Cancer Stinks

Today I’m mad and sad. My neighbor just lost her brother to esophageal cancer. Another neighbor just had surgery (again) to try and remove his cancer. And a dear friend, Tonya Jamois (former ICAN President) just got diagnosed with breast cancer. She started a blog called Pink and Plaid Warrior about her journey.
I was at the park when I overheard a little boy, maybe nine or ten years old, say, "I like to burn the hair off Barbies and pretend they have cancer." I'm still trying to wrap my brain around that one. Does his mom (or another relative) have cancer and this is his way of dealing with it? Or is he a real-life, straight off the big screen movie Toy Story, toy torturing Sid? I don't know, but it freaked me out.
Why can't we find the cure for this disease? It can't come soon enough...
