Why would a doctor want a second biopsy?
Sometimes a biopsy sample might not be big enough to evaluate. Other times, the pathologist can see that the sample was not taken from the correct area. In these cases, the pathologist will ask your doctor to repeat the biopsy, so the pathologist can make a conclusive and accurate diagnosis.
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.
Sometimes, the result of a biopsy will be inconclusive, meaning that the test has not produced a definitive result. This can happen for several reasons: There could have been a problem processing the sample, the sample didn't contain enough of the affected tissue or the sample size was not large enough.
Contact the pathology department of the hospital where you had your biopsy and ask them to send your slides to the second pathologist. For more information on cancer and biopsies, see Should You Trust Breast Biopsy Results and our Cancer Guide.
Current guidelines recommend a repeat biopsy within 3–6 months after the initial diagnosis.
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.
Molecular or genetic tests for diagnosis
Sometimes, other tests help the doctor further classify the tumor. For example, to diagnose some types of leukemia, the pathologist looks for specific genetic changes in the cancerous blood cells.
Group. P5 - Tissue Pathology. Examination of complexity level 4 biopsy material with 1 or more tissue blocks, including specimen dissection, all tissue processing, staining, light microscopy and professional opinion or opinions - 18 or more separately identified specimens.
Biopsies are highly accurate. Pathologists use specialized microscopes to look at the cells in your sample. If you are not completely comfortable with the results, you can always get a second opinion.

Can a biopsy diagnosis be wrong?
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.
Biopsy specimens are examined by pathologists, who look at the tissue sample under a microscope in order to determine if it is cancerous. It has been estimated that 1 in every 71 biopsies is misdiagnosed as cancerous when it was not, and 1 out of every 5 cancer cases was misclassified.
Systematic reviews of the literature have indicated that the quest for a second opinion in different patient populations varied widely between 7 and 36% [20] and between 1 and 88% [22].
Getting a second opinion is a good idea when you have a medical issue. In fact, you might find that your general doctor will refer you to a specialist or encourage you to see another doctor before you even ask.
Am I not insulting my doctor if I request a second opinion? Not at all. It is standard medical practice to get another opinion. Doctors do it all the time as part of their own process of diagnosing a problem.
A biopsy is a diagnostic procedure that can help doctors diagnose diseases. It involves removing a sample of tissue or cells and sending it to a pathologist for examination, usually under a microscope. The word biopsy comes from the Greek words “bios,” meaning life, and “opsis,” meaning sight.
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. Lymph nodes. The pathologist will also note whether the cancer has spread to nearby lymph nodes or other organs.
1. Most women who have breast biopsies DO NOT have breast cancer. In fact, about 4 out of 5 breast biopsies are benign (not cancer). 2.
Conclusions: In soft tissue mass diagnosis, core biopsy is more accurate than fine-needle aspiration on all accounts, and open biopsy is more accurate than both in determining malignancy, establishing the exact diagnosis, and the guiding appropriate treatment.
Fine-needle, core-needle, and surgical biopsies are the three types of biopsies. Thankfully, when looking into what percentage of breast biopsies are cancer? The answer is low—only 20%.
What are the 3 types of biopsies?
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.
How Soon Can I Get My Biopsy Results? Based on the urgency and type of analysis, results can take up to ten days.
The test misses the cancer. This can delay diagnosis and ultimately lead to longer and more extensive treatment. Some types of biopsy procedures are more prone to false negative results than others. In general, needle biopsies have a higher risk of a false negative result than a surgical biopsy.
A high grade number (grade 3) means a faster-growing cancer that's more likely to spread.
Traditional biopsies sample tissue from 12 systematically placed points within the prostate that are blind to tumor locations. Such procedures have helped to save many lives, but are prone to missing or misclassifying prostate cancers, which has led doctors both to over and under treat their patients.

An inconclusive result is neither positive nor negative. This result can occur from inadequate sample collection, very early-stage infection, or for patients close to recovery.
If your PCR or antigen test is inconclusive or indeterminate for COVID-19, it means that a small amount of viral DNA was identified but it was not enough to test positive.
Are biopsy results always given face to face?
Many consultants prefer to see you in person even if the biopsies are good news, because there may still be important information they need to give you, and you may want to ask follow up questions. Also, it is not unusual for you to be sent an appointment BEFORE the biopsy results have come back from the path lab.
The good news is that 80% of women who have a breast biopsy do not have breast cancer. There are three types of biopsies: Fine-needle aspiration.
Misdiagnosis of Cancer Statistics
Many deaths could be prevented if the rate of misdiagnosis was not so high. It is estimated that approximately 10 to 20 percent of all cases of cancer are misdiagnosed. One study found that about 28 percent of the mistakes made out of 583 cases were life threatening or life altering.

The doctor also may order lab tests, imaging tests (scans), or other tests or procedures. You may also need a biopsy, which is often the only way to tell for sure if you have cancer. This page covers tests that are often used to help diagnose cancer. Depending on the symptoms you have, you may have other tests, too.
“Patients should seek another opinion if they feel uncomfortable with their initial team, if they have a rare cancer that another doctor may have more expertise with, or if they are confused about their diagnosis or treatment options,” she says.
Patients seeking a second opinion sought to gain more information or reassurance about their diagnosis or treatment. While many second opinions confirm the original diagnosis or treatment, discrepancies in opinions had a potential major impact on patient outcomes in up to 58% of cases.
A second opinion can help you decide which treatment is most appropriate for your particular situation. It's important to make sure that any second (or third) opinion you seek is from a physician who has broad experience and expertise treating the condition that you've been diagnosed with.
Misdiagnosis happens for many reasons, from busy doctors to patients who don't disclose their full range of symptoms. There are many steps you can take to help get the right diagnosis, like writing down a list of concerns, taking photos of your symptoms, and continuing your research when you get home from the doctor.
A surgeon or other specialist wants to know specifics to treat you without adverse reactions or allergies. As treatment progresses and your condition is diagnosed, the same questions might have different answers, or the same answers (like drug allergies) might become more important.
How often are doctors wrong about diagnosis?
Each year in the U.S., over 12 million adults who seek outpatient medical care receive a misdiagnosis, according to a recent study by BMJ Quality & Safety. That translates to about 5 percent of adults, or 1 out of 20 adult patients.
A second set of eyes, however, may identify information that was missed or misinterpreted the first time. A study that reviewed existing published research found that 10 to 62 percent of second opinions resulted in major changes to diagnoses or recommended treatments.
Medicare covers second opinions if a doctor recommends that you have surgery or a major diagnostic or therapeutic procedure. Note: Medicare does not cover second opinions for excluded services, such as cosmetic surgery.
In fact, a recent study by researchers at the Mayo Clinic found that in 66% of the cases studied, the second opinion helped better define or refine the original diagnosis and in 21% of the cases, the second opinion resulted in final diagnoses that were significantly different than the original diagnoses.
Biopsies are most often done to either confirm or rule out a suspicion of cancer. However, biopsies are also performed to diagnosis other causes of your symptoms including: Inflammatory disorders, such as in the kidney (nephritis) or the liver (hepatitis). Infections, such as tuberculosis.
A false negative result reports inaccurately that a condition is absent. These are usually due to sampling errors or missing the lesion with the biopsy. A false negative result will require a second biopsy.
Generally, after a patient receives positive melanoma results, his or her doctors will need to proceed with staging the malignancy— which essentially means determining the extent of the cancer—and developing a treatment plan based on how far the cancer has progressed.
A doctor should recommend a biopsy when an initial test suggests an area of tissue in the body isn't normal. Doctors may call an area of abnormal tissue a lesion, a tumor, or a mass.
Analysis of all patients regarding the accuracy of biopsy techniques revealed a 96% accuracy for diagnosing malignancy via CNB and 100% for incisional biopsy.
After the tissue sample is taken, it will be examined under a microscope to help identify the nature of the problem. This often means that a definite diagnosis can be made.
What does high risk in a biopsy mean?
High-risk benign breast abnormalities are conditions that may increase your risk for developing cancer in the future. If you have a high-risk benign tumor or lesion, your physician may recommend surgical removal.
