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.

Researchers identify a driver of drug resistance in some cancers

Patients with BRCA1/2 mutations are at higher risk for breast, ovarian and prostate cancers that can be aggressive when they develop - and, in many cases, resistant to lifesaving drugs.

Detection of cancer using different kind of liquid biopsy

Because cancer is easier to successfully treat when it's caught early, a major goal in cancer research is to develop new ways to find tumors at early stages, before they start to spread. One approach that's being studied are liquid biopsies.

Triple-negative breast cancer's ecosystem reveals potential therapeutic targets

Researchers from the Garvan Institute of Medical Research have uncovered four new subtypes of cells within triple-negative breast cancer, which contain promising new therapeutic targets for the aggressive disease.

Enzyme in the gut could provide a useful biomarker for intestinal diseases

Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases, according to new research published in Nature Communications.

Researchers develop new method to diagnose brain tumor without incisions

Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's poor health conditions.

Deep learning algorithm can infer molecular alterations in cancer from histology images

Researchers at the University of Chicago Medicine Comprehensive Cancer Center, working with colleagues in Europe, created a deep learning algorithm that can infer molecular alterations directly from routine histology images across multiple common tumor types.

Less invasive imaging system can improve cancer diagnosis

Cancer diagnosis requires a lengthy process of multiple analyses of tissue biopsies, impeding the quick and early detection of cancers.

Study shows how the immune system attacks harmful viruses and bacteria

A new study has revealed how immune cells migrate to the lymph nodes and help attack harmful viruses and bacteria.

Gene biomarker can distinguish between atopic dermatitis and psoriasis with 100% accuracy

Mount Sinai researchers have pinpointed a single gene biomarker, nitride oxide synthase 2 (NOS2) that can distinguish atopic dermatitis (AD) and psoriasis with 100 percent accuracy using adhesive tape strips, a non-invasive alternative to skin biopsy.

Rare inherited mutation in TP53 gene predisposes to a wide range of cancers

Rare inherited mutations in the body's master regulator of the DNA repair system – the TP53 gene – can leave people at a higher risk of developing multiple types of cancer over the course of their lives.

MRI Scan Used For Heart Disease Could Also Pick Out Aggressive Cancers

An MRI scan used for heart disease could help assess whether children's cancers are especially aggressive and spot early signs that treatments are working.

Diagnosing Brain Tumors With A Blood Test

A highly sensitive blood test has been found to accurately diagnose and classify different types of brain tumors, resulting in more accurate diagnosis.

'Lab-on-a-chip' technology accurately detects early and advanced breast cancer

A scalable "lab-on-a-chip" technology based on inkjet printing methods detected breast cancer in plasma samples from patients with more than 90% accuracy, according to a new study.

New technique enables high-resolution visualization of tumor heterogeneity patterns

Malignant tumors consume nutrients and oxygen faster than healthy cells. To do so, they recruit blood vessels in their environment.

New minimally invasive method allows cells to be sampled over time

At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene profiling or protein analysis destroy the cell, study is confined to just that one moment in time, and researchers are unable to return to the cell to examine how things change beyond that snapshot.
