Will bladder cancer cause leg swelling?

The main reason why bladder cancer causes leg swelling is that in the late stage of bladder cancer, it will widely infiltrate the pelvic cavity, lymph nodes or metastasize to other parts, which will cause pain in the lower back, ureteral obstruction, and lower limb venous return obstruction. According to your description, the patient has late-stage bladder cancer, and the tumor causes a large amount of nutritional consumption in the patient's body, resulting in hypoproteinemia and lower limb edema. In addition, the invasion of the tumor causes blood return obstruction, which can also cause lower limb edema. It is recommended to go to a regular hospital for a comprehensive examination and symptomatic treatment. If bladder cancer metastasizes to the abdominal lymph nodes, the metastatic lymph nodes may compress the inferior vena cava or the large veins in the pelvis, causing lower limb venous return obstruction and leg swelling.

Can CT scan detect bladder cancer?

If only CT examination is done, it is impossible to confirm whether there is bladder cancer. In order to better diagnose bladder cancer, it is best to do cystoscopy, which is a more intuitive examination method. Contrast examination can also be done, as well as pelvic CT or abdominal B-ultrasound to check whether there is a mass. Intermittent painless macroscopic hematuria or microscopic hematuria. For small tumors, CT examination cannot determine 100% whether it is a malignant tumor or a benign tumor.

What is the difference between CT and ultrasound for bladder cancer?

In the diagnosis of bladder cancer, there must be a clear pathological diagnosis basis. The above are various examination methods. There is no comparison between the two.

If there is a foreign body in the bladder, it can definitely be seen by bladder color Doppler ultrasound or CT. It is impossible that both examinations cannot see it. Bladder cancer is a common malignant tumor of the urinary system.
