What does atypical cells mean in thyroid biopsy?

ACUS is an abbreviation for “atypical cells of undetermined significance”. This occurs when the thyroid FNA findings don’t show for sure if the nodule is either benign or malignant. The pathologist looks at the cells and just can’t be sure if it is cancer, or non-cancer (benign).

Is fine-needle aspiration biopsy accurate and reliable in diagnosing cancer?

Results: FNAB was diagnostic in 93% of patients and was 95% accurate. There were 5 false-negative results and no false-positive results for the diagnosis of malignancy. The overall sensitivity of FNAB was 93%, and the specificity was 100%.

Can a fine needle biopsy detect cancer?

During a fine needle aspiration (FNA), a small amount of breast tissue or fluid is removed from a suspicious area with a thin, hollow needle and checked for cancer cells. This type of biopsy is sometimes an option if other tests show you might have breast cancer (although a core needle biopsy is often preferred).

Can fine needle aspiration spread cancer?

They found no difference in cancer recurrence between 208 patients who had ultrasound-guided fine needle aspiration (EUS-FNA) and the 48 patients who did not have a biopsy. In the current study, they examined 11 years (1998–2009) of Medicare data on patients with non-metastatic pancreatic cancer who underwent surgery.

How serious is atypical ductal hyperplasia?

Atypical hyperplasia isn’t cancer, but it increases the risk of breast cancer. Over the course of your lifetime, if the atypical hyperplasia cells accumulate in the milk ducts or lobules and become more abnormal, this can transition into noninvasive breast cancer (carcinoma in situ) or invasive breast cancer.

Can a thyroid biopsy spread cancer?

Abstract. Implantation of cancer cells from needle biopsy has been reported in a wide range of malignancies. Fine needle aspiration biopsy has become an accepted method for assessment of thyroid nodules. Local reappearance of thyroid cancer from needle track dissemination is a rare complication of thyroid aspiration.
