Are biopsies 100 accurate?

In regard to determining exact diagnosis, fine-needle aspiration had a 33.3% accuracy and core biopsy had a 45.6% accuracy. With regard to eventual treatment, fine-needle aspiration was 38.6% accurate and core biopsy was 49.1% accurate.

Can a radiologist tell if it is breast cancer?

A radiologist looks for masses, irregular breast tissue, and/or calcifications that have certain patterns and characteristics that may be a sign of abnormally dividing cancer cells.

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.
