Is a 30mm Cervical Canal Normal?

The cervical canal is a part of the cervix, belonging to the reproductive system and a unique structure in females. It is mainly located above the vagina and within the cervix at the lower part of the uterus. When projected onto the body surface, it is approximately positioned just behind the pubic bone. The cervical canal has a spindle-shaped tubular appearance, thicker at the top and thinner at the bottom, with a color similar to normal skin mucosa.

The primary function of the cervical canal in the body is to protect and assist in reproduction. The length of the cervical canal in non-pregnant women ranges from 25mm to 30mm, and it is longer in pregnant women. When the cervical canal measures 30mm, it falls within the normal range, indicating it is normal. Since the cervix connects to the outside world through the vagina, it is prone to diseases such as cervical ectropion, acute cervicitis, chronic cervicitis, and cervical cancer. These can have an impact on health, so it is important to maintain good personal hygiene and seek timely treatment in case of any abnormalities.
