Answer:
a. Stroke: Stop smoking
b. Obesity: Exercise regularly
c. Skin cancer: Avoid UV exposure
Explanation:
Tobacco contains at least 7000 chemicals including some toxic and carcinogenic chemicals like carbon monoxide, cyanide, arsenic, etc. During smoking, we inhale these chemical and through lungs these chemicals get into our blood. It can cause clotting in the blood, thickening of arteries and other problems which can result in stroke.
The main cause of obesity is the sedentary lifestyle and unhealthy eating. We gain weight when we intake more calories than burning. Therefore regular exercise is important, especially for obese people to burn extra calories they consume.
UV radiation has the ability to cause mutation when skin is exposed to UV radiation. If the damage is more than the mutation can cause uncontrolled growth of cell which can result in skin cancer. So UV exposure should be avoided to prevent skin cancer.
