The dangers that may arise from circumcision are: 1. local pain, erosion or exudation, resulting in a decrease in quality of life due to pain, erosion or exudation. 2. repeated circumcision can lead to foreskin stenosis, which can result in pathological prepuce, painful erection or difficulty in urination. 3. secondary urinary tract infections can cause frequent urination, urinary urgency and painful urination, which can seriously affect the quality of life. This can lead to a higher probability of malignant tumors in the local skin, i.e. a higher probability of penile cancer. 5. It can cause acute complications such as local cracking of the foreskin, or foreskin impaction.
