Overview
- Clinicians say about 98% of cancers found at the earliest stage are curable, urging prompt evaluation of any new change.
- Most women at average risk are advised to begin routine mammograms around age 40; those with a family history may start earlier and may need ultrasound or MRI.
- People with BRCA1 or BRCA2 risk are recommended to begin surveillance as early as 25 with breast MRI following genetic assessment.
- Experts outline monthly self-checks—two weeks after a period, use the flat of three middle fingers in circular motions, inspect in a mirror, and include the armpit and collarbone areas.
- Watch for warning signs such as a new lump, skin dimpling, nipple inversion or discharge, swelling under the arm, or a sudden change in size or shape, and seek medical advice.
