The harm of CT on the human body is mainly the radiation effect of CT on the human body, because CT utilizes radiation to conduct tomography on the body, in the process of scanning more or less will produce a certain radiation effect on the human body. Women, as a special group, are more sensitive to the hazards of CT. The main hazard of CT for women of childbearing age is that they cannot have children within a short period of time, and it is generally recommended to consider preparing for pregnancy only after 3-6 months of CT, which is safer. If you want to have a child too early, you may be affected by radiation, and the fetus may be malformed. Although the probability of this happening is extremely low, it is still safe to consider preparing for pregnancy after 3-6 months, so women who want to have a child in a short period of time should not undergo this test.
