Can stomach cancer cause fever? These 3 situations will

Generally speaking, gastric cancer can cause fever. There are three main situations that can lead to fever. One is that cancer cells affect the body's ability to regulate body temperature and cause fever. Secondly, most patients will have a decrease in immune function due to the tumor itself, especially patients with low immunity often have fever. Drug reactions, autoimmune diseases, insufficient secretion of adrenal hormones or cancer itself can also cause fever.

After suffering from gastric cancer, the cancer cells in the body are damaged to a certain extent, so the body's immune system will be damaged to a certain extent. Therefore, the most direct manifestation at this time is fever. So what are the causes of fever caused by gastric cancer? Let us learn about it together.
1. Cancer cells cause fever <br/>Cancer cells affect the body's ability to regulate body temperature, which can cause fever. The most common causes of fever in cancer patients are bacterial, viral and fungal infections. Patients have low immunity and are prone to infectious diseases, the most common of which is respiratory tract infection. Cancer patients often use some special drugs, such as bleomycin, cisplatin, interferon, interleukin, zoledronic acid, etc. These drugs are common side effects. There are also pyrogenic reactions related to blood transfusions and blood products that can cause fever, such as albumin infusion, blood transfusion, etc.
2. Fever caused by decreased immune system <br/>After suffering from gastric cancer, the body's immune function will be decreased, which will lead to fever after central brain metastasis. When the temperature regulation center of the hypothalamus is heated, the heating is rare and can be used for brain CT or MRI diagnosis. Chemotherapy may also cause fever, mainly caused by radiation pneumonitis. Patients with esophageal cancer, lung cancer, and mediastinal tumors can often undergo radiotherapy. The radiation dose and accumulation can cause radiation lung damage, thereby causing radiation pneumonitis, which can be diagnosed based on medical history, physical examination, and chest X-ray.
3. Fever caused by drug reaction, leukocytopenia, etc. <br/>After suffering from gastric cancer, most gastric cancer patients will have leukocytopenia, and about 70% of leukocytopenia patients are caused by infection. Corticosteroids are used for long-term use in brain tumors or certain specific cancers. Crisis caused by the use of adrenal hormones. When excluding the cause of infection, the possibility of tumor fever must be considered. Late tumor fever is common in tumors, fever of malignant tumors, local inflammation of tumor tissues, and excessive heat generated by tumor cells.
