3-5 Grade 1 tumor (well-differentiated). Best prognosis. 6-7 Grade 2 tumor (moderately differentiated). Medium prognosis. 8-9 Grade 3 tumor (poorly differentiated). Worst prognosis. Lower-grade tumors, with a more favorable prognosis, can be treated less aggressively, and have a better survival rate.
Invasive carcinoma NST is one of the most common types of all breast cancers, accounting for 55% of breast cancer incidence. [2] Of the invasive breast cancers, invasive carcinoma NST accounts for up to 75% of cases. [3] [4] It is also the most common form of breast cancer occurring in men, accounting for 85% of cases.

Thus invasive ductal carcinoma, the most common form of breast cancer, is adenocarcinoma but does not use the term in its name—however, esophageal adenocarcinoma does to distinguish it from the other common type of esophageal cancer, esophageal squamous cell carcinoma. Several of the most common forms of cancer are adenocarcinomas, and the ...
It shows the typical features of tubules lined by a single layer of cuboidal to columnar epithelial cells with small to intermediate sized nuclei low grade nuclei and sparse mitoses (grade 1). [1] Tubular carcinoma is a subtype of invasive ductal carcinoma of the breast. [2] [3] More rarely, tubular carcinomas may arise in the pancreas [4] or ...
Of the many cancer-specific schemes, the Gleason system, [3] named after Donald Floyd Gleason, used to grade the adenocarcinoma cells in prostate cancer is the most famous. This system uses a grading score ranging from 2 to 10. Lower Gleason scores describe well-differentiated less aggressive tumors.

Intratumoral morphological heterogeneity in invasive breast carcinoma. Diversity of invasive growth of breast cancer is shown, which can be classified into five main morphological structures: alveolar, trabecular, tubular, solid structures, and discrete groups of tumor cells.
