many possiblities: While hyperparathyroidism is by far the most common cause of elevated serum calcium, there are many other possible causes. Hopefully your cousin does not have cancer, the next most common cause, but there are still many other possibilities. It is important for your cousin to see a good doctor to find the cause.

High calcium: This could be a case of borderline primary hyperparathyroidism. The tie breaker for me, without seeing the actual lab values, would be a 24 hr urine collection for calcium. If high, your cousin likely has primary hyperparathyroidism.
