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.

Scientists identify novel small molecules that block human tumor cell growth

Researchers from the Cancer Institute at NYU Langone Medical Center have identified three novel small molecules that interrupt a crucial cellular communication pathway that regulates many aspects of development and cancer.

Researchers classify chronic ulcerative stomatitis as a new autoimmune disease

In the first study investigating the origins of a little-known condition called chronic ulcerative stomatitis, researchers at Tufts University School of Dental Medicine provide evidence that an autoimmune response contributes to the painful oral sores that characterize the disease. The study findings support the classification of CUS as a new autoimmune disease.

Normal breast cells provide an innate defense mechanism against cancer

It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer - healthy cells.

PSA velocity is a poor predictor of prostate cancer

Researchers at Memorial Sloan-Kettering Cancer Center have found that change in PSA levels over time — known as PSA velocity — is a poor predictor of prostate cancer and may lead to many unnecessary biopsies.

Gene expression changes in prostate tissue surrounding cancer lesions may allow prostate cancer diagnosis

Researchers have found that gene expression changes in prostate tissue surrounding cancer lesions may allow diagnosis of prostate cancer even if no cancer cells are present in biopsy tissue, according to study results published in Cancer Research, a journal of the American Association for Cancer Research.

Hope4Cancer offers gentle non-invasive therapies for patients with brain tumor

Linda Roberts was puzzled when her favorite food, chocolate ice cream, suddenly did not taste good, and her prized orchids didn't smell nice either. When she began having sudden, severe headaches, she mentioned the changes in taste and smell to her doctor. After several tests, Roberts was diagnosed with a glioblastoma multiforme, the most aggressive form of brain tumor.

Scientists identify biological pathways that mediate IgA nephropathy

For the first time, researchers have found five regions in the human genome that increase susceptibility to immunoglobulin A nephropathy, a major cause of kidney failure worldwide - systematically identifying those that point to a tendency for IgA nephropathy, or a protection against it.

Study shows immune therapy can prevent pregnancy in mammals including humans

Researchers at Weill Cornell Medical College have shown that it is possible to immunize mammals to control fertility. They say their technique could possibly be used on other mammals -- including humans -- because fertility hormones and their receptors are species-non-specific and are similar in both females and males.
