What is cancer of the penis?
Cancer of the penis, a rare kind of cancer in the United States, is a disease in which cancer (malignant) cells are found on the skin and in the tissues of the penis.
Men who are not circumcised at birth may have a higher risk for getting cancer of the penis. A circumcision is an operation in which the doctor takes away part or all of the foreskin from the penis. The foreskin is the skin that covers the tip of the penis. A circumcision is done on many baby boys before they go home from the hospital.
A doctor should be seen if there are any of the following problems: growths or sores on the penis, any unusual liquid coming from the penis (abnormal discharge), or bleeding.
If there are symptoms of cancer, the doctor will examine the penis and feel for any lumps. If the penis doesn’t look normal or if the doctor feels any lumps, a small sample of tissue (called a biopsy) will be cut from the penis and looked at under a microscope to see if there are any cancer cells.
The prognosis (chance of recovery) and choice of treatment depend on the stage of the cancer (whether it is just in the penis or has spread to other places), and the patient’s general state of health.
Stages of cancer of the penis
Once cancer of the penis is found, more tests will be done to find out if the cancer has spread from the penis to other parts of the body (staging). It is important to know the stage of the disease in order to plan treatment. The following stages are used for cancer of the penis:
Cancer is found only on the surface of the skin of the penis. Stage 0 cancer is also called carcinoma in situ.
Cancer has spread to connective tissue just under the skin of the penis.
Cancer has spread to either:
Cancer has spread to either:
Cancer has spread:
to tissues next to the penis and may have spread to lymph nodes in the groin or pelvis; or
anywhere in or near the penis and in one or more lymph nodes deep in the pelvis or groin; or
to distant parts of the body.
Recurrent disease means that the cancer has come back (recurred) after it has been treated. It may come back in the same area or in another place.
Treatment Option Overview
How cancer of the penis is treated
There are treatments for all patients with cancer of the penis. Four kinds of treatment are used:
Surgery is the most common treatment of all stages of cancer of the penis. A doctor may take out the cancer using one of the following operations:
Wide local excision takes out only the cancer and some normal tissue on either side.
Mohs microsurgery is an operation that removes the cancer and as little normal tissue as possible. During this surgery, the doctor uses a microscope to look at the cancerous area to make sure all the cancer cells are removed.
Laser surgery uses a narrow beam of light to remove cancer cells.
Cryosurgery uses an instrument to freeze and destroy abnormal tissue, such as carcinoma in situ. This type of treatment is also called cryotherapy.
Circumcision is an operation that removes the foreskin.
Amputation of the penis is an operation that takes out all or part of the penis. It is the most common and most effective treatment of cancer of the penis. In a partial penectomy, part of the penis is taken out. In a total penectomy, the whole penis is removed. Lymph nodes in the groin may be taken out during surgery.
Radiation therapy uses x-rays or other high-energy rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation) or from putting materials that contain radiation through thin plastic tubes into the area where the cancer cells are (internal radiation). Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more tumor cells. Radiation may be used alone or after surgery.
Chemotherapy uses drugs to kill cancer cells. Fluorouracil cream (a topical anticancer drug) is sometimes used on the skin of the penis for very small surface cancers. Chemotherapy may also be given by pill or by a needle in a vein. When chemotherapy is given in this way, it is called a systemic treatment because the drugs enter the bloodstream, travel through the body, and can kill cancer cells outside the penis.
Biological therapy tries to get the body to fight cancer. It uses materials made by the body or made in a laboratory to boost, direct, or restore the body’s natural defenses against disease. Biological treatment is sometimes called biological response modifier (BRM) therapy. Imiquimod is a topical biological response modifier that may be used for small cancers on the surface of the penis.
Treatment by stage
Treatment of cancer of the penis depends on the stage of the disease, the type of disease, and the patient’s age and overall condition.
Standard treatment may be considered because of its effectiveness in patients in past studies, or participation in a clinical trial may be considered. Not all patients are cured with standard therapy and some standard treatments may have unwanted side effects. For these reasons, clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. Clinical trials are ongoing in many parts of the country for most stages of cancer of the penis. Information about ongoing trials is available from the NCI Web site. To learn more about clinical trials, call the Cancer Information Service at 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615.
Stage 0 Penile Cancer
Treatment of stage 0 penile cancer may be one of the following:
Stage I Penile Cancer
If the cancer is only in the foreskin, treatment will probably be wide local excision and circumcision.
If the tumor begins in the glans, treatment may include:
Treatment of stage I penile cancer may also be a clinical trial of laser therapy.
Stage II Penile Cancer
Treatment of stage II penile cancer may include the following:
Stage III Penile Cancer
Treatment of stage III penile cancer may include the following:
Stage IV Penile Cancer
Treatment of stage IV penile cancer is usually palliative (to relieve symptoms and improve the quality of life). Treatment may include the following:
Recurrent Penile Cancer
If the cancer has come back (recurred), treatment may include the following:

Web sites and Organizations
The NCI Web site provides online access to information on cancer, clinical trials, and other Web sites and organizations that offer support and resources for cancer patients and their families. There are also many other places where people can get materials and information about cancer treatment and services. Local hospitals may have information on local and regional agencies that offer information about finances, getting to and from treatment, receiving care at home, and dealing with problems associated with cancer treatment.
The NCI has booklets and other materials for patients, health professionals, and the public. These publications discuss types of cancer, methods of cancer treatment, coping with cancer, and clinical trials. Some publications provide information on tests for cancer, cancer causes and prevention, cancer statistics, and NCI research activities. NCI materials on these and other topics may be ordered online or printed directly from the NCI Publications Locator. These materials can also be ordered by telephone from the Cancer Information Service toll-free at 1-800-4-CANCER (1-800-422-6237), TTY at 1-800-332-8615.
The NCI's LiveHelp service, a program available on several of the Institute's Web sites, provides Internet users with the ability to chat online with an Information Specialist.

PDQ is a comprehensive cancer database available on NCI's Web site.
PDQ is the National Cancer Institute's (NCI's) comprehensive cancer information database. Most of the information contained in PDQ is available online at NCI's Web site. PDQ is provided as a service of the NCI. The NCI is part of the National Institutes of Health, the federal government's focal point for biomedical research.
PDQ contains cancer information summaries.
The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries are available in two versions. The health professional versions provide detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions provide current and accurate cancer information.
The PDQ cancer information summaries are developed by cancer experts and reviewed regularly.
Editorial Boards made up of experts in oncology and related specialties are responsible for writing and maintaining the cancer information summaries. The summaries are reviewed regularly and changes are made as new information becomes available. The date on each summary ("Date Last Modified") indicates the time of the most recent change.
PDQ also contains information on clinical trials.
Before starting treatment, patients may want to think about taking part in a clinical trial. A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about new treatments, the risks involved, and how well they do or do not work. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard."
Listings of clinical trials are included in PDQ and are available online at NCI's Web site. Descriptions of the trials are available in health professional and patient versions. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615.
