Researchers have identified two proteins that predict how long a woman will survive after being diagnosed with ovarian cancer. Experts at MD Anderson Cancer Center say when a woman has high levels of two specific proteins, they live for an average 11 years after being diagnosed with ovarian cancer. Patients with low levels of the proteins live just over 2.5 years. The researchers have evidence these proteins have the same effect in lung and breast cancer patients. Experts say testing patients for these proteins could provide valuable information for treating the disease.
