Data Stream Easing the Cancer Burden for Patients Living With HIV The total number of cancer diagnoses among people living with human immunodeficiency virus (HIV) is projected to decline in the coming decades because of decreases in cases of non-Hodgkin lymphoma and Kaposi sarcoma (known as AIDS-defining cancers). Using data from the Centers for Disease Control and Prevention (CDC) and the HIV/AIDS Cancer Match Study, researchers esti- mated that, compared with inci- dence rates in 2010, total cancer burden will decrease from 7,908 to 6,495 by 2030. 8000 7000 7,908 6,495 6000 The Bad Luck Hypothesis About two-thirds of cancers are caused by random DNA replication errors and many fewer are caused by environmental factors or inherited mutations, suggesting that most cancers are caused by bad luck, according to research published in Science. Researchers studied the associations between the number of normal stem cell divisions and the risk of 17 cancer types in 69 countries, finding that: 66 % are caused by random mutations 29 % are caused by environmental factors 5 % are caused by inherited mutations Source: Tomasetti C, Li L, Vogelstein B.
