I Have Question About How The Base Of My Saguaro Looks, As Far As Being Concerned Or Treatment Needed.

I’m in Yuma, AZ. and pictures will show 10-12 ft tall Saguaro, that is about 15+ years old. For several years we’ve noticed the scaring (scab?) around the base, and thought maybe normal. But the picture will also show, above the scaring appears to be some orange speckles. Should I be concerned or do you have suggestions. THANKS VERY MUCH

Those spots could be from insect feeding, fungal infection, or more. These articles should help:
