WEDNESDAY, June 2 (HealthDay News) -- The painkiller a woman
takes after a mastectomy may influence the odds of breast cancer
recurrence, a new study suggests.
Researchers at the Catholic University of Louvain (Leuven) in
Belgium looked for links between painkiller use and breast cancer
recurrence in 327 women from one to four years after they underwent
Women who received a powerful prescription painkiller called
ketorolac (sold as Toradol and Acular) which is related to aspirin
and ibuprofen, were less likely to develop a recurrence of breast
cancer. Their rate was 6 percent compared to 17 percent for those
who received other drugs for pain.
The link between the drug and lower rate of recurrence remained
even after the researchers adjusted for factors such as patient age
and stage of cancer.
The study, published in the June issue of the journal
Anesthesia & Analgesia, adds to a growing body of literature that indicates pain-relieving drugs can affect cancer.
