Answer:
Cancer vaccines prevent infection with bacteria and viruses that cause cancer.
Explanation:
The cancer vaccine aims to stimulate the immune system to be able to recognize and eliminate tumor cells. Unlike normal vaccines, which aim to prevent the occurrence of disease, the cancer vaccine is classified as immunotherapy because it allows the immune system to act on the recognition and destruction of cancer cells present in the person. Understand how immunotherapy works.
Thus, the main goals of the cancer vaccine are:
- Prevents cancer growth and spread;
- Eliminates the tumor cells that are in the body even with another treatment such as chemotherapy, for example;
- Prevents the return of cancer.
Despite the great advantage that the cancer vaccine has for health, it is still under research and testing and there are only vaccines for some cancers. In Brazil, for example, there is only vaccine against cervical, vaginal and vulvar cancer.
