Breast screening helps detect cancer at an early stage, often before symptoms appear. As a result, treatment is more likely to be successful and may be less invasive.
In Essex, the NHS invites eligible women and people registered as female with a GP for breast screening every three years. Screening can identify small changes in breast tissue that you cannot see or feel.
You can watch a short video explaining what happens during breast screening, how to prepare, and where to get support.
Why breast screening is important
Breast cancer is the most common cancer in women in the UK. However, early detection greatly improves outcomes and increases treatment options.
Screening can:
- Detect cancer before symptoms develop
- Increase the range of treatment options available
- Improve survival rates
- Reduce the need for more complex treatment
Even if you feel well, it is important to attend screening when invited. Screening can detect changes long before you notice symptoms.
Who is eligible for NHS breast screening in Essex?
The NHS Breast Screening Programme offers free screening every three years to:
- Women aged 50 to 70
- People aged 50 to 70 who are registered as female with a GP
You may receive your first invitation between the ages of 52 and 53, depending on when you enter the screening cycle.
If you are aged 71 or over, you will not automatically receive invitations. However, you can request screening by contacting your local breast screening service.
If you believe you should have received an invitation but have not, contact your local screening service first. If needed, your GP practice can also help.
What is a mammogram?
A mammogram is a special X-ray that checks for early signs of breast cancer. It can detect small changes in breast tissue that you cannot see or feel.
The mammographer will take images of each breast from different angles. These images help specialists identify any changes that may need further investigation.
Attending your appointment
You will receive a letter with your appointment date, time, and location. Most people attend a mobile screening unit located near their home. However, screening may also take place in a hospital or clinic.
If the appointment is not suitable, contact the screening office as soon as possible to rearrange it.
Please contact the screening team in advance if you:
- Have mobility or accessibility needs
- Require additional support
- Would like a chaperone
- Have cultural or religious requirements
The screening team will arrange reasonable adjustments to support your needs and help you feel comfortable.
What happens during your mammogram
When you arrive, the reception team will welcome you and guide you to a private waiting area. A trained female mammographer will then call you and explain the procedure clearly.
You will have privacy to undress from the waist up.
During the mammogram:
- The mammographer places each breast between two flat plates
- The plates gently compress the breast for a few seconds
- The mammographer takes images from different angles
- The procedure screens both breasts
You may feel some pressure or brief discomfort. However, this only lasts a few seconds.
The mammogram itself usually takes five to six minutes. The full appointment normally lasts around 20 minutes.
Throughout the appointment, the mammographer will support you and answer any questions.
Getting your breast screening results
The screening service will send your results by post, usually within two weeks. Your GP will also receive a copy.
Most people receive a normal result. However, screening sometimes identifies changes that need further checks.
If this happens, the screening team will invite you for additional tests within three weeks. This does not necessarily mean you have cancer. In fact, most people who attend further tests do not receive a cancer diagnosis.

Checking your breasts between screenings
Screening does not replace being aware of your own body. It is important to know what is normal for you.
Contact your GP as soon as possible if you notice:
- A new lump or thickening
- Changes in breast size or shape
- Skin dimpling or puckering
- Nipple changes or discharge
- Persistent or unusual breast pain
Do not wait for your next screening appointment if you notice changes. Early assessment provides reassurance or allows treatment to begin promptly if needed.
