moses Maimonides (1135 – 1204 AD)
The treatment of large tumors suggested by Moses Maimonides involves ‘excis[ing] the tumor and uproots the entire tumor and its surroundings up to the point of healthy tissue, except if the tumor contains large vessels…[or] the tumor happens to be situated in close proximity to any major organ, excision is dangerous.'” http://knol.google.com/k/history-of-cancer-treatment#
