Bladder cancer can metastasize, and the main ways of metastasis are direct infiltration, lymphatic metastasis, blood metastasis and so on. Bladder cancer is mainly uroepithelial cancer, which can be caused by smoking and other reasons. The main way of metastasis of bladder cancer is lymphatic metastasis, which can be transferred to lymph nodes in the pelvic occlusion and other places through lymphatic circulation. Besides, it can also spread directly to invade nearby tissues and organs.
