Alan Rickman's widow issues warning about 'difficult' pancreatic cancer symptoms after actor's death

Rickman, who was known for his roles in "Die Hard," the "Harry Potter" franchise, "Love Actually," "Robin Hood Prince of Thieves," "Sense and Sensibility" and more, died at age 69 on Jan. 14, 2016, after a six-month fight against the disease.

"He had so much more to give. There were so many more things he could have done," she reflected.

Proceeds raised will "help fund life-saving research, campaigning and specialist nurse support," according to the organization.

The disease begins as a growth of cells inside the pancreas; the organ is part of the digestive system, and helps make enzymes to digest food, as well as hormones for managing blood sugar, per the website.
