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.

Less invasive lymph node biopsy method could spare thousands unnecessary operations

Barcelona, Spain: Using an ultrasound-guided fine needle to biopsy lymph nodes could spare thousands of melanoma patients every year worldwide from having to undergo unnecessary and sometimes unpleasant surgery to verify whether their cancer has spread, new research indicates.

PET scans accurately detect a breast tumor's response to chemotherapy

Researchers in Australia have shown that positron emission tomography (PET) that uses a radioactive sugar molecule is more useful than mammography and ultrasound in predicting a breast tumour's response to chemotherapy and, therefore, the patient's ultimate likelihood of survival.

Diet and medications may assist prevention of prostate cancer

Recent investigations of medications, diet and the molecular understanding of prostate cancer are defining potential prevention strategies for the disease, and herald a new stage in the management of this cancer, according to a new review.

Common abdominal pain may be due to a potentially treatable newly recognized inflammatory reaction

As many as one in four people in westernized countries experience pain or discomfort in their upper abdomen, and physicians have almost nothing to offer except anti-acid medicines, which usually don't work.

Chronic fatigue syndrome linked to enteroviruses

Chronic fatigue syndrome, also known as ME (myalgic encephalitis), is linked to a stomach virus, suggests research published ahead of print in Journal of Clinical Pathology.

Shrinkage of prostate led to overestimation of cancer risk in finasteride trial

Reanalysis of data from the first long-term randomized trial of a chemopreventive agent for prostate cancer shows that the excess prevalence of high-grade prostate cancer in the drug-treated group may be attributable to shrinkage of the prostate at the time of biopsy.

Scientists isolate stem cells in womb tissue

Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors.

New lung cancer guidelines say forget scans and chest X-rays

The American College of Chest Physicians (ACCP), is advising against low-dose CT scanning or chest X-rays to screen for lung cancer.

Generic prostate drug finasteride helps find high-risk cancers early

Men now have another good reason to consider taking finasteride, a well-known generic drug that shrinks an enlarged prostate and reduces the risk of getting prostate cancer by 25 percent.

Finasteride unlikely to induce high grade prostate cancers

An increase in high-grade prostate cancer among men taking the drug finasteride is likely caused by an increased detection of cancers, and not by the development of more high-grade cancers, according to two studies published online September 11 in the Journal of the National Cancer Institute.

Link between nicotine and atherosclerosis

It's well known that smoking cigarettes increases risk for a host of serious health problems from cancer to heart disease. Now a new study from Weill Cornell Medical College in New York City looks at how they do their dirty work by contributing to atherosclerosis, or hardening of the arteries. The evidence points to nicotine, the addictive chemical in cigarettes.

Myoendothelial cells identified as new human source of stem cells with potential to repair muscle

For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy.

Vaginal bleeding a sign of endometrial cancer

Women past menopause who experience any abnormal vaginal bleeding or spotting should contact their physician. It's one of the signs of endometrial cancer.

Discovery suggests location of genes for breast density, a strong risk factor for breast cancer

Studying the DNA of 889 people, gene hunters at the Mayo Clinic and H. Lee Moffitt Cancer Centers have identified a region on chromosome 5p that is significantly associated with dense breast tissue, a known risk factor for breast cancer.

Big leap in genomic screening of blood vessels from patient tissue

Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing.

Hypnosis session before breast cancer surgery aids recovery

Researchers say women who undergo surgery for breast cancer may be helped in the recovery process if they have a hypnosis session beforehand.

Scientists identifiy successfully reprogrammed cells by looks alone

Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait.

Reactivating a critical gene lost in kidney cancer reduces tumor growth

Researchers at Mayo Clinic Jacksonville, have found that a key gene is often silenced in clear cell renal cell carcinoma, the most common type of kidney cancer, and when they restored that gene in human kidney cancer cells in culture and animal experiments, tumors stopped growing and many disappeared.

Cases of stomach cancer to fall over next decade

New cases of stomach cancer are set to plummet a further 25 per cent in the West over the next decade, indicates research published ahead of print in the journal Gut .

New clues to why persistent acid reflux can turn into cancer

New research from scientists at UT Southwestern Medical Center and the Dallas Veterans Affairs Medical Center underscores the importance of preventing recurring acid reflux while also uncovering tantalizing clues on how typical acid reflux can turn potentially cancerous.
