what are the causes of respiratory disorders such as Bronchitis pneumonia and lung cancer​

here's ur answer dude

Evidence suggests that there is a relationship between previous respiratory disease (PRD), including chronic bronchitis, emphysema, tuberculosis, and pneumonia, and lung cancer diagnoses (2). Tobacco is a shared risk factor of PRD and lung cancer.

Bronchiectasis causes abnormal widening of the airways, making it difficult to rid the lower airways of mucus and phlegm, which raises the risk of infection.

Cystic fibrosis is a genetic condition that causes mucus in organs, including the lungs, to become thick and sticky. Respiratory complications include infections, inflammation and respiratory failure.

Lung cancer affects the lungs in multiple ways. Tumors may block airways, or fluid can collect around either lung, making expansion difficult. Lung cancer can also cause inflammation in the respiratory system.

Pneumonia is a lung infection most commonly caused by bacteria or viruses. People with chronic respiratory conditions like COPD are more vulnerable to developing pneumonia.

Tuberculosis is a bacterial infection that affects the lungs and other parts of the body. TB can be inactive, or latent, for many years.


Certain factors are known to contribute to respiratory disease. For others, the cause is unclear. these are some causes or risk factors:

Smoking ,Environmental,Autoimmune conditions,Genetic.


Symptoms can vary by the type of respiratory condition, although some symptoms are common to several disorders.

Shortness of breath with activity.

Persistent cough.

Wet cough with mucus (COPD, cystic fibrosis, asthma).

Dry, "nonproductive" cough (pulmonary fibrosis).

Chest tightness.


Rapid, shallow breathing.


Recurring respiratory infections.Fatigue.
