Breast cancer is a malignant tumor that develops in breast tissue, and it is one of the more common cancers in women. Surgical and reconstruction techniques continue to advance, and outcomes are generally good when the cancer is found early. If a breast screening shows an abnormal result, or if you notice a lump or a change in the skin, please see a medical specialist.

Diabetic retinopathy is a condition in which prolonged high blood sugar damages the tiny blood vessels and nerve tissue of the retina, the light-sensing layer inside the eye. About 15 to 30% of diabetic patients in Korea have this condition, and it is important to have an annual eye exam even without symptoms. Diabetic retinopathy is one of the three leading causes of blindness in Korea, so early detection and appropriate treatment are essential to protecting your vision.

If you have a voice change lasting more than 6 weeks, a mouth sore that doesn't heal after 3 weeks, or a lump in the neck, please see an ENT (ear, nose, and throat) specialist.

If these symptoms are suspected, please see a medical specialist right away.
