CNB should be performed if:
- your physician has recommended it
- you have a suspicion of cancer
- you have been diagnosed with a lesion of unclear origin
The core needle biopsy (CNB) involves taking cell samples from an existing nodule (breast nodule or nodule from other anatomical structures) for microscopic evaluation. This type of biopsy allows the collection of larger tissue amounts compared to fine-needle biopsy.
However, CNB needs to be repeated several times to obtain an adequate amount of material for examination.
