It is more common for cancer patients to have swollen feet. It is not necessarily a sign of death, but may also be caused by poor blood return to the lower extremities. Also patients may have poor kidney function, which can also lead to swollen feet. Cancer is a consumptive disease and if the consumption is relatively high, it will cause hypoproteinemia, which will also lead to swollen feet. Therefore, we cannot judge whether the swollen feet are a harbinger of death or how far the patient’s disease has progressed based on the swollen feet alone. Generally a whole body examination is done, mainly imaging examinations, combined with tumor markers and other examinations. Another is routine physical examination to see the patient’s physical status and determine the progression of tumor disease. Cancer is a more consuming disease. Generally, increasing nutrition and improving body resistance also help to fight against tumor and can prolong the survival period.
