The role of viruses and bacteria in the development of cancer

Recently, there have been some scientific studies proving the role of viruses and bacteria in the development of cancer. Among them are eighteen types of pathogens (Helicobacter pylori, hepatitis B virus (HBV), hepatitis C virus (HCV), Opisthorchis viverrini, Clonorchis sinensis, Schistosoma haematobium, human papillomavirus (HPV), Barr (EBV) virus, Ephthia virus-human cell 1 (HTLV-1), human herpes virus type 8 (HHV-8) and human immunodeficiency virus type 1 (HIV-1), belong to group 1 carcinogens. Further study of the role of viruses and bacteria in the development of cancer is of great importance for the early prevention of cancer. Key words: cancer, viruses, bacteria
