The Kaposis Sarcoma is related to hiv and herpes virus. So the risk factors are if you already have one of these two viruses or if you are sexual active without using protection against these stds.
kaposis sarcoma in a tumor that is found on the skin and is cancerous it is often associated with aids, it is often seen on skin as bluish-red or purple bump
Kaposis Sarcoma is caused by the human herpesvirus 8 and affects the skin. It may show up on the skin in the form of tumors or lesions.
Kaposis Sarcoma is a tumor that is cancerous and attacks connective tissues. The virus is often associated with AIDS. It is caused by a disease called Human herpesvirus 8 commonly known as HHV8.
Since Kaposi's Sarcoma is a cancer, it can be treated, but may not be fully cured. There is always a chance of relapse. Treatment options vary, depending on several factors. You can read more about various options here: http://www.cancer.org/Cancer/KaposiSarcoma/DetailedGuide/kaposi-sarcoma-treating-general-considerations
Kaposi's sarcoma is not curable. Although, it can ofter be effectively palliated for many years. Patients with few lesions can often be treated with radiation therapy or cryosurgery.
I believe HIV is a virus the increases the risk of developing Kaposi's Sarcoma.
No one truly knows the cause of Ewing Sarcoma, however scientists have discovered a possibility. All patients have a chromosomal fusion in genes 11 and 22. There are no known risk factors or inherited genetic traits involved.
It is a systemic disease presenting with cutaneous skin nodule due to Human Herpes Virus 8 infection and is now more frequently seen in patients with Aids. Diagnosis is usually made and confirmed by tissue biopsy.
Risk factors for getting the disease or risk factors if you already have the disease?
Statistically: Dependent risk factors require other risk factors to reach statistical significance Independent risk factors are still statistically significant when adjusted for known risk factors
Histiocytic sarcoma or Extraosseous Ewing Sarcoma.
