I can relate to this from my personal experience of having a sick family member. Five years ago, my father-in-law was diagnosed with Multiple Myeloma, a rare blood cancer. I was close to him and joined several support and information pages on Facebook. Since doing that, I see ads on Facebook and elsewhere targeted to me as if I too had cancer. Now my father in law has passed, yet I still see ads that remind me of the horrible disease he battled.
