The American Cancer Society offers a free reminder tool for your mammogram. They'll send you a message when it's time to have a mammo. Here's the link:

As someone who put off her mammogram until it was almost too late, I highly recommend it! If you are going to get breast cancer, wouldn't you rather know it when you are in Stage 0 rather than in Stage 3 like me? Please, my darling friends, try this tool. I love you too much not to pass this on!
