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.

Physicians trained in dermatoscopy can improve odds for early detection of melanoma

Primary care physicians trained in dermatoscopy can improve odds for early detection of melanoma while reducing the need for invasive biopsies, according to a study in The Journal of the American Osteopathic Association.

New treatment method for glioblastoma shows indication of benefit

Glioblastoma is an aggressive brain tumour that usually occurs in late adulthood. Just two years after diagnosis, only 13.6% of patients are still alive. Standard treatment consists of surgery, followed by radiation and chemotherapy.

PET/CT can aid in earlier diagnosis and treatment assessment of tuberculosis

Research presented at the Society of Nuclear Medicine and Molecular Imaging's 2019 Annual Meeting shows that molecular imaging with 18F-FDG positron emission tomography/computed tomography can evaluate tuberculosis at the molecular level, effectively identifying diseased areas and guiding treatment for patients.

Machine learning algorithms applied to biopsy images can improve gut disease diagnosis

A study published in the open access journal JAMA Open Network June 14 by scientists at the University of Virginia schools of Engineering and Medicine and the Data Science Institute says machine learning algorithms applied to biopsy images can shorten the time for diagnosing and treating a gut disease that often causes permanent physical and cognitive damage in children from impoverished areas.

Genetic study on liver iron content may pave way for better treatment

High levels of iron in the liver are linked to a number of serious health conditions including cancer, diabetes, high blood pressure and cardiovascular as well as liver disease. But measuring liver iron is difficult and until recently could only be done through an invasive biopsy.

New 'virtual biopsy' device developed to detect skin tumors

Using sound vibrations and pulses of near-infrared light, a Rutgers University scientist has developed a new "virtual biopsy" device that can quickly determine a skin lesion's depth and potential malignancy without using a scalpel.

UCLA physicians find more effective method for detecting prostate cancer

Each year, 1 million men in the U.S. undergo biopsies to determine whether they have prostate cancer. The biopsy procedure traditionally has been guided by ultrasound imaging, but this method cannot clearly display the location of tumors in the prostate gland.
