Chemotherapy to treat breast cancer may accelerate biological aging
Yahoo • • health
Key Points:
- New research from Georgetown University's Lombardi Comprehensive Cancer Center suggests that aggressive chemotherapy for breast cancer may accelerate aging and reduce healthy lifespan by over nine years.
- Chemotherapy increases the number of senescent cells, which contribute to tissue damage and inflammation, potentially leading to aging-related diseases later in life.
- The study analyzed data from 400 million women and linked chemotherapy to elevated levels of the protein p16, a marker of cellular aging, with potential to target this pathway to improve survivor longevity.
- Researchers are exploring interventions such as increased exercise and repurposed medications to counteract chemotherapy-induced aging 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, prompting further research into aging effects from other treatments like radiotherapy and immunotherapies.
