Actress Olivia Newton-John has announced she is suffering from breast cancer for a second time which has spread to her sacrum bone.
But what is the sacrum bone and how can back pain be a sign of breast cancer? Here’s all you need to know…
What is the sacrum bone?
The sacrum bone is a large wedge triangular shape bone that is at the bottom of the back.
It forms the base of the spinal column and intersects with the hip bones to form the pelvis.
The sacrum is one of the strongest bones in the body as it supports the weight of the torso and spreads it across the pelvis and legs.
Actress and singer Olivia Newton-John has revealed that her breast cancer has spread to her sacrum bone in her back.
How can back pain be a sign of breast cancer?
Although rare, experiencing pain and discomfort in the back can be a sign of breast cancer.
Pain that comes from the back and feels as though it is coming from deep within the bones can be a signal of the disease.
In these cases, it is usually because the cancer has spread from the breast and into the bones and shows that the condition is becoming advanced.
However, back pain alone is not always a symptom of breast cancer, and can be just down to soreness or aches in the muscles.
But if the pain is unusual and does not go away, you should see your doctor.
