The current estimated human population for the planet earth in 2010 is 6,865,300,000 by the United States Census Bureau. The United Nations estimates that world population will be over the 7,000,000,000 mark in 2011. Recent U.N. organized surveys performed in multiple countries have found the average percentage of people who suffer from some sort of cancer is 31%. The American Cancer Society has found similar numbers in its studies of North and South America.

Using these two sources of information. One can estimate that 2,128,243,000 individuals in the year 2010, will have some sort of cancer.
