Mrs. Liu, who has passed the age of forty, felt as if there was a depression on the skin of the lateral side of her left breast and she could feel a small lump underneath, so she went for a check-up and was diagnosed with breast cancer.
The dimple that appears on the breast is vividly called the "dimple sign" because of its resemblance to a酒窝 (dimple). This occurs due to the formation of a round or oval painless single small lump inside the breast in the early stages of breast cancer.
