History
In past centuries, the development of breast cancer was most commonly seen as divine punishment or a trial. From ancient Greek medicine until the end of the 17th century, the dominant medical explanation was an imbalance of the four humors. By the start of the 18th century, humoralism had generally been rejected. Many other theories were put forward, often related to sexual activity: In 1713, Bernardino Ramazzini said that nuns developed breast cancer at a higher rate than married women because they did not engage in sexual intercourse, and the "unnatural" lack of sexual activity caused instability of the breasts; others countered that the cause was frequently too much sexual activity. Other theories from the 18th century included various sorts of problems with the movement of body fluids, such as lymphatic blockages, curdled breast milk or the transformation of pus left after an infection.
In modern times, women are more likely to blame themselves, perhaps deciding that their diet, childbearing history, decision not to breastfeed, or level of exercise is the cause.

Famous quotes containing the word history:
“Books of natural history aim commonly to be hasty schedules, or inventories of God’s property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.”
—Henry David Thoreau (1817–1862)
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
“Look through the whole history of countries professing the Romish religion, and you will uniformly find the leaven of this besetting and accursed principle of action—that the end will sanction any means.”
—Samuel Taylor Coleridge (1772–1834)
