The use of
nutritional supplements in the general population and in cancer patients has
become very popular.
These supplements are not perceived as medications and are presumed to be safe
by cancer patients, who may however be at risk for hypercalcemia.
We note that many of our patients who have developed symptomatic hypercalcemia
were taking vitamin D, calcium, or shark cartilage supplements.
We report eight cases of hypercalcemia in cancer patients seen at the Cleveland
Clinic Foundation in whom these nutritional supplements may have contributed to
the prevalence or severity of hypercalcemia.
