A Brief History of Breast Cancer
Breast cancer diagnostics, treatment and prevention has come a long way since its humble beginnings in ancient Egypt. Check out the history of this common and, at least to early doctors, extremely puzzling disease.
Breast cancer is among the most well-known and researched cancers in the medical world today. A diagnosis of breast cancer in 2012, while certainly terrifying, is no long the death sentence it was several years ago. In fact, women who detect breast cancer early in its development have a very good chance of a cancer-free future. But this was not always the case.
The first mention of cancer of any kind was a case of breast cancer documented in Egypt around 1600 BC. The Edwin Smith Papyrus, an ancient text found in 1860 in an Egyptian tomb, described eight cases of tumors or ulcers of the breast. The first doctors attempting to treat breast cancer using this method wrote of the mysterious disease: “There is no treatment!”
Without the benefit of 21st century diagnostics, physicians and medical researchers throughout history posited the following theories regarding the cause of breast cancer: humoralism, divine punishment, lack of (or too much) sexual activity, physical injuries, fear of breast cancer.
Cases of breast cancer in ancient times were often attributed to what Hippocrates called “the wandering womb.” This particular explanation hinged on the belief that a woman’s uterus could move throughout the body leaving health problems of every kind in its wake.
It was not until the 19th century, when improvements in sanitation and disease control dramatically increased the average lifespan of women, that breast cancer became a common disease that demanded serious attention from the medical community.
French surgeon Jean Louis Petit and later Scottish surgeon Benjamin Bell were the first to surgically remove lymph nodes, breast tissue and chest muscle as a treatment for the disease. This method was the first successful treatment of breast cancer.
Surgeon William Stewart Halsted began performing and perfecting mastectomies around 1882. Halsted’s mastectomies were invasive, requiring the removal of both breasts, lymph nodes and underlying muscle. The radical procedure was deemed necessary to prevent the cancer from recurring, but often left its patients with long-term pain and disability.
By the 1970s, researchers began to develop the lumpectomy-a more limited surgical option that removes only the cancerous tumor and any surrounding tissue affected by the tumor. By 1985, research found that a lumpectomy followed by radiation treatment gave women a chance of survival equal to the considerably more invasive mastectomy.
Doctors first used radiation to shrink cancerous tumors of all kinds around the turn of the 20th century. Chemotherapy became an option World War II. It is used to shrink cancerous tumors before surgery, prevent recurrences after surgery and treat cancer that is metastasized, or has spread to other parts of the body.
Scientists began to experiment with ways of combining treatments to improve outcomes. Throughout the 1970s, this exploration led to a better understanding of how cancer spreads through the body. This understanding led to the development of less invasive, but more targeted treatments. This approach to cancer treatments and research continues today.
In 1923, English scientist Janet Lane-Claypon did the first large scale review of women with breast cancer, which identified several risk factors that are still considered valid today--specifically, pregnancy, number of children and age at which menopause started.
In the 1980s and 1990s, thousands of women who had undergone standard breast cancer treatment also received high-dose bone marrow transplants, with the hope that this would improve thier long-term survival rates. Unfortunately, the treatment proved disastrous after 15 to 20 percent of the women died due to the treatment.
A 1995 report from the Nurses’ Health Study and 2002 results of research from the Women’s Health Initiative concluded that hormone replacement therapies, which had become popular among menopausal women, could significantly increase the risk of breast cancer.
In the late 1990s, scientists found that certain variants of the genes BRCA1 and BRCA2 are associated with an 80 percent increase in breast cancer risk. Some women who discover this gene mutation within their genetic makeup will take proactive steps to reduce their risk of cancer, including preemptive mastectomies and even hysterectomies.
As scientists deepen their understanding of the role of genetics in breast cancer risk, research has turned to developing individualized breast cancer treatments based on a woman’s genetic makeup. Meanwhile, some research focuses on techniques to repair or even replace harmful genes before breast cancer occurs.
As research continues to improve, there are steps that every person can take to prevent breast cancer or any kind of cancer: eat a healthy diet, get regular exercise, keep your weight down, and avoid alcohol whenever possible. Also, follow the recommended screening guidelines, which include regular self-exams and annual mammograms after 40 years old.
