For years, postmenopausal breast cancer survivors have been treated with medications that block estrogen production to reduce the risk of cancer returning. One medication may also prevent the disease from developing at all.

A medication that treats a type of leukemia targets a protein that’s involved in the spread of breast cancer. Combining this medication with a standard breast cancer therapy helped some patients live longer.

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.

Myelofibrosis is a type of chronic leukemia that attacks bone marrow. Researchers at Mayo Clinic showed promising study results for one treatment for this disease.

A medication taken off the market in 2010 may have a new use in treating children with an aggressive form of blood cancer.
