Tweak tumor size over time algorithm

[depryf]

For diagnosis years 1988-2003 If size = 002 set size to 999 for the following sites lung (340-349) and breast (500-509).

I provided SAS logic that looked like this.

if year_dx in (1988:2003) then do; 
if size = 990 then new_size = 989;
else if size = 1 then new_size = 990; 
else if size = 2 and sitenum (340:349,500:509) then new_size = 999; /* this line is new */
else if size in (401:989,998,999) then new_size = 999; 
else new_size = size; 
end;

Done, this will be available in version 4.10
