What to Know About Mirena and Breast Cancer
Mirena (levonorgestrel-releasing intrauterine system) is a hormonal intrauterine device (IUD) used for contraception. It is effective at preventing pregnancy by releasing a small amount of progestin (levonorgestrel) into the uterus.
Mirena has been studied for its potential link to breast cancer. Some studies have suggested that Mirena may be associated with an increased risk of breast cancer, while others have found no significant link.
Overall, the evidence on the link between Mirena and breast cancer is mixed. More research is needed to determine whether Mirena actually increases the risk of breast cancer.
If you're considering getting a Mirena IUD, you should talk to your doctor about the potential risks and benefits. Your doctor can help you decide if Mirena is the right choice for you.
Here are some additional things to know about Mirena and breast cancer:
- The most common type of breast cancer associated with Mirena is ductal carcinoma in situ (DCIS). DCIS is a non-invasive form of breast cancer that can develop into invasive breast cancer if left untreated.
- Mirena has also been linked to an increased risk of invasive breast cancer, but the risk is small.
- The risk of breast cancer associated with Mirena is thought to be related to the progestin in the IUD. Progestins are similar to the hormone estrogen, which is known to promote the growth of breast cancer cells.
- The risk of breast cancer associated with Mirena appears to be highest in women who are using the IUD for a long period of time.
- Mirena does not appear to increase the risk of breast cancer in women who have a history of the disease.
- If you're concerned about the potential link between Mirena and breast cancer, talk to your doctor. They can help you decide if the Mirena IUD is right for you.
In summary, the evidence on the link between Mirena and breast cancer is mixed. More research is needed to determine whether Mirena actually increases the risk of breast cancer. If you're considering getting a Mirena IUD, you should talk to your doctor about the potential risks and benefits.
