The objective of the study was to identify and describe breast cancer survival pattern in Ghana and factors that explain the disparity in survival rates for breast cancer by the use of Cox proportional hazard. The extent to which selected demographic, hormonal and reproductive factors influence the cause of breast cancer were also examined using the logistic regression technique to determine risk of getting the disease. Two thousand three hundred and ninety seven (2397) women were sampled for the study, of which 1022 (42.64%) were diagnosed with breast cancer between the periods 1st January 2002 to 31st December 2008.

Cumulative 5-year survival was 47.91 %. Main mortality risk factors were, tumour size (logrank
