Introduction
Dialysis removes harmful substances—such as serum creatinine and blood urea nitrogen—from the body and is particularly suitable for patients with severe kidney disease. When renal excretory function becomes impaired, toxins cannot be adequately eliminated via the kidneys; dialysis helps alleviate this condition. In contrast, chemotherapy kills tumor cells within the body and significantly reduces tumor recurrence rates, making it one of the most effective cancer treatments available.
Generally speaking, dialysis and chemotherapy are distinct treatment modalities with fundamental differences. Specifically:
Dialysis removes harmful substances—such as serum creatinine and blood urea nitrogen—from the body and is primarily indicated for patients with severe kidney disease whose excretory function is impaired, preventing natural elimination of toxins via the kidneys. Dialysis thus helps alleviate toxin accumulation. In contrast, chemotherapy targets and destroys malignant tumor cells, significantly reducing cancer recurrence rates. It is one of the most effective treatments for cancer and can relieve patients’ symptoms while improving their quality of life. In summary, dialysis and chemotherapy represent entirely different therapeutic approaches; the appropriate modality should be selected based on the patient’s specific clinical condition.
Patients undergoing either dialysis or chemotherapy must pay close attention to dietary management: maintaining a balanced, nutrient-rich diet and ensuring adequate intake of high-quality protein sources—such as lean meat, shrimp, and fish—is essential. Additionally, regular physical activity is recommended to enhance overall resistance and immune function.
