This breast cancer stuff is not easy, at least that has been my experience. It does get better, especially after you meet with the oncologist and get your treatment plan together. That being said, I wish people would have told me that the biopsy and mastectomy were the easiest part of this journey. I am finding that the hardest part for me is the unexpected things that happen, like side effects from meds.
Take some time to breathe and take one step at a time. The fortunate thing about breast cancer is that it is not a death sentence anymore. With all the progress in treatment and research, we don't have that fear anymore. There are ladies with Stage IV cancer that lead productive lives.
The hardest part, as I recall at the stage where you are, is the waiting and not fully knowing what is going on. You just know there is this stuff in your body that is not supposed to be there. Not knowing is the worst. Cancercare.org is a good website to get information about breast cancer as well as the Susan Komen website. The American Cancer Society is great, too. In fact they have resources to help a person financially. A great book that was given to me by the nurse at the clinic I go to is Breast Cancer For Dummies. It explains things so simply and alleviates a lot of uncertainty. For me, information is power. I know for others this is always true. But the more information I have, the more I can know what I need to do.
I wish you well as you begin your journey. You aren't alone.
