They also examine cells in bodily fluids (cytopathology) such as urine, and also in large specimens, for example from surgery for bowel or breast cancer. This often means that a definite diagnosis is made. If it is, the aim is to identify the nature of the problem. The slices are stained to show different parts of the cells and examined under a microscope to see whether the tissue is abnormal. These small pieces are treated with chemicals so that very thin slices can be cut. The histopathologist examines tissue biopsies with the naked eye to look for any visible abnormalities and to select pieces to examine in more detail under the microscope. Histopathologists examine biopsies (tissue or cells) removed from patients in the clinic or during an operation. Histopathologists are also at the forefront of research into many common diseases such as cancer. Some histopathologists also carry out autopsies (post-mortems) to find out why someone has died. Histopathologists are the doctors who diagnose cancer and other serious illnesses – but they also often have good news, for example discovering that a lump or mole is completely benign. There are various types of biopsy that can be used to help identify a wide range of health conditions. How a biopsy is carried out will depend on from where the tissue sample is being taken.Īn operation can start with a biopsy with the sample being tested straight away so that the surgeon can carry out appropriate surgery using the diagnosis provided.įind out what happens when a biopsy gets sent to a lab The role of the histopathologist Ruling out a diagnosis is much more difficult and may require several tests including multiple biopsies. It is impossible to be sure whether a lump or growth on the skin or inside the body is cancerous (malignant) or non-cancerous (benign) just by looking at it or feeling it.Ī biopsy can provide this information. ![]() For example, the results of a biopsy can show how severely an organ, such as the liver, is inflamed. endometriosis – where cells that usually line the womb are found elsewhere in the bodyīiopsies can be used to investigate the cause of a person’s symptoms or to help diagnose a number of different health conditions. Where a condition has already been diagnosed, a biopsy can be used to measure how severe it is or at what stage it is.peptic ulcers – ulcers affecting the digestive system.Biopsies can often help diagnose or rule out: ![]()
