🫁 Common Conditions Associated With Lung Cancer
Lung cancer does not only affect the lungs — it can lead to several secondary conditions that impact breathing, movement, and overall quality of life.
Common conditions include:
• Shortness of breath (dyspnoea) – due to reduced lung capacity or airway obstruction
• Chest infections – such as pneumonia from impaired airway clearance
• Pleural effusion – fluid build-up around the lungs causing breathing difficulty
• Persistent cough – often dry or productive
• Fatigue and deconditioning – related to cancer itself and its treatment
• Muscle weakness and weight loss – due to reduced activity and systemic effects
• Postural changes and chest wall stiffness – affecting breathing mechanics
