These hormones stimulate the alveolar cells to divide and increase in number, which makes the lobule enlarge.

些素泡细胞分裂增殖，使小叶增大。

Over time, in-situ carcinoma can invade the basement membrane to become invasive carcinoma involving the ducts and lobules.

随着时间推移，原位癌可以突破基底膜并变为侵犯导管和小叶的浸润癌。

Finally, there's a finding called the " crazy paving" pattern due to swelling of the interstitial space along the walls of the lung lobules.

最终，由于肺小叶壁间质的肿胀，CT呈现“碎石路征”。

Alright, as a quick recap… breast cancer, or breast carcinoma is the uncontrolled growth of epithelial cells lining the ducts and lobules of breast.

好！快速顾一下：乳癌是指乳导管和小叶内的上皮细胞失控生长。

Cartilage from the tragus, perichondrium from the tragus or concha, and fat from the lobule are frequently used for reconstructive surgery of the middle ear.

耳屏的软骨、耳屏或耳甲的软骨膜和小叶的脂肪经常用于中耳重建手术。

This double delivery fills the liver with nutrients, that it then sorts, processes and stores with the help of thousands of tiny internal processing plants, known as lobules.

传输使肝脏充满营养，然后在数以千计，被称为小叶的内部加工工厂的帮助下，肝脏将会将营养分类、加工和储存。

The second type is called lobular carcinoma in-situ, or LCIS, and that's where clusters of tumor cells grow within the lobules, without invading the ducts, causing the affected alveoli to enlarge.

第二原位癌叫做小叶原位癌（LCIS），指肿瘤细胞局限于小叶内，并不侵犯导管，导致受累泡变大。

Once a cancer-causing mutation does occur, the affected cell, which is most commonly an epithelial cell that lines the ducts or the lobules, begins to grow and replicate out of control, forming a tumor.

一旦致癌突变发生，受损的细胞，通常是导管或小叶内的上皮细胞会开始失控地增长复制，形成肿瘤。

Breast cancer usually begins as an in-situ carcinoma, which can either be ductal carcinoma in-situ, or DCIS, which is localized to the ducts, or lobular carcinoma in-situ, or LCIS, which is localized within the lobules.

乳癌起初通常为原位癌，可以是导管内原位癌（DCIS）局限于导管内，或小叶原位癌（LCIS）局限于小叶。
