Breast Cancer

Breast cancer is by far the most common cancer affecting women worldwide, and it is the most common cause of cancer death in women. A number of genetic variants have been identified that significantly impact the risk of developing breast cancer.

History of breast cancer

Breast cancer may be one of the oldest known forms of cancer tumors in humans. In approximately 3,500 year old writings of an Egyptian physician, tumors of the breast are described followed with a statement that this was an incurable disease. For centuries, physicians described similar cases in their practises, with the same sad conclusion.

When medical science gained a greater understanding of the circulatory system in the 17th century, the link was established between breast cancer and its distribution via the lymph nodes in the armpit. The French surgeon Jean Louis Petit (1674-1750) and later the Scottish surgeon Benjamin Bell (1749-1806) were the first to remove the lymph nodes, breast tissue, and underlying chest muscle. Their successful work was carried on by William Stewart Halsted who started performing mastectomies in 1882. He became known for his Halsted radical mastectomy, a surgical procedure that remained popular up to the 1970s.

Breast cancer portrayed by Rembrandt

“In 1967, an Italian surgeon touring Amsterdam’s Rijks museum stopped in front of Rembrandt’s painting Bathsheba at Her Bath, on loan from the Louvre, and noticed an asymmetry to Bathsheba’s left breast; it seemed distended, swollen near the armpit, discolored, and marked with a distinctive pitting. With a little research, the physician learned that Rembrandt’s model, his mistress Hendrickje Stoffels, later died after a long illness, and he conjectured in a celebrated article for an Italian medical journal that the cause of her death was almost certainly breast cancer”.
(From the book Bathsheba’s Breast: Women, Cancer, and History, by James S. Olson).

Mammary tumors in mammals other than humans

Did you know that dogs, as well as most other mammals, can develop breast cancer too? Breast cancer is a mammary tumor originating in the mammary gland, and can therefore develop in all mammals. It is common in older female dogs and cats that are not spayed, but also found in other animals. Interestingly, mammary tumors are extremely rare in cow, goat, sheep, and horse.
