Patient's question:
After retracting the foreskin, there are some small bumps inside, red and white, patchy, and they have been there for two years without pain or discomfort. But they look unpleasant. What should I do?Doctor's answer:
Due to excessive foreskin, some of the sebum excreted by the foreskin accumulates in the gap between the foreskin and the glans. At the same time, urine also enters this gap and reacts chemically with the sebum, forming what you described as smegma. Over time, it hardens. Smegma is a chemical carcinogen with strong carcinogenic effects, primarily stimulating the glans directly to cause penile cancer, leading to frequent inflammation of the foreskin and glans. Long-term inflammation can cause the degeneration and further deterioration of local tissue cells in the penis, creating a malignant environment at the glans and leading to pre-cancerous lesions of penile cancer. If the glans suddenly develops a painless, itchy, and continuously growing lump that also purulents, it is likely penile cancer.
