Hi Joarden, I just posted this on a Scan thread and thought it might provide some perspective on your concern about treatment timing:
Links to three resources for insight into general growth rate and cell estimation for BC tumours:
1.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320224/
From start of 7th para: 'The number of cancer cells is a function of
tumour volume in cubic centimetres. Each cell is about 20 μm in
diameter. A 1-cm cancer has about 100 million cells, a 0.5-cm cancer has
about 10 million cells, and a 1-mm cancer has about 100 thousand
cells.'
Near
the end 'Scientists have found that for most breast and bowel cancers,
the tumours begin to grow around ten years before they're detected.'
