ALBANY, N.Y. -- The bride wore a white dress, black leggings, a veil and carried a bouquet of pink and purple flowers. The groom wore a tuxedo T-shirt with a boutonnière, and had to get on one knee to take pictures with his bride, who is all of 4 years old.

Abby has Pre-B Cell Acute Lymphoblastic Leukemia, according to her Facebook page.

He got "married" to his patient in front of most of the Melodies Center staff, his patients mother and others lucky enough to be around observing.
