<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have received news today that a 2.5 cm nodule was found on the left T2 of my thoracic, my doctor has scheduled an US Thoracic. Just wanting to know my options. Before this I had a MRi brain which found 12 or more white matter in the postventricular region.  <response>: Hi there, It really depends on what the nodule is. Some nodules turn out to be nothing more than scar tissue and others can be cancer. Its impossible to give a prognosis without knowing exactly what it is. A biopsy will usually be able to tell what it is, and further options can be discussed at that time. I hope this answers your question. Please feel free to contact me if you have any further questions.
