Hi dear @entity01.
Hope you are fine. I'm safe and sound too Alhamdulillah. Yes, no doubt breastfeeding can reduce incidence of some cancers like those of breast and ovary. As it strengthen the immunity system of the baby. And immunization is also important for the health of a baby as it makes the immune system strong ro fight with diseases in the future. Best of luck for contest.
