Left-Sided Breast Cancer is More Common, Here’s Why

Table of Contents
left-sided breast cancer

Let’s delve into an interesting facet of breast cancer research – the occurrence of breast cancer on the left side versus the right. While the disparity is slight, understanding the research findings and theories surrounding left-sided breast cancer can offer insights into prevention, treatment, and outcomes.

Research Findings

Recent research, including a study by the National Cancer Institute’s SEER program, suggests that left-sided breast cancer occurs slightly more frequently than on the right side, with a rate of 50.8 percent versus 49.2 percent. This study also hinted at potentially poorer outcomes for left-sided cases, though not conclusively.

Theories Behind the Trend

The reasons for this difference remain speculative, but several theories have been proposed Amy Bremner, M.D., the medical director of breast surgery oncology at MemorialCare Saddleback Medical Center in Laguna Hills, CA  tells Health Central.

According to the SEER study, these include:

  • Earlier detection of left tumors in right-handed women, since it’s easier to do a self-exam with your dominant hand on the opposite side.

  • Larger size of the left breast. A larger breast means more glandular tissue, which slightly increases risk simply because there’s more area to develop cancer in, explains MD Anderson Cancer Center.

  • Preference for right-sided breastfeeding, which may lead to incomplete milk duct drainage in the left side. Research shows that in women who only feed on one side, the risk of breast cancer is higher in the opposite breast.

Researchers also note that biological differences between the left and right sides of the breast may contribute to varying cancer risks.

Outcomes and Survival Rates

While the SEER study reported slightly poorer outcomes for left-sided breast cancer, it’s crucial to emphasize that survival rates only showed a five percent difference.

Factors like tumor grade, hormone status, and treatment responsiveness play a more significant role in determining outcomes. Aggressive cancers can occur in either breast, and personalized treatment plans should be tailored to individual circumstances.

“The fact is that aggressive cancer can happen in either breast, and treatment outcomes have numerous factors at play, not just which side your cancer is on,” Parvin Peddi, M.D., a medical oncologist and the director of breast medical oncology for the Margie Petersen Breast Center at Providence Saint John’s Health Center in Santa Monica, CA tells Health Central.

Treatment Approach

The location of the tumor (left or right) does not alter the assessment or treatment approach. Treatment decisions are primarily based on

factors such as cancer staging, hormone status, and genetic markers. For instance, HER2-positive cancers, more common in left-sided cases, would be addressed accordingly with targeted therapy.

Prevention Strategies

Breast cancer prevention is a critical aspect of women’s health, and understanding how to reduce the risk, particularly on the left side, can empower individuals to take proactive steps.

Here are practical tips considering the unique aspects of breast health for Black women:

1. Culturally Tailored Physical Activity

  • Engage in physical activities that resonate with your cultural preferences and community.
  • Consider group exercises or classes that promote social connections, fostering both physical and mental well-being.

2. Awareness of Genetic Factors

  • Acknowledge the potential influence of genetic factors on breast cancer risk, especially considering that some gene mutations are more prevalent in Black women.
  • Discuss genetic testing options with healthcare providers, particularly if there is a family history of breast cancer.

3. Nutrition and Cultural Diet Considerations

  • Embrace a balanced diet rooted in cultural traditions, incorporating fruits, vegetables, and whole grains.
  • Be mindful of dietary habits and consider consulting with healthcare professionals for culturally sensitive nutritional guidance.

4. Breastfeeding Support

  • Recognize the benefits of breastfeeding for both maternal and infant health.
  • If breastfeeding, aim for balanced feeding on both sides to ensure complete milk duct drainage.
  • Be attentive to any signs of discomfort, and seek guidance from healthcare providers on proper breastfeeding techniques.

5. Advocacy for Equitable Healthcare

  • Advocate for equitable access to healthcare resources and breast cancer screenings within your community.
  • Be proactive in addressing any healthcare disparities and work towards ensuring that Black women have equal opportunities for early detection and quality care.

6. Hormonal Considerations

  • Stay informed about hormonal influences on breast health and discuss with healthcare providers any concerns related to hormonal birth control or hormone replacement therapy.
  • Ensure that healthcare providers are attentive to your individual health needs and provide personalized recommendations.

7. Cultural Competence in Healthcare

  • Seek healthcare providers who demonstrate cultural competence and understanding of the unique health considerations of Black women.
  • Foster open communication with healthcare professionals to ensure that your health concerns are addressed comprehensively.

8. Community Support and Education

  • Participate in community-based health initiatives and educational programs that focus on breast health.
  • Share information within your community to raise awareness and promote proactive health measures.

9. Regular Health Check-Ups

  • Prioritize regular health check-ups, screenings, and mammograms as recommended.
  • Be an advocate for your health by actively participating in discussions with healthcare providers about preventive measures and screenings.

10. Tobacco and Alcohol Avoidance

  • Quit smoking and steer clear of tobacco products to minimize cancer risks.
  • Limit alcohol consumption or avoid it altogether, as excessive alcohol intake has been linked to an increased risk of breast cancer.

11. Maintain a Healthy Weight

  • Strive for a body mass index (BMI) within the recommended range.
  • Achieve and maintain a healthy weight through a combination of diet and regular exercise.

Empower yourself with knowledge, advocate for equitable healthcare, and take culturally informed steps towards breast health and overall well-being. Remember that individual health considerations vary, so consulting with healthcare professionals for personalized advice is crucial. Together, let’s foster a culture of proactive health within the diverse tapestry of Black women’s communities.
