There is emerging evidence that finasteride both treats suppurative sweats in women [67] and reduces the incidence of bladder cancer [68,69]and induces type 2 diabetes [70], down-regulates androgen receptor expression in the renal cortex [71], forms blood clots [72], and alters intestinal microbial abundance [73,74] among other things. This evidence concerns the gene AR and urinary bladder cancer.
