Cancer patients cannot judge their survival period based on swollen feet, but need to analyze it comprehensively with their own conditions. It is a common phenomenon for patients with advanced cancer to have swollen feet for many reasons. It may be due to poor diet and malnutrition, which leads to low albumin, resulting in fluid leakage and swelling of feet. However, the specific survival period of patients needs to be comprehensively analyzed according to the stage of tumor, patients’ personal constitution, treatment response as well as patients’ mentality and degree of cooperation with treatment. Cancer patients should actively cooperate with treatment and maintain a good state of mind. After the symptoms of swollen feet appear, it is recommended to elevate the lower limbs and let them rest more to reduce the effects caused by swollen feet. Usually, avoid excessive tension and irritability and maintain regular work and rest.
