Breast Cancer Statistics in Malaysia
The importance of addressing this situation has become all the more urgent given that breast cancer has now overtaken lung cancer as the world’s mostly commonly-diagnosed cancer, and is responsible for one in six of all cancer deaths among women, according to statistics released by the International Agency for Research on Cancer (IARC) in December 2020.
The figure above shows the 5-year overall survival rates for women diagnosed in 2007-2011 in UMMC. (Taib NA et al. 2011).
Another study reported a 5-year overall survival rate of 93.6%, 76%, 44%, 9.3% for Stage I, II, III and IV, respectively, in a hospital-based cohort diagnosed between 1995 to 2003 in Malaysia and Singapore.
Malaysia SCAN in 2018 reported 5-year relative survival rates in Malaysia were: 87.5%, 80.7%, 59.7% and 23.3% for Stage I, II,III and IV breast cancer.
The variations are likely due to inconsistencies is the effect of time differences in type of treatments and in staging, as not all patients in government hospitals have access to Ctscans. Furthermore, relative survival is not the same as overall survival.
