Every disease can be recognised based on warning symptoms. These can be recognized if you pay close attention to all changes that occur to your body.
According to some British scientists, the first signs of possible cancer appear on the hands. Usually they appear in a form of swellings or cracks, thickening and the skin becomes harsh.
Most people often ignore these symptoms but that is the worst what they can do because these symptoms help in diagnosing cancer in the early stage which gives time to doctors and the patient to prepare well and to act with medicine and suitable diet.
So if you happen to have some of these symptoms, make sure you see a doctor immediately, just to make thing safe.
