The Evolution of Breast Cancer Treatment – From Ancient Remedies to Precision Medicine and Targeted Therapies

Early history of breast cancer treatment

The history of breast cancer treatment dates back to ancient times when various remedies were used to alleviate symptoms and attempt to cure the disease. In many early civilizations, treatments for breast cancer included the use of herbal remedies, surgical procedures, and topical applications such as poultices.

Ancient Remedies

  • Ancient Egyptians used a mixture of honey and sodium carbonate to treat breast tumors.
  • Greek physician Hippocrates described the disease as “karkinos,” the Greek word for “crab,” which led to the term “cancer.”
  • Ancient Romans employed surgical techniques to remove tumors, although the success rate was limited.

Surgical Interventions

Surgeries for breast cancer were performed as early as the 17th century, with procedures becoming more refined over time. Women like Marie-Anne Victoire Gillain Boivin, a French surgeon, made significant contributions to the field of surgical oncology.

Herbal and Folk Remedies

  • Throughout history, a variety of herbs and plants were believed to have healing properties for breast cancer.

Evolution of Breast Cancer Treatment

One of the significant milestones in the evolution of breast cancer treatment was the introduction of the radical mastectomy by William Halsted in the late 19th century. This procedure involved the complete removal of the breast, underlying chest muscles, and lymph nodes in the armpit. While radical mastectomy was considered the standard of care for many years, advancements in surgical techniques and research led to the development of less invasive procedures.

Surgical Innovations

With the advent of breast-conserving surgery, such as lumpectomy and partial mastectomy, surgeons could remove the tumor while preserving more of the natural breast tissue. This shift in surgical approach aimed to provide effective cancer treatment while improving cosmetic outcomes and reducing the physical and emotional impact on patients.

Radiation Therapy

Another critical development in the evolution of breast cancer treatment was the widespread use of radiation therapy in the 20th century. Radiation therapy involves the use of high-energy beams to target and destroy cancer cells. It can be delivered externally through a machine or internally through implants, depending on the type and stage of cancer.

According to the American Cancer Society, radiation therapy may be used after surgery to kill any remaining cancer cells and reduce the risk of cancer recurrence. It is often recommended for patients who undergo breast-conserving surgery or have a high risk of cancer returning in the chest wall or lymph nodes.

Current Trends

Today, the treatment landscape for breast cancer continues to evolve rapidly with ongoing research and clinical trials exploring new therapeutic options. From targeted therapies and immunotherapy to personalized medicine approaches, the future of breast cancer treatment holds promise for improved outcomes and quality of life for patients.
