About 10%~15% of people with renal cell carcinoma will have high blood pressure, which may be related to paraneoplastic syndrome, tumor compression of arteries, formation of arteriovenous fistula in tumor, and so on.
1. Paraneoplastic syndrome: it is a kind of extra-renal manifestation of renal cell carcinoma, which is caused by the lesions of other organs due to the products of renal cancer, and it mainly manifests as high blood pressure, fever, emaciation, abnormal blood test and so on, which is usually without specificity.
2. Tumor compression of artery: if renal cell carcinoma leads to compression of renal artery, it can cause renal ischemia and thus hypertension.
3. Formation of arteriovenous fistula within the tumor: at this time, it can lead to the increase of cardiac output of the heart, which can lead to the elevation of blood pressure and hemorrhagic hypertension.
It is recommended that the relevant people should consult the doctor in time, and carry out treatment after clarifying the cause of the disease.
