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.

Study suggests routine evaluation does not predict prostate cancer

On the heels of the American Cancer Society's recent controversial response to breast and prostate cancer screenings guidelines, a new study from the Mayo Clinic has emerged analyzing the correlation between prostate-specific antigen (PSA) levels and prostate size. The study discovered that routine annual evaluation of prostate growth does not predict the development of prostate cancer.

UPMC reports 10,000th patient treated using Elekta's Leksell Gamma Knife system

On the morning of December 17, 2009, UPMC physicians used Gamma Knife® surgery to treat the center's 10,000th patient, an 81-year-old male with a tumor deep in his brainstem, a site where traditional surgery would have been impossible. Gamma Knife surgery is performed using Elekta's Leksell Gamma Knife system, which directs up to 201 pencil-thin beams of therapeutic radiation precisely on brain tumors and other targets in the head.

Baylor University Medical Center adds Naviscan PEM to its imaging services

The Baylor University Medical Center in Dallas has taken delivery of the Naviscan PEM scanner at its Darlene G. Cass Women's Imaging Center. Baylor will utilize PEM (Positron Emission Mammography) to complement their existing anatomical tools by providing a critical three-dimensional metabolic perspective of breast cancer. The metabolic view allows physicians to make the optimal cancer care decisions by providing an unprecedented ability to distinguish between benign and malignant lesions in what researchers call "specificity".

ARNMD meeting examines psychological and neurological aspects of PTSDs and traumatic brain injuries

War is hell, as the old saying goes -- with loss of life and limb, destruction of infrastructure and the environment, and devastating costs. Recent biomedical research has shed light on another pernicious consequence of military conflict: psychological and neurological conditions like post-traumatic stress disorder and traumatic brain injury. At the same time, researchers have worked to uncover some of the motives and meanings of war.
