Which of the following is most important property of malignant tumors?
Thus, characteristics of malignant neoplasms include: More rapid increase in size. Less differentiation (or lack of differentiation, called anaplasia) Tendency to invade surrounding tissues.
What is the likelihood that Kaposi sarcoma will spread?

What is the treatment for Kaposi sarcoma?
Treatment. The type of radiation used and the locations of lesions being treated vary from person to person. When more than 25 lesions are present, chemotherapy with standard anti-cancer drugs may be helpful. Chemotherapy is also used to treat Kaposi’s sarcoma in the lymph nodes and digestive tract.
Where do lesions appear in Kaposi’s sarcoma?
Lesions can also appear in the genital area, mouth or lymph nodes. In severe Kaposi’s sarcoma, lesions may develop in the digestive tract and lungs. The underlying cause of Kaposi’s sarcoma is infection with a virus called human herpesvirus 8 (HHV-8).
How does HHV-8 cause Kaposi’s sarcoma?
In healthy people, HHV-8 infection usually causes no symptoms because the immune system keeps it under control. In people with weakened immune systems, however, HHV-8 has the potential to trigger Kaposi’s sarcoma. People infected with human immunodeficiency virus (HIV) — the virus that causes AIDS — have the highest risk of Kaposi’s sarcoma.
