肺癌的生长速度差别很大,与癌的组织类型有很大关系。一般认为,肺内肿块在30天以内体积增大一倍者肺癌的可能性很小,通常为良性。但最近我院见到一例肺内孤立性肿块,在短期内迅速增大,其体积倍增时间仅为4.2天,后经手术切除及病理检查证实为肺腺癌。肺癌体积倍增时间这样短,生长如此迅 The growth rate of lung cancer varies greatly, and it has a great relationship with the type of cancer. It is generally believed that lung tumors are less likely to have lung cancer within a 30-day increase in volume within 30 days and are usually benign. Recently, however, we have seen a case of solitary lump in the lung, which has rapidly increased in the short term. The volume doubling time was only 4.2 days. After surgery and pathological examination, it was confirmed as lung adenocarcinoma. Lung cancer volume doubling time is so short, so fast growing
