Studies have shown that a cold virus can kill cancer cells

A small clinical study in the UK has shown that a common virus that causes cold symptoms has the ability to target infections and kill tumor cells in bladder cancer, and that a patient involved in the trial had even lost signs of cancer altogether.
researchers at the University of Surrey and others recently reported in the American Journal of Clinical Cancer Research that they recruited 15 patients with non-muscle immersive bladder cancer to participate in the trial. A week before surgery to remove the tumor, the patient received an injection of the virus called CVA21 through a bladder catheter.
, the CVA21 virus infected cancer cells in the subjects, and the virus repeatedly copied itself and caused the cancer cells to rupture and die. Once a cancer cell infected with the virus dies, the newly replicated virus continues to attack other cancer cells. A week after the injection, most of the subjects had cancer cells in their bodies that were dead, and one patient was operated on and could not even find signs of cancer in the body.
cells with bladder cancer are good at "disguising" and can evade the "surveillance" of the immune system and are difficult to treat. The study showed that the CVA21 virus can highly selectively infect cancer cells without affecting other cells. Viral infections can also stimulate the immune system, allowing immune cells to quickly gather near lesions and kill cancer cells.
Pandeha, a professor at the University of Surrey, says non-myocardial invasive bladder cancer often requires long-term invasive treatment, and conventional therapies are ineffective and toxic for many patients, and the CVA21 virus is expected to drive changes in the way the cancer is treated.
, CVA21 virus usually through the respiratory tract or digestive tract infection of the human body, resulting in fever, sneezing, cough and other cold symptoms. This study confirms its potential as a lysovirus. Lysovirus is a virus that specifically kills cancer cells and does not harm normal cells. Nigula Ayers, a researcher at the University of Surrey, commented that lysolysis viruses such as CVA21 "may change the way we treat cancer." (Source: Xinhua News Agency)
