Treat cancer by virus

Virus . also beneficial! At least that's what British scientists plan to do: Use flu viruses and smallpox virus to treat cancer.

British scientists are expected to begin using this virus and smallpox virus this year to conduct clinical trials on people who treat cancer. Previously, the preliminary study results in mice showed that these viruses are effective in eradicating tumors.

Recently, the British " Guardian " quoted Professor Lennard Seymour of Oxford University as saying they need more years of clinical trials to prove their therapeutic efficacy. the above virus.

If successful, a viral cure will become a standard method of dealing with cancer after two chemotherapy and radiation treatments. At the same time, serious side effects can be avoided.

This viral treatment is considered "toxic poisoning". They first tried to put a small amount of virus inside the cancer cell. Because there is no interference of the immune system, the virus will replicate indefinitely, leading to the separation and death of cancer cells.

The virus continues to invade nearby cancer cells and repeat the process.

For a long time, many articles about the ability to kill cancer cells of the virus have been published in scientific research journals. US scientists have also tried directly injecting the virus into the tumor, but by not finding the location of cancer cells, or cancer cells have spread throughout the body, the direct injection method has lost its effect.

Professor Seymour said, they did not use direct injection but through the blood to deliver the virus to the cancerous part. The difficulty of this method is how to ensure that the virus is not destroyed by the body's immune system on the path.

Their approach is " chemical repair " for the virus, wrapping the virus with a polymer cover so that they can " stealth " and avoid detection of the immune system.

When clinical trials on humans, the virus causing the virus and the smallpox virus they use are all treated to reduce the likelihood of causing illness. But Professor Seymour hopes, they will be able to use the untreated virus.
