Your health is written in your hands

Signs to show your GP

Club fingers - fingertips that are dome-shaped, or look like small clubs, are a warning sign of lung cancer, as this anomaly is caused by build-up of a substance called PGE2 that dampens inflammation of the lungs and goes into overdrive if there is a lung tumour.

Oversized hands - hands that become swollen and enlarged may be a sign of acromegaly, caused by a tumour on the pituitary gland that controls production of the growth hormone. Feet, lips, nose and ears can also grow larger.
Two-tone nails - if your nails are pale at the top but brownish towards the tip (known as half-and-half nails), you could have kidney disease. Nail discoloration is thought to be caused by a build-up of urea crystallising under the skin and nails.
