Hey Jeffrey! I'm so excited for our trip to Alaska in four months!
But Tommy, you know I have skin cancer
Three months ago at the vet...
I'm sorry to tell you this but Frogrick has skin cancer. The good news is we can start the treatment today
My name is Jeffrey not Frogrick...
Let's go to the vet again. She can check if you will be okay to go to Alaska!
At the vet...
Well that depends on how effective the treatment is. The cancerous cells need to be decaying at a high enough rate that there will be less than 12% the initial amount by then.
Do you think Jeffrey will be ready to go on our vacation in four months?
Let's take a look! Wow! The cancerous cells are decaying at an exponential rate! They have already reduced to half their initial population which was 18 billion cells!!!
That's not fast enough for Alaska!!!
After three months, Tommy and Jeffrey go back to the vet for a checkup
The cancerous cells are now at population of 4.5 billion!! That means that the average rate of change since your last visit is 1.5 billion cells per month! In fact, at this very moment, this cells are decaying at a rate of 1.04 billion cells per month!
