Breast cancer remains the most commonly diagnosed cancer and the leading cause of cancer death among women worldwide. It is also the most common cancer among women in South Africa, accounting for 22.6% of all female cancers and 16% of cancer deaths among women.” (Source: Breast Cancer Research)

Breast cancer is a pressing global health issue characterised by the abnormal growth of cells in the breast tissue. It is a significant concern because it is widespread, affecting millions of women and even some men worldwide. Breast cancer not only poses a threat to the physical health and well-being of individuals but also carries emotional and socioeconomic implications for patients and their families. This disease transcends geographical boundaries and impacts communities across the globe, making it a critical health concern that demands attention and understanding.

By shedding light on this topic, we aim to empower all women with knowledge about the disease, its potential risk factors, and the measures they can take to reduce their chances of developing breast cancer.

Understanding Breast Cancer

Breast cancer is a malignant condition characterised by the uncontrolled growth of abnormal cells in the breast tissue. These cancerous cells can form tumours that may be confined to the breast or spread to other parts of the body if left untreated. 

1. Types of Breast Cancer:

Breast cancer is not a single disease, but it encompasses various types. Some of the most common types are:

  • Ductal Carcinoma In Situ (DCIS): Early-stage cancer that remains confined to the milk ducts.
  • Invasive Ductal Carcinoma (IDC): The most prevalent type, where cancer cells infiltrate surrounding breast tissue.
  • Invasive Lobular Carcinoma (ILC): Cancer starts in the milk-producing glands and can spread to other breast tissues.
  • Triple-negative breast Cancer: A subtype lacking oestrogen, progesterone, and HER2 receptors.
  • HER2-Positive Breast Cancer: Characterised by an overexpression of HER2 protein.

2. Importance of Early Detection

Early detection is crucial for successful breast cancer treatment. Mammograms and X-ray examinations of the breast play a pivotal role in identifying tumours before they are palpable. 

Regular mammograms, particularly for women over 40, can significantly help detect breast cancer at an early, more treatable stage. Screening also includes breast self-exams and clinical breast exams by healthcare professionals. These methods help identify any abnormalities, encouraging timely medical evaluation and intervention.

Signs and Symptoms of Breast Cancer

Breast cancer can manifest with various signs and symptoms, and it is essential to be aware of these potential indicators:

  • Breast Lump: The most common sign of breast cancer is a lump or thickening in the breast tissue. While not all breast lumps are cancerous, a healthcare provider should evaluate any new, painless lump or mass.
  • Breast Changes: Changes in the breast’s size, shape, or appearance can be a warning sign. This includes unusual dimpling or puckering of the skin, redness, or scaling.
  • Nipple Changes: Changes in the nipple, such as inversion (when it turns inward), discharge (other than breast milk), or a sudden change in direction, should be investigated.
  • Breast Pain: Breast cancer can sometimes cause breast pain, but it’s not typically an early symptom. If you experience persistent, unexplained breast pain, consult a healthcare provider.
  • Skin Changes: Skin changes on the breast’s surface, such as peeling, flaking, or the appearance of an orange peel texture (resembling the skin of an orange), can indicate breast cancer.
  • Swelling in the Armpit or Around the Collarbone: Swelling or lumps in the lymph nodes under the arm or near the collarbone can suggest breast cancer has spread.

It’s important to note that the signs and symptoms of breast cancer can also result from non-cancerous conditions. However, if you notice any of these changes, it’s crucial to consult a healthcare professional promptly for a proper evaluation and diagnosis. 

Risk Factors For Breast Cancer

  • Age and Gender

Women are more susceptible to breast cancer due to the presence of breast tissue, which undergoes hormonal changes throughout life. Hormonal fluctuations, such as those during menstruation, pregnancy, and menopause, can influence the risk. Additionally, the female breast tissue is more complex, with more glandular tissue, making it potentially more susceptible to cancerous changes.

  • Family History and Genetics

Family history plays a significant role in breast cancer risk. Inherited mutations in specific genes, such as BRCA1 and BRCA2, can substantially increase the likelihood of developing breast cancer. These genes repair damaged DNA, and mutations can increase the risk of breast and ovarian cancers. Women with a strong family history of breast cancer may consider genetic counselling and testing to assess their risk.

  • Hormonal Factors
  1. Hormone Replacement Therapy (HRT):

Hormone replacement therapy, used to manage menopausal symptoms, can affect breast cancer risk. Prolonged use of combined oestrogen and progesterone HRT has been associated with a slightly increased risk of breast cancer. Women considering HRT should discuss its potential risks and benefits with their healthcare providers.

  1. Menstrual and Reproductive History:

Early menstruation (before age 12), late menopause (after age 55), and having the first child at an older age can influence breast cancer risk. More prolonged exposure to oestrogen and progesterone due to these factors may contribute to a higher risk.

  • Lifestyle and Environmental Factors
  1. Diet and Obesity:

A high-fat diet, excessive calorie intake, and obesity are linked to an increased risk of breast cancer. These factors may influence hormonal levels and contribute to cancer progression. Maintaining a healthy weight and adopting a balanced diet can help reduce this risk.

  1. Alcohol Consumption:

Consuming alcohol, even in moderation, is associated with an elevated risk of breast cancer. The risk increases with the amount of alcohol consumed. Limiting alcohol intake or abstaining can be a preventive measure.

  1. Environmental Exposures:

Exposure to environmental toxins, such as certain pesticides and industrial chemicals, is a potential risk factor. However, the exact impact of these exposures on breast cancer risk is still under investigation. Minimising exposure to environmental pollutants is a precautionary step.

  • Other Risk Factors
  1. Radiation Exposure:

Prior exposure to high-dose radiation, such as radiation therapy for other cancers during childhood, can increase the risk of developing breast cancer later in life. Medical professionals take precautions to minimise radiation exposure during treatments.

  1. Previous Breast Cancer:

Individuals previously diagnosed with breast cancer have an increased risk of developing new breast cancer, either in the same or the opposite breast. Close monitoring and follow-up care are essential for early detection and treatment in these cases.

Breast Cancer Prevention Strategies

Lifestyle Modifications

  • Healthy Eating Habits:

Adopting a balanced and nutritious diet can contribute to breast cancer prevention. Focus on consuming various fruits, vegetables, whole grains, and lean proteins. Limiting the intake of processed foods and saturated fats can help maintain a healthy weight and reduce the risk of breast cancer.

  • Regular Exercise:

Regular physical activity has been linked to a lower risk of breast cancer. Aim for at least 150 minutes of moderate or 75 minutes of vigorous-intensity exercise per week. Exercise can help control weight, reduce inflammation, and lower oestrogen levels associated with breast cancer risk.

  • Limiting Alcohol Intake:

Limiting or avoiding alcohol consumption is advisable for breast cancer prevention. Even moderate alcohol consumption has been associated with an increased risk of breast cancer. If you choose to drink, do so in moderation.

Hormone Replacement Therapy (HRT) Considerations:

Women considering hormone replacement therapy (HRT) to manage menopausal symptoms should discuss the potential risks and benefits with their healthcare providers. Prolonged use of combined oestrogen and progesterone HRT has been associated with a slightly increased risk of breast cancer. Providers can help individuals explore alternative treatments or lower-dose options when necessary.

Breastfeeding and Its Protective Effect:

Breastfeeding can offer a protective effect against breast cancer. Women who breastfeed their children have a reduced risk of developing breast cancer. Encouraging and supporting breastfeeding when possible is a preventive measure.

Early Detection through Self-Exams and Screening:

Regular breast self-exams, clinical breast exams by healthcare professionals, and mammograms are essential for early breast cancer detection. Self-exams and clinical exams can help identify any abnormalities, while mammograms use X-rays to detect tumours that may not be palpable. Regular screening can lead to the early diagnosis and treatment of breast cancer, improving outcomes.

Understanding the Role of Genetic Testing

  • BRCA Gene Testing:

Individuals with a family history of breast cancer or known BRCA gene mutations should consider genetic counselling and testing. Understanding genetic risk factors allows for personalised prevention strategies and early detection plans.

Medical Options for High-Risk Individuals

  • Preventive Mastectomy and Oophorectomy:

High-risk individuals, especially those with BRCA gene mutations, may discuss preventive measures such as prophylactic mastectomy (removal of breast tissue) or oophorectomy (removal of ovaries). These surgeries can significantly reduce the risk of breast and ovarian cancers but are decisions made in consultation with healthcare providers based on individual risk profiles and preferences.
