“Other young women with breast cancer.

Pregnancy after breast cancer.

All of their stories helped,” she wrote.

This is day one of sharing and is going to be a long one.

This first step of acceptance of my reality was the hardest.

But I am ready to fight this.”

Concluding her post, Thurston thanked her “extraordinary husband-to-be” for his continuous support.

“I don’t know how I’d do this without you,” Thurston wrote.

“The selfless love that you smother me in is beyond anything I imagined I’d be blessed with.

I love you to the fullest in this lifetime and the next.”

Later that year, she became the star ofThe Bachelorettes 17th season andaccepted a proposal from Blake Moynes.

Thurston and Arcuri got engaged last year.

“I had a small lump in my breast around the 10 o’clock spot.

I discovered it myself,” she explained.

“I once had a benign cyst removed from that same breast and thought maybe it was that again.

Went to the doc thinking it was going to be nothing.

I was wrong.”
