Chemotherapy to treat breast cancer may accelerate biological aging
The Independent • • health
Key Points:
- New research from Georgetown University suggests that aggressive chemotherapy for breast cancer may accelerate aging, potentially reducing healthy life expectancy by over nine years.
- Chemotherapy-induced aging is linked to an increase in senescent cells, which contribute to tissue damage and inflammation, raising the risk of aging-related diseases and early death.
- The study analyzed data from 400 million women and found a correlation between chemotherapy and elevated levels of the protein p16, a marker of cellular aging, indicating potential targets for extending survivors' lifespans.
- Researchers are exploring interventions such as increased exercise and repurposed medications to mitigate chemotherapy's aging effects and improve long-term health outcomes for breast cancer survivors.
- Breast cancer survivors represent the largest group of cancer survivors in the U.S., with numbers expected to rise significantly, underscoring the importance of addressing treatment-related aging alongside cancer care.
