Cancer is a disease, not a virus.

Cancer is a complex group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These abnormal cells can invade nearby tissues and organs, disrupting their normal function. Cancer can arise from almost any type of cell in the body and can occur in various organs and tissues.

There are many different types of cancer, each with its causes, risk factors, and characteristics. Some common risk factors for cancer include genetic factors, exposure to carcinogens (such as tobacco smoke or ultraviolet radiation), unhealthy lifestyle choices (such as poor diet or lack of physical activity), and certain infections (such as human papillomavirus (HPV) and hepatitis B and C viruses, which can cause Cervical cancer and liver cancer, respectively).

Viruses, on the other hand, are infectious agents that can cause a variety of diseases, including some types of cancer. Certain viruses, known as oncogenic viruses, have the ability to integrate their genetic material into the DNA of host cells, leading to changes that can contribute to the development of cancer. Examples of oncogenic viruses include human papillomavirus (HPV), which is associated with cervical cancer and other cancers of the genital and head and neck areas, and hepatitis B and C viruses, which are linked to liver cancer.

In summary, cancer is a disease characterized by the abnormal growth and spread of cells in the body, whereas viruses are infectious agents that can cause various diseases, including some types of cancer.
