The outlook for your friend is not good.
I will reiterate ,STATISTICALLY someone who has developed bone secondaries from breast cancer has a 50% chance of living ONE year.....but a 50% chance of living longer than one year. Survival rates usually with cancers are usually calculated over 5 years, but the prognosis is so bad with bone secondaries from breast cancer that so few survive 5 years(if any)that survival rates are just not justifiable or meaningful for more than a year,
BUT these are statistics and in Medicine it is quite common that human response doesn't comply with statistics, humans,with their problems are individuals.
That is why it twists my guts to see questions answered on Body and Soul with a bloody website link.
I hope that this has helped you to understand your friends situation.
