It has been reported that some patients have been misdiagnosed with Haemorrhagic Cystitis: Non-infectious, when in fact the correct diagnosis in their specific case was Bladder Cancer.
Bladder cancer begins in the cells that line the inside of your bladder called urothelial cells. These cells exist in the kidneys and the ureters that connect your kidneys to the bladder and the cancer can occur in these locations too. Symptoms of bladder cancer include blood in the urine, frequent urination, painful urination and back pain. Bladder cancer can be misdiagnosed as urinary tract infections, cystitis (bladder infection), haemorrhagic cystitis, kidney stones, renal cell carcinoma, ureteral trauma.
