When comparing the prognosis of pregnant women with breast cancer to nonpregnant women, what is true?

• A. It is worse for pregnant women.
• B. It is better for pregnant women.
• C. It does not differ when matched for age and stage of disease.
• D. There is insufficient data to compare.

Answer: (C)

When examining the prognosis of pregnant women with breast cancer compared to nonpregnant women, there is significant evidence suggesting that when matched for age and stage of disease, the outcomes do not differ significantly between the two groups. This means that if pregnant women are treated similarly to their nonpregnant counterparts, considering factors like age and the extent of the cancer at diagnosis, their prognosis can be quite comparable. Research has indicated that, while breast cancer during pregnancy can present unique challenges in terms of treatment options and timing, the biological behavior of the cancer does not inherently differ based on pregnancy status when these factors are controlled for. This challenges the notion that being pregnant automatically leads to a worse prognosis—it's crucial to understand that the stage of the disease at diagnosis plays a pivotal role in forecasting outcomes, regardless of pregnancy.
