Hi thanks for contacting HCM... Let me solve your query... If throat cancer present then in late stage tumour cell can circulate in blood that can be identified in CBC .... But until then CBC will be normal... Here your condition could be smoking related esophagitis or gastritis.... So for that take omeprazole on empty stomach for reducing acidity.... Avoid excess spicy foods ..... More fruits taken.... Get your throat examined ... If any mass revealed after examination take biopsy and send it for histopathological examination..to reveal nature of mass whether neoplastic or not.... You have to stop smoking as smoking can affect multiple organs and morbidity high... Consult physician for examination and accordingly investigation... Let s see also what is your CT report which is best investigation... Take care ...
