I want to share with you the Cochrane 2012 leaflet on mammography, so you can better think about and decide whether to get a screening mammogram or not. It is shocking information. Please discuss the leaflet with your doctor, otherwise he/she may never learn about it.
“Screening for breast cancer with mammography
- What are the benefits and harms of attending a screening programme?
- How many will benefit from being screened, and how many will be harmed?
- What is the scientific evidence for this?
When we first published this leaflet in 2008, the Summary was:
‘It may be reasonable to attend for breast cancer screening with mammography, but it may also be reasonable not to attend, as screening has both benefits and harms.
If 2000 women are screened regularly for 10 years, one will benefit from the screening, as she will avoid dying from breast cancer.
At the same time, 10 healthy women will, as a consequence, become cancer patients and will be treated unnecessarily. These women will have either a part of their breast or the whole breast removed, and they will often receive radiotherapy, and sometimes chemotherapy.
Furthermore, about 200 healthy women will experience a false alarm. The psychological strain until one knows whether or not it was cancer, and even afterwards, can be severe.’
These numbers were derived from the randomised trials of mammography screening. However, since the trials were performed, treatment of breast cancer has improved considerably. More recent studies suggest that mammography screening may no longer be effective in reducing the risk of dying from breast cancer.
Screening produces patients with breast cancer from among healthy women who would never have developed symptoms of breast cancer. Treatment of these healthy women increases their risk of dying, e.g. from heart disease and cancer.
It therefore no longer seems beneficial to attend for breast cancer screening. In fact, by avoiding going to screening, a woman will lower her risk of getting a breast cancer diagnosis. However, despite this, some women might still wish to go to screening.”
