Mammography » Regular Mammograms
A Mammogram is a special breast X-ray which shows the glands, fat and blood vessels of the breast. There are two reasons for having a mammogram, Screening and as part of Diagnostic Breast Imaging.
Screening means looking for possible breast cancer when you have no signs or symptoms of breast disease.
Mammography can detect tiny changes in your breasts which you may not have noticed. These changes may be due to cancer and may be smaller than a grain of rice. 90% of breast cancers are detected by mammography. Early detection and treatment of small cancers greatly increases your chances of cure.
The benefits of screening mammography have been proven in large international trials.
Yearly mammography is recommended for women 40-50 years of age. Women over the age of 50 years should have screening mammography every two years.
It may be appropriate that women with a family history of breast cancer start mammography at an eariler age, or have annual mammography.
Diagnostic Breast Imaging means looking at something in your breast that is worrying you or your doctor.
Most of these changes will not be due to cancer, but you should see your doctor as soon as possible to arrange the necessary tests.
This type of mammogram can be done at any age but ultrasound may be performed first in women under thirty five yeas of age
Even through your mammogram is normal your doctor may send you for further tests e.g. biopsy or aspiration. If appropriate, this is arranged at the same visit.
The X-ray process involves some exposure to radiation, however with modern equipment your exposure is very low. The benefits of finding and treating a breast cancer early far outweighs any risk for the X-ray itself.
You will be asked to undress from the waist up. Please wear a skirt of trousers if possible.
Each breast is examined separately. A female radiographer (a technologist who is an expert in the use of x-ray equipment) will palpate your breast then carefully position your breasts on the X-ray machine. This has compression plates that flatten the breast tissue allowing the best images to be taken. You stand for the X-rays which only take a few minutes.
The test may be uncomfortable, but is usually not painful.
Usually two views of each breast are taken - one looking from above and the other from the side. Sometimes further X-rays are needed to show an area of the breast more clearly.
Don't be concerned if this occurs. Ultrasound may also be necessary to complete your examination. For this a small amount of warmed gel is placed on your breast and a probe is held against the skin. This is very similar to a pregnancy ultrasound examination and is painless and safe. Ultrasound is particularly useful in detecting cysts and evaluating breast lumps in younger women.
