Diagnosis of breast cancer in young women.
While the prognosis of younger women with breast cancer is controversial, there have been several significant reports indicating a more unfavourable outcome of the disease in this age group. A review has been conducted of the problems encountered in the diagnosis of breast cancer in younger women. The records of 227 consecutive patients aged 30-40 years who underwent breast biopsy were retrospectively analysed, and data studied in relation to the proportion of malignant to benign biopsies, the clinical and pathological features of the malignant cases, and the method of diagnosis. A total of 235 biopsies was performed in 227 patients, of which 199 were benign (85%) and 36 were malignant (15%), giving a malignant to benign biopsy ratio of 1:5.5. Thirty-six cancers were diagnosed in 35 patients. Among these young women with breast cancer, the average duration of symptoms was 26 weeks, the mean clinical cancer diameter was 3.3 cm and only a small proportion (28%) of women had early (Stage I) disease. There were 4 women with breast cancer (11%), in whom the diagnosis of malignancy was unsuspected preoperatively. Mammography in these younger women appears to have a more limited role, with a sensitivity of only 76%. These findings indicate that the diagnosis of breast cancer in younger women is often more difficult than in older age groups and that the presentation and detection of such cancers is often delayed. Younger women need to be educated in relation to seeking early medical review of breast lumps and clinicians need to be aware of the limitations of mammography in such cases.
