Thank you flyaqmt for the translation. Also, thank you xb3263 for the good and knowledgble response. In the US, breast 细针穿刺 for primary diagnosis is getting less and less, it is commonly replaced by breast 粗针穿刺。 Breast frozen sections are very rare because 粗针穿刺 most often gives definitive diagnosis and frozen of breast lesions can be very difficult and misleading. However, breast 细针穿刺 is still used for rule out or rule in recurrent breast cancer and the materials can be collected to make cell blocks to do ER, PR, and Her2 studies even FISH (we do that in our hospital).

 The basic concept of what is breast 细针穿刺 and waht size of the needle qualifies breast 细针穿刺 is still debatable? The most accepted concept is that any needle larger than 21G (内直径0.5 mm) is considered 粗针穿刺.
