Moles on the Foreskin: Concerns and Cancer Risks

There are four to five moles of varying sizes on the foreskin?

Hello Doctor: Over the past two to three years, I have developed about four to five moles on my foreskin, of which only two or three have become darker (approximately 0.2 to 0.3 mm in size).
However, none of the moles have any raised surfaces, and throughout these years, my penis (including the foreskin) has not experienced any swelling, hardness, purulent discharge, foul-smelling secretions, bleeding, or itching.
Although my foreskin is slightly elongated, I have been able to retract it for cleaning, and I can also keep it retracted during erections; everything seems normal.
My sexual activity is limited to my girlfriend, and I have not engaged in promiscuous behavior or contracted any sexually transmitted diseases.
Now, I am very concerned about the sudden appearance of these flat moles on my foreskin over the past two to three years.
I would like to ask: 1.
Is this related to the occurrence of penile cancer? 2.
Why have these moles suddenly appeared? 3.
Is there a possibility that they could turn into malignant moles? 4.
If I choose not to undergo circumcision, are there other methods to determine the possibility of penile cancer? 5.
How are the stages of penile cancer (early, middle, late) differentiated, and what symptoms are associated with each stage? Thank you for your guidance—someone who is worried and fearful all day (27 years old).

Dear Concerned Individual,
Thank you for reaching out with your questions regarding the moles on your foreskin and your concerns about penile cancer. It’s understandable to feel anxious about changes in your body, especially when it comes to something as sensitive as the genital area. Let’s address your questions one by one, and I’ll provide some additional context to help you better understand the situation.

1. Are the moles related to penile cancer?
The presence of moles (nevi) on the foreskin does not automatically indicate a risk for penile cancer. However, any changes in the appearance of moles, such as darkening or changes in size, should be monitored closely. Penile cancer is relatively rare, and it typically presents with symptoms such as a growth or sore on the penis that does not heal, changes in skin color, or unusual discharge. Since you mentioned that the moles are not raised and there are no other concerning symptoms (like discharge or bleeding), it is less likely that they are indicative of cancer. Nevertheless, it is crucial to have any new or changing moles evaluated by a healthcare professional.

2. Why have the moles suddenly appeared?
The development of new moles can occur for various reasons, including genetic factors, sun exposure, or hormonal changes. It is not uncommon for individuals to develop new moles during their lifetime, especially in areas that are exposed to sunlight. However, if these moles are new and changing, it’s wise to consult a dermatologist for a thorough examination.

3. Will they turn into malignant moles?
While most moles are benign, some can develop into melanoma, a type of skin cancer. Factors that increase the risk of a mole becoming malignant include changes in color, size, shape, or texture. The ABCDE rule can help you remember what to look for: Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolving (changing) over time. If your moles exhibit any of these characteristics, it is essential to seek medical advice.

4. If I choose not to undergo circumcision, are there other ways to assess the risk of penile cancer?
If circumcision is not an option you wish to pursue, regular self-examinations of the genital area are important. Look for any changes in the skin, new growths, or unusual symptoms. Additionally, maintaining good hygiene and practicing safe sex can help reduce the risk of infections that may contribute to cancer risk. Regular check-ups with a healthcare provider can also help monitor any changes over time.

5. What are the stages of penile cancer and their symptoms?
Penile cancer is typically classified into several stages, which can be summarized as follows:
- Stage 0 (Carcinoma in situ): Abnormal cells are found in the inner lining of the penis but have not spread. Symptoms may include a flat lesion or a small growth.

- Stage I: The cancer has invaded deeper layers of the skin but has not spread to lymph nodes. Symptoms may include a growth or sore on the penis.

- Stage II: The cancer has spread to nearby tissues but not to lymph nodes. Symptoms may include a larger growth or sore.

- Stage III: The cancer has spread to nearby lymph nodes. Symptoms may include swollen lymph nodes in the groin or pelvis.

- Stage IV: The cancer has spread to distant parts of the body. Symptoms may include pain, weight loss, and other systemic symptoms.

In conclusion, while the presence of moles on your foreskin is not inherently alarming, it is essential to monitor them for any changes and consult a healthcare professional for a thorough evaluation. Regular check-ups and self-examinations are key to maintaining your health and addressing any concerns early on. If you have further questions or need clarification, don’t hesitate to reach out to a healthcare provider.

Take care, and I wish you all the best in your health journey.
