How is cancer mutation treated?
One way this is done is by using a drug to target a specific genetic change (also referred to as a mutation) in the cancer cells that is not seen in healthy cells. Historically, many of these mutations have been associated with an aggressive biology and sometimes resistance to cancer treatments, such as chemotherapy.

What are the treatment options of breast cancer patients with BRCA1 mutation?
Compared with sporadic breast cancer, their prognosis is still debated. Treatments of BRCA1/BRCA2 pathogenic variant breast cancer are similar to those for BRCA-negative breast cancer, mainly including surgery, radiotherapy, and chemotherapy.
What are the latest breast cancer treatments?
Palbociclib (Ibrance), ribociclib (Kisqali), and everolimus (Afinitor) have all been approved by the FDA recently for use with hormone therapy for treatment of advanced or metastatic breast cancer.
What does ATM mutation mean?
While an ATM mutation means you have a somewhat higher risk of developing cancer than the average person , it may not fully explain why your blood relatives has cancer. As we learn more about these mutations, we may learn they increase the risk for other types of cancers.

What does the ATM gene do?
They are not related to you through marriage or adoption. Your ATM gene normally helps prevent cancers. A mutation in this gene causes it to stop working like it should. This increases your risk for certain types of cancers.

What happens if you have a mutation?

What is the risk of breast cancer if you have an ATM mutation?
It has been suggested that women who carry a mutation in the ATM gene have an estimated 20-60% increased risk for breast cancer (Renwick et al Nature Genetics. 2006; 38 (8):873-875). Those with an ATM gene mutation are thought to be at increased risk for early-onset breast cancer and bilateral breast cancer. However, the exact breast cancer risk, and whether or not there is any other cancer risk, conferred by a carrying a mutation in the ATM has not been determined. Some studies have also suggested a possible increased risk of sensitivity to radiation (Broeks et al Breast Cancer Res Treat. 2008; 107:243–248). Research in this area is ongoing and our understanding of the implications of carrying a single ATM mutation may change in the future. It is important for patients to keep in contact with their doctors and genetics providers for updates in this area.
