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.

New theranostic reagent could improve detection and treatment of prostate cancer

A recently discovered prostate cancer-selective antigen has been identified as a useful molecular imaging target for the detection and targeting of metastatic prostate cancer lesions, as reported in the November issue of The Journal of Nuclear Medicine.

Nothing to sneeze at: The $2,659 bill to pluck doll’s shoe from child’s nostril

It was supposed to be a fun evening out for Katy and Michael Branson. But their 3-year-old daughter, Lucy, apparently had other ideas.

FDA-approved drug to prevent organ rejection may slow skin aging

The search for youthfulness typically turns to lotions, supplements, serums and diets, but there may soon be a new option joining the fray.

New technology may offer alternative means of profiling tissues

Current cancer treatment courses often begin with tissue biopsies. Biopsies, however, which involve the physical resection of a small tissue sample, can lead to localized tissue injury, bleeding, inflammation, and stress, as well as increased risk of metastasis.

Study: Many patients treated for iNPH also develop Alzheimer’s disease

Up to one in five patients treated for idiopathic normal pressure hydrocephalus, iNPH, also develop Alzheimer’s disease, according to a new study from the University of Eastern Finland and Kuopio University Hospital.

TSU researchers develop new approach to diagnose adenocarcinoma

Scientists have developed a new approach to the diagnosis of adenocarcinoma - a malignant tumor of the prostate gland. Artificial intelligence is used to determine oncopathology and determine the stage of the disease with this approach.

Lung inflammation in a case of a 16-year-old linked to vaping

The Centre for Disease Control and Prevention (CDC) has warned earlier last month about the possible risk of lung inflammation from the exposure to the fluid in e-cigarettes. Now a case of a 16-year-old boy was reported with life threatening lung inflammation leading to respiratory failure.

Botanical product kratom may cause liver toxicity and injury, study finds

Data from a new study presented this week at The Liver Meeting – held by the American Association for the Study of Liver Diseases – found that kratom, a popular and widely available product, may cause liver toxicity and severe liver injury.

CCNY researchers receive two U.S. patents for brain cancer-detecting innovation

Raising hopes of rapid and more specific brain cancer diagnoses, a new "Resonance Raman" technique developed by world-renowned physicist Robert R. Alfano and his IUSL research group at The City College of New York is the recipient of two U.S. patents.

Novel mouse model can help monitor kidney disease progression and perform drug screening

Chronic kidney disease affects 750 million people each year. Aging populations and an increase in diseases such as diabetes will lead to a greater burden of kidney disease.

Novel detection method for retinoblastoma

A retinoblastoma is a dangerous cancer often occurring in very young children, under 2, which can cause blindness or the loss of the eye. The tumor is a diffuse, gluey mass spread all over the eye. It also spreads easily. As a result of this, direct biopsy is impossible, unlike with most other tumors. Instead, eye examination by ophthalmologists (eye specialists) and ultrasound imaging are needed to make a diagnosis.

Penn researchers tag CAR T cells with imaging markers to monitor cancer therapy

With CAR T cell therapy, a patient's own immune cells are genetically modified and inserted back into the body to find and kill cancer. This form of immunotherapy has already revolutionized some cancer treatments, but once the CAR T cells are inside a patient, where do they go? How do doctors know that they have successfully reached their target and that they are continuing to fight disease weeks, months, or even years later?

Researchers discover way to find genetic tumor information of retinoblastoma

Retinoblastoma is a cancer that forms in the light-detecting cells in the back of the eye. It often appears in children under two years of age and can lead to blindness or eye removal. Most cancers are biopsied and studied so that medical research can design targeted treatments. Unfortunately, this is not possible with retinoblastoma.

Grief grew into a mental health crisis and a $21,634 hospital bill

Arline Feilen lost her husband to suicide in 2013. Three years later, she lost her dad to cancer. And this February, she lost her 89-year-old mom to a cascade of health problems.

New contrast agent improves MRI diagnosis of early liver fibrosis

A new compound has been invented to bind to liver cells that are in the early stages of damage, thus making it easier to pick them up using MRI (magnetic resonance imaging).

Liquid biopsy can predict prognosis in patients with glioblastoma

A blood test that measures the amount of cell-free DNA (cfDNA) in the bloodstream - called a liquid biopsy - correlates with how patients will progress after they are diagnosed with glioblastoma (GBM), the deadliest and most common primary brain tumor in adults.

MRI contrast agent enables early detection of liver disease

Researchers have developed a new MRI contrast dye that enables more accurate and safer detection of early-stage liver disease than currently approved agents.

Synthetic scaffolds could detect multiple types of cancers

Invasive procedures to biopsy tissue from cancer-tainted organs could be replaced by simply taking samples from a tiny "decoy" implanted just beneath the skin, University of Michigan researchers have demonstrated in mice.

California fires illuminate trauma and resilience

Dorothy Hammack had planned to wash her thick, dark hair in the kitchen sink Friday morning. She couldn't yet shower, due to the incision on her breast from a biopsy a few days before. Her doctor had already called to let her know the results: She had breast cancer.

Researchers use 3D electron microscopy to unravel dense networks in the cerebral cortex

Unlike any other organ, our brains contain extremely densely packed networks of membranous cables that are used by our about 86 billion nerve cells for communication amongst each other.
