Sadly, between 20-30% of those diagnosed and treated for EBC will go on to have a diagnosis of secondary breast cancer :( Unfortunately, I am one of those people. I had aggressive treatment for EBC in 2008 after I discovered a tiny lump. I had the removal of lymph nodes (3 were affected by bc), but the bc returned in 2011 in my lungs and then spread quickly to my bones. This was despite me living a very healthy life..no alcohol, no coffee, daily exercise, organice hair products, meditation, radical overhaul of my diet and no use of chemicals in my home.
I agree we mustn't live in fear, but at the same time please be vigilant about your health. Insist on follow up scans, especially if you feel something isnt right xx
