Cancer-causing viruses such as HPV cause cancer by altering or changing the genetic makeup of your cells. They change it by adding or deleting a gene or a genetic material. This turns your healthy cells into cancerous cells.
Some can cause cancer. They are called oncogenic viruses.
Viruses are pathogens that cause diseases which leads to cancer.
The pathogens that cause cancer are called, "Carcinogens."
Smoking is a cancer-causing irritant which can trigger viruses. Smoking can cause allergies which can lead to a weakened immune system.
The cancer that was a result of the injection of cell-free filtrate is the most definitive proof that viruses can cause cancer. The difficulty however in observing viruses is one among the many causes of slow development of cancer etiology.
Viruses don't cause cancer...

With our immune systems getting weaker viruses that enter your body cannot be fought off and the result to that is a possibility for cancer.
Virotherapy is a type of treatment that uses viruses to target and kill cancer cells. The viruses are modified to selectively infect and destroy cancer cells while leaving healthy cells unharmed. Once inside the cancer cells, the viruses replicate and cause the cells to burst, ultimately leading to the death of the cancer cells.
Cancer-causing viruses are known as oncogenic viruses or tumour viruses. These viruses can integrate their genetic material into the host cell's DNA, disrupting normal cellular functions and promoting uncontrolled cell growth, which can lead to the development of cancer. Examples of oncogenic viruses include human papillomavirus (HPV), hepatitis B virus (HBV), hepatitis C virus (HCV), Epstein-Barr virus (EBV), and human T-cell lymphotropic virus (HTLV). These viruses can cause various types of cancer, such as cervical cancer (HPV), liver cancer (HBV and HCV), nasopharyngeal carcinoma (EBV), and adult T-cell leukaemia/lymphoma (HTLV).
Cancer is triggered when there is a malfunction in the reproduction of cells. Either there is too much of something or not enough, causing the malfunctioning cells to constantly reproduce, which is later formed into what is known as a tumor.
Francis Peyton Rous was awarded the Nobel Prize in Physiology or Medicine in 1966 for his discovery of tumor-inducing viruses. He demonstrated that certain viruses could cause cancer in chickens, laying the foundation for understanding the link between viruses and cancer in humans.
