You just need three minutes once a month to check your body.
You can perform the check up while in the bath or shower, when the skin of the scrotum is relaxed. Get to know your testicles and be aware of any unusual changes that may occur.
The testicles should be checked one at a time. Place the index and the middle finger under the testicle, while placing the thumbs on the top. Use both hands to roll it gently between your fingers.
Feel it for any hard lumps or size, shape changes. It is normal one testicle to be slightly larger than the other and to hang lower from the other.
If you have any doubts, see you general practitioner (GP), who will examine your testicles and scrotum for lumps or swelling. You may find the consultation embarrassing, particularly if you have never had a doctor perform this type of examination before, but doctors are used to it and it only takes a few minutes.
If the GP feels a lump, you will probably be referred to a urologist, who specialises in the urinary and male reproductive systems. In most cases, the urologist will arrange some tests, such as an ultrasound and blood test. If the tests show there is a tumour, you may need to have your testicle removed.
