In recent years, interest in understanding breast cancer has become more widespread than ever before. The studies conducted to understand this significant health problem have found unbelievable evidence.
Research indicates that the left breast is 5% to 10% more likely to develop cancer; however, it’s unsure why. In this blog, let’s discuss all the suspected reasons why cancer is more common in the left breast and what you should know.
Reasons Why Left Breast Cancer Is More Prevalent
Even though the reason why the left breast is more likely to develop cancer is not entirely understood. There are some reasons why researchers believe this phenomenon occurs.
One of these reasons is that the left breast is usually larger in volume and has more glandular tissue than the right. Researchers suggest that left breasts might be at risk for developing cancer due to the increased tissue density.
Additionally, hormones have a significant impact on the likelihood of developing breast cancer. Some studies suggest that the two breasts have different hormonal exposures, and because of the variation in blood flow or lymphatic drainage, hormones affect each breast differently.
Genetics also plays a role in developing breast cancer. Hereditary factors also decide the difference between each breast because of anatomical and physiological variations. This is also a reason why researchers believe that breast cancer is more prevalent in the left breast. However, the exact reason for this has not yet been determined.
Is Left Breast Cancer Deadlier?
Trying to determine if cancer in the left breast is deadlier than the right breast is difficult as there are many factors at play. Generally, survival rates are not impacted by which breast is affected.
Some studies suggest that tumors on the left side may lead to lower survival rates as they may be diagnosed at later stages due to their location. Regardless of which breast is likely to be more cancerous, early detection is what improves outcomes.
Early Detection Can Save Lives
While some studies do suggest that left breasts are more likely to get cancer, it’s essential not to overlook any signs on the right side. Signs of cancer can be easily missed, so you must keep looking out for them.
You can help early cancer detection by doing frequent self-examinations. Be familiar with your breasts, and be alert if you see changes. However, since self-examinations can’t always be reliable, mammograms are recommended. They involve thorough X-ray exams that detect tumors that self-examinations can easily miss.
Research indicated that regular screenings can detect cancers at their earlier stages, which facilitates effective treatment.
Takeaway
To summarize, the reason why breast cancer is prevalent in the left breast more than in the right breast isn’t known. However, the bottom line is that early detection is key to preventing complications and fatalities.
