Atumor that is highly differentiated and cells very similar to normal parent cells fall into grade per broder's index.

A tumor that is highly differentiated and cells very similar to normal parent cells fall into grade 1 per broder's index.

Tumors are graded as 1, 2, 3, or 4, depending on the amount of abnormality. In Grade 1 tumors, the tumor cells and the organization of the tumor tissue appear close to normal. These tumors tend to grow and spread slowly. In contrast, the cells and tissue of Grade 3 and Grade 4 tumors do not look like normal cells and tissue. Grade 3 and Grade 4 tumors tend to grow rapidly and spread faster than tumors with a lower grade.

it may have problems procreating.
