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.

Surgery can be beneficial for one type of primary central nervous system lymphoma

Through a systematic review of published studies going back 50 years, Johns Hopkins Medicine researchers say they have identified a distinct subtype of primary central nervous system lymphoma that should be considered for surgical removal, suggesting a major shift in how this type of tumor is evaluated and managed.

New laboratory test has potential to accurately predict spread of breast cancer

Researchers at The Johns Hopkins University and other institutions report that a new laboratory test that induces cancer cells to squeeze through narrow spaces has the potential to accurately predict which breast cancers and other solid tumors are likely to spread, or metastasize, to other sites.
