Biopsy News and Research RSS Feed - Biopsy News and Research

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.

Study reveals impact of histology on SBRT treatment in early-stage NSCLC patients

Study reveals impact of histology on SBRT treatment in early-stage NSCLC patients

Early-stage non-small cell lung cancer (NSCLC) patients with squamous cell carcinoma (SqCC) have a significantly higher rate of local failure after stereotactic body radiation therapy (SBRT) than other NSCLC histological subtypes. [More]
Oncotype DX test can help guide treatment decisions and enable personalized care before breast cancer surgery

Oncotype DX test can help guide treatment decisions and enable personalized care before breast cancer surgery

New data presented at the 2016 San Antonio Breast Cancer Symposium (SABCS) demonstrate that analyzing tumor biology with the Oncotype DX test can identify patients unlikely to benefit from chemotherapy prior to breast cancer surgery (neoadjuvant setting) and guide treatment decisions without compromising outcomes.

U-M researchers identify gene expression linked to gender differences in autoimmune diseases

U-M researchers identify gene expression linked to gender differences in autoimmune diseases

Women represent nearly 8 out of every 10 people with autoimmune diseases. Although the statistics are well-known, the scientific community is still trying to figure out why women's immune systems are more likely to become overactive and attack their own healthy cells. [More]

High levels of enzyme can predict memory impairment and Type 2 diabetes

An enzyme found in the fluid around the brain and spine is giving researchers a snapshot of what happens inside the minds of Alzheimer's patients and how that relates to cognitive decline. [More]
How to stay safe in the sun

How to stay safe in the sun

When choosing a sunscreen, you must first consider what you will be doing when wearing it, for example if you're running, the sunscreen you choose must be able to withstand sweating. [More]
Study shows the use of Renishaw inVia™ microscope in prostate cancer detection

Study shows the use of Renishaw inVia™ microscope in prostate cancer detection

New research at the Guangdong Medical University suggests a laser-based approach could be the latest breakthrough in prostate cancer detection. The proposed non-invasive blood test uses a combination of two techniques: surface-enhanced Raman scattering (SERS) and a new mathematical analysis technique called support vector machine (SVM).

WPI researchers develop chip to trap and identify metastatic cancer cells in blood

WPI researchers develop chip to trap and identify metastatic cancer cells in blood

A chip developed by mechanical engineers at Worcester Polytechnic Institute can trap and identify metastatic cancer cells in a small amount of blood drawn from a cancer patient. [More]
New technique uses focused ultrasound to detect cancer biomarkers in the blood

New technique uses focused ultrasound to detect cancer biomarkers in the blood

Each year, thousands of Canadian men with prostate cancer undergo biopsies to help their doctors better understand the progression and nature of their disease. It provides vital, sometimes life-saving information, yet cancer researcher John Lewis knows it can be a difficult test to ask of anyone. [More]
