The transitional zone undergoes hyperplasia, or an increase in the number of cells, in a large percentage of older men, and that often leads to compression of the urethra.

在大多数老年男性身上，移行带通常会增生，即细胞数量的增加，常常会使尿道受压。

These typically arise from other cell types in the prostate, for example, transitional cell carcinoma arises from cells in the transitional zone, and small cell prostate cancer arises from neuroendocrine cells.

它们一般起源于其他类型的前列腺细胞，例如移行细胞癌起源于移行带，前列腺小细胞癌起源于神经内分泌细胞。
