A biopsy, in medical terms, is the removal of cells or tissues from a living person for examination. This examination is typically conducted by a pathologist to determine the presence or extent of disease, most commonly cancer. The tissue sample can be obtained through various methods, including surgical excision, needle aspiration, or scrape biopsy. The type of biopsy performed depends on the location and size of the suspicious area, as well as the suspected condition. Biopsies are a critical diagnostic tool, providing definitive information that guides treatment decisions.

The process of a biopsy involves collecting a small sample of the abnormal-looking tissue or fluid. This sample is then sent to a laboratory where it is processed and analyzed under a microscope. Pathologists look for any cellular abnormalities, such as unusual cell growth, inflammation, or the presence of cancerous cells. The results of the biopsy are crucial for confirming a diagnosis, staging a disease, and determining the most appropriate course of treatment. In some cases, a biopsy may also be used to monitor the effectiveness of treatment or to detect a recurrence of disease.

There are several types of biopsies, each suited to different situations. A fine-needle aspiration biopsy uses a thin needle to withdraw fluid or cells. A core needle biopsy uses a larger needle to extract a small cylinder of tissue. An incisional biopsy removes a portion of a larger lesion, while an excisional biopsy removes the entire suspicious area. Endoscopic biopsies are taken during procedures like colonoscopies or gastroscopies, allowing for examination of internal organs. The choice of biopsy technique aims to maximize diagnostic accuracy while minimizing patient discomfort and risk.
