10. menopause: lt40, ge40, premeno.

11. tumor-size: 0-4, 5-9, 10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44, 45-49, 50-54, 55-59.

12. inv-nodes: 0-2, 3-5, 6-8, 9-11, 12-14, 15-17, 18-20, 21-23, 24-26, 27-29, 30-32, 33-35, 36-39.

15. breast: left, right.

16. breast-quad: left-up, left-low, right-up, right-low, central.

17. irradiat: yes, no.

18. Missing Attribute Values: (denoted by "?") Attribute #: Number of instances with missing values:

19. 8

20. 1.
