Lumpectomy with radiation or Mastectomy?

I was diagnosed with Invasive Ductal Carcinoma. I was advised I was a good candidate for a lumpectomy. It would require me to have at least four weeks of radiation, plus I will need hormone therapy as the cancer is estrogen positive. No matter what I chose, the hormone therapy will be required, unless I choose to stop due to side effects. I plan to have plastic surgery down the line. My question is how did you choose your choice of surgery? A mastectomy would mean no radiation, but a lumpectomy is less invasive, and I keep some feelings in the breasts. I was told the change of reoccurrence of cancer with these procedures are the same.

Any thoughts or experiences would be appreciated. I keep going back and forth and just get more confused.
