In cases where the cancer is found on the foreskin, circumcision can often cure the cancer. A circumcision operation removes the foreskin and nearby skin, in this case, to reduce the risk of cancer returning.
Circumcisions may also be done prior to radiation therapy treatment. Radiation can cause swelling and constriction to the foreskin if not removed.
A simple excision removes the tumor with a surgical knife, along with surrounding skin in the area.
In microscopically controlled surgery, or Mohs surgery, the surgeon removes a layer of skin that the tumor may have invaded and then checks the sample under a microscope. If the layer contains cancer, another layer is removed and examined. This process continues until the skin samples are cancer-free.
This is a highly specialized technique only used by doctors who have been trained in this specific type of surgery. It can be used for carcinoma in situ (CIS), where the cancer is in only the top layers of the skin, and for some early-stage cancers that have not grown deeply into the penis
Men with cancer that has grown deep within the penis (stage T2 or higher) are likely to need nearby lymph nodes in the groin area removed to check for cancer spread. This is called an inguinal lymph node dissection.
