Painless hematuria must be cancer?

Cancer generally refers to cancer. Painless hematuria may be cancer or other causes.

Cancer refers to malignant tumors. If tumor cells proliferate in the urinary system, they may destroy surrounding blood vessels and cause bleeding. After blood and urine are mixed, they are discharged together as painless hematuria. However, this symptom may also be caused by glomerulonephritis, hemophilia, etc. Therefore, patients cannot judge whether it is cancer by a single clinical manifestation. It is recommended to improve relevant examinations to clarify the specific cause and to carry out corresponding treatment for the cause.
