Breast Screening: frequently asked questions

Here is a selection of the most common questions GPs and their patients have about breast screening.

Can members of the Primary Care Team visit OBIC?

We believe it would be very useful to women for you to have seen the mammography and assessment procedures at first hand.

We are very keen for doctors and staff who have not seen mammography in action, or who would like to attend the assessment clinic, to contact us to arrange a visit.

Who is eligible for Breast Screening?

All women aged between 50 and 71 years of age are eligible for screening.

How will a woman be invited for screening?

The invitation for screening will be sent to the woman from the OBIC screening office.

The invitation letter will offer a specific appointment time together with clear instructions on how to re-arrange the appointment if necessary.

The invitation letter will include a leaflet explaining what Breast Screening is all about.

What about symptomatic women?

The NHS Breast Screening programme is a service for well women.

Women of any age who present with a breast problem should be referred to the Symptomatic Breast Clinic at the Churchill Hospital via the specialist breast surgeons.

What happens to women who don't attend?

All non-attendees are sent a letter offering them the opportunity to make another appointment.

Practices receive notification of all non-attendees. GPs, Practice Nurses and Health Visitors are in an ideal position to discuss breast screening when the woman next attends the practice.

If non-attendees wish to be screened they can contact OBIC to book a screening appointment.

What are the possible results of the initial screening test?

All mammograms will be classified as either 'normal' or 'abnormal'.

Some mammograms may need to be repeated for technical reasons before being classified.

What happens if the result is 'normal'?

A woman with 'normal' results will be informed by letter within three weeks of her screening.

She will be re-invited for screening in three years providing she is still eligible.

GP practices will be notified of all 'normal' results by the screening office.

What happens if the result is 'abnormal'?

If some abnormality is detected the woman will be invited to attend the assessment clinic within two weeks of the initial screening.

The appointment will be made for a date as soon as possible, in order to minimise the potential for anxiety.

GP practices will be notified of all women called for assessment.

GPs will be informed of the results for all women attending for assessment.

What about women with disabilities?

The mobile unit is entered by a set of steps. If a woman is likely to have difficulty managing these, an appointment can be made for screening at the Churchill Hospital, at a special clinic where help is available.

Such hospital-based screening appointments are available for any women who would prefer to come to the Churchill Hospital at Oxford rather than be screened on the mobile unit in their locality. They will need to arrange this by telephoning the OBIC office on receipt of their invitation.

What about women who have breast implants?

Women who have had reconstruction implants following complete mastectomy do not require mammography. If a woman has one reconstruction implant that side does not need mammography, but the other breast should be screened in the usual way.

Women who have cosmetic breast implants are able to come for screening. Further information will be given to them at their appointment. If you are invited for screening and have implants, please call the office to let them know.

What if a woman has had breast cancer?

A woman who has had breast cancer prior to the screening invitation can attend for her screening appointment, if she has not had a mammogram within the last six months anywhere else. Women who are under care for breast cancer and are having follow-up mammograms will be called annually and should cancel if offered a routine breast screening to keep with their annual mammograms. Women with any questions or concerns about this should telephone the OBIC office for a confidential discussion.

What if a woman has a family history of breast cancer?

A woman with a family history of breast cancer is advised to contact her GP who can discuss referring her to a genetics clinic.

Does taking HRT change the screening procedure?

Taking HRT does not at present require additional screening.

What if a woman experiences difficulty with compression during mammography?

The mammography process requires that each breast is compressed between plastic plates for a few seconds while the X-ray is being taken. This procedure is explained to women by the radiographer. Some women find the procedure uncomfortable although most women find the pressure acceptable.

A woman who is unable to tolerate the compression can request the examination to be terminated at any time. In this case, she will have the necessity for the compression explained again and the decision to proceed is hers. An ultrasound examination instead of mammography is not a technically viable option.

Is there any danger in having a dose of radiation every three years?

Radiography of all kinds offers a theoretical risk, which needs to be balanced against the positive effects of the procedure. Mammography uses low-dose radiation in which the risk is minimal.

The Royal College of Radiologists provide the following statement:

"The risk of radiation-induced breast cancer as a result of mammography is mainly theoretical and is so small as to be negligible when compared with proven benefits of early detection of the disease. At worst the risk of developing breast cancer as a result of undergoing mammography has been calculated as one chance in a million."

Since the radiation risk is age-related, the risk from mammography for women aged 35 years and over is considerably lower and approaches zero.
