Soft-Tissue Sarcoma (STS)

In 2019 about 12,750 people will be diagnosed with STS in the United States

SOFT-TISSUE SARCOMA (STS) is a group of cancers that begin in the connective tissues, there are a dozens of subtypes arising from cartilage, muscle, blood vessels, nerves, and fat. This is why STS can occur almost anywhere in the body.

STS are rare, less than 1% of all cancers, diagnoses predominate over bone sarcoma and most commonly occur in the extremities. Morbidity and mortality rates have significantly reduced over the past half century due to advances in surgical techniques, adjuvant therapies, and diagnostic modalities.

The first sign of a sarcoma in an arm, leg, or torso may be a painless lump or swelling. However, it’s important to talk with your doctor about any lumps that are larger than 2 inches (5 centimeters), grow larger, or are painful, regardless of their location. People with a sarcoma that starts in the abdomen may not have any symptoms, or they may have pain or a sense of fullness.

Because sarcoma can develop in flexible, elastic tissues or deep spaces in the body, the tumor can often push normal tissue out of its way as it grows. Therefore, a sarcoma may grow quite large before it causes symptoms. Eventually, it may cause pain as the growing tumor begins to press against nerves and muscles.
Sarcomas that arise in the uterus can cause uterine bleeding or an increase in the size of the uterus. Tumors that start in the heart or a lung may cause breathing problems or pain in the chest.

If you are concerned about any changes you or your child experience, the Institute of Interventional Oncology (IDOI México) recommends you to talk with your doctor to help you figure out the cause of the problem.
