Total number of cancer cells inside a tumor: 100Each cell has a 10%

  1. Jan 25, 2012 #1
    Total number of cancer cells inside a tumor: 100
    Each cell has a 10% chance of dying each time it divides
    The rate at which a cell leaves the mass is 1 every 8 hours
    The rate of division is 1 division / 2 hours

    whats the time needed to attain the 100 cells in the first place?
    What is the function that I could put in excel or matlab to figure this out quickly?

    Not very good with coming up with the function.

    I have the following:

    0hrs x0 = 100
    2hrs x1 = x0*0.90+x0
    4hrs x2 = x1*0.90+x1
    6hrs x3 = x2*0.90+x2
    8hrs x4 = x3*0.90-1+x3

    Thanks
