The presence of swollen feet in colon cancer is not clearly related to how long one can live. At this time, patients may live for 1-2 years, and after active treatment, patients may live for 3-5 years. 1. Hypoalbuminemia: swollen legs and feet of colon cancer patients are often caused by hypoalbuminemia due to reduced food intake of patients with advanced stage of cancer. Most of such swollen legs and feet occur in bilateral lower limbs, and after active supplementation of albumin, patients’ swollen legs and feet will get better. 2. Venous thrombosis: Swelling of the feet that occurs unilaterally in the lower limbs is usually due to venous thrombosis. When the presence of venous thrombosis is confirmed, vascular surgery should be actively consulted and anticoagulation therapy should be given accordingly. 3. Tumor metastasis: colon cancer lesions invade liver and kidney, leading to liver and kidney function damage, which can also lead to swollen feet. If the lesions are more limited and there are indications for surgery, surgery can be performed to remove the lesions and relieve the symptoms. If the lesion is more limited and there are indications for surgery, surgery can be performed to remove the lesion and relieve the symptoms. If surgery is not suitable for the patient, the patient can be actively treated with radiotherapy, targeted drugs and immunotherapy, and some of the patients can have a long survival period. Therefore, if you have swollen feet in colon cancer, you should evaluate the cause and treat it actively to get better therapeutic effect. null
