Erratum to price discrepancy

Previously, when my colleague Jo has given talks about men's health, she's stated that for every $1 spent on prostate cancer, $200 is spent on breast cancer. Recently, she gave a different figure, stating that the prior one was an exaggeration and she found a factual estimated, which is that for ever $1 on PC, it's $1.84 on BC. Slight difference in ratio!
