Awaiting a Phone Call

I am not sure what to expect, but Justin and I have a theory I want to run by Dr. Bentz before I make any decisions with Dr. Akereley. I am awaiting a phone call from him as he is out of town.
Our theory is this. Nine years ago I had a mole removed right under my jawbone on my left side. Cancer showed up two years ago in the same area. I had a tumor (benign) removed from the middle of my back 5 years ago and now I have another tumor there (supposedly cancer). Is there any chance this isn't coincidence? We think not. We want to do a biopsy to hopefully prove that this hasn't metastasized. We are willing to be proven wrong and be in exactly the same position they say I am in. So, it is not a risk to us to do this, right? Dr. Akereley saw the tumor in my back and immediately assumed it was cancer spread through the bloodstream. I'm not so sure that is the case. I don't think I will rest easy until I know.
I know it might look like we are grasping for straws here, but I need to know this if I am going to go through grueling and possibly life threatening treatments!

On a somewhat lighter note, tonight we took the kids to Brooklyn's school for the Fair they had to raise money for the school. On our way, Wyatt stepped in front of the stroller and ended up tripping because the wheel of the stroller hit his foot. He fell flat on his face and scraped his forhead, nose, and upper lip. Poor thing, he hit really hard because his hands were full and didn't get a chance to catch himself. It looked like it hurt really bad. He's a trooper, but I know it is hurting him. Not enough to turn around and go home. As long as we kept him busy winning candy and toys, he forgot about it. Brooklyn and Wyatt ended up with cotton candy, candy, and cupcakes. Great night for the kids. They were on a sugar high though!
