Types of prostate cancer, including follicular adenocarcinoma, squamous carcinoma, small cell carcinoma and so on. 1. Vesicular adenocarcinoma: it is the most common type of prostate cancer, about 95% or more, originating from glandular epithelial cells. Cancer cells form glands or adenoid structures of different sizes, shapes and irregular arrangement, irregularly arranged in multiple layers, with different sizes of nuclei and frequent schizonts. 2. Squamous carcinoma: in well-differentiated squamous cell carcinoma, stratified keratinized material, i.e. keratinized beads, can be seen in the center of the cancer nests, and intercellular bridges can be seen between cells. 3. Small cell carcinoma: among prostate cancers, the incidence of this type is lower. The cancer cells are small, small-cell, undifferentiated, relatively malignant, invasive and metastatic. If you are suffering from prostate cancer, it is recommended to go to regular hospitals for consultation and examination and early treatment to avoid delaying your condition.
