While your treatment is vital to fight your cancer, it may also increase your risk of blood clots. Treatment such as surgery andn chemotherapy (a type of cancer treatment that uses one or several drugs in combination) can damage the walls of the blood vessels affecting the way they function. This can also lead to a blood clot. When chemotherapy kills cancer cells, certain substances that can cause clotting are released into the blood stream. Some types of chemotherapy drugs are less likely to promote clotting than others.
It is recommended to discuss this risk with your doctor so that you can be informed of any risks associated with the treatment you have been prescribed. This is also an important consideration for caregivers of cancer patients.
