21 Jul Low-dose Aspirin Linked To Lower Breast Cancer Risk
There is great news for those who take a low dose of aspirin regularly. According to a new study released in the Breast Cancer Research journal, a study of over 57,000 women showed that taking a low dose of aspirin reduces the risk of having breast cancer.
Among the 23% of women that took a low-dose of aspirin regularly, researchers observed that the risk of having HER2 negative/HR positive breast cancer (the most common type of the disease) was lowered by 20%.
Women who took a high dose of aspirin or anti-inflammatory medications like ibuprofen did not exhibit any major difference. Earlier studies showed mixed results in a reduction of breast cancer risk for women who consumed a high dose of aspirin regularly.
Aspirin is well known for its capacity to lower other types of cancer and cancer-related deaths, especially in those at risk of having colorectal cancer. The guidelines of the US task force on preventive services, suggests that some people take a low dose of aspirin every week to cut down on the risk of colorectal cancer and cardiovascular disease. But this option is not safe for everyone. For instance, people with diseases like ulcers, Crohn’s and other bleeding ailments should avoid it because it tends to increase bleeding.
This new study did not focus on the exact reasons why aspirin can lower the risk of breast cancer. But a significant reason for this may be the ability of aspirin to reduce inflammation. A low dose of aspirin can reduce symptoms like inflammatory conditions and obesity which are risk factors for breast cancer.
Research has revealed that aspirin serves as an aromatase inhibitor. Physicians usually treat breast cancer with drugs that work as aromatase inhibitors. This prevents the secretion of estrogen that stimulates the spread of breast cancer cells. For now, more clinical trials are required to be sure that there is a strong connection between the inhibitor effect of aspirin and the reduction of the risk of having breast cancer.
A study conducted in 2013 at Harvard University showed that there was a decrease in colorectal cancer within a 10-year period of using low-dose aspirin. But the study was silent on the link between low dose aspirin and breast cancer.
With the findings of this new study, you may want to add a low dose of aspirin to your daily routine. But before you do so, remember that the results of the study were merely observational. This indicates that it cannot be used to ascertain the actual cause and effect.
All the meta-analyses cited by the authors of the study are based on the same observational data. But large observational studies, like this one, can help to reveal defect effects in certain groups or to detect some very rare outcomes that clinical trials will not be able to detect. That is why these type of studies are very valuable.
