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.
