3. Types of cancer –

3.1. Lung cancer :

Lung cancer is the primary type of cancer that causes death. Lung cancer is typically classified into two types and they are –

small cell lung cancer and non-small cell lung cancer.

Tobacco smoke is the main reason which leads to lung cancer. Tobacco smoke elevates the risk of lung cancer for a wide range of reasons such as the type of tobacco product used, the amount and time of tobacco smoke used, and genetic factors.

Secondhand smoke can also raise the chance of developing lung cancer.

Carcinogens in tobacco smoke damage the DNA cells and cause abnormalities that lead to cancer when the tobacco smoke is inhaled. Smoking tobacco can also damage other organs, causing irritation or inflammation and an increase in cell growth, resulting in cancer risk.

Tobacco smokers should quit smoking as it is the best way to reduce cancer risk of lung cancer.

It might be difficult for the chain-smokers to quit suddenly, but there are many other resources available, like nicotine and medications which would be helpful to reduce the smoking of tobacco. Does marijuana cause cancer?

Smoking tobacco can cause lung infections like –

I.) Chronic bronchitis –

Chronic bronchitis is one of the lung infections diseases which causes inflammation or irritation in the bronchial tubes.

Symptoms of this lung infection disease are coughing, difficulty in breathing, and excess production of mucus in the respiratory system or respiratory tract.

II.) Tuberculosis –

It is caused by a bacterial infection and this lung disease mainly affects the lungs and spreads to the other parts of the body.

Symptoms of this lung disease include coughing up blood, fever or tiredness, and sudden decrease in weight or reduction in weight(weight loss).
