Now, type 2 endometrial carcinoma is more rare, and it has a number of subtypes.

II型宫内膜癌比较少见，有许多亚型。

Surgery is the treatment for all types and stages of endometrial carcinoma.

手术可用于治疗所有类型所有阶段的宫内膜癌。

The good news is that there are actually factors that protect against Type 1 endometrial carcinoma!

好消息是实际上有一些因素可以预防I型宫内膜癌。

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

宫内膜癌宫内膜体上皮常生长，主要有两种类型。

Even though there are two distinct types of endometrial carcinomas, we use the same stages to describe their development.

All right, as a quick recap, endometrial carcinoma is a very common cancer of the lining of the uterus.

好！快速回顾一下：宫内膜癌是一种很常见的癌症。

So having high levels of estrogen will cause the endometrium undergoes hyperplasia, leading to increased risk of developing type 1 endometrial carcinoma.

因此，高水平的雌激素会导致宫内膜增生，从而增加I型宫内膜癌的风险。

Most Type 1 endometrial carcinomas are diagnosed in stage 1 and aren't very aggressive, and because of that they have a good prognosis.

大多数I型宫内膜癌在I期就被诊断出来，不具备很强的侵袭性，因此预后良好。

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型宫内膜癌，又称为宫内膜样癌，因肿瘤的生长方式与正常的内膜体相似而得名。

Finally, a hereditary condition called Hereditary nonpolyposis colorectal cancer, also called Lynch syndrome, causes a high risk of developing certain cancers, including colon cancer and endometrial carcinoma.

最后还存在一种遗传病，称为遗传性非息肉病性结直肠癌，又称Lynch综合征，会导致增加罹患某些癌症的风险，包括结肠癌、宫内膜癌等。

Age is also a factor since endometrial carcinoma tends to develop in women who have gone through menopause, usually around 55 to 65 years of age.

年龄也是一个因素，因为宫内膜癌往往发生于绝经期的妇女，通常在55岁到65岁之间。
