About Penile Cancer
The causes of penile cancer are not fully understood. However, some possible risk factors have been identified.
Non-modifiable risk factors for penile cancer are factors that cannot be changed. These include:
- Human papillomavirus (HPV) infection: Evidence suggests that most penile cancers occur due to HPV infections.
- Being uncircumcised: Some evidence suggests that penile cancer is more common in people without a circumcision.
- Phimosis and smegma: Conditions like phimosis (tight foreskin) and smegma (thick substance under the foreskin) can increase the risk of penile cancer due to irritation and inflammation.
Modifiable risk factors for penile cancer are factors that can be influenced or changed. These include:
- Smoking: People who smoke are at a higher risk of several cancers, including those that affect the penis, due to the carcinogens present in tobacco products.
- UV light treatment for psoriasis: Over time, this treatment can result in premature aging of skin cells, increasing the risk of penile cancer.
It's important to note that these risk factors may increase the likelihood of developing penile cancer, but they do not guarantee its development. Regular screenings and practicing safe sex are also important preventive measures. Remember to consult with your healthcare professional for personalized advice.
The most common early symptoms of penile cancer are:
- A bump or lump on the penis that may bleed, be sore, or have an unusual color.
- Skin changes, such as thickening or discoloration on the head, foreskin, or shaft of the penis.
- A sore on the penis that may bleed.
- Itching or irritation of the skin.
- Swelling near the tip of the penis, especially noticeable in uncircumcised men.
As penile cancer progresses or becomes more severe, other common symptoms may include:
- Crusty bumps or growths on the penis.
- Foul-smelling discharge under the foreskin.
- Bleeding beneath the foreskin.
- Red rash under the foreskin.
- Formation of bluish-brown growths.
- Swollen lymph nodes in the groin.
It's important to note that these symptoms can also be caused by other conditions, so it's crucial to consult a doctor for a proper diagnosis. Early detection and treatment significantly improve the chances of successful outcomes.
To diagnose penile cancer, the following examinations, tests, and procedures are commonly performed:
- Physical examination: A doctor will visually inspect the penis for any lumps, masses, or sores that may indicate cancer.
- Biopsy: A small sample of skin or tissue from the penis is removed and analyzed under a microscope to check for the presence of cancer cells.
- Cystoscopy: A thin tube with a camera is inserted into the penis opening and through the bladder to examine the different areas of the penis and surrounding structures.
- Ultrasound: High-energy sound waves are used to create images of body tissues, providing additional information about the condition.
To determine the stage or severity of penile cancer, additional examinations, tests, and procedures may include:
- CT scan (CAT scan): Detailed images of the pelvis are taken from different angles to assess the location and size of the tumor.
- PET scan (positron emission tomography scan): A small amount of radioactive glucose is injected into a vein, and a scanner detects areas where cancer cells are more active.
These tests help doctors understand the extent of cancer spread and guide treatment decisions. It's important to consult with your doctor about which tests are appropriate for your individual situation.
The goals of treatment for penile cancer are to achieve complete tumor removal, preserve organ function and appearance, and improve the quality of life. The recommended treatments and their mechanisms are as follows:
- Surgery: Surgical removal of the tumor is the primary treatment for early-stage penile cancer. This may involve circumcision, partial or total removal of the penis (penectomy), and removal of nearby lymph nodes. Surgery aims to remove the cancerous tissue and prevent its spread.
- Radiation therapy: High-energy X-rays or other radiation sources are used to kill cancer cells and shrink tumors. This treatment can be used to target and destroy cancer cells that may remain after surgery or in cases where surgery is not possible.
- Chemotherapy: Anticancer drugs are used to kill cancer cells throughout the body. Chemotherapy may be used in advanced cases of penile cancer or if the cancer has spread to other parts of the body. It works by targeting rapidly dividing cells, including cancer cells, and inhibiting their growth.
- Targeted therapy: Targeted drugs are designed to specifically focus on certain atypical structures or mutations in cancer cells, blocking their growth or causing their death. Targeted therapy is a newer approach and may be used in specific cases of penile cancer.
- Health behavior changes such as quitting smoking, maintaining a healthy weight, and practicing safe sex can also help reduce the risk of penile cancer.
Remember, treatment options may vary depending on the stage and extent of the cancer. It is important to consult with your healthcare professional for personalized advice.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
