At what age is mammography typically used to investigate new breast lumps?

Mammography is typically recommended as a screening tool for breast cancer starting at the age of 40, especially for women who are considered to be at average risk. While clinical examinations and ultrasound can be employed for women younger than 40 to investigate new breast lumps, mammography is not routinely used in this age group because breast tissue is often denser, making it more challenging to interpret mammograms accurately.

As women reach the age of 40 and beyond, the risk of developing breast cancer increases, and mammography becomes an essential part of routine breast cancer screening and investigation of any new lumps. Therefore, the correct age for utilizing mammography in this context aligns with the guidelines advocating for its use starting at 40 years old.
