Smoking and the relationship of certain diseases:
Smoking is a major risk factor for a wide range of diseases, including some of the leading causes of death and disability in the world. Here's a look at the relationship between smoking and some of the most common diseases:
Cancer:
Smoking is the leading cause of preventable cancer death, responsible for nearly one-third of all cancer deaths in the United States. It is particularly linked to lung cancer, but also increases the risk of cancers of the mouth, throat, larynx, esophagus, bladder, kidney, pancreas, cervix, and stomach.
Heart disease:
Smoking is a major risk factor for heart disease, the leading cause of death in the United States. It damages the blood vessels and heart, increasing the risk of heart attack, stroke, and other cardiovascular problems.
Stroke:
Smoking is a leading cause of stroke, the third leading cause of death in the United States. It damages the blood vessels and heart, increasing the risk of blood clots that can block blood flow to the brain.
Chronic obstructive pulmonary disease (COPD):
Smoking is the main cause of COPD, a progressive lung disease that makes it difficult to breathe. COPD includes emphysema and chronic bronchitis.
Diabetes:
Smoking can increase the risk of developing type 2 diabetes and make it more difficult to control blood sugar levels in people with diabetes.
Other diseases:
Smoking has also been linked to a number of other diseases, including tuberculosis, certain eye diseases, and problems of the immune system, such as rheumatoid arthritis.
The risk of developing these diseases is directly related to the amount and duration of smoking. Quitting smoking at any time can improve your health and reduce your risk of these diseases.
If you are concerned about the health risks of smoking, talk to your doctor. They can help you create a quit plan and provide support to help you quit smoking for good.
