In most cases, doctors need to do a biopsy to diagnose cancer. A biopsy is a procedure in which the doctor takes a tissue sample. A pathologist then looks at the tissue under a microscope and runs other tests to see if the tissue is cancerous. Pathology reports play an important role in diagnosing cancer and helping to decide treatment options.
Types of tumour biopsy:
- Incisional biopsy: only a sample of tissue is removed
- Excisional biopsy: entire lump or suspicious area is removed
- Fine needle biopsy: a sample of tissue or fluid is removed with a needle
- Endoscopic biopsy: an endoscope is used to remove tissue
- Bone marrow biopsy: a large needle is used to enter the pelvis bone to collect bone marrow.
