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.
The human immune system is notably adept at evading tumor cells, which construct physical barriers, adopt masks, and restrain the immune system with molecular ploys.
Heart damage is prevalent in COVID-19 patients, leading many to doubt how the virus impacts the heart.

Depixus®, a biotechnology company, today announces it has raised EUR 30.6 million in an oversubscribed Series A financing.
Tumors are heterogeneous, which means that different parts of the same tumor can be genetically distinct. This phenomenon, known as intratumor heterogeneity, is steadily gaining in significance within the field of cancer research.
Scientists recently created a technique to accurately and quickly correct genetic alterations in the cultivated patient cells.
Helicobacter pylori (H. pylori) is one of the most common bacterial infections worldwide, affecting more than 40 % of the population and is one of the causes of digestive symptoms, such as epigastric discomfort, heaviness or bloating of the stomach, or of other more serious diseases, such as the development of gastric and duodenal ulcers, gastric lymphoma or gastric cancer.
Researchers have developed a model that could predict early on in treatment whether cancer patients will respond to immunotherapy, according to a report published today in eLife.
