Cancer of the Knee
It turns out that my cousin has had a lump the size of a walnut sitting on the back of her knee for the past two years but was afraid to get it checked... and now it's the size of a tennis ball and wrapped around her vascular system. She went in and got the official word - it's cancer. She'll be starting chemotherapy on Tuesday. Unfortunately, due to the way it's wrapped around in there, they can't operate on it. If the chemo doesn't work, she may lose her leg.
The day just gets better and better.
