A cervical biopsy 20 days can be douched, but try to choose a shower, avoid the basin bath, should also try to avoid non-essential vaginal douching. After 20 days of cervical biopsy, the wound can usually be completely healed, and at this time, there is usually no longer bleeding, oozing and other manifestations, so douching can be carried out. However, when douching, it is best to choose a shower, because the flowing water in the shower can take away the bacteria, and the running water in the shower room will not enter the vagina, which can minimize the probability of infection of the cervical biopsy wound. When performing douching, try to avoid taking a basin bath, although the cervical biopsy wound has basically completely healed, but the local immunity is still weak, when taking a basin bath, if the water is contaminated there is still a possibility of contamination of the wound, resulting in local inflammation or vaginal flora imbalance.
