Can pet scan always diagnose /confirm presence of lung cancer or can only give indication and later biopsy is vital to confirm cancer if a nodule seen?
Bx definitive: A positron emission tomography (pet) scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body. It is often used to determine the treatment of cancer, if it is spreading, or improving, etc. Used in combination with tests such as ct or mri, it can provide a very high index of suspicion for cancer, but a bx is always definitive and used for tx. ...Read moreGet help now ›
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

Tumor spread: Cancers can spread to different areas in the body. It is not uncommon for lung cancer to spread beyond the lung to other areas such as the liver and bone. If you have a known lung cancer and an abnormality in the liver it may be spread of the lung cancer. Certain tests like an MRI may be helpful to see if it is an often seen benign lesion (hemangioma). If it can't you may need a biopsy. ...Read moreGet help now ›
Can you have adeno and squamous lung cancer at the same time? What is the significance for treatment? 2 biopsies --- one from main lung mass showing squamous, one from lymph node showing adeno.
Yes...: It is possible that there are two different cancers. It may also be that the primary tumor is a combination of the two (adenosquamous) and the biopsy only sampled one part. Adenosquamous tumors contain adenocarcinoma and squamous cell carcinoma. And either or both types of cancer may spread to lymph nodes. ...Read moreGet help now ›
