Glossary
The glossary explains some of the words used across this website and covers some key cancer and research terms, which primarily focus on lung cancer.
Benign tumour
A growth of cells that are not cancerous. A benign tumour does not invade nearby tissue or spread to other parts of the body and is not generally considered harmful.1
See also ‘Malignant tumour’
Biomarker
Molecular indicators of an underlying condition or susceptibility for developing a disease.1 Biomarkers may be produced by the cancer tissue itself or by other cells in the body in response to cancer, and can be found in the blood, stool, urine, tumour tissue, other tissues or bodily fluids.2 They can also be used to see how well the body responds to a treatment for a disease.
Biopsy
A procedure in which samples of lung tissue are removed to determine if lung disease or cancer is present.3 It is one of several techniques used to diagnose cancer.
