The cancer prognosis of gland of papilla is better.
Tubular gland cancer: Account for 67.22%, cancer tissue presents tube structure, according to the intensity of splitting up, assign for being tertiary, differentiate gland cancer high, the cancer tissue is in charge of forming by the gland not of uniform size, the cancer cell splits up better, take the form of the column or high column, arrange it neatly. China differentiates gland cancer, difference of splitting up of the cancer cell, the size is not very unanimous and presenting and replying layer false, the nucleus is big, can not arrange neatly, the top of thick liquid of often direct afterbirth. It is low to differentiate gland cancer, the irregular gland of rarely seen small quantity is in charge of a kind of structure in cancer is organized, difference of splitting up of the cancer cell, much shape, come in different sizes. The core is big, there is little thick liquid of afterbirth, find nuclear fission easily. Can form irregular the intersection of cell and pieces of Suo and cancer nest.
Mucus gland cancer: It is the characteristic that this kind of cancerous swelling presents a large number of mucus while organizing. Mucus composition account for all more than 60% that cancer organize, can diagnose as mucus gland cancer.

Afterbirth size, shape, dyeing more even and unanimously, typical kinds of cancer cells are shown in multilateral, the thick liquid of afterbirth is medium-sized, the core is round, can not dye deeply, the ribbon of common nest bulk, many kinds of structure that the gland is vesicular,etc..
