Please try not to be too anxious. Thank goodness you found it when you did. Sounds like you're in good hands now. Keep us posted on how you're doing and let us know how you make out after your tests. I was diagnosed in 2012. Mine was 4.1 cm in 2012 and is now 4.3-4.5 cm. I am going back the end of September for six month check up again. Another CAT scan or echo. Please don't worry and keep us posted on how you're doing it's good to hear from people. It helps all of us when we talk about it I think.
