The prostate is a male organ that is located at the outlet of the bladder, just in front of the rectum. You can play by introducing the finger into the rectum (DRE) and can be viewed using a special type of ultrasound device adapted for use within the rectum (transrectal ultrasound TRUS). These scanners also allow to adapt a needle biopsy is obtained while observing the injury.

The biopsy is usually indicated when a lesion has been noted in a rectal prostate or transrectal ultrasound performed in connection with high blood levels of PSA (prostate specific antigen) being observed. Read the rest of this entry »

The gastrointestinal tract starts at the mouth to the anus through the esophagus, stomach, small intestine, large intestine and rectum. All except the small intestine, where it is also extremely rare that there are malignant tumors, are accessible to biopsy with the help of endoscope.

The endoscope is a tube in which they incorporated a video camera, a light and a channel through which they work and obtain biopsies. Most are flexible and can circumvent the angles of the digestive tract. When the endoscope inserted through the mouth or anus (colonoscopy or sigmoidoscopy then called, according to the length) leads to the lesion to be analyzed and through the working channel is introduced a clip that grasps the tissue sample.

Curettage of the uterus is a way to get tissue from the endometrium (the innermost layer of the uterus) for microscopic study. Diagnose hormonal changes, polyps or find evidence of tumors. It is done when the rhythms are menstrual disturbances, irregular vaginal bleeding or changes in exploration or in radiological studies (mainly ultrasound) that require a pathological study to know the origin. Curettage is also used to stop bleeding when it is abundant in abortions or to remove retained products.

To do so is usually general or spinal anesthesia. First open the cervix through a series of dilators (rod-shaped) having a progressively increasing diameter until it reaches sufficient size to introduce the knife with which to obtain the tissue. Complications are rare and most important is the possibility of perforating the uterus by introducing the dilators or the curette. Read the rest of this entry »

At present there are many possibilities for biopsy of lesions in the breast, which are applied depending on the type of alteration is found and the options available in the center where the study is conducted (usually at the center has no time for all techniques, but a combination of them). The possibilities are:

FNA (fine-needle aspiration with fine needle)

Usually used in palpable lesions (which can be played while browsing the breast). Lets get a Pap test and see if there is malignant or not, but lets you know what kind of tumor it is. It’s less annoying for being a needle very finite, so is often used to be safer when you consider that the tumor is benign.

Needle biopsy tru-cut type

Allows for multi-cylinder of tissue for study, but requires local anesthesia and a small incision. With the material obtained can determine if the tumor is malignant and the type of tumor. Commonly used in easily palpable tumors and suspicious-looking to be cancerous. Read the rest of this entry »

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. Read the rest of this entry »

What is a biopsy?

A biopsy is the removal of a sample of body tissue for examination. These samples are studied under a microscope (disease or pathology) to aid in diagnosis. Sometimes only a few cells are obtained by vacuuming or brushing. This is called cytology and is less aggressive, but provides less information and may not be enough.

Biopsies can be of several types:

Open surgical

When conventional surgery is performed by making an incision in the skin. Can be performed with local or general anesthesia depending on the area that requires analysis. Lets take part as a sample or remove the entire lesion. Read the rest of this entry »
