my friend 'did x ray on the lumbar&sacral vertebrae then she discovered she is 12 days pregnant,,,is there any risk on the fetus?what's ur advice?

X-rays during pregnancy don't increase the risk of miscarriage or cause problems in the unborn baby, such as birth defects and physical or mental development problems.

However, if a pregnant woman has an X-ray and is exposed to radiation there is a very small increased risk that the baby may go on to develop cancer in childhood. This is why the dose of radiation used in an X-ray is always as low as possible.

Can I have an X-ray if I'm pregnant?
