Are you a Carvel Owner with cancer?

My family owned a Carvel for nearly 30 years. During the late 80s, Carvel changed the ice cream mix to now be delivered in bags. These bags came with a warning that the product was "radiated". It may be a coincidence but after carrying those bags against their bodies, my sister suffered from cancer and my father died of pancreatic cancer. I am just wondering if any other people with long term exposure to these items have had incidents of cancer.
