7 Facts About Sarcoma Cancer

Sarcoma is a form of cancer. Sarcomas are cancers that start in bone, muscle, connective tissue, blood vessels or fat, and can be found anywhere in the body.

In general, there are two types of sarcoma: soft tissue sarcoma and bone sarcoma with more than 50 different subtypes.


Facts About Sarcoma

Can develop anywhere in the Body

While it’s most commonly found in the arms and legs (50-60% of cases), a sarcoma tumor can grow anywhere in the body. Common areas tumors grow in include the legs, hands, arms, head, neck, chest, shoulders, abdomen and hips.

Predominant in children

Adult cancer cases are rare and make up only 1% of all adult cancer diagnoses. More common in children, every year the United States estimates that between 1,500 to 1,700 children will be diagnosed with sarcoma. It accounts for about 1% of adult cancer cases and about 15% of childhood cancers.

Cause is Unknown

Because this type of cancer is so rare, the cause is relatively unknown. Many scientists believe that there are certain factors that can increase your risk including:

  • Being diagnosed with Paget’s disease (a bone disorder)
  • Genetic disorders like neurofibromatosis, Gardner syndrome, retinoblastoma or Li-Fraumeni syndrome
  • Being exposed to radiation from another cancer
  • Exposure to vinyl chloride, arsenic, dioxin and herbicides that contain high doses of phenoxyacetic acid may also increase risk of sarcoma.
  • Additionally, researchers are now studying genetic abnormalities and chromosome mutations as possible causes as well.

Soft Tissue Sarcoma is of Different Types.

There are many different types of soft tissue sarcoma. In fact, there are more than 50 kinds. Some of them, such as liposarcoma that affects fat tissue, are more common in adults. Others, such as rhabdomyosarcoma that affects the skeletal muscles, strike children more often. For some of these cancers, your age can affect your soft tissue sarcoma prognosis. For example, when adults get rhabdomyosarcoma, it’s often harder to treat. Similarly, the adult form of fibrosarcoma, which affects connective tissue, is often more aggressive than the childhood form.

Can be difficult to Detect

It has over 50 different subtypes that can form in multiple locations. This makes detection quite difficult and misdiagnosis is common. In the early stages of soft tissue sarcoma, there are rarely any symptoms besides a painless lump. Detection goes unnoticed until the lump grows and presses on nerves or muscles, which can cause discomfort, swelling, and pain.

Alway Go for a Second Opinion


Because of the rarity of this type of cancer, many doctors have little to no experience in treating this disease. If you’ve been diagnosed, it’s best to get a second opinion and a treatment plan from a doctor who specializes in this rare form of cancer.

Surgery is the main treatment for most soft tissue sarcomas.

Treatment of soft tissue sarcoma usually involves surgery. Amputation was common in the past when treating these cancers in the limbs. Today, amputation is rare thanks to advanced surgical techniques that allow doctors to spare as much as the limb as possible. These limb-sparing surgeries are able to preserve normal or near-normal function and appearance for many patients. Surgeons at high-volume soft tissue sarcoma centers have the expertise to perform these procedures with the best outcomes.
