Penile cancer
What is penile cancer?
Penile cancer is a rare type of cancer that develops in the tissues of the penis. It typically originates in the skin or cells that line the inner and outer surfaces of the penis. Like other forms of cancer, penile cancer occurs when cells begin to grow and multiply uncontrollably, forming a tumor. Penile cancer can potentially invade nearby tissues and, in later stages, spread to lymph nodes and other parts of the body.
Risk factors
The development of penile cancer can be influenced by various risk factors. While the presence of these risk factors doesn't guarantee that an individual will develop the disease, they can increase the likelihood. Common risk factors associated with penile cancer include:
-
Human Papillomavirus (HPV) Infection: Certain strains of HPV are known to increase the risk of penile cancer. HPV is a sexually transmitted infection, and individuals with a history of genital warts or HPV-related diseases may have a higher risk. HPV vaccination can help reduce the risk.
-
Smoking: Smoking is a significant risk factor for penile cancer. The harmful chemicals in tobacco smoke can accumulate in the genital area and potentially lead to cellular changes that increase the risk of cancer.
-
Lack of Circumcision: Uncircumcised men may have a slightly higher risk of penile cancer compared to circumcised men. Proper hygiene in uncircumcised individuals can reduce this risk.
-
Phimosis: Phimosis is a condition in which the foreskin cannot be pulled back to expose the glans (head) of the penis. This condition can lead to inflammation and irritation, potentially increasing the risk of penile cancer.
-
Poor Hygiene: Inadequate penile hygiene, which can lead to the accumulation of smegma (a mixture of dead skin cells and body oils) under the foreskin, may contribute to the risk of penile cancer.
-
Age: Penile cancer is more common in older men, with the highest incidence in those over 60 years old.
-
Personal and Family History: A personal history of penile cancer or a family history of the disease may be associated with an increased risk.
It's essential to understand these risk factors and take preventive measures where possible. For example, practicing safe sex to reduce the risk of HPV infection and quitting smoking can help lower the risk of penile cancer. Maintaining proper penile hygiene and considering circumcision (although this is a personal choice) can also contribute to reducing the risk. Regular medical check-ups and early detection are important to facilitate prompt diagnosis and treatment if penile cancer does develop, potentially improving the chances of a favorable outcome.
Causes
The exact causes of penile cancer are not always clear, but it is likely the result of a combination of genetic, environmental, and lifestyle factors. Some of the known and potential factors that may contribute to the development of penile cancer include:
-
Human Papillomavirus (HPV) Infection: Certain strains of HPV have been linked to an increased risk of penile cancer. HPV is a sexually transmitted virus, and persistent infection with high-risk HPV types is a significant risk factor. HPV vaccination can help reduce the risk of HPV-related penile cancer.
-
Tobacco Use: Smoking is a significant risk factor for penile cancer. The harmful chemicals in tobacco smoke can accumulate in the genital area and potentially lead to cellular changes that increase the risk of cancer.
-
Lack of Circumcision: Uncircumcised men may have a slightly higher risk of penile cancer compared to circumcised men. Proper hygiene in uncircumcised individuals can reduce this risk.
-
Phimosis: Phimosis is a condition in which the foreskin cannot be pulled back to expose the glans (head) of the penis. This can lead to inflammation, irritation, and difficulty in cleaning the area, potentially increasing the risk of penile cancer.
-
Poor Hygiene: Inadequate penile hygiene, which can lead to the accumulation of smegma (a mixture of dead skin cells and body oils) under the foreskin, may contribute to the risk of penile cancer.
-
Age: Penile cancer is more common in older men, with the highest incidence in those over 60 years old.
-
Personal and Family History: A personal history of penile cancer or a family history of the disease may be associated with an increased risk.
It's essential to understand these risk factors and take preventive measures where possible. For example, practicing safe sex to reduce the risk of HPV infection and quitting smoking can help lower the risk of penile cancer. Maintaining proper penile hygiene and considering circumcision (although this is a personal choice) can also contribute to reducing the risk. Regular medical check-ups and early detection are important to facilitate prompt diagnosis and treatment if penile cancer does develop, potentially improving the chances of a favorable outcome.

Symptoms
Symptoms of penile cancer may include:
-
Changes in the Skin: Penile cancer often begins with changes in the skin of the penis. These changes can manifest as thickening, reddening, or a velvety texture on the skin.
-
Lumps or Growths: Unusual lumps, warts, or growths on the penis may be a symptom of penile cancer. These may appear as raised, irregular, or ulcerated areas on the skin.
-
Pain or Discomfort: Some individuals with penile cancer experience pain, tenderness, or discomfort in the genital area. This discomfort may be persistent or intermittent.
-
Bleeding: Bleeding from the penis, especially unrelated to injury or trauma, is a concerning symptom. It may manifest as bleeding from the skin, under the foreskin, or during urination.
-
Swelling: Swelling of the penis or nearby lymph nodes may occur as the cancer progresses.
-
Foul Odor: In advanced cases, penile cancer may produce a foul-smelling discharge or odor.
-
Difficulty Urinating: Changes in urination patterns, including pain, difficulty in starting or stopping urination, or changes in the urinary stream, can be indicative of penile cancer.
It is important to emphasize that these symptoms can also be related to non-cancerous conditions. Nevertheless, if you notice any of these symptoms, particularly if they are persistent or worsen, it is essential to seek prompt medical evaluation by a healthcare professional. Early detection and diagnosis of penile cancer can lead to more effective treatment and better outcomes. If you are at higher risk due to factors like smoking, a history of HPV, or a family history of penile cancer, it is advisable to maintain regular check-ups and be vigilant about any unusual symptoms.
Diagnosis
The diagnosis of penile cancer involves a series of medical evaluations, tests, and procedures to confirm the presence of cancer, determine its stage, and guide treatment decisions. Here is an overview of the diagnostic process for penile cancer:
-
Medical History and Physical Examination:
-
The initial step is often a comprehensive medical history, where the patient discusses any symptoms, risk factors, and relevant health information.
-
A thorough physical examination is conducted to assess the genital area, including the penis and nearby lymph nodes. Any changes in the skin, presence of lumps or growths, and any discomfort or pain are carefully evaluated.
-
-
Imaging Studies:
-
Imaging tests may be performed to visualize the penis and the extent of the disease. These tests can include:
-
Ultrasound: This imaging technique can provide detailed images of the penis and surrounding structures.
-
Computed Tomography (CT) Scan: A CT scan may be used to assess the spread of cancer to nearby lymph nodes and organs.
-
-
-
Biopsy:
-
A definitive diagnosis of penile cancer often involves a biopsy. During this procedure, a small sample of the affected tissue is removed for examination. Several types of biopsies can be performed, such as incisional biopsy or punch biopsy.
-
The biopsy sample is sent to a pathologist who examines it under a microscope to determine if cancer cells are present and, if so, to identify the type of cancer and its characteristics.
-
-
Staging:
-
If penile cancer is confirmed, it is staged to determine the extent of the disease. Staging helps assess whether the cancer is localized to the penis or has spread to nearby lymph nodes or distant organs. Staging information is crucial for treatment planning.
-
-
Blood Tests:
-
Blood tests, such as a complete blood count (CBC) and basic metabolic panel (BMP), may be conducted to assess the patient's overall health and kidney function.
-
Once the diagnosis and staging are complete, a healthcare team can work with the patient to develop a personalized treatment plan tailored to the specific characteristics of the cancer and the patient's overall health. Treatment options for penile cancer may include surgery, radiation therapy, chemotherapy, or immunotherapy, depending on the stage and extent of the cancer.
Early detection and prompt diagnosis are crucial for improving outcomes in individuals with penile cancer. If you have any concerning symptoms or risk factors associated with penile cancer, it is important to consult with a healthcare provider for a proper evaluation and diagnosis.
Treatment
The treatment of penile cancer depends on several factors, including the stage and extent of the cancer, the location of the tumor, the patient's overall health, and individual preferences. Treatment options for penile cancer may include:
-
Surgery:
-
Surgical removal of the cancerous tissue is the primary treatment for penile cancer. The extent of surgery depends on the stage and location of the tumor:
-
Local Excision: In cases of early-stage penile cancer, a surgeon may remove the tumor and a margin of healthy tissue.
-
Partial Penectomy: This procedure involves the removal of part of the penis while preserving as much function as possible.
-
Total Penectomy: In cases where the cancer has advanced significantly, the entire penis may need to be removed. This is a life-altering procedure, and reconstructive surgery (penile prosthesis or phalloplasty) may be considered to improve quality of life.
-
-
-
Lymph Node Surgery:
-
If the cancer has spread to nearby lymph nodes, a surgeon may perform a lymph node dissection (inguinal lymph node dissection) to remove affected lymph nodes.
-
-
Radiation Therapy:
-
Radiation therapy uses high-energy X-rays to target and destroy cancer cells. It may be used in specific cases to treat penile cancer, especially when surgery is not a suitable option.
-
-
Chemotherapy:
-
Chemotherapy, which uses drugs to kill or slow the growth of cancer cells, is typically less commonly used for penile cancer. It may be considered in cases of advanced or metastatic disease.
-
-
Biological Therapy (Immunotherapy):
-
Immunotherapy drugs, such as pembrolizumab and nivolumab, can stimulate the immune system to recognize and attack cancer cells. They are used in some advanced penile cancer cases, particularly those with limited treatment options.
-
-
Clinical Trials:
-
Clinical trials may offer access to novel treatments and therapies for penile cancer. These trials investigate new approaches and medications that may provide additional options for individuals with the disease.
-
The choice of treatment depends on the specific characteristics of the cancer, such as its stage and grade, as well as the patient's age, overall health, and personal preferences. Treatment plans are typically discussed with a healthcare team, which may include urologists, medical oncologists, radiation oncologists, and other specialists.
Penile cancer and its treatment can have a profound impact on a person's physical and emotional well-being. Open and honest communication with the healthcare team is crucial to make informed decisions about the most appropriate treatment plan and address any concerns or questions. In some cases, psychotherapy and support from counselors or support groups can be valuable resources for coping with the emotional aspects of the disease and its treatment.
