Q

Hodgkins Disease

A

Hodgkin disease is a type of lymphoma. Lymphoma is cancer of lymph tissue found in the lymph nodes, spleen, liver, and bone marrow. The first sign of Hodgkin disease is often an enlarged lymph node. The disease can spread to nearby lymph nodes. Later it may spread to the lungs, liver or bone marrow

Q

Kaposi sarcoma

A

Kaposi’s sarcoma is a cancer that causes patches of abnormal tissue to grow under the skin, in the lining of the mouth, nose, and throat or in other organs. The patches are usually red or purple and are made of cancer cells and blood cells. The red and purple patches often cause no symptoms, though they may be painful. If the cancer spreads to the digestive tract or lungs, bleeding can result. Lung tumors can make breathing hard.
