They should both be smooth with no lumps or swellings. It is quite normal for one to be larger than the other and for one to be lying lower. If you find anything unusual, then ask your GP to check them.

Men at greatest risk are people working outdoors such as farmers, fishermen or builders, especially if they have done so for many years. Always use a high factor sun block in strong sunshine.
