Tumors can grow in the heart, but the incidence of tumors in the heart is very low, especially malignant tumors are very rare, the more common are mainly benign tumors, such as atrial mucinous tumors, lipomas, etc. In this case, according to the cardiac ultrasound and the corresponding pathological examination, the location, size and nature of the tumor can be clarified and the corresponding treatment plan can be selected. Cardiac checkups do not include tumor markers or other types of tumor detection, but mainly check the heart rate, whether there is narrowing of blood vessels and whether there are arrhythmias, etc. The checkups mainly include electrocardiogram, cardiac ultrasound, coronary artery CTA and angiography, etc.
