Bill Posted October 5, 2004 Share Posted October 5, 2004 Has anybody ever been told anything by their oncologists regarding the accuracy of tumor measurements ? When I voiced concern to my wife's rad onc that the primary tumor in her left lung had grown from 2.0 cm. to ~ 2.5 cm. ( based on her last 2 chest CT scan reports ) he said not to place much importance on a 0.5 cm. change. He said that several factors can cause a tumor's measurement to vary from one scan to the next whether there's been any actual change in size or not. He mentioned such things as the view ( or slice ) that the radiologist looks at and measures as well positioning and stretching, etc. in the tumor area during the scan. BTW, he also said that it's not unusual for scans and / or radiologists to miss very small lung nodules. Quote Link to comment Share on other sites More sharing options...
