It’s no substitute for a visit to the doctor, but performing this 15-minute self-exam once a month could help you identify areas that need a professional opinion

Monitor your manhood

Roll your testes around in your hand. “They should feel like rugby-ball-shaped structures in the scrotal sack,” says Dr Ged Foley. If you feel any hard nodules, or notice any changes in weight and density, see a doctor immediately.

Scan your skin

Examine your entire body for changes in the size, shape, colour and outline of any moles or lesions. Also check for itchiness and bleeding, and have your partner or a friend check your back. “It’s the most common location for lesions,” says Foley.

Go over your glands

Check the glands in your neck, armpits and groin for unusual swellings and hard lumps. “Lumps could be a sign of lymphoma or a secondary spread from a cancer,” warns Foley.

Watch your weight

Jump on the scales and measure your height. Divide your weight by your height to calculate your BMI, which is the most widely accepted guide to healthy weight. A BMI of 20-25 is considered healthy for young to middle-aged men. Twenty-six to 30 is overweight and over 30 is obese.

Ask yourself some 
questions

To get a gauge of your psychological wellbeing look at how you’re sleeping. Is your concentration faltering? Have you lost the ability to enjoy life? Trouble with any of these could be a sign of depression.
