There are three types of cancer screening for adults in England, and they save thousands of lives each year.
Cervical screening is offered to women aged 25 to 64 to check the health of cells in the cervix. It is offered every three years between the ages of 26 and 49, and every five years between the ages of 50 and 64.
Most women's test results show that everything is normal, but for around 1 in 20 women the test will show some abnormal changes in the cells of the cervix.

Breast cancer screening
Breast cancer screening is offered to women aged 50 to 70 to detect early signs of breast cancer. Women aged 70 and over can self-refer.
Breast cancer screening uses an X-ray test called a mammogram that can spot cancers when they are too small to see or feel. There's a good chance of recovery if the cancer is detected in its early stages.

Bowel cancer screening
There are two types of screening for bowel cancer.
A home testing kit is offered to men and women aged 60 to 74.
Bowel scope screening uses a thin flexible tube with a tiny camera on the end to look at the large bowel. It is offered to men and women at the age of 55 in some parts of England.
