The answer is :
Smoking can cause about 87% of all cases of lung cancer.
As many as 80-90 percent of lung cancer cases are caused by smoking, but that does not mean people who do not smoke will be far from the disease, instead, several other factors cause lung cancer.
The United States Prevention Unit issued a list of people at high risk of lung cancer that has a history of 30 years of smoking, aged 55 to 80 years, and smoked in the last 15 years. Nevertheless, lung cancer can affect anyone.
Cigarette smoke is responsible for approximately 7,300 lung cancer deaths each year in the United States. Tobacco products contain more than 7,000 chemicals, and at least 70 of them are known to contain cancer-causing substances.
The signs and symptoms that indicate lung cancer are:
- Symptoms of the airways: coughing, coughing up blood, wheezing or shortness of breath
- Systemic symptoms: weight loss, fever, clubbing on fingernails, or fatigue
- Symptoms due to pressure in the local area: chest pain, bone pain, superior vena cava obstruction, difficulty swallowing
The causes of lung cancer are:
- Smoking (increases risk by 20-30% of lung cancer)
- Radeon gas (increases risk by 8-16% lung cancer)
- Asbestos
- Air pollution (responsible for 1-2% of lung cancer)
- Genetics (estimated 8-14% due to heredity)
