Biopsy

What is a biopsy?

Biopsy – lifetime taking tissues, organs or cell suspensions for microscopic examination with diagnostic purpose. In a broader sense, a biopsy understand the process of study biopsy – tissue sections obtained in vivo. Biopsy is mandatory method of confirming the diagnosis in suspected the presence of cancer. A biopsy is the most reliable method of investigation in the case of the need to establish the cellular composition of tissue. Capture of tissues and their subsequent study under a microscope to determine the exact cellular composition of the investigated material. A biopsy is the study within the diagnostic minimum for suspected cancer, and is complemented by other research methods, such as radiological, endoscopic, immunologic.

What types of biopsies are there?

Classify types of biopsies by the method of taking tissue for research. In mammology most frequently used the following types of biopsies:

  • Excisional biopsy – a small diagnostic operation, which involves removing the entire organ under examination. In mammology excision biopsy is used to investigate the suspicious lymph nodes. It is used to obtain material for histological examination.
  • Incisional biopsy – a kind of biopsy, in which the study is taken only part of the organ or tissue. In mammology most often used this kind of incision biopsy as trepan-biopsy – biopsy using a thick needle and a special biopsy gun. It is used to obtain material for histological examination.
  • Fine-needle aspiration biopsy – one of the most frequently used in mammology varieties biopsy. Most often done using an ordinary medical syringes. This needle is introduced into the formation and investigated with the help of the vacuum created by a syringe researcher obtains a suspension of cells. The advantage of this method of biopsy is his quickness, indolence, and availability. Fine-needle aspiration biopsy can be performed under ultrasound. Disadvantage is the inability to obtain material for histological examination. This method provides only information about the cellular composition of education, but not about its structure and is only used for cytology.

Whether biopsy painful?

Fine-needle biopsy is usually almost painless.  Trepan-biopsy despite the relative pain has the advantage of speed – the fence material is instantaneous firing biopsy gun. Those types of biopsies, which are small operations, conducted under local anesthesia.
