Double primary cancers registered in a tertiary care hospital: review of two cases

In our centre, among 1965 registered cancer patients between May 2011 and December 2013, we report three cases with multiple primary malignant neoplasms. One of them was excluded due to lack of data, and so we present the remaining two cases. The first case is an 82-year-old female patient with colon and thyroid cancer and the second case is a 61-year-old female patient with colon and breast cancer. Both cases were metachronous and discovered accidently during the regular follow up, and managed with a curative intent. Conclusion: It is important for the clinicians to keep in mind that individuals with cancer are at increased risk for subsequent primary malignancies, which must be differentiated from recurrent or metastatic disease.
