After cervical cancer screening, most of the women will experience a small amount of vaginal bleeding or blood color in the leukorrhea. The main reason is that the small brush for taking specimen will enter into the cervical canal, and the mucous membrane in the cervical canal is relatively thin, when brushing the specimen, it will lead to the breakage of local mucous membrane, causing the rupture of capillaries, which will lead to a small amount of bleeding in clinic. Therefore, it is recommended that after cervical cancer screening: 1. no sexual intercourse for one week. 2. no sitz bath for one week, only shower for bathing, and keep the vulva clean, so as to avoid the possibility of infection of the local trauma. It is recommended that women should do cervical cancer screening once a year even if they don’t have any discomfort, so as to know whether there is any abnormality in the cervix locally, and to deal with the abnormality in time when it is found.
