Oncoviruses.
Smoking is a cancer-causing irritant which can trigger viruses. Smoking can cause allergies which can lead to a weakened immune system.
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).
No. You can't "give" someone cancer. However cancer causing viruses like HPV can be transmitted sexually, but not cancer itself.
The medical term for an agent that causes cancer is "carcinogen." Carcinogens can be chemicals, radiation, or viruses that are known to promote the development of cancer in living tissues.
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.
Viruses can be engineered to specifically target and infect cancer cells, causing them to die. Some viruses can also stimulate the immune system to recognize and attack cancer cells. Additionally, certain viruses have the ability to directly interfere with the replication process of cancer cells, leading to their death.
Viruses can infect a cell (s) without causing cancer, sometimes cancer can occur long after an infection takes place. Cancer is not contagious, so difficult to track.
Bacteria and viruses that cause illness are known as pathogens.
A Carcinogen.
Some can cause cancer. They are called oncogenic viruses.
Viruses are pathogens that cause diseases which leads to cancer.
