Hi mohini Thanks for coming to HCM lung cancer needs usually smoking one pack of ciggarette per dau for 40years ( 40 pack years) to manifest. I am just not saying that yours smoking habit is a good one and you should continue till 40 yrs /......its just to alleviate your concern....you must quit as aoon as possible. enlarged fatty liver is usually due to drinking alcohol....if you have probably concealed your drinking habbit here just give it up. your symptoms of cold or rhinitis is for last one month that can be dut to nasal structural abnormality like deviated nasal septum, or via alergic rhinitis....so just take ENT opinion and accordingly they may prescribe nasal steroid spray and antihistaminics.... Chest pain has various reasons...apart from infection can be musculoskeletal, can be due to acid reflux, can be due to acute pleuritis, anginal pain etc since the chest xray is normal and there is no sympton except for pain you can try analgesisc with muscle relaxant and proton pump inhibitor.... best wishes
