Aspirin has an anticancer effect, a new study confirms.
Latest from this study showed that after successful treatment for breast cancer, women are significantly aspirin regularly have a lower risk of death from recurrent cancer. Aspirin also reduces the risk of having their cancer spread to other sites.
What does this mean for the people being treated for cancer? What does it mean for people worried about their cancer risk? Here are answers to this and frequently asked questions about aspirin and cancer.
Does aspirin really improve breast cancer survival?
Only clinical trials, where treatments are randomly tested against an inactive placebo, could prove that the treatment is truly effective.
Until evidence is available, the next best thing is a study in which people taking the treatment were observed from time to time. Nurses Health Study followed more than 4,000 nurses who have been treated for breast cancer at least 12 months earlier.
The result: Nurses who took aspirin significantly less likely to die from breast cancer and the cancer has relapsed at another site. After adjusting for stage of cancer, menopausal status, body mass, and hormone sensitivity of tumors, women who took aspirin seven days a week were 43% more likely to die from breast cancer.
The findings may apply only to women who survive at least four years after breast cancer treatment. But because 90% of women diagnosed with breast cancer survive at least five years, "our findings have important clinical enough," the researchers concluded Michelle D. Holmes, MD, DrPH, and colleagues at Boston's Brigham & Women's Hospital. Their study was published online in the Journal of Clinical Oncology.
Aspirin treatment could replace the other breast cancer?
No. If aspirin really help prevent breast cancer recurrence, it was only when combined with cancer therapy is recommended.
Aspirin can prevent breast cancer?
Several studies have shown that aspirin can reduce the risk of breast cancer in women who do not have the disease. Other studies reached the opposite conclusion.
When data from several studies are combined, there is evidence that aspirin or non-steroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen) can slightly reduce the risk of breast cancer.
Most women do not get breast cancer. Take aspirin every day for a long time risk, especially risk of stomach or intestinal bleeding. This means that for most women, the risk of taking aspirin may exceed the benefits of preventing breast cancer.
However, when taken under medical supervision, routine low-dose aspirin use does not reduce the risk of heart disease. It's not clear whether the women at higher risk of breast cancer may be an additional benefit of aspirin.
Aspirin can prevent other types of cancer?
Aspirin can be sold on the table, but it was a very powerful drug. This has at least two effects that, in animal studies, the fight against cancer.
Aspirin is the most studied in colon cancer. Human studies strongly suggest that aspirin increases survival in patients treated for colon cancer. The study also showed that aspirin lowers the risk of new polyps in patients who had precancerous colon polyps removed, and that regular use of aspirin lowers the risk of colon cancer.
However, the U.S. preventive services recommended against the widespread use of aspirin to prevent colon cancer. Once again, the risk of aspirin is greater than the benefits to the people in the normal risk of colon cancer.
Aspirin also may reduce the risk of other cancers, especially prostate cancer and esophagus cancer.
As with breast and colon cancer, the most powerful benefits seen in patients who are treated for cancer. Although there is evidence that aspirin has a broad anticancer effects, there is no strong evidence that these benefits - even when combined with the benefits of low-dose aspirin in preventing heart disease - beyond the normal risk for people at risk of cancer.
