Breast cancer is a life-threatening disease in which abnormal breast cells grow uncontrollably, forming tumors. If these tumors go untreated, they can spread to other parts of the body, becoming fatal. Breast cancer typically begins inside the milk ducts or the milk-producing lobules of the breast. While early-stage breast cancer (in situ) is non-invasive and not immediately life-threatening, it can progress if left unchecked. Invasive cancers can spread to surrounding tissues, leading to the formation of tumors and potentially metastasizing to other organs.

How Breast Cancer Develops

Breast cancer starts when abnormal cells in the breast tissue begin to grow uncontrollably. The process often begins in the milk ducts or lobules and, in early stages, does not pose a major risk. However, as the cancer progresses, it can invade nearby tissues, causing tumors that may be felt as lumps or areas of thickening in the breast.

Metastasis

When breast cancer cells spread beyond the breast to other parts of the body, such as the lymph nodes, bones, liver, or brain, it is known as metastasis. Metastatic breast cancer is life-threatening and significantly harder to treat.

Scope of the Problem: Global Statistics

Breast cancer is a widespread issue affecting women worldwide. In 2022, approximately 2.3 million women were diagnosed with breast cancer, leading to around 670,000 deaths globally. The disease affects women in every country, particularly as they age.

Inequities in Breast Cancer Burden

There are noticeable global disparities in breast cancer diagnosis and mortality rates. In high-income countries, 1 in 12 women will be diagnosed with breast cancer, with a mortality rate of 1 in 71. In contrast, in lower-income regions, 1 in 27 women are diagnosed, but 1 in 48 women will die from the disease. This reflects the gap in access to quality healthcare, early detection, and treatment.

Who Is at Risk?

Gender and Age

The primary risk factor for breast cancer is being female. Although breast cancer can occur in men, they account for only 0.5–1% of all cases. Women over the age of 40 are at a much higher risk, with about half of all breast cancers occurring in women without any specific risk factors other than age and gender.

Other Risk Factors

  • Genetic Mutations: Mutations in genes such as BRCA1, BRCA2, and PALB-2 significantly increase the risk of breast cancer.
  • Lifestyle Factors: Obesity, excessive alcohol consumption, and tobacco use can also heighten the risk.
  • Reproductive History: Factors such as the age of menstruation onset, age at first pregnancy, and hormone replacement therapy during menopause affect the likelihood of developing breast cancer.

Most women diagnosed with breast cancer do not have a known family history of the disease, making routine screening crucial for early detection.

Signs and Symptoms of Breast Cancer

Early detection of breast cancer can significantly improve treatment outcomes. While many people with early-stage breast cancer experience no symptoms, there are key indicators to watch for:

  • A lump or thickened area in the breast, often painless
  • Changes in breast size, shape, or appearance
  • Dimpling, redness, or pitting of the breast skin
  • Changes in nipple appearance or discharge from the nipple, including blood

Although most breast lumps are benign, it’s essential to consult a healthcare provider if any changes are noticed.

Treatment Options

Surgical Options

The primary treatment for breast cancer often involves surgery, which may include:

  • Lumpectomy: Removing the tumor and some surrounding tissue
  • Mastectomy: Removing the entire breast
  • Lymph Node Removal: Assessing whether cancer has spread to nearby lymph nodes

Radiation Therapy

Radiation is used to eliminate any remaining cancer cells after surgery, reducing the risk of recurrence. For advanced cases, radiation may also be used to manage symptoms.

Medical Treatments

Breast cancer treatment often includes medications like hormonal therapies, chemotherapy, or targeted biological therapies:

  • Hormonal Therapies: Used for cancers that express estrogen or progesterone receptors, these treatments lower the risk of recurrence by nearly 50%.
  • Chemotherapy: Necessary for hormone receptor-negative cancers, chemotherapy helps shrink tumors and reduce the chances of cancer spreading or returning.
  • Targeted Biological Agents: For HER-2 positive breast cancer, drugs like trastuzumab are combined with chemotherapy to target cancer cells.

The Importance of Early Detection and Completing Treatment

Early detection of breast cancer, followed by timely and comprehensive treatment, greatly improves survival rates. Skipping or delaying parts of the treatment regimen can reduce the effectiveness of the therapy.

Global Efforts and Future Outlook

There has been notable progress in reducing breast cancer mortality rates in high-income countries, with a 40% decline from the 1980s to 2020. The success of these efforts is largely due to improved access to early detection methods and better treatment options. To continue reducing breast cancer mortality globally, health systems need to strengthen their capacity to provide effective cancer treatments and establish reliable referral pathways for care.

Breast cancer serves as a model for managing other cancers, such as cervical, lung, and prostate cancer, as similar care pathways are necessary to ensure early diagnosis and effective treatment.

Conclusion

Breast cancer remains a major health concern worldwide, but early detection, timely treatment, and a comprehensive approach to care can significantly improve outcomes. Awareness of the symptoms and risk factors, combined with advancements in treatment options, has the potential to reduce breast cancer mortality rates globally.
