Penile cancer is a rare type of cancer that develops in the tissues of the penis. Although it is uncommon, knowing its warning signs can be important because early diagnosis may make treatment easier.

Penile cancer can develop in different parts of the penis, including the skin, foreskin, or head of the penis. It is more common in older adults, but it can occur at other ages as well.

Understanding the possible risk factors, symptoms, and diagnostic process can help people recognize changes that should be checked by a healthcare professional.

What Is Penile Cancer?

Penile cancer occurs when abnormal cells in the tissues of the penis begin to grow uncontrollably.

Most penile cancers are squamous cell carcinomas, which develop from cells on the surface of the penis. Other, much less common types can also occur.

Like other cancers, penile cancer can sometimes spread to nearby lymph nodes or other parts of the body if it is not detected and treated.

What Are the Symptoms of Penile Cancer?

Penile cancer may cause changes in the skin or tissues of the penis.

Possible symptoms include:

• A growth, lump, or sore on the penis

• A change in the color or thickness of the skin

• A sore that does not heal

• Bleeding from the penis

• Unusual discharge

• Persistent irritation or pain

• Swelling of the penis

• A lump in the groin

• Difficulty pulling back the foreskin in uncircumcised men

Some of these symptoms can also be caused by infections, inflammation, or other non-cancerous conditions.

However, a persistent change should be examined rather than ignored.

What Are the Risk Factors for Penile Cancer?

Several factors may increase the risk of developing penile cancer.

HPV Infection

Certain types of human papillomavirus, or HPV, are linked to an increased risk of penile cancer. HPV is a common infection and many infections clear naturally, but some persistent high-risk infections can cause cellular changes.

Tobacco Use

Smoking and other forms of tobacco use can increase the risk of several cancers, including penile cancer.

Poor Hygiene

Difficulty keeping the penis clean, particularly under the foreskin, may contribute to chronic irritation and inflammation.

Phimosis

Phimosis is a condition in which the foreskin is difficult or impossible to pull back. Persistent phimosis may be associated with a higher risk of penile cancer.

Age

The risk of penile cancer generally increases with age. It is more frequently diagnosed in older men.

Weakened Immune System

People with weakened immune systems may have a higher risk of developing certain cancers and infections, including conditions associated with penile cancer.

Having one or more risk factors does not mean a person will definitely develop penile cancer.

How Is Penile Cancer Diagnosed?

A doctor will usually begin with a physical examination. The penis and nearby areas may be carefully examined for unusual growths, sores, discoloration, or swelling.

If an abnormal area is found, a biopsy may be recommended. During a biopsy, a small tissue sample is removed and examined in a laboratory to determine whether cancer cells are present.

Additional tests may be needed if cancer is confirmed. Imaging tests or examinations of nearby lymph nodes can help doctors understand whether the cancer has spread.

Why Is Early Diagnosis Important?

Early diagnosis can make a significant difference in how penile cancer is managed.

When the disease is found while it is still limited to the penis, treatment may be less extensive. If the cancer has spread to nearby lymph nodes or other parts of the body, treatment can become more complex.

This is why persistent changes should be evaluated instead of waiting for them to disappear on their own.

Can Penile Cancer Be Prevented?

There is no guaranteed way to prevent every case of penile cancer, but certain measures may help reduce risk.

Avoiding tobacco, practicing good genital hygiene, and discussing HPV vaccination with a healthcare professional may help reduce the risk of conditions associated with penile cancer.

People with persistent foreskin problems or unusual changes should seek medical advice.

When Should You See a Doctor?

A sore, lump, skin change, bleeding, discharge, or swelling that does not go away should be checked by a healthcare professional.

It is understandable that people may feel uncomfortable discussing changes involving the penis. However, delaying medical care can make diagnosis more difficult.

A doctor can determine whether the change is caused by cancer, an infection, inflammation, or another condition.

FAQs

Is penile cancer common?

No. Penile cancer is relatively rare compared with many other types of cancer.

Can HPV increase the risk of penile cancer?

Yes. Certain high-risk HPV types are associated with an increased risk of penile cancer.

Is every lump or sore on the penis cancer?

No. Many penile lumps, sores, and skin changes are caused by infections, irritation, inflammation, or other conditions. Persistent changes should still be evaluated.

Can penile cancer be treated?

Yes. Treatment depends on the type, size, location, and stage of the cancer. Early-stage disease may have more treatment options.

Can penile cancer spread?

Yes. Penile cancer can spread to nearby lymph nodes and, in more advanced cases, to distant parts of the body.

Conclusion

Penile cancer is rare, but recognizing unusual changes can help with early diagnosis. A persistent sore, lump, skin change, bleeding, discharge, or swelling should not be ignored.

Several factors, including HPV infection, tobacco use, chronic inflammation, phimosis, and age, can increase risk. If you notice a change that does not improve, speaking with a healthcare professional is the safest way to find out what is causing it.
