^† DBGPF = DBGP frequency.
^‡ Among these 219 breast cancer, 11 were DCIS; one case was a supplementary radical operation.
^§ Among these 219 breast cancers, one case supplementary radical operation was excluded from statistics of cancer size because of primary breast cancers had been removed.
^|| Among these 1,698 breast cancers, 112 were DCIS, 10 cases were supplementary radical operations and two cases were occult breast cancers.
^¶ Among these 1,698 breast cancers, two cases of axillary lymph nodes biopsies were excluded from the statistics regarding cancer size because the presence of occult breast cancer; 10 cases of supplemental radical operations were excluded from the statistics regarding cancer size as the primary breast cancers had already been removed.
