Once an abnormality is noted, forst we need to know of there if it is of any significance or not. Not all problems are of significance. Some findings are normal in a newborn but when seen in a fetus they may be considered abnormal and may only require follow up. If it is a significant problem then the family is counselled about it and whether it is treatable, or not or even whether it requires consideration for ay treatment. Because not all problems require treatment.
