Aromatase inhibitors (AI) are medications that block production of estrogen, the hormone that feeds most breast cancers.

Breast cancer in older women behaves differently than it does in younger women. Breast cancer is less likely to return in older women. So older women can be treated differently, too, a new study suggests.

What age should breast cancer screening start? How often should it be performed? How many women have to be screened to prevent one breast cancer death? Breast cancer screening is controversial.

Once cancer spreads, controlling it becomes a much more complex challenge. Researchers looked at the survival benefits of treatment alternatives for advanced breast cancer.

About one in five women diagnosed with breast cancer have too much of a protein called HER2, which makes the cancer more likely to grow faster and return. New research has some good news for women with this cancer.

HER2-positive breast cancer is an aggressive disease that thankfully can be treated with targeted therapies. A new combination regimen was successful in keeping patients in a recent trial disease free.

Women having a mastectomy to treat breast cancer can opt to have immediate reconstruction. These surgeries use implants to reconstruct breast tissue that was removed during the mastectomy.

In 2009, the US Preventive Services Task Force (USPSTF) recommended that women between the ages of 50 and 74 have breast cancer screenings every two years. A new study has challenged these guidelines.

The gold standard for breast cancer screening is digital mammography. Unfortunately, false-positives, which appear to be breast cancer but turn out not to be, are not all that unusual for mammography.

If a woman’s close relative is known to carry a BRCA gene mutation, she will want to see if she is also a carrier. If this woman learned that she didn’t have an altered BRCA gene, that might offer some relief.
