TL;DR: This evidence provides no basis for the promotion of mammographic screening in women under age 50 in the general population, and appropriate information including the fact that there has been no demonstrated ultimate benefit should be given.
Abstract: We reviewed the evidence relating to breast screening using mammography in younger women, primarily those aged 40 to 49. The best evidence comes from the 6 published randomized trials. We performed a metaanalysis, assessing the breast cancer death rates for each year of follow-up in each trial, and producing summary estimates of the cumulative and year-specific mortality rates. At 7 to 10 years, death rates in screened and unscreened groups are similar. This lack of benefit contrasts with the average 30% mortality reduction in women over age 50 in the same trials. This evidence provides no basis for the promotion of mammographic screening in women under age 50 in the general population. If mammography is to be offered to asymptomatic women of that age who request it, appropriate information including the fact that there has been no demonstrated ultimate benefit should be given. The difference in effectiveness may relate both to the greater difficulty in distinguishing normal from abnormal tissue, and to greater growth speed and different biological characteristics of tumors, in younger women. We also reviewed recommendations from major groups: in general multidisciplinary bodies which rely on structured evaluations do not recommend screening in younger women, while many other specialty associations and cancer societies do. Overall, the trials of screening of younger women show a small increase in mortality in those screened, and possible explanations of this are discussed. [corrected] Remaining questions concern the precise age at which effectiveness changes, the situation in high-risk women, and the impact of improved or more frequent screening.

TL;DR: It is of paramount importance to evaluate the impact of participation in organized mammography service screening independently from changes in breast cancer treatment, which can be done by measuring the incidence of fatal breast cancer.

TL;DR: In this paper, a 46-year-old woman who presents to her doctor for a well-woman examination informed her that her 51-year old friend was diagnosed with breast cancer one month ago and that she is worried about getting breast cancer.
Abstract: Case study: GK is a 46-year-old woman who presents to your office for a well-woman examination. She informs you that her 51-year-old friend was diagnosed with breast cancer one month ago and that she is worried about getting breast cancer. On further inquiry, you learn that she delivered her only child when she was 32 years of age and has no family history for breast cancer.

TL;DR: A prospective study of 622 consecutively registered patients with 650 breast tumors was performed to appraise the reliability of combined physical examination, mammography, and fine‐needle puncture (triple test) in the preoperative diagnosis of such tumors.
Abstract: A prospective study of 622 consecutively registered patients with 650 breast tumors was performed to appraise the reliability of combined physical examination, mammography, and fine-needle puncture (triple test) in the preoperative diagnosis of such tumors All malignant as well as benign test results were confirmed by subsequent histologic examination The diagnostic accuracy of the triple test at benign changes is comparable to that of histologic examination, but participation of experienced radiologists and cytologists as well as persons skilled in fine-needle puncture is required Twenty-eight percent of the planned excisional biopsies were made superfluous by the fine-needle puncture, which immediately revealed the tumor as a cyst, abscess, or hematoma For this reason, too, fine-needle puncture is recommended as a routine procedure
