Yes, too long foreskin will cause many adverse effects and complications. It is very important to choose the best time for circumcision as soon as possible. Because the foreskin is too long or phimosis will hinder the development of genitals, resulting in genital dysplasia and short genitals, foreskin surgery can be done at the age of 8- 10. Circumcision can reduce the incidence of balanitis prepuce, just like appendectomy. However, scale is not a carcinogen, because the human body itself will not produce substances harmful to itself. Scale is only the normal secretion of human body, and lysozyme in scale has obvious bactericidal effect. But not cleaning for a long time may cause inflammation.

My very best wishes to your health
