Pericardial effusion cancer risk?

Generally speaking, tumors can lead to pericardial effusion, but pericardial effusion is not necessarily caused by tumors. It is unscientific to judge whether it is cancer by pericardial effusion alone, because there are many reasons for pericardial effusion. Therefore, it depends on the specific conditions of patients, such as pericardial effusion, which may be related to cancer, benign tumor or idiopathic pericarditis, infectious or tuberculous pericarditis. Therefore, it is not accurate to say whether pericardial effusion and cancer are highly correlated. Because pericardial effusion is likely to be caused by infectious factors, it is necessary to find out the specific cause of pericardial effusion first, and symptomatic treatment under the guidance of doctors can effectively alleviate the patient's symptoms.
