浸潤性癌（Invasive camcer）實(shí)際上指病理學(xué)上的一個概念，主要與原位癌相對比。浸潤性癌一般是指癌細(xì)胞穿透了基底膜向深層浸潤的一種癌癥。在浸潤性癌中，癌細(xì)胞可以通過淋巴管或血管向周圍組織擴(kuò)散，進(jìn)而發(fā)生淋巴結(jié)轉(zhuǎn)移或者遠(yuǎn)處器官轉(zhuǎn)移。這種擴(kuò)散可能是癌癥的一個惡性特征，因?yàn)槠湓黾恿税┘?xì)胞在身體內(nèi)擴(kuò)散和形成遠(yuǎn)處轉(zhuǎn)移的風(fēng)險。治療浸潤性癌通常需要更加積極的干預(yù)，例如外科手術(shù)、放射治療、化療等，需要在醫(yī)生的指導(dǎo)下進(jìn)行，以控制癌細(xì)胞的進(jìn)一步擴(kuò)散和減少腫瘤的體積。 非浸潤性癌（Non-Invasive camcer）是指癌細(xì)胞局限于上皮層內(nèi)，還沒有突破基底膜，沒有發(fā)生浸潤和遠(yuǎn)處轉(zhuǎn)移的情況。常見的非浸潤性癌包括乳頭狀腺癌、管狀腺癌、黏液腺癌、大汗腺癌、鱗狀細(xì)胞癌等。 Non-Invasive Vs. Invasive Breast Cancer
There are many types of breast cancer, and many ways to describe them. One way to differentiate is non-invasive vs. invasive breast cancer, which refers to whether the cancer has spread or not.
乳腺癌有很多類型，也有很多方法來描述它們。區(qū)分的一種方法是非浸潤性乳腺癌與侵入性乳腺癌，這是指癌癥是否已經(jīng)擴(kuò)散。 Non-invasive or “In situ” breast cancer (ductal carcinoma in situ or DCIS) is a cancer that starts in a milk duct and has not grown into the rest of the breast tissue. Non-invasive cancers stay within the milk ducts or lobules in the breast. They do not grow into or invade normal tissues within or beyond the breast. 非浸潤性乳腺癌即“原位”乳腺癌（導(dǎo)管原位癌/DCIS）是一種始于乳管的癌癥，尚未生長到乳腺組織的其余部分。非浸潤性癌局限在乳腺的乳導(dǎo)管或小葉內(nèi)。它們不會生長或侵入乳房內(nèi)或乳房外的正常組織。 Invasive (or infiltrating) breast cancer is any type of breast cancer that has spread (invaded) into the surrounding breast tissue.
乳腺癌是一種乳腺癌，是乳腺癌的一種常見類型。 Most breast cancers are invasive. Whether the breast cancer is invasive or non-invasive will determine your treatment choices.
大多數(shù)乳腺癌是侵襲性的。乳腺癌是侵襲性的還是非侵襲性的將決定您的治療選擇。About 90% of invasive breast cancers fall into the following types:大約90%的浸潤性乳腺癌屬于以下類型：
· Invasive ductal carcinoma (IDC). This is the most common type, making up about 80%. With IDC, cancer cells start in a milk duct, break through the walls, and invade breast tissue. It can remain localized, which means it stays near the site where the tumor started. Or cancer cells may spread anywhere in the body.·浸潤性導(dǎo)管癌（IDC）。這是最常見的類型，約占80%。在IDC中，癌細(xì)胞從乳管開始，突破壁并侵入乳腺組織。它可以保持局部性，這意味著它停留在腫瘤開始的部位附近。或者癌細(xì)胞可以擴(kuò)散到身體的任何地方。
· Invasive lobular carcinoma (ILC). This type accounts for about 10% of invasive breast cancers. ILC starts in the lobules or milk glands and then spreads. With ILC, most women feel a thickening instead of a lump in their breast.·浸潤性小葉癌（ILC）。這種類型約占浸潤性乳腺癌的10%。ILC開始于小葉或乳腺，然后擴(kuò)散。對于ILC，大多數(shù)女性感覺乳房增厚而不是腫塊。
In some cases, invasive and non-invasive breast cancer can both be seen in the same specimen. This means that part of the cancer has grown into normal tissue and part of the cancer has stayed inside the milk ducts or milk lobules. It would be treated as an invasive cancer.
在某些情況下，浸潤性和非浸潤性乳腺癌都可以在同一標(biāo)本中看到。這意味著部分癌癥已經(jīng)生長到正常組織中，部分癌癥已經(jīng)維持在乳管或乳小葉內(nèi)。它將被視為一種侵襲性癌癥。 A breast cancer also may be a “mixed tumor,” meaning that it contains a mixture of cancerous ductal cells and lobular cells. This type of cancer is also called “invasive mammary breast cancer” or “infiltrating mammary carcinoma.” It would be treated as a ductal carcinoma.
乳腺癌也可能是“混合腫瘤”，這意味著它同時含有癌性導(dǎo)管細(xì)胞和小葉細(xì)胞。這種類型的癌癥也被稱為“浸潤性乳腺癌”。它將被視為導(dǎo)管癌。
