What is the history of breast cancer?

Breast cancer is the second most common cancer among females in the United States. Researchers across the globe are working to find new and improved ways to prevent, detect, and treat breast cancer.

According to the Centers for Disease Control and Prevention (CDC)Trusted Source, breast cancer is the second most common cancer to affect females in the U.S. Males can get breast cancer too, but this is rare.

The American Cancer Society (ACS) notes that approximately 281,550 females will receive a diagnosis of invasive breast cancer in 2021. It also estimates that 43,600 of those will die as a result.

However, due to increased awareness and advances in screening, treatment, and management, death rates from breast cancer decreased by 40% between 1989 and 2017. This equates to 375,900 deaths prevented within that time frame.

This article discusses the history of breast cancer and explains how awareness, screening, and treatment have evolved throughout the years.

Early discovery of breast cancer

According to an article in the journal BBA ClinicalTrusted Source, the earliest descriptions of breast cancer date back to 3500 B.C.

There were many theories about the causes of breast cancer. The sections below look at some of these theories in more detail.

Humoral theory

Although theories varied from expert to expert, both Hippocrates and Galen attributed the development of breast cancer to an “excess of black bile.”

Hippocrates also believed that the body consisted of four fluids: blood, phlegm, yellow bile, and black bile. When these were balanced, a person was healthy. Having too much or too little of one or more of these fluids, however, would cause disease or cancer.

This idea persisted for 1,300 years.

Lymph theory

Eventually, the lymph theory replaced Hippocrates’ humoral theory.

The lymph theory proposed that lymph, not bile, formed cancer. Lymph is the fluid that carries white blood cells throughout the body.

In the 1700s, Scottish surgeon John Hunter supported the theory and agreed that tumors grew from lymph.

Blastema theory

In 1838, a German pathologist named Johannes Müller pushed against the lymph theory. Müller believed that cancer consisted of cells, not lymph.

Müller’s student Rudolf Virchow determined that all cells, even cancerous cells, derived from other cells.

Other theories

Other theories included the following:

  • Chronic irritation theory: Virchow thought that chronic irritation caused cancer. He also incorrectly believed that cancer spread similarly to liquid. However, in the 1860s, a German surgeon called Karl Thiersch noted that cancer travels around the body due to malignant cells spreading.
  • Trauma theory: From the late 1800s to the 1920s, some people thought that trauma caused cancer.
  • Infectious disease theory: In the 1500s, two doctors in Holland thought that cancer was contagious. Some people held this belief throughout the 17th and 18th centuries.

Other theories, including those above, followed Virchow’s discovery.

Early research on breast cancer 

Breast cancer awareness was not a part of mainstream media until the early 20th centuryTrusted Source. In fact, breast cancer activism did not occur until individual females came forward. Support groups, and eventually political activist groups, formed later.

In the early 1970s, surgeons performed radical mastectomies routinely. Back then, surgeons considered radical mastectomies “life saving” procedures. However, when Babette Rosmond — the then-editor of Seventeen magazine — found a lump in her breast, she pushed for alternative treatment.

Rosmond became the first person to publicly challenge breast cancer treatment. This encouraged other people with breast cancer to speak up, fueling the need for more research and funding.

Breast cancer milestones

In the 19th century, advancing technologies provided hope for breast cancer treatment and research. The following are a few milestones worth noting:

Modern treatment options 

Today, healthcare professionals know that breast cancer has subtypes, each of which has a different effect on the body.

Having this deeper understanding of how breast cancer works has led to more personalized treatment options and improved quality of life for both patients and breast cancer survivors.

The CDCTrusted Source lists the following modern treatment options for breast cancer:

  • Surgery: This removes cancerous tissue. There are different types of breast cancer surgeries, including mastectomies and lumpectomies.
  • Chemotherapy: Chemotherapy for breast cancer can shrink and kill cancer cells.
  • Hormonal therapy: This treatment blocks cancer cells from accessing the hormones they require to grow.
  • Biological therapy: Biological therapy works alongside the immune system to fight cancer cells. One example is immunotherapy.
  • Radiation therapy: This uses high energy rays to kill cancer cells.

Special laboratory tests, including liquid biopsies and new imaging tests, are leading the way to quicker and less invasive breast cancer detection.

The ACS lists the following imaging tests as newer experimental tests for breast cancer research:

  • scintimammography, which is a form of molecular breast imaging
  • positron emission mammography
  • electrical impedance imaging
  • elastography

Advances in modern technology not only allow doctors to detect breast cancer earlier. They also give them the ability to determine who needs chemotherapy and who does not.

Today, some people can receive treatment with hormone therapy alone.


According to the ACS, there are more than 3.8 million breast cancer survivors living in the U.S. This number includes those who are currently receiving treatment and those who have finished treatment.

Although it is not currently possible to prevent breast cancer, there are ways to lower one’s risk, including avoiding alcohol, staying physically active, and maintaining a moderate weight.


Breast cancer research has come a long way since the discovery of the condition, but there is still so much more to learn about how it forms and how to treat it effectively.

For now, early detection is the key to successfully treating breast cancer. Performing regular breast self-exams and undergoing routine screenings are two ways to go about detecting breast cancer earlier.
