Whats prognosis secondary cancer bones lungs and liver?

It depends on the type of the primary malignancy. For instance small cell lung cancers grow more rapidly than non-small cell lung cancers. Melanomas, breast cancers, renal cancers, and many others have variable prognoses when metastatic to multiple site such as lungs, bones, and liver.

With liver mets you are often looking at less than six months - BUT - predictions are averages with a large variation from person to person and varying with many other factors: type of malignancy, whether the person has a cancer that is responsive to systemic treatment such as chemotherapy or hormonal therapy, the general health and age of the person, the tumor burden - meaning how large the metastatic lesions are in the vital organs (lungs & liver), plus other co-morbid conditions, etc.

Doctors can never predict one person's survival time months in advance with perfect accuracy. People often say things like "My doctor gave me X number of months, and I'm still here." Doctors do not "give" the amount of time. When we are pushed to make guesses, they are averages. If a doctor says six months, it may be three months or a year. There is no way to predict the future. Unexpected things come up such as infections (pneumonia especially), bleeding episodes, blood clots, strokes, and others.

Secondary, metastatic, or a spread of the primary cancer to any organ has a very bad prognosis.

Lungs and liver are one of the most common organs of the body to accept secondary cancers.

Just how bad the prognosis is, depends upon several factors, such as, where the primary cancer was, the age of the patient, the degree of spread, etc.
