Pressing the glans has a small bump, which may be caused by glansitis, condyloma acuminatum, sebaceous cysts and other reasons. 1. glansitis: the glans is attacked by pathogenic bacteria, which can cause a local inflammatory reaction and a small pimple. 2. Condyloma acuminatum: In high-risk sexual behavior, the glans skin is infected by the human papilloma virus, which can appear as a papillary or cauliflower-shaped bump. 3. Sebaceous cysts: If the sebaceous gland secretions cannot be discharged normally from the gland opening, they can accumulate under the skin and appear in the shape of a small bump. It is recommended that those who have a small bump when pressing the glans go to the hospital in time to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
