A recent study published in the International Journal of Cancer, showed that, irrespective of the beta-blocker type, there was no protective effect of beta-blocker use on the risk of contralateral breast cancer (CBC) among women.
Beta blockers are a class of drugs that are used to treat blood pressure. Some laboratory studies have shown that these drugs can kill normal as well as malignant cells. But this outcome has not been shown in case of contralateral breast cancer (tumour in the opposite breast diagnosed more than 6 months after the detection of the first cancer).
The study included 52,723 women with breast cancer using beta-blocker. The risk of contralateral breast cancer was estimated.
The results showed that, out of 1444 women with CBC, 209 were using beta-blockers.
Hence, women with breast cancer did not experience any protective effect of beta-blockers. Overall findings did not suggest beta-blocker use as protective against the risk of CBC, irrespective of beta-blocker type.
