No.: By definition, a benign tumor does not metastasize (spread to other sites by invading the blood stream or lymphatic system). Extremely rare cases of 'parasitic' or implanted benign tumors (eg leiomyomas of the uterus) are recognized to occur in sites outside their normal origin, but this is thought to be a result of some form of tissue transplantation, and not true tumor ''metastasis' ...Read more
Are carcinoid tumors carcinoma? Is malignant metastatic stomach carcinoma that's hereditary a carcinoid cancer? carcinoid Neuroendocrine tumors?
Yes: Yes, you bet they can .Not much an MRI can't see. Magnetic Resonance Imaging is one of the most sophisticated and powerful imaging and diagnostic modalities that a radiologist has at his or her disposal. For certain things, CT reconstruction may be better but MRI is an excellent tool. Be more specific for a more specific answer. Do you mean the mediastinum, thorax, or muscles/chest wall? ...Read more
Yes: All tumors arise from normal pre existing cells that have undergone some form of transformation. Several oncogenes are turned on to present the benign as well as malignant lesion with immortality. In the case of the malignant tumor additional changes allow for matrix metalloproteinase to be produced to dissolve walls of blood vessels for metastasis and convert e-cadherin to small e cad. ...Read more

Multilobulated pulmonary mass w/calcifications in left upper lobe. Neoplastic disease vs inflammatory/infectious process. rule out metastatic disease ?
In general...: IN GENERAL, a multilobulated mass is more likely malignant, one with calcifications is less likely. As in much else, size matters, with bigger being more worrisome. If you're smoker, more likely malignant, if from place of endemic TB or histoplasmosis, risk of chronic infection rises. You'll need to be evaluated by a pulmonologist, who will very likely recommend biopsy. ...Read more
No: Benign lung nodules are not rare and are found during routine chest x-rays or, more likely ct scans. The most common are hamartomas or adenomas that are totally innocent if they are in the outer lung as usual but can block a lung if they are in one of the bronchial tubes. Although, pet scans can help determine that these are benign, some require surgical removal to assure that they are benign. ...Read more
Chest x-ray/MRI/PET: There could be blood in the sputum, that is always a cause for concern and gets people motivated. However, pain is usually not a symptom, until later in the process. Seeing your pcp and asking for a chest x-ray is a great place to start! the pcp will help guide you from there. If you suspect something let him/her know, so they can rule that question out, or substantiate your suspicion. ...Read more
Depends: A thymoma is a malignant tumor of the thymus, and the seriousness depends on details in the pathology report. An ectopic thymus and a hamartoma are both benign, but if the report says "thymoma" then it is probably malignant although not necessarily very serious if completely removed. Discuss with your surgeon! ...Read moreSee 1 more doctor answer
Out of the field: Cardiac mr is centered on the heart. You may see on the border of the field partial breast tissue, but cardiac mr is not dedicated to breast. It is not the same exam, no the same protocol. Palpation and mammogram are the best. If something shows on the cardiac mr, then do mammogram. ...Read moreSee 1 more doctor answer
