Over 6000 women are diagnosed with breast cancer in South Africa each year. Breast cancer is the most prevalent type of cancer amongst Caucasian and Asian women, and the second most prevalent type in Black and Coloured women. With that said, a mammogram – an x-ray exam of the breast used to detect and evaluate breast changes – is the most effective method of detecting breast cancer. However, statistics show a suboptimal adherence to screening mammography. Kathryn Malherbe explains why, and gives us a glimpse of the make-up of a mammographer.
When should you go for a mammogram?
The American College of Radiology (ACR) advises mammography from the age of 40 years. However, if your mother had breast cancer in her forties, then you should have a routine mammogram from age 35.
What does a mammogram procedure entail?
A mammogram procedure, which is done by a mammographer (radiographer that
specialised in the field of mammography) lasts 10 minutes and consists of two x-ray
views per breast.
If there is any area of concern, the radiologist (a physician or doctor who has specialised
in the field of diagnostic radiology) will discuss the possibility of performing a biopsy,
which requires no special preparation and is a fairly minimal invasive procedure. An MRI,
PET or CT scan can also be used to rule out any concerns of the mammogram, but in
most areas this is not widely available and/or cost-effective.
To work as a dedicated mammographer, a special subset of skills is required:
Mammographers play an influential role in the way you, the patient, perceive
mammograms. We also have a complex role to uphold in our profession, necessitating a
high standard of technical competency, good communication skills, and the ability to limit
patient anxiety and discomfort.
Certain personality traits improve this involved task; namely respect, compassion, efficacy
and informed communication. It’s an emotional task; we walk the road with our patients
from the point of initial diagnosis, through treatment regime, recovery and annual surgery
It is sometimes difficult not to feel disheartened when a patient discovers a new malignant
lump after she had been diagnosed and treated for a similar cancer during the past year.
A 2014 study, by the University of Johannesburg, showed that there are four factors
attributed to a mammographer:
Exposing the mammogram myth:
There are numerous myths associated with mammograms; the most common being that
the compression of the breast is very painful, and can cause breast cancer. The latest
digital systems do not require excessive compression of the breast to produce a high
resolution image of the breast. The latest technology has its own internal system
parameters that improve the image quality and resolution for the radiologist. The
compression in itself cannot be associated as a causative factor to produce breast
Cancer is a very elusive disease and there are many factors that contribute to its
development, the most important of which are certain genetic markers that relate to the
initial growth of abnormal cancer cells.
Compression of the breast, or any form of trauma to the breast, has zero potential to be
the singular causative factor of producing cancer of the breast. It is more likely related to
a myriad of factors, more specifically certain mutated genetic markers that cause
abnormal changes within the cells of the breast, that multiply and divide (proliferate) to
form a lump in the breast, which proves to be a malignancy.
It has to be reiterated that the most important factor related to breast cancer is being a
woman and an increase in age. Family history only relates to 5-10% of all breast cancers
