In very old mice, two drugs that clear out "zombie cells", damaged cells that stop dividing but don't die, made the typical mouse live 36% longer after treatment began.
In people, the first trials are small and results are mixed.
Here's what we know.
As of 19 October 2026, no senolytic is approved to treat ageing. Dasatinib's US label covers only certain leukaemias.
A US trial registry text search for "senolytic" lists 19 studies planned or under way, a few not testing drugs.

Women with breast cancer had used antiperspirant or deodorant no more often than women without, in a 2024 review of 7 studies. All 7 relied on women's memories.
A small 2017 study that disagrees found its link in 18 women with cancer and 9 without.
Here's the breakdown: (1/12)
Our read: the evidence does not support the myth. No study can prove zero risk, and the studies of product use here relied on women recalling past habits.
This is research, not medical advice. If you are worried about your breast cancer risk, talk with your doctor.
