Taking Control of Your Risk for Breast Cancer:
Taking control of your risk for breast cancer is an empowering journey guided by actionable steps tailored to your unique situation. Imagine being able to shape your health destiny, making strategic lifestyle choices that act as a powerful defense. These lifestyle choices range from eating a healthy diet to exercising daily or breastfeeding your children.
Women with a lifetime risk exceeding 20% may benefit from annual breast MRI screens in addition to mammograms. Some guidelines even propose initiating this screening as early as 30 for those at elevated risk. At this risk level, women can also request two clinical breast exams, and all women should get to know how their breast typically feels so that they can report any changes if they occur.
Regular screenings and monitoring strategies further enhance your defense. Biannual check-ups and multiple imaging strategies protect your health, detecting any potential issues early. But for those with heightened risk, the proactive addition of annual breast MRI scans becomes a game-changer in early detection as it can detect some lesions that mammograms may miss (and vice versa).
Proactive health decisions become even more crucial. Armed with risk information, discussions with your healthcare team may include risk-reducing medications such as tamoxifen or raloxifene. These medications come into play when your 5-year breast cancer risk is estimated at 1.7% or higher, offering an additional layer of protection in your personalized health plan. It's not just about understanding your risk; it's about actively managing it, making informed decisions, and becoming the hero of your own story.
