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.
Initial acute respiratory illness (ARI) admissions related to human adenovirus (HAdV), human metapneumovirus (hMPV) and human rhinovirus (HRV) occurring during early infancy increase the risk of subsequent ARI-related readmission, a recent study has shown.
Getting vaccinated against influenza can improve survival of patients with heart failure (HF), with earlier and more frequent vaccination being associated with a greater protection against deaths from cardiovascular (CV) events or any cause, a large Danish nationwide cohort study shows.
