Breast cancer has been called Nun's disease because of the high number of nuns affected dating back to the 1700s.(Photo: fstop123 / Getty Images)
Have you heard the termNun's Disease?
My guess is you may not have as the phrase has become somewhat outdated over time.
The inception of the term became popular hundreds of years ago due to the high number of nuns being diagnosed with breast cancer, compared to diagnoses in the non-nun population of women.
As early as 1700, Dr. Bernardino Ramazzini, an Italian physician, considered to be the founder of "occupational medicine"recognized there was one female profession whose members were far more likely to die from breast cancer than any other female community, and that was the nun occupation.

So why is this?
The answer is that lifelong nuns, comparable to all women who have not been reproductive, are at an increased risk of breast cancer, along with ovarian and uterine cancers, compared with women who have given birth.
Evidence supporting the Nun's Disease theory points to the protective side-effects of having children and breastfeeding in decreasing the chances of breast cancer.
As an example, the link connecting breast cancer and reproduction was long suspected, but not proven until a British study evaluated data from more than 150,000 women in 30 countries.
The outcome of the research continued to point to hormone related fluctuations in estrogen levels during pregnancy and while breastfeeding, decreasing breast cancer diagnoses in women who had reproduced.
In addition, a 1920s British physician, Dr. Janet Lane-Claypon, did epidemiological research that demonstrated the number of children a woman had, length of lactation, and age of first pregnancy also affected the accumulative risk of a breast cancer diagnosis.
According to WebMD, a woman has a 7% decreased risk of breast cancer per birth, and her chances drop another 4% for every year of breastfeeding.
In line with WebMD, sources from the Susan G. Komen Breast Cancer Foundation state, women who give birth for the first time after age 30 are up to two times as likely to develop breast cancer as women who have their first child before the age of 20.
In addition, women who have children over the age of 35 have a slightly higher risk for breast cancer than women who dont have children at all.
Its also estimated that 5 percent of breast cancers could be prevented every year if women were to breastfeed their children for an extra six months.
If you have chosen to remain child free, the most realistic approach to reducing breast cancer is to focus on early detectionand be aware of any genetic risk factors that could contribute such as a family history; its also important to focus on reducing dietary risks such as not smoking, drinking excessively, maintaining a healthy dietand exercising regularly.
Of course, the best trajectory is to do monthly self-breast exams and take preventative clinical measures.
Self-breast exams will help detect changes that might be indicative of growths such as cancer tumors.
It's important to note that self-examinations are solely not enough, as breast screenings and mammograms are evidenced based and a must for early detection.
The American College of Radiology has reported that mammography has reduced breast cancer mortality in the United States by almost 40% since 1990.

Duringthe past several years there have been several updates, changes, and confusion regarding guidelines and safety precautions for breast screenings, so here is what you need to know.
The American College of Physicians (ACP) offers four recommends for women:
1.In average-risk women aged 40 to 49 years, clinicians should discuss whether to screen for breast cancer with mammography before age 50 years. Discussion should include the potential benefits and harms and a woman's preferences. The potential harms outweigh the benefits in most women aged 40 to 49 years.
2. In average-risk women aged 50 to 74 years, clinicians should offer screening for breast cancer with biennial mammography.
3. In average-risk women aged 75 years or older or in women with a life expectancy of 10 years or less, clinicians should discontinue screening for breast cancer.
4.In average-risk women of all ages, clinicians should not use clinical breast examination to screen for breast cancer.
Simply, the goal of mammography is the early detection of breast cancer, typically, through detection of characteristic masses or microcalcifications.
Annual mammograms can help detect breast cancer in the earliest stages, when it is most treatable, while also detecting changes that a woman would not notice on her own, until months later.
The US Census Bureau Population Survey stated in 2014, 47.6 percent of women between the ages of 15 and 44 had not had children, an increase of 46.5 percent from 2012.
These statistics represent the highest percentage of childless women since the bureau began tracking the data back in 1976, and sure to be influencing the increased breast cancer diagnoses in our country.
According to BreastCancer.org, one in eight women (about 12-percent) will develop invasive breast cancer over the course of her lifetime.
This year, an estimated 268,600 new cases of invasive breast cancer were expected to be diagnosed, along with 62,930 new cases of non-invasive breast cancer.
For women who have chosen to be childfree, or considered to be of high-risk for breast cancer, they should seek a breast surgeon to quantify those risks; while discussing the potential diagnostic role of a breast MRI and/or medications to reduce risk.
Childfree or not, high risk or not, its important to focus on preventative breast health, to keep any potential breast cancer risks at a minimum.
