X-rays are mostly used in medical profession for imaging and treating cancer. X-rays help doctors view the inside of the body without any cut or operation. X-rays have become an important element in the identification, diagnosis, and treatment of many types of medical disease. With the help of X-ray, the doctor can monitor the progression of a disease and help in its treatment. In X-rays, the level of risk is considered safe for adults but it is not considered safe for pregnant women because X-rays affect the developing fetus. Be sure to tell your doctor before the treatment if you are pregnant. Your doctor may advice a different testing method that does not use radiation (MRI).Radiologist thinks X-rays are the golden gift for science if it should be used in proper way. For improving the quality of the images your doctor will inject you with a contrast dye before some X-rays.
