Colorectal cancer is the most common form of cancer.

Advanced rectal cancer fever may be caused by a variety of causes, such as infection, tumor progression, immune suppression, etc., which may lead to serious complications and even life-threatening. It is necessary to seek medical attention and evaluate the cause and take appropriate treatment measures. Advanced rectal cancer fever is a common symptom and may be caused by a variety of causes, including infection, tumor progression, immune suppression, etc. Fever itself may not be directly life-threatening, but if not treated promptly, it can lead to serious complications and even life-threatening. The following is an analysis of the risk of fever in advanced rectal cancer: 1. Infection is one of the common causes of fever in advanced rectal cancer. Due to the decline in immune system function in cancer patients, infections such as pneumonia and urinary tract infections are prone to occur. Fever is one of the common symptoms of infection. If the infection is not controlled in time, it may lead to serious complications such as sepsis and septic shock, which may endanger life. 2. Tumor progression may also lead to fever. Advanced rectal cancer tumors may be necrotic, liquefied, and release pyrogenic substances, causing fever. In addition, cancer metastasis to other parts, such as the lungs, liver, etc., may also lead to infection or inflammatory reaction, causing fever.3. Immune suppression is also an important cause of advanced rectal cancer fever. Cancer treatment, such as chemotherapy, radiotherapy, etc., may inhibit the immune system function, making patients more susceptible to infection and fever. 4. Fever may also be related to other factors, such as drug side effects, abnormal body metabolism, etc. Therefore, whether advanced rectal cancer fever is dangerous needs to be evaluated on a case-by-case basis. If the fever is caused by infection, antibiotics and other drugs need to be promptly used for treatment; if it is caused by tumor progression, further treatment may be needed to control the tumor; If it is caused by immune suppression, it is necessary to strengthen immune support therapy. In addition, attention should be paid to maintaining the patient's water and nutrient intake to maintain normal body function. For patients with advanced rectal cancer, if fever symptoms occur, they should seek medical attention promptly, conduct detailed examination and evaluation, so as to determine the cause of fever and take appropriate treatment measures. At the same time, patients and family members should also pay close attention to the changes in the patient's condition, and should inform the doctor in time if there is any abnormality. It should be noted that for patients with advanced rectal cancer, fever may be a sign of deterioration of the condition, or it may be a manifestation of other complications. Therefore, patients and family members should closely cooperate with the doctor's treatment and conduct regular re-examinations and follow-up visits to detect and deal with problems in a timely manner. In addition, patients should also maintain a good attitude, actively face the disease, improve the quality of life.
