肺癌腫瘤擴散路徑及分期疑慮-腫瘤科

肺癌腫瘤擴散是怎麼進展？

醫生你好請問肺癌腫瘤它的擴散是怎麼進展會先從肺的淋巴開始擴散然後往後進展到氣管、大血管、心臟、腦、骨頭嗎?6月照CT有一顆2.2公分毛玻璃結節(半年前CT無此顆)如果是惡性是否分期比較不太會是2~3~4期嗎?想知道CT上面看淋巴沒腫大+肺部周邊沒其它狀況 ，這樣會有可能說已經轉移到其他器官了嗎?因為還沒開刀所以很擔心會是中後期的.....後續還會回診但目前很擔心想問問醫生解惑以下是報告影像內容Imaging findings :THE MDCT OF THE CHEST WAS PERFORMED WITHOUT IV CONTRAST MEDIUM ENHANCEMENT;AND REVEALED THAT: Findings: The lung parenchyma is well demonstrated with some ground-glass opacities in both lungs.The bilateral mainstem bronchi are identified with normal distribution and appearance.The mediastinum shows clear appearance without evidence of abnormal mass lesion or enlarged lymph nodes.The pleural spaces show no evidence of fluid collection or abnormal lesion.
