These procedures are usually fairly quick and might take 15 to 30 minutes to perform, depending on the part of the body being biopsied. Typically, the biopsy sample is then saved in a special type of preservative and sent to the pathology lab for processing.
Most biopsies will only require local anaesthetic, which means you won't need to stay in hospital overnight. However, an overnight stay is sometimes required when the biopsy is carried out under general anaesthetic. After having a biopsy, you won't usually feel any pain.
Results from a biopsy are usually returned with 24 to 48 hours. Special biopsies performed during surgical procedures may take as little as 10 to 15 minutes. Depending on the type of biopsy, you may need to make a follow-up appointment with your doctor to discuss the results. Treatment depends on the diagnosis.
In most cases, biopsies are outpatient procedures, so you won't need to stay in hospital overnight. But occasionally some types of biopsy, such as those where a tissue sample needs to be taken from an internal organ, may require a general anaesthetic.
The results, called a pathology report, may be ready as soon as 2 or it may take as long as 10 days. How long it takes to get your biopsy results depends on how many tests are needed on the sample. Based on these tests, the laboratory processing your sample can learn if cancer is present and, if so, what type it is.
Needle biopsies are commonly used to remove a small sample of cells or tissue from the area of concern. If the cancer can't be diagnosed from a tissue sample, you may have surgery to remove the mass so it can be checked for signs of cancer. The biopsy results are used to diagnose and stage cancer.
Over one million people have breast biopsies each year in the United States. Approximately 20% of the biopsies reveal a breast cancer diagnosis.
You may receive local anesthetics to numb the area of the biopsy. Some surgical biopsy procedures require general anesthetics to put you in a sleep-like state. You might need to stay in the hospital after the procedure.
Although tests aren't 100% accurate all the time, receiving a wrong answer from a cancer biopsy – called a false positive or a false negative – can be especially distressing. While data are limited, an incorrect biopsy result generally is thought to occur in 1 to 2% of surgical pathology cases.
Another important factor is whether there are cancer cells at the margins, or edges, of the biopsy sample. A “positive” or “involved” margin means there are cancer cells in the margin. This means that it is likely that cancerous cells are still in the body.
All tissue that is removed is sent to a laboratory, where a pathologist will examine it under a microscope. The results will be available in about a week. If all the cancer and a margin of healthy tissue are removed during the biopsy, this may be the only treatment you need.
Biopsies involving an incision and stitches have longer recovery times, typically around two weeks. The recovery time for a non-invasive biopsy is around 24 hours. Your doctor can discuss your expected recovery time in greater detail.
Your doctor may ask you not to do certain activities for a while based on where you had the biopsy and whether it was open or closed. Unless your doctor tells you otherwise, you can do your normal activities when you feel ready. Be active. Walking is a good choice.
You won't be able to return to work or drive immediately if your needle biopsy is done during IV sedation or general anesthesia. Depending on your duties, you may be able to return to work in 24 hours.
A surgical biopsy is a procedure that involves the surgical removal of tissue from a lump or mass for examination under a microscope.
Although biopsies are often ordered when there is suspicion of cancer, results often come back negative (you don't have cancer). Your healthcare provider may have ordered a biopsy because of health concern that's entirely unrelated to cancer. A biopsy is much like any other test.
Most women who have breast biopsies DO NOT have breast cancer. In fact, about 4 out of 5 breast biopsies are benign (not cancer).
Do not take aspirin or aspirin products 7 days before the biopsy. Do not take blood thinning products 7 days before the biopsy. Do not take anti-inflammatory products 7 days before the biopsy. Do not take Vitamin E products 7 days before the biopsy.
A small amount of anesthetic numbs the skin, allowing the procedure to be almost painless. At most a biopsy feels like a slight pinch as the anesthetic is being injected. You shouldn't feel any sensation as the tissue is removed.
The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle.
Can you diagnose without a biopsy? The short answer is no. While imaging and blood draws can show suspicious areas or levels, removing tissue and studying it is the only way to diagnose cancer 100%.
There is an extremely low chance that a biopsy will cause cancer to spread. Some tumours can't be safely biopsied without spreading cancer cells. This is sometimes referred to as seeding of tumour cells. In these cases, doctors avoid core biopsy.
If your pathologist suspects certain types of cancer, such as lymphoma, he or she might need to perform additional testing to determine the subtype. This process takes an additional 24 to 96 hours, depending on the complexity of the cancer. It can be agonizing to wait for biopsy results.
