my mom has stage 4 lung cancer and she was in the hospital over the weekend and they did a ct scan that said the tumor on the left side is growing and so is a bilobed nodule in the lower right lung. now my question is what is a bilobed nodule? she has a tumor in the upper right and lower right lobes.also it said something about an enlarging low-attenuation focus in the spleen and a new extrahepatic enlarged lymph node. what does all that mean?
Thanks for your question on Chat Doctor. I can understand your situation and problem. Your mother is having stage 4 lung cancer. Beloved nodule means presence of metastatic nodule in two lobes of lung.  So she is having malignant nodules in both right upper lobe and right lower lobe. Spleen is common site for homogenous spread in lung cancer. So low attenuation lesion in spleen is mostly metastatic lesion. Lung cancer also involve lymphatic system in abdomen. So enlarged extra hepatic node is mostly due to malignant involvement. All these make your mother stage 4 lung cancer patient and treatment for this is chemotherapy and palliative care in the former of pain management and nutrition. Life expectancy in such case is less than 18 months. So consult oncologist and start appropriate treatment.
