The Connection Between Breast Cancer and Eye Health
October is Breast Cancer Awareness Month, a time to educate ourselves about the challenges breast cancer patients face and how we can support them. Did you know that 1 in 8 women will be diagnosed with breast cancer in their lifetime? That’s about 12.5% of women! In 2023, an estimated 297,790 new cases of invasive breast cancer were diagnosed in the U.S., making it the most common cancer among women.
Understanding Choroidal Metastases
One lesser-known aspect of breast cancer is its potential to spread to the eyes. The choroid, a layer of tissue in the middle of the eye filled with blood vessels, is the most common site for cancerous cells from other parts of the body to form tumors, known as choroidal metastases. In women, breast cancer is responsible for 40-47% of these tumors.
While some individuals may experience symptoms like blurred vision, many people with choroidal metastases have no symptoms at all. This makes regular eye exams crucial—not just for preserving your vision but also for your overall health. In fact, around 25% of patients with eye metastases may not have a known history of cancer until they receive a diagnosis elsewhere in their bodies, often breast cancer.
Why Eye Exams Matter
During an eye exam, your optometrist can use advanced techniques to check for signs of cancer. High-definition retinal imaging along with dilated eye exams, can reveal abnormalities in the retina and optic nerve that might indicate metastasis. Tumors developing in and around the eyes, which are often painless and may not cause symptoms until later stages.
The eyes are often referred to as the “windows to your health” because they provide a unique view of the body’s blood vessels and nerves without needing X-rays or surgery. This means that eye exams can be an essential part of your health check-up, especially if you have risk factors for breast cancer.
Recognizing Risk Factors
While many believe breast cancer is primarily inherited, only about 5-10% of cases are linked to genetic factors. Less than 15% of diagnosed women have a family member with breast cancer. However, having a first-degree relative, like a mother or sister, can nearly double your risk.
It’s essential to discuss your family history and any concerns with your doctor to determine the best approach for breast cancer screenings. Most insurance plans cover mammograms starting at age 40.
The Impact of Cancer Treatment on Eye Health
If you are diagnosed with breast cancer, be aware that treatments like chemotherapy, radiation, and hormone therapy can lead to eye-related side effects. Common issues include red, itchy, or dry eyes, as well as watery eyes and blurry vision. If you experience any of these symptoms, please consult your eye doctor. Regular follow-ups during and after treatment are crucial for keeping your eyes comfortable and healthy.
