how common is bilateral breast cancer

Release time ：Dec-17,2024

Bilateral breast cancer is relatively infrequent, yet not uncommon. Typically, approximately 2% to 5% of individuals with breast cancer have tumors detected in both breasts simultaneously.

When examining the prevalence of bilateral breast cancer, we should consider a hierarchy from less severe to more severe and from more common to less common factors. Genetic factors significantly contribute to the development of bilateral breast cancer. For instance, individuals with mutations in the BRCA1 and BRCA2 genes are at a notably higher risk of developing bilateral breast cancer compared to the general population. Additionally, environmental and lifestyle factors may also play a role in the occurrence of bilateral breast cancer. Long-term alcohol consumption, obesity, and lack of physical activity are examples of behaviors that could potentially increase the risk of breast cancer. Furthermore, research indicates that breast cancer patients who have received radiation therapy have a relatively elevated risk of developing new primary tumors in the opposite breast.

For those afflicted with bilateral breast cancer, early detection and intervention are paramount. It is therefore advised that women conduct regular self-examinations of their breasts and undergo routine breast examinations by professional medical services. Should any abnormalities be detected, prompt medical consultation is essential, followed by further diagnostic and therapeutic procedures under the direction of a healthcare provider.
