InterestHigh interest

People show high curiosity and concern, actively discussing various studies and implications.

EngagementModerate engagement

Comments range from brief acknowledgments to detailed requests for evidence and debate, indicating moderate to high engagement.

ImpactModerate impact

The collective discussions highlight awareness of the potential health risks, suggesting a moderate impact on public perception and decision-making.

Abstract in brief

  • This study found that the use of contemporary hormonal contraception is associated with a slightly increased risk of invasive breast cancer, especially with long-term use of more than 10 years.
  • The risk remains elevated even after stopping contraception, particularly for women who used it for 5 years or more, with current or recent users experiencing a 20-38% higher risk compared to non-users.
  • Although there is an increased relative risk, the overall absolute increase in breast cancer cases among users is small, roughly 1 extra case per 7,690 women, indicating that while there's a potential risk, it is limited in scale.

経口避妊薬と乳がんの関係性。 ざっくり言うと7500人が経口避妊薬を飲むと、1人が経口避妊薬が影響し乳がんになる計算。5年以内の内服期間なら、ほぼ影響なし。薬の種類の差もほぼなし。 経口避妊薬も必要だから飲むわけで、これによる乳がんを過度に心配する必要はなさそう。 https://t.co/0sVLmInpNv

As such, I encourage non-hormonal IUD or other non-hormonal options. #bcsm https://t.co/okgO39nOG7

@laura_jackson79 @robert8841 @MeHitchc0ck 50% is not typical for everyone. Relative risk depends on a ton of factors -- age, weight, types of estrogen receptors, activity levels, etc. The article I linked to is based on this paper, & their study found "1 extra breast cancer for every 7690 women". https://t.co/TYchZFgnDK
