Hello and welcome to HCM, Before answering your query, I would like to give a brief overview of the normal structures present in the right side of the abdomen. The right upper abdomen is the site where liver with gall bladder, lower part of lung with its covering called pleura. The CT scan reveals a mass/ growth in right side of upper abdomen. This mass could be due to enlargement of liver, gall bladder, lung with enlargement of the associated lymph nodes. The upper zone of right lung show area of consolidation or in simple words an area of solidification. Normally lung fields are filled with air but in case of infections, inflammation, tumor the lung tissue becomes solidified or consolidated. The suspicion on the CT scan is that of a malignancy or cancer. In order to confirm or rule out the possibility of cancer, a biopsy is required. Biopsy is a procedure where a small piece of the tissue is taken and examined microscopically. This will help in knowing whether the cancer is present or not. If yes then from which organ is it arising. The treatment of the cancer will depend on the extent of the cancer. It includes surgical removal, chemotherapy and/ or radiotherapy. I hope my answer is of help to you. You need to consult your treating doctor for further management. Thanks and take care. Dr Shailja P Wahal
