Asthma is a chronic respiratory disease caused by inflammation and narrowing of the airways. This condition is based on the hypersensitivity of the respiratory tract and its overreaction to various stimuli, especially allergens or irritants. Asthma attacks are characterized by symptoms such as difficulty breathing, cough, wheezing and chest tightness. Asthma, which usually begins in childhood, can continue throughout life, but its symptoms can be controlled with appropriate treatment and management. Management strategies such as medications, breathing exercises, and avoiding environmental factors can help asthma patients improve their quality of life and minimize attacks.

COPD (Chronic Obstructive Pulmonary Disease) is a lung disease that causes long-term and often irreversible damage to the airways. COPD, often associated with smoking, causes narrowing of the airways and damage to lung tissue, making breathing difficult. Symptoms include cough, phlegm production, wheezing and shortness of breath. COPD is a lifelong condition and has a progressive course. Although smoking is the most important risk factor, other environmental factors may also play a role in the development of this disease. COPD management includes a variety of strategies, such as medication, respiratory therapies, and lifestyle changes, which help patients control symptoms and improve their quality of life.

Lung cancer is a type of cancer that occurs as a result of the uncontrolled growth of cells in the lung tissue. This type of cancer, which is generally associated with smoking, does not cause symptoms at first and is usually noticed when it progresses. It may show symptoms such as shortness of breath, cough, bloody sputum, and weight loss. Early diagnosis is important because treatment options can often be limited once lung cancer is advanced. Apart from smoking, environmental factors such as air pollution and radon gas can also increase the risk. Treatment includes methods such as surgery, radiotherapy, chemotherapy and immunotherapy. Lung cancer is an important health problem due to its generally aggressive course, and efforts are made to combat it with early diagnosis and effective treatment approaches.
