Bladder cancer starts in the lining of the bladder and often speaks up early through changes in urine. Blood is its favorite warning flag.
Painless blood in the urine is the classic first sign. The color may be bright red, pink, or cola-brown, and it can come and go, so people often blame vitamins or dehydration.
Urge and frequency follow. You dash to the bathroom every hour, but only small amounts come out, and the urge returns quickly.
Burning may join the mix. It feels like a urinary tract infection, yet no fever or bacteria show up.
Night trips increase. You wake more often than you used to, even when you stop drinking fluids early.
Later, urine flow can slow or stop if the tumor blocks the outlet, and flank pain may appear if the kidneys swell.
Weight loss, fatigue, and bone pain can show up if the cancer spreads, but these are late clues.
