Stagnant⁤ Mortality Rates

Breast ⁤cancer mortality rates have stopped decreasing⁤ for women over 74 and under 40, primarily due to an increase in advanced-stage diagnoses, according to a study published⁤ in​ the ⁢ Journal of Breast Imaging.

The study confirms previous findings that mortality rates in women under 40 have remained unchanged. The lack of progress in⁢ decreasing mortality among older women is a newly observed‍ trend.

Breast cancer remains a important health ​concern,ranking ‍as the second leading cause of ‍cancer‌ deaths among American women. in 2024, it accounted for over 42,000 deaths.

Before 1990,‌ breast cancer ⁣incidence was on the rise,‌ and mortality ⁤rates⁤ were either stable or⁢ increasing. However, since 1990, deaths from⁢ breast cancer have steadily declined,⁢ largely ‍attributed to‍ widespread mammography and⁤ advancements in ⁣treatment.

Researchers analyzed cancer mortality rates collected and maintained by the National Center for Health ⁢Statistics since 1990.

breast cancer mortality rates for American women decreased by 43.5% from 1990 to 2022. The most ⁤recent trend showed a decrease of​ 1.23% per year from 2010 to 2022, the lowest rate as 1990.

Age​ and Racial Disparities

Among Americans ages 20 to 39 (across all races/ethnicities), breast ‍cancer mortality‍ rates decreased by ‍2.79% per year from 1990 to 2010 but have since remained‍ stable.

The analysis‌ revealed that for women 75 and⁣ older, the breast cancer mortality ‌rate ⁢decreased by 1.26% per year from 1993 to 2013, after which the​ rate ceased to decline.

Breast cancer mortality has also ceased to decrease​ in the latest⁢ period for Asian women (since 2009), Hispanic women (since 2008), and ⁢Native American women.

previous research⁢ indicated⁤ that breast cancer mortality rates stopped decreasing for women under 40 in​ 2010.

The new analysis found that the end of the decline in mortality rate in both younger and older groups ⁣was⁤ primarily driven by ⁢the fact that mortality rates have not decreased for white women under 40 and over 74. Unfavorable trends ​were also​ observed for ⁣Hispanic women ages 20 to 39 and Native American ​women 75 and older. Mortality ⁤rates from breast cancer in ‍women ​of colour have continued to decrease ​in all age groups.

Potential Causes of‌ Stagnation

Researchers suggest that ⁣the stagnation in mortality⁢ rate decreases for women under 40 ‍and over 74 is due ​to a significant increase in ‍stage IV breast cancer​ diagnoses in these age ⁣groups.

Stage IV (metastatic) ‍breast cancer at diagnosis‍ carries a poor ⁢prognosis, with⁤ a 5-year survival rate ‌of 31%.

The study indicates that increased rates ⁤of advanced-stage ‌diagnoses are a key reason why breast cancer mortality is no longer decreasing at​ the previous rate.

Researchers suggest this trend may​ be linked to medical assistance protocols.

While the medical ‌community ​in the⁤ United States generally recommends breast cancer evaluation for all women up to age 25, breast cancer screening ⁢is typically recommended only for women under 40 who have a higher-than-average risk. Some​ recommendations discourage screening ⁤for⁤ women over 74.

According to the study, the ⁢ratio between breast cancer rates in ​Black⁢ women and white women‍ shows the​ biggest gap for women ⁣under 40, suggesting that ⁣younger women need alternatives to⁣ current strategies⁣ for breast cancer evaluation, screening, and treatment.

The fact that breast cancer mortality has ceased‌ to ⁣decrease for women ⁣over 74 is a new ​alarming trend.

This is compounded by the fact ⁢that​ women under 40 are ⁤not seeing decreasing‌ mortality‌ rates from ⁤breast ‌cancer. These groups are precisely those discouraged from breast cancer‌ screening by⁤ some recommendations in​ the United ⁢States.
