Elastic tissue hyperplasia occurs normally in senile
atrophic mammary tissue. It occurs also pathologically in
mammary carcinomata, as a local reactive response Of the host's
tissues to the tumour growth.
It is suggested that a further study of these elastic
changes in relation to the site of mammary carcinoma origin and in
relation to other suspected precancerous conditions, would be of
academical and practical value to our knowledge of the pathogenesis
and pathology of mammary carcinoma.
