Sample Consultation Using Fuzzy Logic: Rules

if area_of_mass be small_area 
and density_of_mass be high_density  
then
  malignancy := very_likely.

if area_of_mass be large_area and 
   density_of_mass be high_density
then 
  malignancy := very_likely.

if area_of_mass be large_area and 
   density_of_mass be moderate_density
then 
  malignancy := likely.

if area_of_mass be large_area and 
   density_of_mass be low_density 
then 
  malignancy := unlikely.

if area_of_mass be small_area and 
   density_of_mass be low_density 
then 
  malignancy := unlikely.

if roundness_of_mass be certainly_round
then
  malignancy := unlikely.

if roundness_of_mass be deviates_from_round
then
  malignancy := likely.

if lobularity_of_mass be certainly_non_lobular
then
  malignancy := unlikely.

if lobularity_of_mass be lobular
then
  malignancy := likely.
