What if the biopsy is positive?

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. Lymph nodes.

Why would a biopsy be inconclusive?

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.

Why do biopsies take so long?

After the first sections of tissue are seen under the microscope, the pathologist might want to look at more sections for an accurate diagnosis. In these cases, extra pieces of tissue might need processing. Or the lab may need to make more slices of the tissue that has already been embedded in wax blocks.

Can a biopsy be wrong?

While biopsies provide important information that helps diagnose cancer and other diseases, several studies have found that there can be errors in the interpretation of the results. Seeking a medical second opinion can make a difference in both your diagnosis and your treatment options.

Are pathology reports always accurate?

Most people believe that pathology reports are always correct, accurate and that what the report says is carved in stone. This is not true. Pathology reports are subjective. They are not objective.

A biopsy also helps your doctor determine how aggressive your cancer is — the cancer’s grade.

How many biopsies are taken during a colposcopy?

Are biopsies 100 accurate?

Of the adequate specimens, the accuracy of core/open/fine needle biopsy was 96%, 97% and 94% for determining malignant versus benign; of the correctly identified malignant lesions 97%, 100% and 80% were accurate for histological grade; and 79%, 84%, 59% for histological subtype.

Can a pathology report be wrong?

Previous studies have shown that serious errors in pathologic diagnosis occur at rates that vary depending on the type of tissue under examination. For tissues of the female reproductive tract, this error rate is roughly 5%. Within this field of gynecologic pathology, there are particular “hotspots” of misdiagnosis.

Why would a pathologist get a second opinion?

A second opinion should be obtained by a physician for a challenging case in an attempt to arrive at an accurate diagnosis leading to optimal treatment. And second opinions should be requested by patients when diagnoses require life-altering therapy, to ensure accurate diagnoses and proper treatment plans.
