Lung cancer is having a malignant tumor in the lungs especially in the cells lining air passages.
Primary tumor-related signs and symptoms are cough, dyspnea, hemoptysis, and chest discomfort.
Signs and symptoms due to intrathoracic spread may involve the nerves (hoarseness, dyspnea, muscle wasting of upper limb, Horner's syndrome), chest wall and pleura (chest pain, dyspnea) and vascular structures (facial swelling, dilated neck veins, cardiac tamponade) & viscera (dsyphagia).
The signs and symptoms due to metastatic spread are bone pain with or without pleuritic pain, neurologic symptoms, limb weakness, unsteady gait, cervical lymphadenopathy, and skin nodules.
Due to the apparent risk of adverse outcomes of disease and adverse events (AEs) associated with short-acting beta-agonists (SABA), the Global Initiative for Asthma (GINA) 2019 guideline recommends that all patients with mild asthma should receive symptom-driven or regular low-dose inhaled corticosteroid (ICS)−containing controller treatment.
