Coping physically with cancer

Cancer and blood calcium levels

Calcium is an important mineral that our bodies need to keep us healthy. Having cancer can affect the amount of calcium in the body. High blood calcium levels sometimes happen if your cancer is advanced. It is less likely to happen if your cancer is at an early stage.

It is important to tell the team caring for you if you have symptoms of high or low calcium so you can get treatment as soon as possible. 

There is information here about the symptoms and possible treatments.

Your body and calcium

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

High calcium levels (hypercalcaemia, hypercalcemia)

A high blood calcium level is called hypercalcaemia. This usually happens in advanced cancer and is rare in people with earlier stages of cancer.

Low calcium levels and cancer

A low blood calcium level is called hypocalcaemia. Some cancer treatments can cause low calcium levels.

Resources and support

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