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.
