Hi @lovemoon waiting is hard. Our brains can play a few tricks on us too and add to our stress. Can you phone your dr and let them know about the pain you are experiencing. It may be ok and they are comfortable still doing surgery on 20th. With surgery you will have pathology tests too. If there is anything further happening those test results will reveal that. If you have the dcis diagnosis you must have had some pathology results to give that diagnosis. Try not to over think it. It's very hard I know but keeping busy helps, do things that give you joy. Seek support from family and friends. Don't use Google. It just causes stress which you don't need right now. Take in a bit of exercise like walking. It's good for many reasons but also helps with the stress of all this. Take care 💐
