Final answer:
A 40-year-old should generally have her next mammogram in one to two years, depending on individual risk factors.
Step-by-step explanation:
The current guidelines for routine mammogram screenings recommend that women begin at age 40 and continue to receive them every one to two years. The exact frequency may vary depending on individual risk factors and family history. Therefore, a 40-year-old woman who has just received her baseline mammogram would likely be advised to have the next mammogram in one to two years unless told otherwise by her healthcare provider based on personal risk factors.
It's important to distinguish between mammogram screening and Pap smear guidelines, as the two are for different types of cancer screenings - breast and cervical cancer, respectively. As outlined, Pap smears are recommended starting at age 21 and follow a different frequency schedule. Always consult with a healthcare provider for personalized screening recommendations.
