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.

May hepatic granulomas be part of the histological spectrum of chronic hepatitis C?

While older large series of patients with hepatic granulomas have found sarcoidosis and tuberculosis to be the most common causes of hepatic granulomas, recent works have noted some patients with chronic hepatic C and hepatic granulomas and no other obvious associations.

Trial looks at high intensity focused ultrasound for locally recurrent prostate cancer

A Phase III clinical trial at New York University is investigating the safety and efficacy of High Intensity Focused Ultrasound (HIFU) for the treatment of locally recurrent prostate cancer following failed external beam radiation therapy (EBRT) using the Sonablate(R) 500.

Computer-aided detection (CAD) mammography for breast cancer screening

Computer programs designed to help radiologists could identify more cases of breast cancer, but they might also increase the number of false-positive results, which can lead to biopsies in healthy women, according to a recent systematic review.

Having dense breasts increases breast cancer risk

Having dense breasts - areas that show up light on a mammogram - is strongly associated with increased breast cancer risk, but "why" remains to be answered.

Magnetic resonance imaging alternated with mammography may be best for high-risk women

Magnetic resonance imaging (MRI) alternated with mammography at six-month intervals can detect breast cancers not identified by mammography alone, a research team from The University of Texas M. D. Anderson Cancer Center will report at the 31st at the CRTC-AACR San Antonio Breast Cancer Symposium.

Molecular breast imaging technique shows greater sensitivity over mammography, ultrasound and MRI for difficult to diagnose breast cancer

Breast-Specific Gamma Imaging (BSGI) has been proven to be a highly sensitive imaging technique for the diagnosis of invasive lobular carcinoma (ILC), a difficult to diagnose breast cancer.

European research effort pushes towards cervical cancer cure

Every year, tens of thousands of women die in the EU from cervical cancer because the disease is not detected and treated at an early enough stage. A multidisciplinary European research effort plans to change that.

Bariatric surgery may resolve liver disease

Obesity is a growing epidemic in the U.S. with a significant increase in prevalence from 15 percent to 32.9 percent from 1980 to 2004. Nonalcoholic fatty liver disease (NAFLD) is an emerging problem related to the obesity epidemic, becoming one of the most common causes of liver disease in the nation.

New method could help reduce breast-lesion biopsies

A new method of characterizing breast lesions found during an MRI exam could result in fewer biopsies of benign tumors with the benefits of reduced pain and expense for patients and providers, according to a paper that will be presented today (Sunday, Nov. 30) at the annual meeting of the Radiological Society of North America (RSNA).

Mammogram most effective 12 months after radiation

Breast cancer patients who receive breast-conserving therapy and radiation do not need a follow-up mammogram until 12 months after radiation, despite current guidelines that recommend follow-up mammograms at between six and 12 months after radiation, according to a November 15 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.
