Blood clots are one of the overlooked risks when it comes to cancer. If you have cancer, then there is a high chance that you may develop painful blood clots. In some cases, it can be an early sign of an undiagnosed cancer. Knowing these signs can help you reduce unnecessary risk in the future.
Why are blood clots common in cancer?
There is no single reason for blood clots. It can happen due to several biological changes happening in your body during treatment. Some tumors can release substances that can make your blood thicker than usual, activating the clotting system. Cancer therapies like chemotherapy or radiation therapy can damage your blood vessels and increase clot formation. Less physical activity during treatment may also increase the risk of clots.
Signs you shouldn’t ignore
Taking timely action for blood clots can prevent several complications.
Swelling in one arm or leg
Cramping in the calf or thigh without injury
Redness over the infected area
Sudden shortness of breath
Sharp chest pain while deep breathing
Who is at a higher risk?
While anyone with cancer can develop blood clots, the risk factor gets even higher if you are:
Diagnosed with cancers with high clotting risks, like pancreatic or brain cancers
Diagnosed with metastatic cancers, where the disease has spread to other parts of your body
Currently going through chemotherapy or hormone therapy
Recently had cancer surgery or a long hospital stay
How are blood clots treated and prevented?
Doctors usually treat blood clots with anticoagulant medications. These medications can stop the existing clots from growing and reduce the risk of new clots. You may have to take these medications in the form of injections or tablets. To prevent them from growing again, doctors may add more doses of blood thinners, especially after surgery or a long period of inactivity. Another way to prevent blood clots is by staying hydrated and performing some light physical activity to keep your blood circulation moving smoothly. In some cases, doctors may also use some compression devices near your affected area to increase the blood flow.
When to seek a doctor’s help?
Blood clots can be really dangerous if they travel to your lungs. So if you experience shortness of breath or coughing up blood in any way, then it is a warning that you should seek quick medical help. Also, sudden swelling or intense pain can be some of the signs that need medical attention.
