Bleeding during intercourse is a common occurrence for many women of childbearing age. Bleeding during intercourse is medically known as contact bleeding and requires vigilance. In many clinical conditions, including cervical lesions, cervical cancer, and precancerous lesions of the cervix, the earliest detectable symptom and reason for patient consultation is contact bleeding. It is important to pay attention to this situation and seek timely medical attention to rule out the possibility of cervical lesions. However, there is no need to panic, not all contact bleeding is cervical cancer. Benign cervical lesions, such as cervicitis and cervical polyps, can cause contact bleeding. If it is not easy to determine the cause, it is recommended to go to the hospital to seek medical help in time.
