Final answer:
Nasopharyngeal carcinoma is commonly caused by the Epstein-Barr virus, and other cancers, such as cervical cancer and liver cancer, can be caused by HPV and hepatitis viruses, respectively. Helicobacter pylori bacteria can lead to gastric cancer.
Step-by-step explanation:
Nasopharyngeal carcinoma is commonly caused by an infection with the Epstein-Barr virus (EBV). This virus is associated with several other types of cancers, including Burkitt lymphoma, Hodgkin's lymphoma, and gastric cancers. Additionally, other infections that have been linked to different types of cancers include the human papilloma virus (HPV), which is known for causing cervical cancer and other reproductive system cancers, as well as the hepatitis B and hepatitis C viruses, which can lead to liver cancer. Furthermore, Helicobacter pylori, a type of bacteria, has been implicated in the development of gastric cancer.
