Lower extremity edema
Some patients with bladder cancer may experience edema in the feet. This symptom is not common in an early stage of the disease, and it is only seen in patients who are diagnosed with an advanced stage of bladder cancer. The swollen feet look puffy and heavy, and swelling results in decreased flexibility of the adjacent joints. Diseases of the heart, lungs, liver, kidneys, and ovaries may also cause swelling of the lower limbs, and they are more common than bladder cancer.
