Breast cancer is one of the common malignant tumors in women, and its development is related to genetic and environmental factors. In addition, if a human breast cancer vaccine is developed later, it should be clarified whether the vaccine recipient is a susceptible group, which can be considered in combination with the genetic test results from a regular hospital and the history of breast cancer in the family. Secondly, economic conditions should be considered, as the newly released breast cancer vaccine is expensive and often requires about four doses to achieve immunization, which is a heavy financial burden for most people. Finally, even if you have received the breast cancer vaccine, you should review your breast ultrasound regularly every 12-24 months to detect and treat the disease as early as possible.
