Cancer begins when cells start growing without control. There are several types of soft tissue tumors, and not every type is cancerous. Several benign tumors, noncancerous tumors, are found in soft tissues. However, there are a few soft tissue tumors that show signs of both benign and cancerous tumors. They are called intermediate soft tissue tumors.

Cancer that begins within the tissues that connect, support and surround alternative body structures is soft tissue sarcoma, which is a rare type of cancer. This includes muscle, blood vessels, fat, nerves, tendons and also the lining of your joints. With more than 50 subtypes of soft tissue diseases, some probably have an effect on children, while others have an effect on adults. These tumors are troublesome to diagnose; as a result, they are mistaken for several alternative issues.

Soft tissue sarcoma occurs anywhere in your body; however, the foremost common type occurs within the arms and legs, and within the abdomen. Surgical removal is the most common treatment, though radiation and chemotherapy could also be suggested depending on the scale, type, location, and aggressiveness of the tumor.

Causes of soft tissue sarcoma
In most cases, there are no clear reasons to relate to the causes of soft tissue sarcoma. In general, cancer happens once cells develop errors (mutations) in their DNA. The errors create cell growth and divide of management. The accumulating abnormal cells are a type of a tumor that may grow to invade near structures and these unfold to alternative components of the body.

The style of cell that develops the mutation determines the type of soft tissue cancer. For example, Angiosarcoma which is also called a metastatic tumor begins within the lining of blood vessels, whereas liposarcoma arises from fat cells.

Some styles of soft tissue sarcoma include:

• Angiosarcoma
• Dermatofibrosarcoma protuberans
• Epithelioid cancer
• Gastrointestinal stromal tumor (GIST)
• Kaposi’s sarcoma
• Leiomyosarcoma
• Liposarcoma
• Malignant peripheral nerve sheath tumor
• Myxofibrosarcoma
• Rhabdomyosarcoma
• Solitary fibrous tumor
• Synovial sarcoma
• Undifferentiated pleomorphic sarcoma

Risk factors

• Inherited syndromes
  The risk of soft tissue sarcoma is often seen from one’s parents. Genetic syndromes that increase risks include hereditary diseases, like Li-Fraumeni syndrome, familial adenomatous polyposis (FAP), tuberous sclerosis disease, and neurofibromatosis and Werner syndrome (WS).
• Chemical exposure
  Being exposed to certain harmful chemicals, like herbicides, arsenic, and hydrocarbon might increase the dangers of soft tissue sarcomas.
• Radiation exposure
  Previous radiation treatment for other cancers can increase the danger of soft tissue sarcomas.

Symptoms of soft tissue sarcoma
Soft tissue sarcoma can be seen almost anywhere in the body, and they start as a lump with no other symptoms. As every subtype is different from each other, people have several experiences with symptoms, diagnosis, and treatment.

• A lump which has developed gradually.
• Worsening abdominal pain
• Uncomfortable swelling
• Limited mobility
• A pulled muscle pain
