Penile cancer is a rare but serious condition that affects men’s health. This type of cancer develops in the tissues of the penis and can have significant physical and emotional impacts on those diagnosed. While it accounts for less than 1% of all male cancers in the United States, understanding penile cancer is crucial for early detection and effective treatment.
This article aims to shed light on penile cancer, covering its symptoms, treatment options, and prevention methods. We’ll explore the risk factors that contribute to its development and discuss the importance of early detection. Additionally, we’ll delve into the various treatment approaches available and provide insights on how to reduce the risk of developing this condition. By raising awareness about penile cancer, we hope to encourage men to be proactive about their health and seek medical attention when needed.
Understanding Penile Cancer
Anatomy of the Penis
The penis consists of several distinct anatomical structures. The shaft, or body of the penis, contains three cylindrical spaces of erectile tissue: the paired corpora cavernosa on the dorsal side and the corpus spongiosum, which surrounds the urethra, on the ventral side. The glans penis, an expansion of the corpus spongiosum, forms the head of the penis. In uncircumcised men, the glans is covered by the foreskin, or prepuce. Penile cancer most frequently develops on the glans or foreskin but can occur anywhere on the penis.
How Cancer Develops
Penile cancer typically begins when healthy cells in or on the penis develop changes (mutations) in their DNA. A cell’s DNA contains the instructions that tell the cell what to do. The changes tell the cells to grow out of control and to continue living after healthy cells would normally die. The accumulating abnormal cells form a tumor that can grow to invade nearby tissue. In some cases, abnormal cells can break off and spread (metastasize) to other parts of the body. The type of cell that becomes cancerous determines the type of penile cancer.

Prevalence and Statistics
Penile cancer is a rare malignancy, accounting for less than 1% of cancers among men in the United States and other developed countries. However, in some developing nations, penile cancer can account for up to 10-20% of cancers in men. The incidence of penile cancer increases with age, with the disease being most frequently diagnosed between the ages of 50 and 70 years. Certain populations, such as individuals with HIV infection, uncircumcised men, and those with a history of HPV infection, carry a higher risk of developing penile cancer.
Risk Factors and Prevention
Modifiable Risk Factors
Several modifiable risk factors have been identified that can increase the likelihood of developing penile cancer. Smoking is a significant risk factor, as tobacco use can damage cells and lead to the development of cancer-causing chemicals throughout the body, including the penis. Poor genital hygiene, particularly in uncircumcised men, can result in the buildup of smegma, a thick, foul-smelling substance that can cause chronic inflammation and irritation, potentially increasing the risk of penile cancer. Additionally, individuals who have received PUVA treatment, a type of phototherapy used to treat psoriasis, may be at a higher risk due to the radiation exposure involved in the treatment.
Non-Modifiable Risk Factors
In addition to modifiable risk factors, there are also non-modifiable factors that can contribute to the development of penile cancer. Age is a significant non-modifiable risk factor, with the majority of penile cancer cases occurring in men over the age of 50. Having a condition called phimosis, where the foreskin is too tight to be pulled back from the head of the penis, can also increase the risk of penile cancer. This condition can lead to inflammation and irritation, which may promote the growth of cancerous cells. Individuals with a weakened immune system, such as those living with HIV/AIDS, are also at a higher risk of developing penile cancer, as their bodies are less capable of fighting off infections and abnormal cell growth.
Preventive Measures
Fortunately, there are several preventive measures that can be taken to reduce the risk of developing penile cancer. Practicing good genital hygiene, especially for uncircumcised men, is crucial in preventing the buildup of smegma and reducing inflammation. This involves regularly cleaning the penis, including the area under the foreskin, with warm water and mild soap. Quitting smoking is another important step in reducing the risk of penile cancer, as well as many other types of cancer. Getting vaccinated against HPV can also help prevent infection with the virus, which is a significant risk factor for penile cancer. Practicing safe sex by using condoms and limiting the number of sexual partners can also reduce the risk of contracting HPV and other sexually transmitted infections that may increase the likelihood of developing penile cancer. Regular self-examination of the penis and prompt medical attention for any unusual changes, such as lumps, sores, or discoloration, can aid in the early detection and treatment of penile cancer.
Symptoms and Early Detection
Common Symptoms
Penile cancer often presents with visible changes to the skin of the penis. The most common symptoms include the appearance of a painless lump or sore on the penis, which may bleed. Swelling and irritation, particularly around the head of the penis (balanitis), can also be indicative of penile cancer. Other signs to watch out for include skin thickening or discoloration, flat growths with a blueish-brown hue, foul-smelling discharge under the foreskin, small crusty bumps, and a persistent rash. It is crucial to note that while these symptoms can be caused by penile cancer, they may also be the result of less serious conditions such as infections or allergic reactions. However, it is always best to have any unusual changes examined by a healthcare provider to rule out the possibility of cancer and ensure early detection and treatment if necessary.

Importance of Self-Examination
Regular self-examination of the penis is a key factor in the early detection of penile cancer. By familiarizing oneself with the normal appearance and feel of one’s penis, any changes or abnormalities can be quickly identified and brought to the attention of a healthcare provider. It is recommended that men perform a thorough self-examination at least once a month, carefully inspecting the skin of the penis, including the shaft, glans, and foreskin (if present), for any lumps, sores, discoloration, or other unusual changes. If any concerning signs are noticed, it is essential to seek medical advice promptly, as early diagnosis and treatment of penile cancer significantly improve the chances of successful outcomes. Incorporating self-examination into a regular hygiene routine can help make it a habit and increase the likelihood of detecting penile cancer in its early stages.
Treatment Approaches
Factors Affecting Treatment Choice
The choice of treatment for penile cancer depends on several factors, including the stage and grade of the tumor, the location and size of the lesion, and the patient’s overall health and preferences. Organ-sparing techniques are preferred whenever possible to preserve function and appearance. However, more extensive surgery may be necessary for larger or more invasive tumors. The presence of lymph node involvement also influences treatment decisions, as it may require additional interventions such as lymph node dissection or chemotherapy.
Treatment by Stage
Early-stage penile cancers (Tis, Ta, T1) can often be managed with penile-sparing techniques such as laser therapy, Mohs surgery, or topical treatments. Partial or total penectomy may be necessary for more advanced tumors (T2 or higher) or those invading the corpora cavernosa. Lymph node dissection is typically performed for patients with palpable inguinal lymphadenopathy or those at high risk for nodal metastases based on tumor characteristics. Chemotherapy and radiation therapy may be used in combination with surgery for locally advanced or metastatic disease.

Managing Side Effects
Treatment for penile cancer can have significant physical and psychological side effects. Patients may experience pain, swelling, and changes in urinary and sexual function following surgery. Lymphedema can occur after lymph node dissection. Radiation therapy may cause skin irritation, fibrosis, and strictures. Chemotherapy can lead to fatigue, nausea, and immunosuppression. Psychosocial support and rehabilitation services are essential to help patients cope with the impact of treatment on their quality of life. Careful follow-up is necessary to monitor for complications and recurrence.
