Oncotype DX: Important Testing for Breast Cancer

Posted by kilkennyfarmwife @kilkennyfarmwife, Jul 4, 2021

Last February I was diagnosed with invasive ductile carcinoma in my left breast. I am 63 years old. The biopsy and the ultrasound revealed my tumor was 1 cm in length and my cancer grade was 2 out of a possible 3. Good news! We were looking to do a lumpectomy. My doctor scheduled a breast image, which revealed tumor to be 1.8 cm and had almost doubled in size. Next a radiologist found precancerous cells in my left breast. I was devastated but made a decision to do a nipple sparing mastectomy. My cancer is not genetic. I was told after my mastectomy no cancer in my lymph nodes, no cancer in my margins. This was great news as I didn’t need radiation nor Chemo. My oncologist then ordered Oncotype DX test to review my tumor. The test came back and my tumor was upgraded from a 2 to a 3. This very aggressive tumor, now requires me to do Chemo. I am stage 1 breast cancer and I am doing chemo.

The reason I am posting this, is that both tests Breast Imaging and Oncotype DX are not always covered by certain insurance policies. These are expensive tests and insurance companies may not cover them. I feel the Oncotype DX test may have saved my life. Most important, please follow your oncologist direction.

As you move through this treatment,, please remember we are here for you. I also had chemo for invasive ductal carcinoma. I also had some surgeries, and radiation, and finally some hormone therapies. I was considered very young and my cancer grade was a 3. Oncotype DX did not exist at the time, so I cannot comment to that. I was later (8 years) tested and found to have a genetic predisposition to several cancers. Which my family had already guessed. All of that being said, cancer treatments can be hard, but do able, and worth the life you gain. I am here to support you in any way that I can. Please reach out, and let us know how you are doing.


Hi @kilkennyfarmwife, I'd like to add my welcome. Several members have had questions about the Oncotype DX test. I see you've also provided insight to fellow members in this discussion:
