Benign soft tissue tumors

A soft tissue tumor is a growth of abnormal cells in the body's soft tissues. These tissues include the muscles, lymph and blood vessels, nerves, and fat. They can also include cartilage and other connective tissues. When a tumor is benign (say "bih-NYN"), that means it's not cancer. Most soft tissue tumors are benign.

Benign tumors don't spread to other tissues and organs. They usually aren't life-threatening. But they can cause problems if they grow too much, press on nerves, or cause pain.

Sometimes a tumor can be felt as a bump under the skin. Or if the tumor is deep enough below the skin, you may not be able to feel it on your child. Your child may also feel pain near the tumor if it's large or pressing on something.

Your doctor will ask you about your symptoms and past health and will examine you. A physical exam can help your doctor diagnose some soft tissue tumors.

Your doctor may find a tumor when taking X-rays or other imaging tests for another problem.

If your doctor isn't sure what the growth is and your symptoms could be signs of a tumor, you will get some tests. The tests can help make sure it's not cancer. They can also help your doctor figure out the best treatment for the tumor.

• You may have one or more imaging tests to get a better look at the tumor. These may include:
  • X-rays.
  • Ultrasound tests.
  • CT scan.
  • MRI scan.
• You may need blood tests and lab work.
• You may need a biopsy so a sample of the tumor can be looked at under a microscope. This sample may also be used to test for biomarkers. They will help with planning treatment.

Doctors may also look at other parts of your body for other tumors.

Some benign soft tissue tumors that aren't causing problems can be watched over time. Some may remain stable or go away on their own. But if the tumor causes pain, is growing larger, or affects your child's movement, it may need to be removed.

You may also choose to have these tumors removed if they bother your child or if you and your child don't like how they look.

Doctors may remove some tumors with surgery. In some cases, other treatments, including medicines, may be used.

Talk with the doctor or specialist about other types of treatments for your child's tumor. After treatment, the doctor may want to check the area again to make sure that the growth doesn't come back.

Your care at home may depend on whether the tumor is causing pain or other problems. Take any medicines as prescribed. If surgery is needed for treatment, follow any instructions about activity and medicines after you return home. Go to any follow-up visits with your doctor.
