Testicular Lumps: Concerns About Cancer and Health

Testicular issues

Hello doctor, yesterday I felt a hard lump about 0.3-0.4 cm in size next to my left testicle, near the epididymis.
It doesn't hurt when I touch it, and I would like to ask if this lump could be testicular cancer or if it might be something else.
Today, I can't feel it anymore, and I'm quite worried.
Additionally, I understand that testicular cancer typically causes one testicle to become hard, but I notice that during the day, my testicles feel firm and slightly larger (due to prolonged sitting, my testicles are elevated).
However, when I lie down at night and use my phone, my scrotum relaxes, and my testicles feel smaller and softer (though still firmer than before).
Could this be caused by testicular cancer, or is it possibly due to not having masturbated for a while? Lastly, I want to ask about the position of my testicles; my left testicle usually points towards 11 o'clock and the right towards 1 o'clock.
At night, when I sleep on my side, they tend to shift around due to relaxation.
Is this position likely to cause torsion? Thank you, doctor.

Based on your description, it doesn't seem like a testicular cancer issue.
Additionally, the likelihood of testicular torsion is quite low; it typically occurs more frequently in teenagers.
Since you are in your 20s, you should be more stable.
If you are still concerned, it is important to visit a urologist for a thorough examination and discuss it with the physician.

When it comes to concerns about testicular lumps, it's essential to approach the situation with a clear understanding of the potential causes and the necessary steps for evaluation. Based on your description of a hard lump near your left testicle, measuring approximately 0.3-0.4 cm, there are several possibilities to consider.

Firstly, it's important to note that not all lumps in the testicular area are indicative of cancer. Testicular cancer typically presents as a firm, painless mass within the testicle itself. However, lumps can also arise from other conditions, such as epididymal cysts, varicoceles, or even infections like epididymitis. The fact that you mentioned the lump was not painful and that you could not feel it the following day may suggest that it could be a transient issue, such as a cyst or a temporary swelling.

Testicular cancer is more common in younger men, particularly those between the ages of 15 and 35, but it is still relatively rare. The characteristics of testicular cancer often include a hardening of the testicle itself rather than just a lump on the surface. If the lump is not consistently palpable or if it changes in size or disappears, it may not be a cause for immediate concern. However, any persistent changes in the testicles should be evaluated by a healthcare professional.

Regarding your observation that your testicles feel firmer and larger during the day and softer at night, this is not uncommon. Factors such as temperature, position, and even arousal can affect the size and firmness of the testicles. The scrotum is designed to regulate temperature for optimal sperm production, which is why the testicles may retract closer to the body in cooler conditions or when sitting for long periods.

As for your concern about testicular torsion, this condition occurs when the spermatic cord becomes twisted, cutting off blood supply to the testicle. While the position of your testicles can vary, the risk of torsion is not significantly influenced by their orientation. However, if you experience sudden severe pain, swelling, or changes in color of the scrotum, you should seek immediate medical attention, as torsion is a surgical emergency.

In conclusion, while your concerns about testicular cancer are valid, it's crucial to remember that not all lumps are cancerous. The best course of action is to schedule an appointment with a urologist for a thorough examination. They may perform an ultrasound to assess the lump and rule out any serious conditions. Regular self-examinations are also encouraged, as they can help you become familiar with the normal size and shape of your testicles, making it easier to identify any changes. If you notice any persistent lumps, changes in size, or other symptoms such as pain or discomfort, do not hesitate to seek medical advice. Early detection and intervention are key to managing any potential health issues effectively.
