“…Equivalent findings have been reported from Southampton Health District (UK) 13 and from New South Wales. 12,14 The lower average stage at presentation should eventually translate into a better overall outcome for women who develop breast cancer. The same cannot be said of our finding that more tumours were both ER and PgR negative in 1994.…”

Objective To determine whether mammographic screening has affected the presentation of invasive breast cancer in Western Australia. Design Population‐based reviews of the presentation of all invasive breast cancers diagnosed in Western Australia in 1989 and 1994. Setting Western Australia (population 1.8 million). Active recruitment of women aged 50‐69 years for mammographie screening began in 1989. Main outcome measures Size and stage of invasive breast cancers at diagnosis. Results From 1989 to 1994, the age‐standardised incidence rose from 109 to 123 per 100000 woman‐years, based on 584 and 750 cases, respectively. The proportion of all invasive breast cancers detected as a result of a mammogram increased from 9.2% in 1989 to 34.5% in 1994. Among the cases where relevant information was recorded, the proportion of “impalpable” tumours increased from 7.7% in 1989 to 27.6% in 1994, and the average size of palpable tumours fell. There was an unexpected increase in the proportion of tumours that were negative on assays for oestrogen and progesterone receptors. Conclusions A relatively simple and inexpensive clinical review has boosted confidence that the outlay of public monies required to establish and conduct screening in Australia appears likely to yield the reductions in mortality from breast cancer that would be predicted on the basis of the earlier controlled trials of mammography.

“…Improved imaging of breast cancer and screening programmes increased the number of small breast tumours detected [9]. Furthermore, asymptomatic breast cancer, mainly detected during screening, is considered to be biologically less aggressive [10,11].…”

Systemic treatments for women with breast cancer: outcome with relation to screening for the disease

et al. 2003

Early detection and proper care of breast cancer are currently the best available approaches to the treatment of patients with the disease. In countries with a breast cancer screening programme, there has been a demonstrated reduction in breast cancer-related mortality. Such reduction has also been observed in Switzerland, a country in which no national programme of screening is available. Although there is no doubt that early diagnosis might have had a major role in reducing breast cancer mortality the magnitude of this effect is unknown. Research with tailored approaches on alternative imaging for early detection of breast cancer in high-risk women and on treatments offered according to proper criteria of responsiveness to therapies is warranted.
