Your mum's surgeon or oncologist can only give you generalized stats for now.Once surgery is done then they will get indepth pathology results and can plan individual treatment. You won't get detailed stats from booklets but rather statements such as: survival from a lumpectomy is the same as for a mastectomy.Back in 2003 with my first bc,I had to decide whether to have sentinal nodes taken or a full node clearance.My surgeon did a calculation based on the size of my cancer from the ultrasound(2cm) and came up with 60% chance it had gone to lymph nodes.She advised she should take them all and you know what - NO cancer cells in any of the 18 nodes! Statistics are a tool to help make decisions sometimes but they shouldn't be taken as gospel.I had to wait 2 weeks before surgery the first time and 3 weeks the second time.That's about usual. If you and your mum are still unsure which surgery to have then just keep asking your doctor questions,keep researching and soon you will get a feel for what is right for your mum.We are all different and what feels right for one women may not for another.It's probably easier when you don't get a choice.
