Your computer needs to determine the 3 billion bases of DNA sequence of 90 trillions cells without causing any damage to healthy tissue. For as single patient there would be more data than exists on the planet. With the very best equipment it takes a few days to determine the sequence of a human genome and it always involves destroying the cell to get the DNA out.
Is it any big thing for a computer to sift through billions of files to find one or two that have a specific code? Of course it might take a few hours, but it's something within its capabilities.
If a doctor can recognize a tumor on a CAT scan, why can't a computer? If the computer can recognize the tumor, then it is probably more capable of identifying each affected cell. A doctor cannot do that.

Basically, the computer would do what the doctor already does, but with much greater precision.
