If I have blood in my urine, does it mean I have bladder cancer?

Having blood in the urine could indicate multiple conditions, some more severe than others, including bladder cancer.

When you notice blood in your urine, medically known as hematuria, it does not necessarily mean you developed bladder cancer.

There are numerous conditions and situations which can cause this symptom, such as a urinary tract infection, irritation or swelling in your kidneys, prostate or another part of your urinary tract, sickle cell disease, having a virus, kidney infection, bladder or kidney stones, enlarged prostate, prostate cancer, cystic kidney disease, strenuous exercise, kidney injury or taking certain medication like penicillin, aspirin or cyclophosphamide.

However, blood in your urine can also indicate bladder cancer. It appears in 40% to 50% of cases. In addition to this symptom, a lump in your side or abdomen, unexplained weight loss, a persisting pain in your side, loss of appetite, swelling in your legs and ankles, fever and fatigue are the other signs of bladder cancer.
