The knowledge and practice of breast self-examination (BSE) was investigated among 500 women with operable breast tumors between 35 and 64 yrs of age (all successively operated) and 652 healthy women, matched with the previous group for 5-year age groups from 35 to 54 yrs. Only 39.9% of breast cancer women and 34.5% of the control practiced BSE, and only a third of these did it monthly. Such practice tends to progressively decrease starting from 45 yr, and it is used less frequently by the women with a poor education and those in a lower economic bracket. Among the 500 breast cancer patients, those who practiced the self-examination had a higher number of tumors with a diameter no greater than 2 cm and a lower number with a diameter larger than 4 cm. In addition in this group the percentage of unaffected axillary lymph nodes (N-) was 58.8% compared to 48.8% for the group that did not practice self-examination, and the percentage of the cases with more than 3 metastatic lymph nodes (N+>3), was 20.0% in the first group and 27.3% of the second one. These differences are statistically significant. The correlation between tumor diameter and the histologic lymph node stage is equally evident since there is a progressive reduction in N- cases, and a contemporary progressive increase in N+ (>3) cases with increasing breast tumor diameters. Therefore, we can infer that the lack of practice of BSE causes a diagnostic and therapeutic delay, which is reponsible for aggravation of the prognosis.
