• Question: you know how you said that vitamin A cures developing tumors, can it help slow down the spreading of a tumor that has already been formed ??

      Hi @lizzietheboss,

      So what you are talking about here is a process called ‘tumour metastasis’ where cells from a primary tumour break away and begin building a new tumour elsewhere. What vitamin A does (or more importantly its’ breakdown product retinoic acid) is to slow tumour growth by inhibiting something called proliferation where cells divide to make more tumour cells. I don’t think that it vitamin A has been tried in a secondary tumour, but I suspect when we have improved the treatment package with this drug that we would be able to slow down secondary tumours.

      But again this hasn’t been tried yet.
