What examples do you have in mind? I ask because both of my in-laws passed from very aggressive cancers, but there really isn't much I can point to as meaningful signs. In hindsight, it did seem like a lot of people in their neighborhood also passed from various cancers, but even then they were all different types and I'm not sure it was statistically significant.
