The difference between nodules and tumors

Nodules are terms mentioned in many imaging reports, such as breast nodules and lung nodules, which may be benign or malignant. If benign, they can also be called benign tumors. If malignant, they are usually malignant tumors, which we call cancer. Therefore, nodules and tumors are actually two different terms, nodules are a descriptive language, tumor is a pathological description language, nodules alone can not determine the nature, need to do further pathological examination, can judge which type of nodules. The above health science knowledge is for reference only, the specific situation needs to go to the regular hospital examination, by professional doctors to judge.
