Conclusion
-
1.
The detailed study of comparative morphology of mammary glands of four different strains C3H, A,dba and C57—from the ages of21/2 to 8 months shows that certain minor differences as regards the number of side branches, acinar clusters and dilatation of ducts are seen as early as21/2 to 3 months.
-
2.
The significant developmental differences leading to abnormal growth at a later age are exhibited at the age of 51/2 to 6 months between the strains C3H, A and C57 whiledba forms a class by itself. The structural peculiarities of different strains are seen at definitely advanced stage at a later age of 6 to 8 months.
-
3.
An attempt has been made to discuss the bearing of morphological differences on strain susceptibility to cancer.
