A new testicle lump that does not hurt: should you get it checked?

The NHS says lumps and swellings in the testicles are usually caused by something less serious, yet every new lump should be checked by a clinician. The US National Cancer Institute lists a painless lump or swelling among possible signs of testicular cancer. That does not mean your lump is cancer; it means lack of pain cannot tell you what it is.

Book an examination if you notice a lump, new swelling, a testicle becoming bigger, a change in how it feels or an ache that does not go away. Do not wait for pain to appear or for the lump to grow before asking. If you are unsure whether the change is in the testicle or the skin around it, that is another reason to have someone examine it.

You can say, ‘I found a new lump and would like it checked.’ The clinician may ask when you first noticed it, whether it has changed and whether there is swelling or discomfort. The NHS describes an examination of the testicles and, when needed, an ultrasound referral. A scan makes a picture of tissue; the clinician decides what tests are appropriate after hearing and examining you.

It is reasonable to feel embarrassed. You can ask how the examination will be done and request privacy. A phone or video conversation may help arrange care, but it cannot feel a lump or replace an in-person examination. Our short private guide can help you put the change into words; it cannot tell you its cause, and you need not finish it before booking the visit.

If you have sudden, severe testicle pain, pain with nausea or vomiting, or pain that continues for more than an hour or at rest, seek emergency medical care now. The NHS treats these as urgent symptoms that may need hospital treatment. Do not spend time comparing articles or taking an online guide first.

For a new lump without these emergency signs, arrange an in-person check rather than trying to reassure yourself from the absence of pain. Most people will not receive a serious diagnosis, but only an examination can move you from guessing to an appropriate next step.
