Penile Cancer Treatment (PDQ®): Treatment - Patient Information [NCI]
General Information About Penile Cancer
Penile cancer is a type of cancer that forms in the tissues of the penis.
The penis is a rod-shaped male reproductive organ that passes sperm and urine from the body. It contains two types of erectile tissue (spongy tissue with blood vessels that fill with blood to make an erection):
- Corpora cavernosa are the two columns of erectile tissue that form most of the penis.
- Corpus spongiosum is the single column of erectile tissue that forms a small portion of the penis. The corpus spongiosum surrounds the urethra (the tube through which urine and sperm pass from the body).
The erectile tissue is wrapped in connective tissue and covered with skin. The glans (head of the penis) is covered with loose skin called the foreskin. 
Anatomy of the penis. The parts of the penis are the base, shaft, glans, and foreskin. The tissues that make up the penis include the dorsal nerve, blood vessels, connective tissue, and erectile tissue (corpus cavernosum and corpus spongiosum). The urethra passes from the bladder to the tip of the penis.
Human papillomavirus infection may increase the risk of developing penile cancer.
A risk factor is anything that increases the chance of getting a disease. Some risk factors for penile cancer, like smoking, can be changed. However, risk factors also include things you cannot change, like your genetics, getting older, and your family history. Learning about risk factors for penile cancer can help you make changes that might lower your risk of getting it.
Risk factors for penile cancer include:
- Being uncircumcised. Circumcision may help prevent infection with the human papillomavirus (HPV). A circumcision is an operation in which the doctor removes part or all of the foreskin from the penis. Many boys are circumcised shortly after birth. Men who were not circumcised at birth may have a higher risk of developing penile cancer.
- Being 60 years or older.
- Having phimosis (a condition in which the foreskin of the penis cannot be pulled back over the glans).
- Having poor personal hygiene.
- Having many sexual partners.
- Using tobacco products.
Signs of penile cancer include sores, discharge, and bleeding.
These and other signs may be caused by penile cancer or by other conditions. Check with your doctor if you have:
- redness, irritation, or a sore on the penis
- a lump on the penis
Tests that examine the penis are used to diagnose penile cancer.
In addition to asking about your personal and family health history and doing a physical exam, your doctor may perform the following tests and procedures:
- Physical exam of the penis is an exam in which the doctor checks the penis for signs of disease, such as lumps or anything else that seems unusual.
- Biopsy is the removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue sample is removed during one of the following procedures:
- Incisional biopsy is the removal of part of a lump or a sample of tissue that doesn't look normal.
- Excisional biopsy is the removal of an entire lump or area of tissue that doesn't look normal.
After penile cancer has been diagnosed, tests are done to find out if cancer cells have spread within the penis or to other parts of the body.
The process used to find out if cancer has spread within the penis or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment.
The following tests and procedures may be used in the staging process:
- CT scan (CAT scan) uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body, such as the pelvis. The pictures are taken from different angles and are used to create 3-D views of tissues and organs. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- PET scan (positron emission tomography scan) uses a small amount of radioactive sugar (also called glucose) that is injected into a vein. Then a scanner rotates around the body to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. When this procedure is done at the same time as a CT scan, it is called a PET/CT scan.
- MRI (magnetic resonance imaging) is a procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Ultrasound exam is a procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
- Chest x-ray is an x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
- Biopsy is the removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue sample is removed during one of the following procedures:
- Sentinel lymph node biopsy is the removal of the sentinel lymph node during surgery. The sentinel lymph node is the first lymph node in a group of lymph nodes to receive lymphatic drainage from the primary tumor. It is the first lymph node the cancer is likely to spread to from the primary tumor. A radioactive substance and/or blue dye is injected near the tumor. The substance or dye flows through the lymph ducts to the lymph nodes. The first lymph node to receive the substance or dye is removed. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are not found, it may not be necessary to remove more lymph nodes. Sometimes, a sentinel lymph node is found in more than one group of nodes.
- Lymph node dissection is a procedure to remove one or more lymph nodes in the groin during surgery. A sample of tissue is checked under a microscope for signs of cancer. This procedure is also called a lymphadenectomy.
Some people decide to get a second opinion.
You may want to get a second opinion to confirm your penile cancer diagnosis and treatment plan. If you seek a second opinion, you will need to get medical test results and reports from the first doctor to share with the second doctor. The second doctor will review the pathology report, slides, and scans. They may agree with the first doctor, suggest changes or another treatment approach, or provide more information about your cancer.
Learn more about choosing a doctor and getting a second opinion at Finding Cancer Care. You can contact NCI's Cancer Information Service via chat, email, or phone (both in English and Spanish) for help finding a doctor, hospital, or getting a second opinion. For questions you might want to ask at your appointments, visit Questions to Ask Your Doctor About Cancer.
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis and treatment options depend on:
- the stage of the cancer
- the location and size of the tumor
- whether the cancer has just been diagnosed or has recurred (come back)
Treatment Option Overview
There are different types of treatment for people with penile cancer.
Different types of treatments are available for penile cancer. You and your cancer care team will work together to decide your treatment plan, which may include more than one type of treatment. Many factors will be considered, such as the stage of the cancer, your overall health, and your preferences. Your plan will include information about your cancer, the goals of treatment, your treatment options and the possible side effects, and the expected length of treatment.
Talking with your cancer care team before treatment begins about what to expect will be helpful. You'll want to learn what you need to do before treatment begins, how you'll feel while going through it, and what kind of help you will need. To learn more, visit Questions to Ask Your Doctor About Treatment.
The following types of treatment are used:
Surgery
Surgery is the most common treatment for all stages of penile cancer. A doctor may remove the cancer using one of the following operations:
- Mohs microsurgery: A procedure in which the tumor is cut from the skin in thin layers. During the surgery, the edges of the tumor and each layer of tumor removed are viewed through a microscope to check for cancer cells. Layers continue to be removed until no more cancer cells are seen. This type of surgery removes as little normal tissue as possible and is often used to remove cancer on the skin. It is also called Mohs surgery.
Mohs surgery. A surgical procedure to remove a visible lesion on the skin in several steps. First, a thin layer of cancerous tissue is removed. Then, a second thin layer of tissue is removed and viewed under a microscope to check for cancer cells. More layers are removed one at a time until the tissue viewed under a microscope shows no remaining cancer. This type of surgery is used to remove as little normal tissue as possible. - Laser surgery: A surgical procedure that uses a laser beam (a narrow beam of intense light) as a knife to make bloodless cuts in tissue or to remove a surface lesion such as a tumor.
- Cryosurgery: A treatment that uses an instrument to freeze and destroy abnormal tissue. This type of treatment is also called cryotherapy.
- Circumcision: Surgery to remove part or all of the foreskin of the penis.
- Wide local excision: Surgery to remove only the cancer and some normal tissue around it.
- Amputation of the penis: Surgery to remove part or all of the penis. If part of the penis is removed, it is a partial penectomy. If all of the penis is removed, it is a total penectomy.
Lymph nodes in the groin may be taken out during surgery.
After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:
- External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer.
- Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.
The way the radiation therapy is given depends on the type and stage of the cancer being treated. External and internal radiation therapy are used to treat penile cancer.
Learn more about Radiation Therapy to Treat Cancer and Radiation Therapy Side Effects.
Chemotherapy
Chemotherapy (also called chemo) uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
Topical chemotherapy is placed directly onto the skin, where it mainly affects cancer cells in those areas. Topical chemotherapy, such as fluorouracil may be used to treat stage 0 penile cancer.
Systemic chemotherapy is when chemotherapy drugs are taken by mouth or injected into a vein or muscle. When given this way, the drugs enter the bloodstream and can reach cancer cells throughout the body. Systemic chemotherapy may be used if the cancer is too large to be removed by surgery or has spread to the lymph nodes or other parts of the body.

Immunotherapy
Immunotherapy helps a person's immune system fight cancer.
Immunotherapy drugs used to treat penile cancer include:
- topical imiquimod

New types of treatment are being tested in clinical trials.
A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. For some patients, taking part in a clinical trial may be an option.
Use our clinical trial search to find NCI-supported cancer clinical trials that are accepting patients. You can search for trials based on the type of cancer, the age of the patient, and where the trials are being done. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.
To learn more about clinical trials, see Clinical Trials Information for Patients and Caregivers.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.
Radiosensitizers
Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers helps kill more tumor cells.
Sentinel lymph node biopsy followed by surgery
Sentinel lymph node biopsy is the removal of the sentinel lymph node during surgery. The sentinel lymph node is the first lymph node in a group of lymph nodes to receive lymphatic drainage from the primary tumor. It is the first lymph node the cancer is likely to spread to from the primary tumor. A radioactive substance and/or blue dye is injected near the tumor. The substance or dye flows through the lymph ducts to the lymph nodes. The first lymph node to receive the substance or dye is removed. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are not found, it may not be necessary to remove more lymph nodes. Sometimes, a sentinel lymph node is found in more than one group of nodes. After the sentinel lymph node biopsy, the surgeon removes the cancer.
Treatment for penile cancer may cause side effects.
For information about side effects caused by treatment for cancer, visit our Side Effects page.
Follow-up care may be needed.
As you go through treatment, you will have follow-up tests or check-ups. Some tests that were done to diagnose or stage the cancer may be repeated to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back).
