微侵襲性腺癌是否等同於一期癌症？病理報告分析-胸腔內科

有關肺腺癌病理報告的疑問？

醫師您好:經低劑量肺癌篩檢出肺腺癌,月初以胸腔鏡移除腫瘤, 醫生告訴我是原位癌, 可是我從病理報告上看到的是微浸潤腺癌, 經我上網搜尋資料都呈現出只要是微浸潤腺癌就屬一期癌症, 這讓我很困惑, 想尋求第二個醫生的見解, 以下是病理報告, 麻煩醫生能幫我解答, 謝謝Pathological Diagnosis:(select all that apply and add as needed) Lung, right midddle lobe, wedge resection-----S/P frozen section, minimal invasive adenocarcinoma.
