Change the long one into short: The onset of chronic leukemia is frequently so insidious. it is accidently found when a blood count is obtained for other reasons. Sometimes the patient’s own discovery of a few enlarged lymph notes and firm left quadrant abdominal mass may lead to its diagnosis. ? Get rid of the unnecessary words in a sentence. .
