Carbonero recently revealed she was fighting ovarian cancer just weeks after her husband suffered a shock heart attack in training with Porto.
She underwent surgery at the Ruber International clinic in the Spanish capital Madrid to remove a malignant ovarian tumour and she has now returned home.
The 35-year-old took to social media after arriving back home, posting a photo of the flowers she had received.
She wrote: “At home now and everything’s in order.
“At home now and everything’s in order”
“Thank you so much for all the shows of affection that I have received in the last few days.
“I would love to respond to them one-by-one but it’s impossible.
“Now it’s time to get strong and continue.
“Thank you to everyone from the bottom of my heart.”
Local TV programme Ya Es Mediodia, broadcast by Mediaset, reports that Carbonero’s medical team confirmed everything “had gone to plan”.
It added the sport journalist was “strong and in good spirits”.
The Ruber International clinic had confirmed the operation had “been a success without incident”.
Carbonero’s revelation of her ovarian cancer came three weeks after her husband suffered a heart attack in training which could spell the end of his professional career.
Casillas and Carbonero were married in March 2016 and have two sons together, Martin, 5, and Lucas, 2.
Casillas is a goalkeeping legend having won the World Cup and European Championships during 167 caps for Spain.
He had a stellar career with Real Madrid before moving to Portuguese club Porto in 2015.
