What is Cardiac Sarcoma?
Cardiac sarcoma is a very rare cancer that starts in the tissues of the heart. It develops when abnormal cells grow uncontrollably in the heart muscle or blood vessels.
Some tumors begin in the heart itself, while others spread there from cancer in another part of the body. Because it is uncommon and often silent early on, it may not be found until it has already grown or spread.
Symptoms
Symptoms can vary depending on where the tumor is located and how it affects blood flow or heart function.
Common symptoms may include:
- Chest pain or pressure
- Shortness of breath
- Feeling very tired
- Swelling in the legs, ankles, or abdomen
- Irregular or fast heartbeat
- Coughing up blood
- Hoarseness or facial swelling
Some people may also experience whole-body symptoms such as fever, night sweats, or unexplained weight loss. In certain cases, pieces of the tumor can travel through the bloodstream and block blood flow, which may lead to serious complications like stroke.
The exact cause of cardiac sarcoma is not known. It develops when heart cells begin to grow uncontrollably. There are no clear risk factors or proven ways to prevent it.
How is it diagnosed?
To diagnose cardiac sarcoma, your provider will begin with a physical exam and review your symptoms and medical history.
Imaging tests play a key role. An echocardiogram is often the first step and allows providers to see how the heart is working and whether a mass is present. Additional scans, such as CT, MRI, or PET imaging, may be used to assess the tumor’s size better and whether it has spread.
Other tests, such as an electrocardiogram (ECG), can detect changes in heart rhythm. A biopsy—removing a small sample of the tumor—is needed to confirm the diagnosis.
How is it treated?
Treatment depends on the tumor’s size, location, and whether it has spread.
When possible, surgery is the first option. Surgeons may remove the tumor through open-heart surgery. In some cases, chemotherapy may be used after surgery to help reduce the chance of the cancer returning.
If the tumor cannot be fully removed, other approaches may be considered. These can include radiation therapy, chemotherapy, or specialized procedures such as a heart transplant or reconstructive surgery.
When the cancer has spread, treatment often focuses on easing symptoms, improving quality of life, and helping you live longer. Your care team will work with you to create a plan that fits your needs.
