Oncotype DX rest Details Colon Cancer

Hi, I have been diagnosed with colon tumor and the same has been removed through surgery 3 weeks ago. Pathology report says T3, M0 , N0. I understand with doctor discussion that fortunately it’s not spread to any lymph nodes. But still doctor advised me to go for chemo. I’m lot worried about side effects of Chemo. I would like to know whether Oncotype DX test can be done India. If so could anyone share the details please? Very much grateful for your quick response. Thanks- Suresh
