Is A Lapriscopy Biopsy Usually More Accurate Than A Needle Biopsy
A needle biopsy (or fine needle aspiration) is a procedure whereby a thin needle (similar to one the is used for drawing blood), is guided into a lesion and cells are obtained and then placed immediately onto a glass slide for evaluation under the microscope. Unlike a biopsy where "chunks" of tissue are obtained, a fna often obtains only several drops of fluid that ...Read more
Apples N' Oranges: A biopsy is usually performed for tissue diagnosis of a tumor. The best method of biopsy (bx) is the safest, least invasive means to reach this dx. Therefore, the specific technique is based on what is being bx'd & where it's located. In the abdomen, most tumors can be bx'd by (ct or ultrasound-guided) needle bx. Rarely, laparoscopy may be necessary if tumor cannot be seen radiologically. ...Read more
Very Accurate: An article from baylor in 2000 looked at more than 6000 patients who underwent thyroid fna biopsy. Sensitivity and specificity values of thyroid fna were 93% and 96%. The current nci classification: 1) nondiagnostic fna samples, 2) benign lesions, 3) malignant lesions, 4 atypia/follicular lesion of undetermined significance, 5) suspicious for a follicular lesion. Most common result benign. ...Read more
Digital mammogram: For general screening, mammograms, while imperfect, remain the best tool and digital mammograms are better at "seeing through" breast tissue. A mammogram is more likely to miss cancers in women with dense breast tissue and young women. Ultrasound is most often used with mammogram either to help characterize abnormalities seen on mammogram or to aid in finding abnormalities in dense breast tissue. ...Read moreSee 2 more doctor answers
More info in biopsy: Urine cytology examines single cells that are shed from the bladder lining and are suspended in fluid. Nuclear features of each cell can be evaluated but low grade cancer may look similar to reactive changes. A biopsy is a whole piece of tissue. The entire thickness of the lining and overall morphology can be evaluated. A biopsy is far better than urine cytology, especially for low grade lesion ...Read more
Excisional: Excisional biopsy is more accurate for diagnosis of lymphoma, because the samples are much larger. Fine needle aspiration (fna) can make the diagnosis, and is much less invasive - however, the sample is much smaller, and can miss the involved portion of the lymph node. ...Read moreSee 1 more doctor answer
Breast cyst aspiration had no fluid and core biopsy performed. Is it a cyst or a solud mass? More apt for cancer?
Which test is recommended for checking that prostate cancer is organ-contained? A needle biopsy or a Trans-rectal MRI?
Radiography: Needle biopsy will only reveal tumor cells within the prostate gland. Usually, multiple core biopsies are obtained as cancer cells can be scattered throughout the prostate gland. To determine if the cancer has spread beyond the prostate locally, transrectal ultrasound or MRI would be more appropriate. To evaluate for metastatic disease, CT or PET scanning would be modalities of choice. ...Read moreSee 1 more doctor answer
Is one biopsy reliable to diagnose a merkel cell carcinoma or since it's so rare another biopsy is recommended for a second opinion?
Size: A needle-directed biopsy means a hollow needle is stuck into a tumor or lymph node, and only the amount of tissue that fits inside the needle is removed. A sentinel node biopsy removes several lymph nodes entirely and the entire lymph node is examined under the microscope. A sentinel node biopsy requires an injection ahead of time to see which nodes are first in the chain of lymph nodes. ...Read moreSee 2 more doctor answers
My PSA is a 5, I'm going for a ultrasound guidance prostate biopsy. Is this procedure painful. Is it necessary?
Await biopsy results: Psa is a marker for prostate cancer, but it is not very specific, since it can be elevated in enlarged prostates or infections. For this reason, we try not to cause undue anxiety with a prediction. Risk calculators do exist, based on the results of 5, 519 men from the placebo arm of the pcpt trial. A version can be found at: http://deb.Uthscsa.Edu/uroriskcalc/pages/uroriskcalc.Jsp. ...Read moreSee 2 more doctor answers
Skin biopsy: This really depends on what is being biopsied. For a "nodule" or "bump," to rule out cancer, a biopsy is usually likely to give a very accurate diagnosis, although some early forms of cancer can be difficult. Biopsies of "rashes" are more tricky. Sometimes the histology is classical, and a very specific diagnosis can be made. But sometimes the biopsy has a non-specific appearance. ...Read more
Had a biopsy on a mass in post nasal space. Awaiting result. This is highly likely to be cancer isn't it?
Wait for pathology: You will have to wait for pathology for definitive diagnosis. Relax now. Remember to follow your doctor for final result and recommendation. ...Read more
Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more
Laparoscopy involves placement of a small camera-scope into the abdominal cavity, most often at the belly button. This allows us to see and surgically rx many abdominal and pelvic diseases. This is combined with distinction of the abd cavity with co2 gas to create more space to work. This usually requires a general anesthetic, yet most people can go ...Read more
