While there is no proven method to prevent testicular cancer, early detection is crucial for successful treatment. Regular self-examination is a vital tool for this. Men should perform a testicular self-examination (TSE) once a month.

When to Perform a TSE:
The ideal time for a testicular self-examination is during or immediately after a warm bath or shower, as the scrotal skin will be relaxed, making examination easier.

How to Perform a TSE:
1. Examine Each Testicle Separately: Use both hands to examine each testicle. Place your index and middle fingers underneath the testicle and your thumbs on top.
2. Gently Roll the Testicle: Gently roll the testicle between your thumbs and fingers. It is normal for testicles to be slightly different in size.
3. Identify Normal Structures: You may feel a soft, cord-like structure at the back and top of the testicle; this is the epididymis, which stores and transports sperm. Do not confuse it with an abnormal lump.
4. Check for Abnormalities: Feel for any lumps, hardening, swelling, or changes in size or shape within the testicle itself. Lumps can range from pea-sized or larger and are often painless.

When to Seek Medical Advice:
If you notice any changes, such as a lump or nodule, hardness, persistent pain, or a noticeable increase or decrease in testicular size, consult a doctor without delay. Early consultation is key.
