Hi there, I was diagnosed with dcis in April and had a lumpectomy. I'm currently having chemo. My suggestion to you is to go into the doctors armed with every question swirling through your head. Ask what is likely to happen if you don't have treatments as well as what they recommend and why. Take as much time as you need to go through it all will your doctor. I personally wrote down the answers so that I could go through them later. You need all of the answers so that you can make an educated decision about your health. If you need to get a second opinion, then do so. I also found that what they thought was going to be needed kept changing until I had the surgery. It was like the magic pudding. The whole thing just kept getting bigger. Ask them why they want to take the breast and go through what is likely to happen if you don't. Having facts may make that decision easier. I remember asking what would happen if I didn't have surgery and looked into holistic therapies. My breast surgeon told me I would die. I was grateful for his honesty and directness. It was what I needed. Same with the chemo. I hate it and every part of me screams to stop doing it but the fact is without it I have a 50% chance of reoccurance and with chemo and radiotherapy that drops to 10%. Having facts and figures certainly made my decisions easier. Definitely take someone with you to your appointment for support. It is a terrifying process, I think the unknown is probably the worst part of it. Good luck with your appointment and I wish you all the best xoxox
