I would recommend getting this book from Amazon.

Judy C. Kneece
Breast Cancer Treatment Handbook, 10th Edition (2022): Understanding the Disease, Treatments, Emotions and Recovery from Breast Cancer

It has amazing resources in it including a page helping g you make your decision.

I personally opted for bilateral mastectomy because I read that invasive lobular cancer likes to come back and I didn’t want to think about that. I also wanted reconstruction. And didn’t want two different breasts. Each person has to make their own decision based on their needs and type of cancer. I think this book will really help you. Best wishes for you. 🙏
