What is the cause of swollen feet in late stage lung cancer

What is the cause of swollen feet in late-stage lung cancer?

Foot swelling in the late stage of lung cancer can be caused by hypoproteinemia, tumor metastasis, cancer thrombus in the inferior vena cava, renal complications, etc.

In patients with advanced lung cancer, tumor growth will consume a large amount of albumin, leading to hypoproteinemia, and then causing a decrease in plasma colloidal osmotic pressure, resulting in symptoms of swollen feet due to advanced lung cancer, mainly manifested as depressed edema.

Second, tumor metastasis. The tumor metastasizes to the abdominal cavity and compresses the blood vessels of the lower limbs, especially the veins, which can lead to poor venous return and cause symptoms of foot swelling in the late stage of lung cancer.

Third, inferior vena cava cancer thrombus. Inferior vena cava cancer thrombus can also cause poor venous return in the lower limbs, and can also cause symptoms of swollen feet in the late stage of lung cancer.

Fourth, there are renal complications. If patients with advanced lung cancer receive chemotherapy, especially the use of platinum drugs, renal damage may occur, leading to changes in glomerular filtration rate, which in turn leads to the symptoms of swollen feet in advanced lung cancer.

In addition to the above-mentioned swelling of the feet in the late stage of lung cancer, there may be other reasons, such as long-term tumor consumption. It is recommended to go to the hospital for treatment in time, complete the examination, clarify the cause, and give targeted treatment or treatment under the guidance of the doctor.
