My mother-in-law is diagnosed with lung cancer metastasis to brain and forearm two months back.  She has completed radiation for forearm and brain.  She is vomiting regularly and not eating anything solid just liquids but that too very less.  Last night she vomited dark brown in color and she is very weak and fragile sleeping all the time.  At this time what should i expect.  Is there anything i should worry about?
Hi, dairy have gone through your question. I can understand your concern. She may have hematemesis either due to your cancer, thrombocytopenia or liver disease or GI tract abnormality.  She should go for endoscopy and complete blood count. Then she should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
