Cervical erosion is permissible for swimming because cervical erosion itself is not considered a disease; it is merely a physiological condition, a normal physiological phenomenon in young women. Cervical erosion is due to high estrogen levels in young people, leading to the proliferation and externalization of columnar epithelium, which is a normal state. It does not affect daily life, including swimming. As long as the water quality in the swimming pool meets health standards and does not lead to infections, normal daily activities can be carried out. Therefore, there is no need to be overly concerned about cervical erosion detected during a physical examination.
