Penile Cancer
The external male genital organ called the penis comprises three tubes, namely, the corpus spongiosum & 2 corpora cavernosa, wherein the corpora cavernosa consists of spongy erectile tissues along with blood vessels and nerves. The corpora spongiosum serves as a protective sheath for the urethra and terminates into the glans penis.
The formation of tumours on the penis tissues called penile cancer initially emerges as blisters on the foreskin, head or shaft of the penis and transforms into a wart-like growth discharging blood or foul-smelling liquid. Infection of Human papillomavirus (HPV)increases the risk of penile cancer and can be prevented with condom use and HPV vaccines.
Symptoms of Penile Cancer:
Types of Penile Cancer
- Squamous cell carcinoma: This is the most common type of cancer and is found in 95% of the cases.
- Basal Cell Carcinoma: These cancers grow slowly and rarely metastasize to other parts of the body.
- Melanoma: The deepest layer of the epidermis consists of melanocytes, the skin cells responsible for producing melanin – a pigment accountable for brown skin colour, which protects us from UV rays. The malignant transformation of melanocytes is called melanoma, which is an aggressive tumour with high chances of lymph nodal and distant metastasis.
- Sarcoma: These tumours are aggressive and develop from connective tissues of the penis.

Causes of Penile Cancer
- Phimosis and lack of personal hygiene: The inability to retract the preputial skin is called phimosis. The smegma, a by-product of bacterial action on desquamated cells in the preputial sac, causes discomfort and is responsible for malignant transformation.
- HPV infection: Human Papillomavirus (HPV), contracted through unprotected sexual activities with more sexual partners, increases the risk of infection. Some strains of this virus particularly HPV type 16 & 18 are accountable for most of the penile cancers in patients.
- HIV infection: HIV and AIDS compromise the immune system, making the body susceptible to multiple diseases, including the formation of cancer cells.
- Use of tobacco products: Smoking and use of smokeless tobacco (Hans, Gutkha, betel quid etc.) increase the risk of acquiring penile cancer.
- Chronic balanitis: Chronic infection and inflammation of the glans penis is common in immunosuppressed individuals having been diagnosed with diabetes, AIDS, and organ transplant patients, and is associated with an increased risk of penile cancer.
- Lichen sclerosis: Lichen sclerosis is an uncommon condition that leads to patchy-white skin that appears thinner than normal, affecting the genital and anal areas and is associated with an increased risk of acquiring penile cancer.
Prevention of Penile Cancer
Preventive measures to stay safe against penile cancer are:
Neonatal circumcision: Having a circumcision done in the neonatal age group is proven to be protective against penile cancer.
- Maintaining proper hygiene, especially in the genital areas
- Use of protective barriers during sexual intercourse
- Avoiding multiple sexual relations
- Quits smoking and other tobacco products

Treatment for Penile Cancer
The treatment regimen consists of:
- Moh’s micrographic surgery: In case of very small tumours, the tumour is removed layer by layer, preserving a sizeable portion of normal penile tissues as possible.
- Circumcision:In small tumours affecting the preputial skin (foreskin) only a circumcision is executed.
- Glansectomy: For small tumours affecting the glans penis, only the glans is removed and called glansectomy.
- Partial penectomy:For tumours involving the distal part of the penile shaft, a partial penectomy is executed, and the residual penile stump is adequate for passing urine in upright posture and for sexual intercourse with his partner.
- Total penectomy with perineal urethrostomy:For large tumours, wherein an adequate penile stump cannot be left behind, a total penectomy is executed with perineal urethrostomy (creating a new opening for urethra in the perineum for passing urine).
- Groin lymph node dissection: Unilateral or bilateral groin lymph node dissection may be performed for patients with proven or suspicious groin lymph nodal spread.
