Misconceptions About Biopsies You Must Be Aware Of

1.Liquid biopsies are non-invasive 

Distinctive cancer mutations can be identified in fragments of DNA in a patient’s blood; what’re known as liquid biopsies which remove the need for traditional biopsies involving invasive surgical procedures. The term liquid covers specimens other than tissue that is . These include blood, urine, cerebrospinal fluid and fluid removed for bone marrow biopsies for investigation of blood cancers. Describing a bone marrow biopsy as non-invasive may generate surprise in patients who have had them. Performed under local anaesthetic they involve extracting both a portion of bone marrow and a tissue sample. 

2. Surgical breast biopsies are more accurate and less painful than less-invasive stereotactic breast biopsies guided by X-ray 

Not true, in accord with research. Stereostatic biopsies, which include a tiny incision, have been found to be at least of equal accuracy to surgical biopsies. They’re less invasive, less painful and cheaper. Nearly all women report little or no pain without any scarring on the breast, although there are always small dangers with any needle test, like bleeding, bruising and soreness. Very infrequently an infection might happen. The procedure involves local anaesthetic to numb the skin. 

3. A biopsy is essential if cancer of the prostate is suspected 

Not correct. A study of 576 men reported this year in The Lancet concluded that initial MRI scans could reduce over-diagnosis of harmless cancers by 5 percent, prevent one in four men using a pointless biopsy and improve detection of cancers in 48 to 93 percent. Biopsies can be inaccurate because tissue samples are taken randomly, while scans help to differentiate between aggressive and harmless cancers. Scans were found to have correctly diagnosed virtually all the aggressive cancers (93 percent) whilst the typical so-called TRUS biopsy correctly diagnosed only half (48 percent). 

4. A needle biopsy can disturb cancer cells, causing them to travel to other portions of the Human Body 

There’s no evidence that biopsies spread cancer cells. In fact, it’s crucial to perform a biopsy on almost any lumps to see whether they’re cancerous. Surgeons take precautions to prevent cancer cells from spreading during both biopsies and operations. For instance, in carrying tissue from one or more area of the body, they use different tools for every one. If a diagnosis is made, the tumor is removed surgically by taking a surrounding margin of normal tissue. 

5.Biopsy indicating clips are “processors ” which will track a patients’ whereabouts and stop entry through airport security 

Clips are used in breast biopsies to present markers to identify areas from where tissue has been removed. Made from titanium, the identical metal used in stylish and knee-joint replacements, these clips are the size of sesame seeds and therefore are seldom felt. They don’t set off metal detectors and can not be used as tracker devices. Allergic reactions are rare. Clips are inserted into the breast towards the conclusion of the biopsy and show up on future mammograms.
