Biopsiaid

Biopsiaid are medical procedures in which tissue samples are removed from a living person for examination under a microscope. They are used to diagnose diseases, determine the nature of a lesion, and guide treatment. Samples can be taken from almost any organ, including skin, breast, liver, kidney, lung, and bone.

Common types include needle biopsies (fine-needle aspiration and core needle biopsy), incisional biopsies, excisional biopsies, and endoscopic or surgical biopsies. Imaging guidance with ultrasound, CT, or MRI is often used to improve sampling accuracy.

Before a biopsy, patients are informed about benefits and risks and must give consent. Local anesthesia is typical; sedation may be used for some procedures. After collection, samples are sent to a pathology laboratory for histology, cytology, or molecular testing.

Risks include bleeding, infection, pain, and injury to nearby tissues. There is also a possibility of sampling error or false-negative results, which may require repeat biopsy or additional tests.

Biopsiaid play a central role in cancer diagnosis and staging, as well as in investigating infections, inflammatory diseases, and organ rejection. They can also provide material for research and genetic testing.

The practice relies on informed consent, proper tissue handling, and careful interpretation by trained pathologists. Ethical considerations include patient privacy and appropriate use of tissue samples.
