Abstract
Two-hundred and ninety cases of primary breast cancer have been treated at the department during 12 years and 5 months from August 1978. Of the 290 cases 16 of T0 and 77 of T1 were studied for the diagnostic methods by dividing into biopsy group and non-biopsy group.
In 68 cases of T1 invasive carcinoma which were subtracted 9 noninvasive carcinoma cases from 77, biopsy ratio was 76% and 16 cases (24%) were diagnosed without biopsy. These 16 non-biopsy cases predominantly included elders over 70 years old, and fatty women whose hight-weight ratio of +11% or more, and 75% of them had tumors with diameter of 16 mm or more.
The palpation of irregularity of the tumor surface, skin retraction and inferiority of tumor movement were important in clinical diagnosis. In echography, irregularity of the tumor surface, internal strong, coarse, and heterogenous echoes were the findings suggestive of maligancy. In mammography, tumor shadow, spicular and microcalcification were the findings suggesting malignancy.
Biopsy surely plays an important role in the diagnosis of early breast cancer, but, it is also important that the above findings in palpation, echography and mammography should be examined in detail at first.
