Lucas D'Onofrio's girlfriend was diagnosed with Non-Hodgkin's Lymphoma in February 2015.
They have been together for six years and after her sixth and final session of chemo, he decided to pop the question with all of her family and friends in waiting and a photographer cleverly disguised behind a screen.
In the video, he nervously waits for her in her room at Boca Raton Relational Hospital in Florida, with Ed Sheeran singing in the background. Then he asks her those all-important four words and everyone begins to filter in to share their happy news.
Let's face it- if they can beat cancer together- this couple can handle anything that life throws at them.
Congratulations guys!
