Some databases helps you look up an article cited or used by a selected article. This is the concept of citation searching -- from a key article, search to see when and where it has been used.
For example
Jemal, A., Murray, T., Samuels, A., Ghafoor, A., Ward, E., & Thun, M. J. (2003). Cancer statistics, 2003. CA: a cancer journal for clinicians, 53(1), 5-26. Since 2003, it has been cited 18,184 times at least, including 241 times already in mid-2018.

If you want to check the accuracy, look at the article's references and the reliability of the journal (that contains the article, which is not covered here):
