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 shows glomerulonephritis after SARS-CoV-2 mRNA vaccination likely coincidental

In a recent study posted to the medRxiv* pre-print server, researchers assessed whether messenger ribonucleic acid (mRNA)-based coronavirus disease 2019 (COVID-19) vaccines increase the incidence of glomerulonephritis against the null hypothesis stating any observed temporal association between the two phenomena was purely coincidental.

MAPK pathway mutations can provide “precision” treatment targets for head and neck cancer

About one-fifth of often deadly head and neck cancers harbor genetic mutations in a pathway that is key to normal cell growth, and scientists report those mutations, which enable abnormal cancer cell growth, can also make the cancer vulnerable.
