What is Kaposi Sarcoma?

Kaposi sarcoma is a rare type of cancer that affects the skin, lymph nodes, and other organs. It is characterized by the abnormal growth of cells called Kaposi sarcoma-associated herpesvirus (KSHV). This cancer often appears as lesions or tumors on the skin, but it can also affect the internal organs, such as the lungs, liver, or gastrointestinal tract. Kaposi sarcoma is most commonly seen in people with weakened immune systems, such as those with HIV/AIDS or those who have undergone organ transplantation.

Causes and risk factors to consider

The primary cause of Kaposi sarcoma is the KSHV, also known as human herpesvirus 8.
