Rectal cancer may cause elevation of triglyceride and other symptoms. If rectal cancer is suspected, relevant examinations should be conducted in regular hospitals in time. Early symptoms of rectal cancer are not obvious, but with the progress of the disease, such as blood in stool, change of bowel habit, change of stool character, etc. To confirm whether a patient suffers from rectal cancer, he/she should undergo several examinations, avoiding to guess by himself/herself because of only one indicator. At the same time, patients with malignant tumors are often combined with dyslipidemia, and abnormal lipid metabolism is not only related to cardiovascular diseases, but also related to the occurrence, metastasis and development of tumors. Abnormal lipid metabolism in tumor patients has many manifestations, for example, some patients have elevated triglyceride values and elevated very low density lipoprotein values, in addition to the decomposition of adipose tissue will also be strengthened, therefore, rectal cancer may cause patients with elevated triglyceride. If you have abnormal lipid metabolism, accompanied by other uncomfortable symptoms, you should go to the hospital in time for examination to confirm whether you are suffering from the disease.
