Yes, get those mammos! But do the self exams, too. That's the only way I found mine. My 3.5cm tumor was lobular, one of the 5% of all cancerous tumors that DON'T show up on mammos! I found it when it finally crept our from under the aerola, a naturally 'bumpy' part of our breats. Lobular tumors DO show on ultrasounds and MRIs. Fortunately, lobular cancer is VERY slow growing and my doctor told me mine took YEARS to get to 3.5cm. It did not reach my lymph nodes, thank goodness, so it was classified stage IIa despite the large size. I was very fortunate, and I had chemo, but I didn't have radiation. I'm on anti-hormone meds for another 4 years, and I'm feeling great (except for my lousy shoulder, which has nothing to do with cancer!).
