Treating hypercalcaemia caused by secondary bone cancer
Secondary cancer cells in the bone can cause calcium to be released from the bones into the blood.
High levels of calcium in the blood (hypercalcaemia) can make you feel sick (nausea), thirsty, drowsy, confused and unwell. It can also cause constipation. You may need to spend a few days in hospital having treatment to reduce the calcium levels.
Your doctor or nurse may ask you to drink lots of liquids. You’re also likely to have a drip (intravenous infusion) of fluids into a vein in your arm. This will increase the fluid/liquid content of your blood, and help your kidneys to get rid of the calcium from your body in your urine.
Your doctor will also give you bisphosphonates through a drip to reduce the level of calcium in the bloodstream. This treatment can be repeated if the calcium levels rise again. You should feel much better within a couple of days.
Bisphosphonates can also be taken as tablets, which may be used to maintain normal levels of calcium in the blood.
