<s>[INST] recently I had colonoscopy test and the doctor said that there is a lump in the finding what it can be. I am going for ct scan and surgery next Thursday. the doctor said it may be props or cancerous in stages 1 or 2. is it serious and life treatning, pls advise, I am tensed! I have a sometimes burning sensation in the belly, the stools are sometimes going bits & pieces, dark brown in color and bowels clearing abt 3-4 times a day, sometimes immediately after taking food. I have lost abt 8kgs over a period of 1 year. [/INST] Thanks for asking in healthcaremagic forum   Do not worry, medical science now a days has improved a lot and have solution and cure for many type of malignancies. Your history is suggestive of some growth and your loss of weight may point towards malignancy, but go for follow up and surgery as advised by your doctor. All the best. </s>
