Stage 4 non-small-cell lung cancer symptoms

A tumour in or near the lung may cause a persistent cough, chest discomfort, wheezing, or shortness of breath. Fluid around the lung can make breathing harder. Spread to bones may cause local pain, while involvement of the brain or nerves can lead to headaches, weakness, balance problems, confusion, or seizures.

Tiredness, reduced appetite, weight change, and sleep disruption can result from the cancer itself or from treatment. Symptoms can change over time, so a new symptom is worth reporting even if it seems mild.

Tell the oncology team when a symptom began, what makes it better or worse, and whether it limits walking, eating, sleeping, or speaking. Assessment may include examination, scans, oxygen checks, and review of tumour markers or molecular features. Immunotherapy or targeted therapy may be options for some tumour profiles; radiotherapy can help selected areas, including a painful or troublesome site.

Use prescribed inhalers, oxygen, pain relief, or anti-sickness medicines exactly as directed. Pace activity, rest between tasks, and ask for help with meals and transport when energy is low.

Seek emergency help for severe breathlessness, blue or grey lips, chest pain, coughing large amounts of blood, a seizure, sudden confusion, new one-sided weakness, or inability to stay awake. Call the treatment team promptly for fever, worsening cough, new pain, or rapidly increasing breathlessness.

Which symptoms are likely from the lung cancer and which could be treatment effects? Do I need molecular testing to guide treatment? What should I do if my breathing worsens at home? Could radiotherapy help a specific area? Who is available overnight or on weekends?
