SLC in parenchymal hyperplastic areas was more than that in parenchymal hypoplastic areas and in fibroadenoma (P. 05).

②在实质增生区SLC密度多于纤维腺瘤及实质减少区（P.05）；

Phyllodes tumor shows a wide spectrum of morphology. There are no clearly distinct boundaries between PT and fibroadenoma.

叶状肿瘤形态谱系宽泛，与纤维腺瘤之间没有明确的界限。

A solid-appearing mass most likely is a noncancerous lesion, such as a fibroadenoma, but solid lesions could also be breast cancer.

如果有实性肿块很有可能是良性病变，比如纤维腺瘤，但是实性病变也有可能是乳腺癌。
