Penile Discomfort: Is It a Tumor or Normal Variation? - Urology

More Info

When it comes to penile discomfort, particularly when you notice a small, elongated structure on the left side of the shaft during an erection, it is understandable to feel concerned about the possibility of a tumor or some abnormality. Based on your description, it seems that you have already consulted a urologist, which is a positive step toward addressing your concerns.

The structure you are feeling, measuring about 2 to 3 mm in length and 0.5 mm in width, could potentially be a normal anatomical variation, such as a blood vessel or a small fibrous band. The fact that it is only palpable during an erection and not at rest suggests that it may be related to the vascular structures of the penis, such as veins or arteries, which can become more prominent when engorged with blood.

Your urologist mentioned the possibility of a "venous or arterial anomaly," which could refer to a condition known as a varicocele or a venous plexus. A varicocele is an enlargement of the veins within the scrotum, but it can also cause discomfort in the surrounding areas, including the penis. This condition is generally benign and does not indicate the presence of cancer.

The discomfort you occasionally feel, described as a "weird feeling" or mild pain, could be attributed to several factors, including:
1. Nerve Sensitivity: The penis is highly sensitive, and variations in sensation can occur due to nerve irritation or sensitivity, especially if you are wearing tighter clothing.

2. Muscle Tension: Sometimes, tension in the pelvic floor muscles can lead to discomfort in the genital area.

3. Psychological Factors: Anxiety about potential health issues, particularly cancer, can heighten awareness of bodily sensations, leading to a perception of discomfort that may not be present otherwise.

4. Inguinal or Scrotal Issues: Since you mentioned occasional pain in the area connecting the thigh to the testicles, this could indicate a related issue, such as referred pain from the groin or scrotum.

5. Normal Variations: The penis has various structures, including veins, arteries, and connective tissue, which can sometimes be felt more prominently under certain conditions.

Regarding your concern about tumors or cancer, it is essential to note that penile cancer is relatively rare, and the symptoms typically include visible changes such as lumps, sores, or changes in skin texture. Since your urologist did not find any abnormalities during the examination, it is likely that what you are experiencing is not indicative of cancer.

If your discomfort persists or worsens, or if you notice any new symptoms such as changes in skin color, lumps, or persistent pain, it would be prudent to follow up with your urologist. They may recommend further evaluation, such as an ultrasound or other imaging studies, to rule out any underlying conditions.

In summary, while it is natural to worry about potential health issues, the symptoms you describe are more likely related to normal anatomical variations or benign conditions rather than a serious problem. Maintaining open communication with your healthcare provider and addressing any ongoing concerns will help ensure your peace of mind and overall health.
