(b) Histologically, observed the presence of area carcinoma invasion with hyperchromasia cells surrounding the fibrovascular stroma (#). DMBA induces breast cancer in control (c) and açaà (e) groups. (d) Area carcinoma invasion with hyperchromasia cells surrounding the fibrovascular stroma (#) and higher number of inflammatory cells (→). (f) We also observed invasive carcinoma (#), however, we noted a decrease of number of inflammatory cells (*)
