A female asked:

If a biopsied 1.7 x 1.2 x 1.0 cm isoechoic nodule (nonspecific) turns out cancerous, wouldn't the biopsy itself break the enclosure and spread cancer?

No: Biopsies are performed by either fine needle aspiration FNA) or core biopsy. Both techniques are specifically designed to prevent any contamination along the track of the needle. FNA uses suction to pull tissue into a syringe. Core biopsy uses a shield that is pushed down over the needle before it is withdrawn. There have never been any instances of these techniques causing spread of the tumor
