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.

Doctoral students explore alternative methods for detecting skin cancer

An early diagnosis is crucial to be able to treat skin cancer before it spreads. But are there simpler methods that do not require taking a traditional tissue sample? Doctoral students from Malmö University have tested and explored various alternative methods with promising results.

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.

Exploring Populations of B and T Cells in Lymph Nodes of Patients Diagnosed with COVID-19 via Microscopy and Image Analysis

My work is focused on looking at the dynamics of B/T cell populations within lymph nodes from patients that had recovered from COVID-19. My role in this research was developing and implementing microscopy image analysis techniques using methods and instrumentation in part supplied by TissueGnostics.
