Endometrial carcinoma involves the abnormal growth of the epithelial cells that make up endometrial glands, and there are two main types.

子宫内膜癌涉及子宫内膜腺体上皮细胞异常生长，主要有两种类型。

It's followed by the proliferative phase, during which the rising levels of ovarian estrogen make the functional layer of the endometrium thicken and sprout endometrial glands.

之后是增殖期，伴随卵巢分泌雌激素的上升，子宫内膜功能层增厚，子宫内膜腺体生长。

The most common is Type 1 endometrial carcinoma, which is also called endometrioid carcinoma because the tumours grow in a way that looks like normal endometrial glands.

最常见的是I型子宫内膜癌，又称为子宫内膜样腺癌，因肿瘤的生长方式与正常的内膜腺体相似而得名。
