My Blood Calcium was high for years and I was never told, by my then PCP, that was a concern of any kind. I moved to another city and established with a new PCP and he caught that right away. That was the biggest reason he sent me for a lung screening. (Along with my smoking history). He said that was a sign of lung cancer. He was correct. I had a nodule that was confirmed to be adenocarcinoma. He is an internist. Very young, but extremely well educated and I feel he saved my life because of his knowledge. If you feel it should be further investigated, you may want to get a second opinion. Also, I learned that different testing labs get different results because they use different methods. From my experience only, Labcorp always comes back high or low on some of their readings where at Mayo clinic, they have come back normal range. When I questioned the differences, that is what was explained to me. God Bless and I pray for a good outcome for you.🙏❤️
