By allowing tumours to advance to palpable proportions prior to initiating treatment, we have potentially allowed them to outgrow their vasculature and so undergo spontaneous necrosis and apoptosis.
The proportion palpable on both breasts was smaller in older children, however (trend p < 0.0001 and 0.0005 in boys and girls, respectively).
The prevalent round of the Canadian trial had a very high proportion of palpable cancers (partly skewed by the nature of their recruitment strategy).
Prevalence of palpable tape or erosion: the proportion of patients with palpable tape or erosion will be compared between groups using a chi-square test.
Screening and improvement in diagnostic techniques should lead to a shift in stage distribution towards earlier stages, whereas in our population, this did not change significantly, and the proportion of clinically palpable tumours remained constant.
The proportion of children with palpable buds was smaller in older children (trend p < 0.0001 and 0.0003 for boys and girls, respectively); at 1 month or after, only 5 of 20 girls (25%) and 1 of 20 boys (5%) had a palpable breast bud.
Although mammary intra-epithelial neoplasias (MINs) are considered precursors of adenocarcinomas, these were a small proportion of tissues because only palpable lesions were collected.
One of the earliest methods used for estimation of the amount of malaria in a given locality is that of determining the proportion of person with a palpable enlargement of the spleen.
Finally, no associations were found between tissue abnormalities (MRI and CR) and physical examination findings (except for crepitus), which might, at least partly, be explained by the low proportion of persons with bony enlargement (11%) or palpable warmth (4%) in our cohort.
Lobular carcinomas may also be difficult to detect clinically because they less commonly form a palpable mass [ 52], which may in part explain the similar proportion of lobular carcinomas in both groups.
