Yes: Unless you have been previously diagnosed with cancer- i wouldn't worry about it. Low PTH and low calcium are not typically signs of cancer unless caused by cancer related malnutrition - which is typically obvious. Most likely you just need more vit d (or sunlight) and calcium supplementation. An endocrinologist can help you. Also - malabsorption can cause this -for example post gastric bypass.

Many possibilities: A serum calcium of 10.9 is not far out of the normal range. High calcium that is related to calcium is usually quite a bit higher. I would recommend testing the level of calcium in your urine collected over 24 hrs as well as repeating your labs, including an ionized calcium, which is the amount of calcium in your bloodstream not bound to any proteins.
