Experts recommend mammograms starting at age 40. How frequently and how early to be screened depends on your own individual risk, making it important to see a health care professional to determine your risk and when to begin screenings. In the meantime, everyone should be aware of any changing symptoms in their breasts.

\"It's also important to be aware of one's body and notice any changes, pointing them out to one's doctor if they arise,\" Mayer said.

Finally, experts say that it is very important to know your family history, which could influence your own risk of breast cancer. \"For a long time, cancer was taboo, and people didn't talk about cancer,\" said Lee. \"But your family history is important, because again, that could put you at higher risk.\"

Triple-negative breast cancer is becoming more treatable as more discoveries are being made, giving hope to experts and those living with the disease.

\"I meet people every day and they think it's the end that we don't have treatment, that we can't help them and as an oncologist, that's not the case,\" said Lee. \"There is hope.\"
