  • May 13, 2014

At first glance, the connection between a cancer diagnosis and depression might seem to be an obvious one. However, in patients battling this life-threatening disease, depression can have a serious impact, and even worsen the odds of survival. While the best approach to interrupting this vicious cycle is not fully understood, clinicians can help patients improve their odds by availing them of therapeutic resources and open communication.

HemOnc Today presents 10 “fast facts” about the correlation between depression and cancer.

5. A combination of shortened telomeres and depressive symptoms is associated with a threefold increased mortality in patients with bladder cancer.

In a study published in 2012, researchers found a correlation between the combination of depression and shortened telomeres length caused a threefold increase in bladder cancer mortality. Depression was also independently linked to bladder cancer in these patients. Read more
