[|Human|] hii my father was diagnosed with GE junction cancer in may,2010. after diagnosis he went thru operation and then six cycles of chemo. on doing PET scan, it was found that cancer has spread to lungs, and near by spleen.and also near the esophagus. but on doing biopsy of the esophagal region, it shows ulcer. i want to know is it possible that inflammation in lungs and other parts are any other thing, not cancer. what is the prognosis in this case.
[|AI|]  Hi, Thanks for writing in. In simple words, cancers cause inflammation, but every inflammation is not a cancer. Inflammation is a process in which there is a response of the immune system in your body to any undesired condition. Inflammation can be due to infection, loss of blood supply, injury, toxicity and cancer. An ulcer is defined as a break in the surface of skin externally or lining membrane of organs internally. Your father might have an ulcer that is inflammatory but not necessary a cancer. The inflammation in lungs can be non-cancerous but for this a FNAC or biopsy must be done and confirmed. In disease that has spread to lungs and near the spleen it is stage 4 cancer and with recommended treatment and supportive care survival can be extended by up to two years. Please do not worry.
