A great-grandmother from Pennsylvania who recently completed radiation treatments for breast cancer won $5 million on a scratch-off state lottery ticket that she only bought because a scheduled family trip didn't go as planned.

Donna Osborne, 75, scored the big prize last month when she bought a $50 'Monopoly Own It All' ticket while buying gas at a convenience store in Lancaster County, where she lives. Osborne said she had previously bought a $5 lottery ticket that won her $50, so she used that money to get another ticket.
