Statastics are helpful in comparing treatment options, but each case is very different and it is hard to find a lot of specific information that fits one's own characteristics closely. It is also hard to find many studies dealing with stage one cancers. Have you been tested for the Her2 oncogene? Has anyone suggested an Oncotype DX test? (It checks 21 genes and determines a risk of recurrance score and provides some insight into your specific case as compared to their database.) I have found good information on breastcancer.org.
What you say above is good: stage 1, good boundaries (margins), no positive lymph nodes, and estrogen positive. Other factors, such as Her2 positive status or having the BRCA genes can dramatically change what treatment you choose.
Often, with a lumpectomy, radiation is recommended. If you are at higher risk for recurrance, chemotherapy may be indicated. If you are Her2 positive, Herceptin will be considered. Some of the treatments are unpleasant, but they are temporary and when you have stage 1 cancer, you are looking long-term and hoping for a cure. If cancer comes back, it is most often a metastasis and stage 4. That's why you want to beat it now.
I am 48, had a stage one, .5cm tumor, ER/PR+, Her2 positive, clean lymph nodes and margins after a mastectomy a little over a year ago. I took chemo (taxotere, carboplatin and Herceptin) 4 of 6 rounds due to severe and lasting side effects, Herceptin for a year (1 more dose to go!) and tamoxifen that /I will take for 5 years. I am going to my surgeon in Dec. to have a preventative mastectomy on my other breast and then will consider that I have done all that I can. I spent a lot of time researching and discussing treatment options with my doctors and trying to discern the best way to go. I was surprised to see how much leeway that I as the patient was given. I could have said that I want no adjunctive treatment and the docs would have been uneasy, but even that was one of the options on the table. When my Oncotype score came back as a 31 (30-40% chance of recurrance) I knew that I needed to take chemo.
