Hi Janet,I personally hate statistics. I never seem to fit the bill.I was told I'd only have an 8% chance of recurrence- bingo! lucky me.Doctors are always going to conferences and updating their info so sometimes they make changes to what they have said previously. It's hard when the goal posts get moved on you -happens a lot with the bc ride. Maybe you need to talk to your onco again to get clarification and get him to write the stats down for you.What you are saying doesn't add up- you are right.I took Tamoxifen for 4 years and yes,I had some side effects.But the worry is more of what it can do that you DON'T know about.You could get changes to your endometrium,blood changes and a fatty liver.Yes,it's an effective drug against bc but we need to be carefully monitored whilst on it.Ask more questions from your team until you feel confident to take this drug.Tonya xx
