Types of Biopsies
Skin biopsy
Skin biopsies are performed to study skin lesions or diseases that may affect them. The lesion can be removed completely or, if large, take just a bit.
A local anesthetic is administered and then cut a piece of skin with a scalpel. Finally, the skin is sewn with a couple of points. In this way a scar is very small, barely visible.
Node biopsy
The lymph nodes are small bumps where the immune system protects us from attacks such as infections or tumors. Their study when they are enlarged allows us to study many diseases. Usually found in the neck, armpit.
For the biopsy a small incision under local anesthesia and was sidelined until the lymph tissues and removed. This is a fairly simple procedure that the surgeons practiced frequently and usually has few complications. Sometimes punctured before deciding node biopsy.
The node removed can be studied to look for different infections or to diagnose a tumor. However, the vast majority of nodes are affected by infections trivial and should not be touched. Only when they are greatly enlarged or persist too long the doctor will puncture or biopsy of the nodule.
Breast Biopsy
This type of biopsy is performed when clinical examinations in the ultrasound or mammography is suspected of a lump or tumor in the breast. A biopsy can determine the malignancy of the tumor.
