Cancer and blood calcium levels

Calcium is an important nutrient that our bodies need. Having cancer can affect the amount of calcium in the body.

High blood calcium levels are called hypercalcaemia. This usually happens in advanced cancer and is rare in people with earlier stages of cancer.

Having high calcium levels in your blood is called hypercalcaemia. It is a serious condition. Your doctor will need to assess you, to make sure you get the right diagnosis and treatment.

Some cancer treatments can cause low calcium levels in the blood. This is called hypocalcaemia.

There are lots of organisations, support groups and helpful books to help you cope with symptoms and side effects caused by cancer and its treatment.
