It is possible for the face of nasopharyngeal cancer to be swollen. If nasopharyngeal cancer patient’s face is swollen, it may be caused by tumor consumption, malnutrition and other factors leading to hypoproteinemia. As nasopharyngeal cancer has the characteristics of infiltration and growth as well as metastasis, the tumor will gradually transfer to other parts of the body along with lymphatic circulation and blood circulation, and the consumption of tumor and malnutrition of patients will lead to hypoproteinemia. When plasma albumin decreases, the effective osmotic pressure will also decrease, causing excessive water retention between tissues, which leads to swelling of the face of nasopharyngeal cancer patients. Nasopharyngeal cancer patients need to actively treat the disease, and most of them will gradually return to normal with the improvement of the primary disease and facial edema. Patients should also strengthen nutrition and monitor plasma protein level. If there are other discomforts in the body, doctors should be informed in time.
