Common cancers linked to CT radiation include lung, colon, leukemia, and bladder cancer;</p><p class="ql-block"><br></p><p class="ql-block"> in women, breast cancer was also significant. It is essential to avoid unnecessary scans. A previous investigation has found that up to one-third of CT scans may be unnecessary. </p><p class="ql-block"><br></p><p class="ql-block">April 2025</p><p class="ql-block">https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2832778</p>
