Breast cancer--a comparative study between Malaysian and Singaporean women.

Breast cancer is the leading cause of cancer deaths in Malaysian and Singaporean women. A study done to compare the epidemiology of the disease, as well as to compare the rate of conservative surgery between Malaysian and Singaporean women was carried out. The results show that the median age at presentation was the same in both countries, and the incidence was lower among the Malays. However, there was a significant difference in the stage at presentation and the tumour size; Singaporean women presented at earlier stages and with smaller tumours compared to Malaysian women. This led to a lower rate of conservation surgery in Malaysian women.
