Does Chemotherapy Make You Old?

Cancer chemotherapy is usually quite toxic. But aside from the known side effects, does it make you age faster?

Researchers looked at several markers of aging, including telomere length, and certain blood markers that seem to increase as we age.

Using breast cancer survivors, they found that those with chemotherapy had markers that suggested they had aged 10-15 years over controls. However, we do not know if this is a long term effect, or whether this will affect total longevity. I hope not.
