If a bladder tumor has started disintegrating what are the chances it has spread?

Puzzling ? How does one determine "disintegration"? Bladder tumors can be superficial, confined to bladder transitional epithelium, and only a biopsy by way of cystospy can discern if it invades the muscle. Once invading muscle, the chance of spread to nodes and else where rises. This is why the option includes removing the bladder (cystectomy) at this stage, and chemotherapy is commonly used before and or.
