I Would Like to Learn About:

Causes

The exact cause of SFT remains unknown. This type of tumor affects men and women equally.

Symptoms

About one half of the people with this type of tumor do not show any symptoms.

If the tumor grows to a large size and pushes on the lung, it can lead to symptoms, such as:

Exams and Tests

SFT is usually found by accident when a chest x-ray is done for other reasons. If the health care provider suspects SFT, tests will be ordered. These may include:

The diagnosis of SFT is difficult compared with the cancerous type of this disease, called malignant mesothelioma, which is caused by exposure to asbestos. SFT is not caused by asbestos exposure.

Treatment

Treatment is usually to remove the tumor.

Outlook (Prognosis)

The outcome is expected to be good with prompt treatment. In rare cases, the tumor may return.

Possible Complications

Fluid escaping into the membranes around the lungs (pleural effusion) is a complication.

When to Contact a Medical Professional

Call for an appointment with your provider if you notice symptoms of SFT.
