The Main Objective of this research paper is to investigate the accuracy levels of various machine learning algorithms. To find out the accuracy levels of various classifiers we evaluated the various models employed by researchers were listed out and they have few limitations and their drawbacks were listed out. After a systematic literature study, we found out that some classifiers have low accuracy and some are higher accuracy but not reached nearer of 100%. Therefore, we need to employ a more strategic way for the better classification of Lung cancer nodule. Through a systematic literature survey, the low accuracy levels were due to improper dealing of Dicom images. After an extensive study, we found that ensemble classifier was outperformed when compared with the other machine learning algorithms. Thus, by taking consideration of all the classifiers. The findings we drew was that major machine learning algorithms gave accuracy which was not close to 90%. A better model needs to be employed to increase the accuracy level, and need to be revised should be reliable and meaningful draw insights for the tumour diagnosis, so it reflects our better understanding of the classification of lung cancer. And, lastly, intensive research should be done on the field of Oncology for the better classification of benign and malignant tumours.
