Stage 3 lung cancer: what to know

Stage 3 is divided into subgroups because tumours can differ in size, position and the lymph nodes involved. The report may also identify non-small-cell or small-cell lung cancer and describe molecular or immune features. These details influence whether surgery, radiotherapy, systemic treatment, or a combination is considered.

Doctors may use chest imaging, tissue testing, breathing tests and other scans to understand the disease and whether treatment is feasible. A hoarse voice can occur when nearby nerves or structures are affected, but a symptom alone cannot establish the cause.

Ask whether Genomic Tumour Profiling is suitable, because tumour biology can affect systemic treatment choices. Depending on the findings, the team may discuss Chemotherapy, Radiotherapy, Lung Lobectomy or another operation, and supportive or Palliative Care for symptoms and quality of life.

Bring a list of medicines and supplements, smoking history, breathing changes and activity limits. Ask how treatment could affect cough, breathlessness, appetite, energy and work, and whether a respiratory or rehabilitation assessment would help.

Seek urgent medical help for severe or rapidly worsening breathlessness, blue lips, new confusion, fainting, coughing up a large amount of blood or chest pain that does not settle. During treatment, contact the oncology team promptly for fever, chills or a sudden decline, even if symptoms seem mild.

Which stage 3 subgroup and lung cancer type do I have? What do the scans show about lymph nodes and nearby structures? Has the tumour been tested for biological features? Is surgery possible, and what would the sequence of treatments be? What symptoms should trigger a same-day call, and who is the out-of-hours contact?
