Hi ! You general condition of your family member is not very clear from the above. If the pre anesthetic
check up has cleared him for surgery, he should undergo surgery for a hernia
as it might give him more trouble without notice any time. Now a days, anesthesia
and surgery have undergone a lot of improvement in terms of lowering the risks of both. Therefore, I would definitely suggest surgery if he is considered fit by the anesthesiologist and the treating physician. Take care.
