Cancer occurs when cells in a certain body part grow and divide uncontrollably and form a tumour, and can spread to other body parts. Cancer vaccines train the immune system to shield the body against foreign invaders or abnormal cells. According to oncologists, these vaccines carry an antigen which is similar to the tumour. Once your body is exposed to that, it creates an inflammatory response which can build immunity against cancer. Cancer cells are good at hiding from our immune cells and since the body doesn't recognise them, they are able to grow. Vaccines help the body recognise these deadly cancer cells so that it can fight against them.
Here are cancers that can be prevented by vaccines:
