It happened to me too, in 2019. More common then you would like, but some cancers grow faster and its possible for it to be larger then the target area they anticipated. Or so I was told :(. Also no one told me about the lotions for the radiation till my first week was finished! They were out of samples and forgot! So ask ahead of that, as it works best if you have started using it pre treatments. It is unfortunate , but YOU GOT THIS!!! We are warriors! 😉
