blood in blood
Blood in the blood (called hematuria) is often the first sign of bladder cancer. Blood can turn blood orange, pink, or often bright red. Sometimes the color of the urine is normal, but a small amount of blood is detected during a blood test for other symptoms or as part of the medical examination.
Bleeding may occur one day but not the next, and bleeding may remain evident for weeks or months. But with bladder cancer, the bleeding will return at some point.
Bladder cancer often causes early bleeding (little and only if it is in the bladder) but there is very little pain or other symptoms.
Blood in the urine does not cause bladder cancer. It is usually caused by an infection, a benign (non-cancerous) tumor, kidney or bladder deposits, or another malignancy of the kidney. However, it is important to consult a doctor to determine the cause.
Changes in bladder habits or nervous symptoms
Bladder cancer can sometimes cause changes in the blood, for example:
Needing to urinate more often than usual
Pain and burning when urinating
Even if your bladder isn’t full, it feels like you need to keep going
Urinary problem or bladder weakness
Waking up to urinate frequently at night
These symptoms can be caused by a urinary tract infection (UTI), bladder stones, an overactive bladder, or an enlarged prostate (in men). However, if necessary, consult a doctor to determine the cause and treatment.
Symptoms of advanced bladder cancer
Bladder cancer that has grown or spread to other parts of the body can sometimes cause additional symptoms.
inability to bleed
Back pain on one side
Loss of appetite and weight loss
Feeling tired or exhausted
swelling of the legs
bone pain
Again, many of these symptoms are caused by something other than bladder cancer, but they are important to look out for.
