Pancreatic cancer with blackened and swollen face is considered to be related to bile duct obstruction and metastasis of cancer cells to kidney area. 1. Generally, pancreatic cancer patients with mild condition will not have symptoms such as black face and swelling. However, when the disease progresses further and the tumor compresses the surrounding organs and affects the function of the surrounding organs, symptoms of biliary tract obstruction may appear, such as yellow staining of skin and mucous membranes, clay-colored stools, itching of skin, pain in epigastric region, high fever, etc., which may also be manifested as darkening of face. 2. For the phenomenon of facial swelling, it is considered to be caused by cancer cells invading into kidneys. Apart from facial swelling, it may be accompanied by other symptoms such as hematuria, proteinuria, elevated blood pressure, etc., which may affect the quality of life and health. 3. In addition to the above factors, the application of chemotherapy drugs, radiotherapy or not paying attention to skin care during treatment, drinking a lot of water, etc. can also cause darkening and swelling of face in some patients. It is suggested that people with pancreatic cancer who have blackened and swollen face should have further detailed examination so as to clarify the cause of the disease and take treatment measures according to the doctor’s instruction. Pay attention to skin care in daily life, keep physical and mental happiness, and actively cooperate with doctor’s treatment.
