First Oncology Consult and Oncotype Result

I had my first consult with an oncologist today and I received my oncotype, which typically takes about 2 weeks to get after surgery. Oncotype DX is a genomic test used to determine the recurrence rate in early-stage hormone-positive (HR+) breast cancer.  It works by analyzing the expressions of 21 genes in a sample of tumor tissue.  The score ranges from 0 to 100, with a higher score indicating a greater likelihood of recurrence.  It also helps determine treatment decisions based on the patient's risk.

If a patient's oncotype score is 15 or less, chemotherapy is not likely to benefit the patient and is not recommended.  A score of 26 or higher indicates chemotherapy is likely to benefit the patient and would be recommended.  An oncotype score of 16-25 is a gray area and the decision to do chemotherapy is made on a case-by-case basis.  My oncotype was 17.  There was no mention of chemotherapy until today, so I was a little shook to find that the possibility of having to do chemo was there all along.  

I got four oncotype results:

1. Node negative
• Distanct Recurrence Risk at 9 years = 5% with AI or Tamoxifen
• Chemo benefit = < 1%
2. Node positive (Premenopausal)
• Distanct Recurrence Risk at 9 years = 7% with AI or Tamoxifen
• Chemo benefit = 2.7%
3. Node positive (Postmenopausal)
• Distanct Recurrence Risk at 9 years = 4% with AI or Tamoxifen
• Chemo benefit = None (<1%)
4. Node Postivie (>= 4)
• Distanct Recurrence Risk at 9 years = 49% 😱with AI or Tamoxifen

Although the surgeon and oncolgist think that it's not likely that my cancer had spread to my lymph nodes, we did not confirm it with a lymph node biopsy.  So assuming a scenario where it may have spread to 1-3 nodes, I would fall into category #2 above.  With a chemo benefit of 2.7%, the oncologist didn't recommend chemotherapy for me.

While I escaped the worst of the treatments, radiation and medication (Tamoxifen) were still on the table.  I still did not want to do either of these treatments.  From what I understood, each of these treatments alone would reduce my risk of recurrence by 50%, so not insignificant.  Without Tamoxifen my recurrence rate is ~15% (it was unclear if that was with or without radiation).  My initial thought was that 15% chance seemed low enough.  I also felt as though I'm a fairly lucky person (ignoring the fact that I got cancer).  Then my oncologist asked, "I know you like to travel.  If you had a 15% chance of crashing, would you get on that plane?" Then he went on to tell me how unplesant metastatic breast cancer is.  Breast cancer typically spreads to the bones, lungs, liver, and brain.  Bone cancer may lead to severe pain.  Lung cancer may lead to difficulty breathing and chest pain. Liver cancer would lead to abdominal pain and loss of essential functions by the liver.  Brain cancer can lead to headaches, seizures, and other neurological problems affecting daily function.  All of these would affect a person's quality of life.  I wasn't afraid of dying but I was afraid of living a life of low quality.  Now he had me scared.  While I did not want to do these treatments, I had not ruled them out entirely.  I was going to make decisions on them after seeing the doctors about them.  I had a consult with the radiology oncologist coming up.  The oncologist recommended that I at least do the radiation, and then think on the Tamoxifen.
