Dad had bladder cancer biopsy.waiting pathology report. dr said fairly large tumor and a few satellite tumors. Is this bad news?

Do they extend beyond the bladder to lymph nodes or more distant sites? How immature are the tumor cells? The pathology report and CT and/or MRI studies will tell us. Then, the treatment and the long term outlook can be stated. ...Read more

I am female, and had a bladder polyp (papimillary carcinoma) taken out 2 years ago. I am going for 2nd cystoscopy, is it a polyp tumor or cancer?

I am female, and had a bladder polyp (papimillary carcinoma) taken out 2 years ago.  I am going for 2nd cystoscopy, is it a polyp tumor or cancer?

Can bladder cancer be seen on ultrasound? If u/s shows no tumor, should further testing be done on a child with gross terminal hematuria? Not a uti.

Can bladder cancer be seen on ultrasound? If u/s shows no tumor, should further testing be done on a child with gross terminal hematuria? Not a uti.

Here are some ...: Ultrasound study only gives a gross rough imaging assessment with low sensitivity for small lesions. So, it is an absolute saying no bladder cancer. Terminal gross hematuria suggests its origin from the urethra, especially prostate urethra. So, a cystourethroscopy under anesthesia is needed. But, how far an evaluation should go for? It should be individualized. So, ask and talk with Doc timely. ...Read more

I had bladder cancer 15 years ago. I had a trace of blood inmy urine. The doctor scoped me and found no tumor. He sent my blood to get a full report. What else could be the cause of blood in urine?

Lots of things: Congratulations on your cancer survival. With blood in the urine it's certainly possible that the tumor had returned but the scope is reassuring so that's clearly positive. Could be infection causing the blood, could potentially still be treatment related though typically that would have happened earlier. Good luck. ...Read more

Bladder (Definition)

The bladder is a muscular organ in the pelvis that accepts urine from the kidneys, stores the urine at low pressure, & expels the urine during voluntary voiding. Though seemingly a simple reservoir, the bladder is a complex organ intricately connected with the brain and spinal cord with sensory, motor, and autonomic circuits. The muscular layer that contracts during voids ...Read more
