SR | Adding ultrasound to mammography increases breast cancer detection, but increases false-positives and biopsies
3 Apr, 2023 | 13:55h | UTCSummary: The systematic review examined the effectiveness and safety of combining mammography with breast ultrasonography versus mammography alone for breast cancer screening in women at average risk. The research included one randomized controlled trial, two prospective cohort studies, and five retrospective cohort studies, involving a total of 209,207 women.
High certainty evidence from one trial indicated that combining mammography with ultrasonography led to the detection of more breast cancer cases than mammography alone (5 vs. 3 per 1000 women). However, this combination also led to a higher number of false-positive results and biopsies. For every 1000 women screened with the combined approach, 37 more received a false-positive result, and 27 more women underwent a biopsy.
Secondary analysis of the trial data revealed that in women with dense breasts, the combined screening detected more cancer cases than mammography alone, while cohort studies for women with non-dense breasts showed no statistically significant difference between the two screening methods.
The included studies did not analyze whether the higher number of detected cancers with the combined screening method resulted in lower mortality rates compared to mammography alone. Further research, including randomized controlled trials or prospective cohort studies with longer observation periods, is needed to assess the impact of the two screening interventions on morbidity and mortality.

Commentary on Twitter
Exemestane 25 mg (Exe) 3x/week (TIW) in compliant patients is comparable to daily dosing in reducing circulating estradiol; a weekly dose was less effective. Toxicity similar in all arms, suggesting Exe TIW may be used in breast cancer prevention. https://t.co/2NugINVrim #BCS

Study shows a slight breast cancer risk increase with progestogen-only birth control, comparable to combined oral methods
29 Mar, 2023 | 13:35h | UTCSummary: A UK study and meta-analysis examined breast cancer risk linked to hormonal contraceptives, emphasizing progestagen-only contraceptives in premenopausal women. Utilizing a nested case-control design with the Clinical Practice Research Datalink (CPRD), a primary care database, the study included 9,498 women under 50 diagnosed with invasive breast cancer between 1996 and 2017, and 18,171 closely matched controls. The meta-analysis merged CPRD findings with 12 observational studies on progestagen-only preparations.
The results revealed that current or recent use of combined oral contraceptives, oral progestagen-only contraceptives, injectable progestagen, and progestagen intrauterine devices all led to a similar increase in breast cancer risk. The 15-year absolute excess risk associated with five years of oral combined or progestagen-only contraceptive use ranged from 8 per 100,000 users aged 16-20 to 265 per 100,000 users aged 35-39. The study concluded that both contraceptive types were linked to a slight breast cancer risk increase, and these risks must be weighed against the benefits of contraceptive use during childbearing years.
