A vascular tumor embolus is the presence of tumor cells in the circulatory system when tumor cells invade the lymphatic vessels and blood vessels, causing tumor cells to appear within them.
The tumor in the primary focus forms an embolus that is dislodged and enters the blood vessels, where it is transported to various locations as the blood circulation proceeds, blocking the vessels.
Normally, the embolus formed after the tumor embolus is dislodged can embolize to different locations with blood circulation, but because venous blood flows back into the right atrium and eventually enters the lungs, it is more common for the tumor embolus to lead to embolism of the pulmonary artery.
To sum up, vascular tumor embolism refers to tumor cells invading the vascular system. If you have any discomfort, it is recommended that you consult a doctor in time and follow the doctor’s instructions.
