Monitoring excretion in cancer patients involves regular assessment of renal and liver function through blood tests, such as serum creatinine and liver enzyme levels. Urine tests can also help evaluate kidney function and detect any abnormalities in excretion. Imaging studies like ultrasounds or CT scans may be employed to assess structural changes in excretory organs. These evaluations help in adjusting treatment plans to prevent complications related to impaired excretion.
