Type of Biopsy: Prostate Biopsy
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 »
Type of Biopsy: Endoscopic Biopsy (Digestive Tract)
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.

Type of Biopsy: Endometrial Biopsy (Uterine)
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 »
