And that’s why we’re here. To explore what these changes in your pee could mean and when it may be time to see your doctor, so you have the information you need, and you can feel more reassured.
Why Urine Changes Matter in Bladder Cancer
Let’s start with the basics. The organ that holds your pee. The bladder is a balloon-shaped organ in your lower abdomen that stores urine until it’s ready to leave your body.1
When cancer develops in the bladder, it causes cells to grow in unusual ways, which can lead to changes in how your pee looks or how often you need to go to the bathroom.2
Paying attention to early signs, like blood in your urine, could make a big difference.3 Mentioning symptoms like this or changes in bladder habits could help doctors find bladder cancer earlier, when treatment may work better.3,4
It is essential to do regular screenings for your overall health and well-being. For more in-depth reading, we’ve put together some reasons why bladder cancer screening matters.
Blood in the Urine (Hematuria)
Blood in your pee is often the first and most common sign of bladder cancer.1,4 It might look pink, bright red, or even appear dark.2,4
Sometimes the blood isn't visible at all and only shows up on a urine test.3 It's easy to overlook, because it can be painless and occasional.5 That's why, if you notice blood in your pee, it's important to let your doctor know for clarity and peace of mind.3
