Biopsy News and Research

RSS

Biopsy is the removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.

Getting second opinion from pathologists can help improve reliability of melanoma diagnoses

Getting a reliable diagnosis of melanoma can be a significant challenge for pathologists. The diagnosis relies on a pathologist's visual assessment of biopsy material on microscopic slides, which can often be subjective.

Survey quantifies cancer patients' interest in pathology services

Some of the most important players on a cancer patient's health care team are people they typically never meet or interact with - the pathologists who evaluate their tissue samples to determine the type and stage of disease they have.

Patients' blood samples and biopsies reveal secrets of lung cancer spread

Early signs that a patient’s lung cancer may spread and become untreatable can be picked up in samples of their blood and tumor, according to a trio of papers published in Nature Medicine today (Monday).

New insight into meningioma - possibility of targeted therapy

A new study published in the journal Oncotarget shows that certain mutations in the brain tumor called meningioma may help identify patients who have a better chance of recovery. This could help physicians make better clinical decisions based on more accurate diagnoses. It has also unveiled some of the genes that go wrong in meningiomas, as well as showing how targeted therapy could one day help fight this tumor.
