Which condition is suspected for a 20-year-old male with a bump on his testicle and history of unprotected intercourse?

The suspicion of testicular cancer in a 20-year-old male with a testicular bump and a history of unprotected intercourse is supported by several important clinical considerations. Testicular cancer is relatively common in young men and can present as a painless lump or swelling in the testicle. This demographic is particularly at risk, and the presence of a discrete mass warrants further investigation to rule out malignancy.

In addition to the age and presentation, risk factors such as a history of cryptorchidism or family history of testicular cancer may also play a role in the assessment. Given the patient's age and the commonality of testicular cancer in this group, along with the new onset of a lump, the likelihood of malignancy must be considered seriously.

Other conditions, while possible, are less aligned with the specific symptomatology or demographic; for instance:

• Testicular torsion typically presents with acute severe pain and is often accompanied by nausea. The lack of pain suggests it is less likely in this scenario.

• Hydrocele usually presents as a fluid-filled sac that can cause swelling but doesn’t normally manifest as a discrete hard bump, making it less likely the cause in this case.

• Epididymitis is often related to infection and usually presents with
