Hi,
I have a question that I can’t figure the answer to.
If chemo is supposed to kill off any stray breast cancer cells floating around in my body how does the tamoxifen work if there aren’t any BC cells left?
Does that mean that my body might grow some new BC cells further down the line after any current pre chemo ones have been killed and, because my BC cells like female hormones, they will grow faster if I don’t turn my female hormones off by taking the tamoxifen?
If the answer is yes, how and where would those BC cells grow from/appear from then? Presumably not in my left breast because its now missing. Would they appear in my right breast because how would they be BC cells if they dont originate in my breast.
If not in my breast and those new BC cells could appear anywhere in my body would any growth, say in my kidney, be a BC secondary and hormone receptive?
Presumably “other” cancers are not female hormone receptive and the tamoxifen will only help to prevent me getting a secondary cancer from BC and not a primary, new and therefore unrelated cancer say in my kidney or are any cancer cells my body might make in the future likely to be hormone receptive?
Sorry this might be a bit confusing, just trying to work out the point of tamoxifen and how it works if chemo is supposed kill off any stray cells.
Hope someone can understand where my mind is rambling and answer my questions.
