While cancer has almost become one among the lifestyle diseases today, advances in treatment have ensured a growing number of survivors. But, are these survivors living a healthy life going ahead?

Despite this, the overall five-year survival rates for most cancers have improved -- sometimes significantly -- since 2000, a study published last week in journal The Lancet revealed.
