Which desies or disorders affects the lungs? how is it affected?

there are many diseases that affect the lungs like emphysema, cystic fibrosis, and lung cancer.
Emphysema is a type of chronic obstructive lung disease. It is often caused by exposure to toxic chemicals or long-term exposure to tobacco smoke. Emphysema is caused by loss of elasticity (increased compliance) of the lung tissue, destruction of structures supporting the alveoli, and destruction of capillaries feeding the alveoli. The result is that the small airways collapse during exhalation (although aveolar collapsability has increased), leading to an obstructive form of lung disease (airflow is impeded and air is generally "trapped" in the lungs in obstructive lung diseases). Symptoms include shortness of breath on exertion (typically when climbing stairs or inclines, and later at rest), hypoventilation, and an expanded chest.
Emphysema patients are sometimes referred to as "pink puffers". This is because emphysema sufferers may hyperventilate to maintain adequate blood oxygen levels. Hyperventilation explains why emphysema patients do not appear cyanotic as chronic bronchitis (another COPD disorder) sufferers often do; hence they are "pink puffers" (adequate oxygen levels in the blood) and not "blue bloaters" (cyanosis; inadequate oxygen in the blood).
Lung cancer is the malignant transformation and expansion of lung tissue, and is the most lethal of all cancers worldwide, responsible for 1.3 million deaths annually.[1] It is caused mainly by cigarette smoking, and mostly affects men, being the leading cause of death of men between the ages of 40 and 65. With increased smoking among women, lung cancer is now occurring in women, although it is far less common.[2] While some people who have never smoked do still get lung cancer, this appears to be due to a combination of genetic factors[3] and exposure to secondhand smoke.[4][5] Air pollution may also contribute to the development of lung cancer.[6][7][8]
Current research indicates that the factor with the greatest impact on risk of lung cancer is long-term exposure to inhaled carcinogens. The most common means of such exposure is tobacco smoke.
Treatment and prognosis depend upon the histological type of cancer, the stage (degree of spread), and the patient’s performance status. Treatments include surgery, chemotherapy, and radiotherapy.[9]
Cystic fibrosis (CF), also called mucoviscidosis, is a hereditary disease that affects the entire body, causing progressive disability and early death. Formerly known as cystic fibrosis of the pancreas, this entity has increasingly been labeled simply ‘cystic fibrosis.’[1]
Difficulty breathing and insufficient enzyme production in the pancreas are the most common symptoms. Thick mucous production as well as a low immune system results in frequent lung infections, which are treated, though not always cured, by oral and intravenous antibiotics and other medications. A multitude of other symptoms, including sinus infections, poor growth, diarrhea, and potential infertility (mostly in males, due to the condition Congenital bilateral absence of the vas Deferens) result from the effects of CF on other parts of the body. Often, symptoms of CF appear in infancy and childhood; these include meconium ileus, failure to thrive, and recurrent lung infections.
Cystic fibrosis is one of the most common life-shortening, childhood-onset inherited diseases. In the United States, 1 in 3900 children are born with CF.[2]. It is most common among Europeans and Ashkenazi Jews; one in twenty-two people of European descent carry one gene for CF, making it the most common genetic disease among them.
