The removed cells are examined under a microscope and further tested to check for the presence of breast cancer. A biopsy is the only diagnostic procedure that can definitely determine if the suspicious area is cancerous. The good news is that 80% of women who have a breast biopsy do not have breast cancer.
In fact, about 4 out of 5 breast biopsies are benign (not cancer).
Over one million people have breast biopsies each year in the United States. Approximately 20% of the biopsies reveal a breast cancer diagnosis.
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.
Fortunately, most breast biopsies come back as "benign". This means that the biopsied area shows no signs of cancer or anything dangerous. When a biopsy comes back with one of these benign diagnoses, no treatment is usually necessary, and we usually recommend returning to routine yearly screening for women over age 40.

Biopsies carry a small risk of bleeding and infection. In recent studies, scientists have worked to quantify the risks and benefits of biopsies in an effort to better inform patients and fellow physicians.
Your GP, hospital consultant or practice nurse will give you your results and explain what they mean. A biopsy is sometimes inconclusive, which means it hasn't produced a definitive result. In this case, the biopsy may need to be repeated, or other tests may be required to confirm your diagnosis.
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.
In most cases, doctors need to do a biopsy to be certain that you have cancer. A biopsy is a procedure in which the doctor removes a sample of abnormal tissue. A pathologist looks at the tissue under a microscope and runs other tests on the cells in the sample.
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.
Breast abnormalities can also be found through self-examination or when symptoms arise. Suspicious mammographic findings may require a biopsy for diagnosis. More than 1 million women have breast biopsies each year in the United States. About 20 percent of these biopsies yield a diagnosis of breast cancer.
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%.
Currently, 6 to 8 biopsies are recommended for diagnosis of a suspected malignant lesion. However, multiple biopsies may result in several problems, such as an increased risk of bleeding, procedure prolongation, and increased workload to pathologists.
Is there ever a time when a patient should ask their doctor for a biopsy (or for a specific type)? A biopsy is only recommended if there's a suspicious finding on a mammogram, ultrasound or MRI, or a concerning clinical finding. If a scan is normal and there are no worrisome symptoms, there's no need for a biopsy.
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.
Complications from a biopsy
Excessive bleeding (haemorrhage) Infection. Puncture damage to nearby tissue or organs.
“Suspicious” thyroid biopsy: this happens usually when the diagnosis is a follicular or hurtle cell caused lesion. Follicular and hurtle cells are normal cells found in the thyroid. Current analysis of thyroid biopsy results cannot differentiate between follicular or hurtle cell cancer from noncancerous adenomas.
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.
The biopsy results help your health care provider determine whether the cells are cancerous. If the cells are cancerous, the results can tell your care provider where the cancer originated — the type of cancer. A biopsy also helps your care provider determine how aggressive your cancer is — the cancer's grade.
