Breast Cancer Prevention: Expert Insights

Breast cancer remains one of the most common cancers affecting women worldwide¹. While genetic factors can play a role, lifestyle choices and preventive measures are crucial in reducing the risk². 

In this blog post, we will explore the importance of diet, exercise, and other lifestyle choices in breast cancer prevention, as well as the impact of alcohol consumption on breast cancer risk with Prof. Paolo Veronesi and Dr. Martin Colombo, experts in breast cancer and breast reconstruction.

Lifestyle changes to reduce breast cancer risk

When it comes to breast cancer prevention, lifestyle choices play a crucial role. Prof. Paolo Veronesi, Director of the Breast Program and Director of Breast Surgical Division at the European Institute of Oncology, and Professor of Surgery at the University of Milan, shares valuable insights on this topic:

“Adopting a healthy lifestyle can significantly reduce the risk of breast cancer. Regular physical activity and maintaining a healthy weight are crucial. Regular screenings and self-exams are essential for early detection. Breastfeeding also provides an additional protective effect when practiced at a young age and for an extended period.”

The role of diet in breast cancer prevention

Diet is a significant factor in breast cancer prevention. Prof. Veronesi highlights the importance of dietary choices:

“Studies show that a diet rich in fruits, vegetables, and whole grains can lower the risk of breast cancer. Reducing red and processed meat consumption is also recommended, as high intake has been linked to increased breast cancer risk. Additionally, avoiding alcohol consumption and smoking is crucial since alcohol has been shown to raise estrogen levels and damage the DNA, contributing to tumour development. Overall, a balanced diet, limiting sugar intake and emphasizing plant-based foods can significantly contribute to breast cancer prevention.”
Dr. Martin Colombo a renonwned plastic and reconstructive surgeon from Argentina provides further insight into the connection between alcohol and breast cancer:

“The International Agency for Research on Cancer (IARC) has classified alcohol as a Group 1 carcinogen, indicating that there is convincing evidence to show that it can cause cancer in humans. Indeed, alcohol consumption is a major risk factor for multiple cancers including breast. Compared with other organs, the breast appears to be more susceptible to the carcinogenic effects of alcohol. Being overweight or obese after menopause, drinking alcohol and taking menopausal hormone therapy are all linked to an increased risk of breast cancer. A pooled analysis of data from 53 studies found for each alcoholic drink consumed per day, the relative risk of breast cancer increased by about 7%. Women who had 2-3 alcoholic drinks per day had a 20% higher risk of breast cancer than women who didn’t drink alcohol.”

Benefits of regular exercise in breast cancer prevention

Physical activity is another key factor in preventing breast cancer. Prof. Veronesi explains the benefits of regular exercise:
“Engaging in physical activity helps maintain a healthy weight, which is linked to lower estrogen levels and reduced cancer risk. Exercise also boosts the immune system and improves insulin sensitivity, both of which contribute to cancer prevention. Studies have shown that women who engage in moderate to vigorous physical activity for at least 150 minutes per week have a significantly lower risk of developing breast cancer. Overall, incorporating regular exercise into one’s lifestyle is an effective strategy for breast cancer prevention.”

Conclusion

In conclusion, making informed lifestyle choices can reduce the risk of breast cancer. By adopting a healthy diet, engaging in regular physical activity, avoiding alcohol and smoking, and staying vigilant with regular screenings, women can take proactive steps toward breast cancer prevention. Additionally, breastfeeding and maintaining a healthy weight further contribute to lowering the risk.
