Calcium is an essential mineral that plays a crucial role in many bodily functions, including bone health, muscle contraction, and nerve function. However, when calcium levels in the blood become too high, it can be a cause for concern. High calcium levels, known as hypercalcemia, can sometimes be a sign of an underlying health condition, including cancer. In this blog, we will explore the relationship between high calcium levels and cancer, what causes hypercalcemia, its symptoms, and how it is treated. Additionally, we will discuss why Sahyadri Hospitals is a trusted name for managing cancer and related conditions.
What is Hypercalcemia?
Hypercalcemia refers to an abnormally high level of calcium in the blood. While the body requires calcium for various functions, excessive calcium can lead to complications. The normal range for calcium in the blood is 8.5 to 10.5 mg/dL. When levels exceed this range, it may indicate an underlying issue that requires medical attention.
Calcium plays a vital role in bone strength, muscle function, and the proper functioning of the heart and nervous system. However, when calcium levels become too high, it can affect the kidneys, digestive system, and cardiovascular health. Prolonged high calcium levels may lead to serious conditions such as kidney stones, bone pain, and abnormal heart rhythms.
Can High Calcium Be A Sign Of Cancer?
High calcium levels are not always linked to cancer, but in some cases, they can be. One of the main ways that cancer can cause hypercalcemia is through the release of certain substances that increase calcium levels in the blood. These substances, known as parathyroid hormone-related protein (PTHrP) or cytokines, are produced by cancer cells and can interfere with calcium regulation.
Some types of cancer that are more likely to cause hypercalcemia include:
Lung Cancer: Especially small-cell lung cancer, which can produce PTHrP, leading to increased calcium levels.
Breast Cancer: In advanced stages, breast cancer can metastasize to the bones, releasing calcium into the bloodstream.
Multiple Myeloma: A type of cancer that affects plasma cells in the bone marrow. This can lead to bone destruction and calcium release.
Kidney Cancer: Kidney tumors can sometimes produce substances that increase calcium levels in the blood.
Parathyroid Cancer: This type of cancer affects the glands responsible for regulating calcium in the body, potentially leading to hypercalcemia.
Hypercalcemia in cancer patients is more commonly seen in advanced stages or when cancer has spread to bones. Therefore, it’s crucial to monitor calcium levels in individuals with a history of cancer, especially those experiencing unexplained symptoms like fatigue, nausea, or bone pain.
Symptoms Of High Calcium Levels
The symptoms of hypercalcemia can vary depending on the severity of the condition. Mild cases may not present with obvious symptoms, but as calcium levels rise, more noticeable signs appear. Common symptoms of high calcium levels include:
Fatigue: Feeling excessively tired or weak, even with adequate rest.
Nausea and Vomiting: The digestive system may be affected, leading to a loss of appetite, nausea, and vomiting.
Constipation: High calcium levels can interfere with digestion, causing constipation.
Bone Pain: Hypercalcemia can lead to bone weakening, resulting in pain and discomfort.
Frequent Urination: The kidneys may struggle to manage excess calcium, leading to increased urination.
Confusion or Memory Issues: High calcium levels can affect brain function, leading to confusion, memory problems, or even coma in severe cases.
Abnormal Heart Rhythms: Elevated calcium levels can disrupt the normal rhythm of the heart, leading to arrhythmias.
If you experience any of these symptoms, especially if you have a history of cancer, it’s important to seek medical advice immediately for proper evaluation and treatment.
Causes Of High Calcium Levels
Several conditions and lifestyle factors can contribute to elevated calcium levels in the blood. Apart from cancer, common causes include:
Hyperparathyroidism: An overactive parathyroid gland can result in excess calcium in the blood.
Excessive Vitamin D: Taking too much vitamin D can cause calcium to accumulate in the blood.
Dehydration: Severe dehydration can lead to elevated calcium levels due to the concentration of calcium in the blood.
Medications: Certain medications, such as diuretics or lithium, can raise calcium levels.
Bone Diseases: Conditions like Paget’s disease can cause excessive calcium release from the bones.
How Is Hypercalcemia Diagnosed And Treated?
To diagnose hypercalcemia, doctors will typically perform blood tests to measure calcium levels. Additional tests may be conducted to determine the underlying cause, such as imaging tests (X-rays, CT scans) to check for tumors or bone damage, or tests to evaluate kidney function.
Treatment for high calcium levels depends on the severity of the condition and its underlying cause. If hypercalcemia is caused by cancer, managing the cancer itself is crucial to controlling calcium levels. Common treatments include:
IV Fluids: Hydration with intravenous fluids helps flush excess calcium from the bloodstream.
Medications: Drugs like bisphosphonates or denosumab can help prevent bone breakdown and reduce calcium levels.
Corticosteroids: These may be prescribed if the elevated calcium is caused by certain types of cancer, like lymphoma.
Dialysis: In severe cases, dialysis may be required to remove excess calcium from the blood.
Prevention Of Hypercalcemia
While hypercalcemia due to cancer may not always be preventable, certain lifestyle changes and medical interventions can help reduce the risk of developing high calcium levels:
Regular Screening: Early detection of cancer through regular screenings can help catch potential issues before they lead to hypercalcemia.
Balanced Diet: Avoid excessive calcium and vitamin D supplementation, as these can contribute to high calcium levels.
Hydration: Staying well-hydrated helps kidneys function properly and reduce the risk of calcium buildup.
Monitoring Bone Health: If you have cancer that affects bones, regular bone density scans and monitoring can help manage calcium levels.

FAQ’s
Can hypercalcemia occur without cancer? Yes, hypercalcemia can also be caused by conditions like hyperparathyroidism, excessive intake of calcium or vitamin D, dehydration, or certain medications.
What are the long-term effects of untreated hypercalcemia? Untreated hypercalcemia can lead to severe complications, such as kidney damage, heart arrhythmias, osteoporosis, and impaired cognitive function.
How do doctors differentiate between cancer-related hypercalcemia and other causes? Doctors typically conduct a series of blood tests, imaging scans, and patient history reviews to identify the underlying cause, including cancer, parathyroid disorders, and other conditions.
What are the treatment options for hypercalcemia caused by non-cancerous conditions? Non-cancerous hypercalcemia is treated by addressing the root cause, such as surgery for hyperparathyroidism, rehydration for dehydration, or adjusting medications.
How quickly can calcium levels be reduced during treatment? Treatment for hypercalcemia, especially in cancer patients, can show improvement within hours to days, depending on the severity and cause of the elevated calcium levels.
