Rare lung cancer: what to know

Rare lung cancer is not one single disease. It can describe an uncommon type, an unusual location, or a tumour with features that need specialist review. The name is confirmed through imaging, a biopsy when appropriate, and examination of tumour cells. Symptoms may include a persistent cough, breathlessness, chest discomfort, coughing blood, tiredness, or a [Hoarse Voice](/symptoms/hoarse-voice/); these symptoms can also have non-cancer causes.

Staging checks the size and position of the tumour and whether it has spread. Some lung cancers are assessed for changes in tumour genes or proteins, which may help guide treatment. If cancer has spread to the brain, this is called [Brain Metastases](/conditions/brain-metastases/). A specialist team may review the diagnosis before recommending treatment.

Ask for the exact tumour type, stage, and pathology findings in writing. Confirm whether the tissue is suitable for [Genomic Tumour Profiling](/treatments/diagnostics-and-staging/genomic-tumour-profiling/). Treatment may involve surgery such as a [Lung Lobectomy](/treatments/surgical-oncology/lung-lobectomy/), [Radiotherapy](/treatments/radiation-oncology/radiotherapy/), [Chemotherapy](/treatments/systemic-therapy/chemotherapy/), another medicine, or a combination. [Palliative Care](/treatments/supportive-and-palliative-care/palliative-care/) can help with symptoms and wellbeing at any stage.

Seek urgent help for severe breathing difficulty, coughing a large amount of blood, new confusion, a seizure, sudden weakness, chest pain, or fainting. Contact your oncology team promptly for fever during treatment, rapidly worsening breathlessness, or new neurological symptoms.

What exact type of lung cancer is present? What does the stage mean? Has the pathology been reviewed by a specialist? Is genomic profiling appropriate? Which treatments are being considered, and what are their practical effects? Who should I contact urgently if symptoms change?
