Why Blood Clots Are More Common With Cancer?

“Blood clots are common in all cancers,” says Jacques-Pierre Fontaine, MD, a chest surgeon at Moffitt Cancer Center in Tampa, Florida. “Having lung cancer surgery increases the risk, and we routinely protect patients by giving them blood thinners after surgery.”

Having cancer increases blood clotting in ways we don’t completely understand — but “anything that increases blood clotting increases the risk for DVT and embolism,” says Dr. Raftopoulos.

Here are some ways that cancer and cancer treatment can raise blood clot risk:

1.Cancer cells may release chemicals that stimulate the body to produce more clots.
2.Chemotherapy may damage blood vessels or reduce the production of proteins that protect against clotting.
3.Some cancers produce substances called mucin, which increases blood clotting risk. Cancers that produce mucin include lung, pancreas, bowel, stomach, and ovary.
4.Pain and fatigue from cancer may lead to less activity. Lack of movement allows for more blood clotting.
