Biopsy is an invasive medical procedure in which sample of a tissue is removed from the body for examination. The tissue is examined by a pathologist (a doctor, who specialises in diagnosing diseases by looking at cells and tissues under a microscope) under a microscope. This can help to diagnose the underlying pathology or disease. As the sample is analysed under a microscope, very small samples are needed.

After sample of tissue is taken by biopsy, it is preserved and delivered to a pathologist. A pathologist is a doctor, who specialises in diagnosing diseases by looking at cells and other tissue samples under a microscope or by other tests. The time taken for the biopsy results to come can vary. When a surgical biopsy is done, the pathologist may read a biopsy and report back to surgeon within a few minutes. The final biopsy report may come after a week or longer. Your doctor will discuss the result of biopsy on follow-up and then recommend appropriate treatment.
