Breast cancer is one of the more common cancers occurring, determining life threatening and depression in affected females.

[Expression of epithelial oncoproteins in large intestine neoplasms].

The high incidence of the colorectal cancer in the industrialized countries has drawn the interest of the scientific community to detect and investigate its morphologic precursors. Growth factors and oncoproteins could be useful to investigate the morphologic and biologic evolution of precancerous lesions of the large bowel. Therefore the Authors report the results obtained from 30 selected patients with hyperplastic and adenomatous polyps, and different histotypes of colorectal cancer, investigated using the EGF-r and p62 protein expression.
