There is a lump on the scrotum?


I have a small bump on my scrotum that is less than one centimeter in size and resembles a pimple.
It is not painful or itchy most of the time, but it does hurt a little if I squeeze it (similar to the time it takes for me to stop feeling pain after pinching myself).
This bump does not affect my daily life or masturbation; it has just been there for a while (at least a few months).
I would like to ask the doctor whether this condition should be treated or if it is benign like a sebaceous cyst and can be left alone as long as it does not cause any issues.

Hello: If time permits, it is advisable to consult a urologist at the hospital for peace of mind.
If there is an increase in size, change in color, or discharge, it is essential to seek medical attention, as it is likely a sebaceous cyst or glandular issue.
Wishing you good health.

When it comes to a small lump on the scrotum, such as the one you described, it is important to approach the situation with caution and awareness. While the lump may not be causing you pain or discomfort in your daily activities, there are several factors to consider when deciding whether to seek medical advice.

Firstly, the characteristics of the lump are crucial. You mentioned that it resembles a small pimple and is less than one centimeter in size. The fact that it does not itch or cause pain unless manipulated is a positive sign, but it does not rule out the need for a medical evaluation. Lumps in the scrotal area can be caused by various conditions, some benign and others requiring medical attention.

Common causes of scrotal lumps include:
1. Epididymal Cysts: These are fluid-filled sacs that can develop in the epididymis, the tube that carries sperm from the testicles. They are usually painless and benign.

2. Sebaceous Cysts: Similar to epidermoid cysts, these are small lumps that can form due to blocked sebaceous glands. They are typically harmless but can become inflamed or infected.

3. Varicocele: This is an enlargement of the veins within the scrotum, which can sometimes feel like a lump. It is more common on the left side and can affect fertility.

4. Hernias: An inguinal hernia can present as a lump in the scrotum, especially if there is a protrusion of abdominal contents.

5. Testicular Tumors: While less common, any persistent lump in the scrotum should be evaluated to rule out testicular cancer, especially if there are changes in size, shape, or associated symptoms.

Given that the lump has been present for several months without change, it may be less likely to be a serious condition, but it is still advisable to consult a healthcare professional. A doctor can perform a physical examination and may recommend an ultrasound to assess the lump further. This imaging can help determine the nature of the lump and whether any further action is necessary.

In terms of when to seek medical advice, consider the following guidelines:
- Duration: If the lump has been present for more than a few weeks without improvement or resolution, it is wise to seek medical evaluation.

- Changes: If you notice any changes in size, shape, or color of the lump, or if it becomes painful, it is important to consult a doctor.

- Associated Symptoms: If you experience any additional symptoms such as swelling, redness, fever, or changes in urination, these could indicate an infection or other complications that require prompt attention.

In conclusion, while the lump may appear benign, it is always better to err on the side of caution when it comes to any new or persistent growth in the scrotal area. A healthcare provider can provide reassurance, a proper diagnosis, and treatment options if necessary. Regular self-examinations and awareness of your body are key components of maintaining reproductive health. If you have any doubts or concerns, do not hesitate to reach out to a medical professional for guidance.
