Aggressive sarcoma cancer is not that common. Aggressive tumors usually arise from a primitive tissue subtype called "mesoderm." The tumor can affect a very wide variety of tissues and organs in the body across different age groups, from young ones to adults. Aggressive sarcomas may start from soft tissue or bony sites on the body, giving rise to several soft tissue and bony sarcomas. As at today, there are more than 30 different subtypes of sarcomas that are known.

All the different subtypes of sarcoma can affect anyone from different age groups. There is no guarantee that certain age group will be less afflicted with all sarcoma subtypes. Anyone can be afflicted with this rare form of cancers.

Causes of aggressive sarcoma cancer

Causes of aggressive sarcoma differ from patient to patient. For some patients, causes are unknown and no risk factors identified. However, some patients with familial diseases like neurofibromatosis have a higher risk of having one of the associated benign enlargement of nerve sheaths turning cancerous.

Also, a patient with prior radiotherapy has a higher chance of developing aggressive sarcoma around the previously radiated area. However, this often does not happen immediately. It could take up to 10 years before the occurrence.

Symptoms
The most common symptom is a painless lump in the arm or leg. Some patients have reported to doctors complaining of a lump or mass on the trunk, leg or arm. In most cases, however, the lump may or may not be painful. But, the aggressive sarcoma is diagnosed when biopsy, which is the removal of the pieces of tissue, of a lump on the arm, leg or trunk is examined by the pathologist using a microscope. Aggressive sarcoma cancer is a commoner in the shoulder and knee areas than other regions of the body.

As the cancer progress, the patient may experience weight loss, loss of appetite, or prolonged fever. There are other symptoms which are referable to the site of the sarcoma, such as indigestion, feeling of fullness when eating, bleeding from the vagina when uterus sarcoma is present, and gastric pain when a stomach sarcoma is present.

Treatment
Upon examination and it is discovered that a patient has sarcoma localized to the organ of origin, the patient may be require to have surgical removal of entire cancer and a rim of surrounding normal tissue. In some patients, further radiotherapy to the site of cancer may be required after surgery to prevent cancer recurrence at the same site in the future.
