Had a lot of chest xrays over the course of 2-3 years. probably about 10 or so. was in the er a lot for chest pain. im scared of my cancer risk. what is my risk?

Health Harvard says: "simple chest x-ray (3o views) exposes a person to an average of 0.01 mSv, or roughly the amount of radiation you get in a day from the natural background." "American College of Radiology recommends limiting lifetime diagnostic radiation exposure to 100 mSv. That is equal to 10,000 chest x-rays " REF: https://www.health.harvard.edu/staying-healthy/should-i-worry-about-x-rays. Dr. Komaroff
