New to TNBC

Lumpectomy surgery is completed, 7 mm tumor, clear margins, no cancer in sentinel lymph nodes. So T1aN0, but aggressive, 8/9 . BUT when the doctor goes through the decision tree for TNBC, it says Consider Chemo, its in the grey area, its in the middle between NO Chemo and Yes Chemo.  I can't get in to see the medical oncologist for a month. Asked for second opinion, and will get a referral.  But how do people make this decision when you end up in the middle like this?

Basically, after years of watching women post similar results, I've learned that the answer is 'go for it', don't hold back on treatment but stay aggressive. If you don't go the chemo route and you have a recurrence it will be that much harder to fight.

The nurse coordinator managed to get me moved up, so I now have visited radiation and medical oncologists. Radiation seems pretty clear.  Chemo still sounds pretty intense. Doc is recommending 4 doses, 3 weeks apart, of Cytoxan and Taxotere. Also found out that these are paired with steroids, which can raise your blood sugar, andI am a borderline type 2 diabetic. After seeing the statistics, where in 10 years, 15% will metastasize and die without chemo, while 10% still will with chemo, I really am struggling with this decision. Any other thoughts from the group?  Thanks for the help.

Tumor was 7 mm, no node involvement, being treated in Bellingham, 100 miles north of Seattle, negative on genetic mutation.
