Prolonged foreskin and phimosis are both congenital developmental abnormalities. "Prolonged prepuce refers to the prepuce covering the head of the penis. Only when the skin is turned up by hand, or when the penis is fully erect, can the penis's head and coronal sulcus be exposed.". Phimosis refers to the fact that the opening of the foreskin is too small and tight to turn up or move up without exposing the glans and coronal groove. If there is a long foreskin and phimosis, and the penis cannot be exposed, it can cause various complications. Such as: prepuce penis inflammation, chronic urethritis, cystitis, pyelonephritis, penis cancer, and so on.
Just as the skin of various parts of the human body secretes sebum, the sebaceous glands of the foreskin also secrete sebum. "Because the foreskin is too long or cannot be turned up during phimosis, this sebum accumulates in the space between the inner surface of the foreskin and the penis head, and urine also seeps into this space, reacting chemically with this sebum, turning it into foreskin scale and producing a strange odor.". The long-term accumulation of foreskin dirt can become hard lumps, making people mistakenly believe that it is a tumor. Foreskin scale is a chemical carcinogen, and many experiments have confirmed that it has a strong carcinogenic effect. If the foreskin of a horse is scaled into the body of a seed mouse, it can cause malignant tumors in the skin. Inoculating mice with human foreskin scales can also induce uterine head cancer in female mice.
Modern medicine has confirmed that the specific hazards of foreskin scaling include:
1. Direct stimulation of the head of the penis induces penile cancer.
2. Causes frequent inflammation of the foreskin and penis head, and long-term inflammatory stimulation can cause degeneration and deterioration of local tissue cells of the penis.
3. Creating a harsh environment on the head of the penis can induce precancerous lesions in many penile cancers, such as: penis angle, papilloma of the penis, condyloma acuminatum, leukoplakia of the penis, proliferative erythema of the penis, etc. Such lesions are easily converted to penile cancer.
Under the "prelude" of long foreskin and phimosis, and behind the "main melody" of foreskin scaling, there will be a "variation climax" of penis cancer, which is a terrible "climax" because penis cancer is a disease that can take lives.
According to epidemiological investigations, more than 90% of penile cancer is caused by excessive foreskin or foreskin scaling caused by phimosis.
