Ms. Wu, 35 years old, recently always felt a隐隐 pain in her breasts. Her first reaction was, "I hope I didn't get breast cancer." This terrible thought completely restlessness her.

She had already prepared for the worst, but in the end, the expert surprisingly told her, "Don't worry too much, the breast pain is caused by cervical spondylosis."
