Treatment for breathlessness in lung cancer

Breathlessness may relate to the cancer itself, treatment effects, infection, fluid around the lung, a narrowed airway or low oxygen. Other conditions can add to the sensation, including anaemia, asthma, COPD, bronchiectasis, acute bronchitis, angina or atrial fibrillation. The speed of onset, chest pain, cough, fever and oxygen level help the clinical team decide what needs attention first.

Tell the oncology or medical team about a change rather than adjusting treatment alone. They may assess oxygen, blood tests and the chest, then treat infection, anaemia, airway narrowing or fluid when present. Pursed-lip breathing, a cool fan across the face, an upright position and pacing activities can reduce distress. Prescribed inhalers, oxygen or other medicines should be used exactly as advised, with support from palliative care when symptoms remain difficult.

Seek urgent help for sudden or rapidly worsening breathlessness, blue lips, severe chest pain, fainting, new confusion, coughing blood, or swelling with breathing difficulty. Contact the cancer team promptly for a new cough, fever, wheeze, pain with breathing or a noticeable reduction in usual activity.

Ask what may be causing the change, whether your medicines or treatment need review, how to use oxygen or inhalers, and whom to call outside clinic hours.
