[Does breast-feeding prevent breast cancer?].

Many epidemiological studies show clearly the restraining effect of breast-feeding on breast cancer. So it could be shown that breast-feeding for one year reduces the individual risk for premenopausal breast cancer by 45%. The risk of postmenopausal breast cancer in the developed countries could be decreased by 42% by increasing the breast-feeding time in life. Most authors assume that the protective value of breast-feeding is hormone-conditioned. Further theoretical implications result from the increasing knowledge of the immunologic characteristics of the mother's milk. Beside well-known positive effects of breast-feeding on children's health, breast-feeding should also be further promoted from the view of women's health.

A case-control study of parity, age at first full-term pregnancy, breast feeding and breast cancer in Taiwanese women.

A hospital-based case-control study was designed herein to investigate the relationship between parity, breast feeding and breast cancer in Taiwan. Reproductive histories of patients with breast cancer confirmed by either pathology or cytology were assessed by questionnaire and compared with age-matched healthy controls. One hundred and fourteen cases and 228 age-matched controls were recruited for this study. According to those results, women having had more than three full-term pregnancies, age at first full-term pregnancy younger than 30, and breast feeding for more than 3 years displayed significantly protective effects against breast cancer. Following adjustment for ethnicity and menopausal status, women with more than three full-term pregnancies and younger than 30 years old at first full-term pregnancy had a decreased risk of breast cancer. However, duration of breast feeding was not related to breast cancer, after adjustment for ethnicity and menopausal status. The effect of number of full-term pregnancies on the risk of breast cancer was found to be independent of the effect of age at first full-term pregnancy. Moreover, the effect of age at first full-term pregnancy and number of full-term pregnancies was also independent of the effect of breast feeding.

The relationship between pacifier use, bottle feeding and breast feeding.

OBJECTIVE: To investigate the influence of pacifier use and the introduction of formula milk on breast feeding. METHODS: The mothers of 356 healthy newborn infants who initiated breast feeding while in-patients were interviewed within 3 days of birth and later at 2 and 6 months postpartum. Information regarding previous birth, breast-feeding frequency, pacifier use and the adoption of formula milk were obtained. The data were analyzed using chi2 and Kruskal-Wallis tests. RESULTS: At the end of the second month, 264 (74%) of the mothers were still breast feeding; by the end of the sixth month this had fallen to 236 (66%). Among the 356 mothers, 152 had at least one previous infant, and 132 (86.8%) of them had breast fed a previous infant. Of the women who breast fed their previous infant for more than 2 months, 112 (84.8%) breast fed the current child until the end of the second month and 104 (78.7%) until the end of the sixth month after delivery. Of all investigated patients, 204 were primiparous (57.3%). Of these, 152 (74.5%) breast fed until the end of the second month, and 132 (64.7%) until the end of the sixth month after delivery. Amongthe 204 primiparae, 92 (45%) gave formula to their newborn infants. Forty-four of these 92 mothers (47.8%) had discontinued breast feeding by the end of the second month. Among the 356 newborn infants, 220 used pacifiers at the end of the second month. Within this group, 72 (33%) of the infants did not breast feed, while 148 (67%) did breast feed. Of all investigated mothers, 136 did not give pacifiers to their infants and only eight of these mothers (6%) had stopped breast feeding at the end of the second month. CONCLUSIONS: We found an inverse correlation between pacifier usage and breast feeding. Breast feeding was most common among multiparous mothers.

Effect of naloxone on neurohypophyseal peptide responses to breast feeding and breast stimulation in man.

We have investigated the role of endogenous opioid peptides in the release of oxytocin (OT) in response to breast feeding and breast stimulation in humans. Five breast feeding women were studied on two separate occasions within 4 weeks of delivery. Saline or naloxone, 4 mg bolus and 6 mg/h, was administered intravenously, in random order. Blood samples were taken at regular intervals. In the saline-infused group OT rose from a baseline of 1.1 +/- 0.1 pmol/l (mean +/- SEM) to a peak of 7.0 +/- 0.9 after 6 min, and in the naloxone-infused group from 1.0 +/- 0.1 pmol/l to 5.8 +/- 1.3 (P less than 0.05). There were no significant differences between the two groups at any time point. Plasma vasopressin (AVP) did not change. In the second study six women in the luteal phase of the menstrual cycle were investigated on two occasions at least 48 h apart. They were similarly infused with either naloxone or saline in random sequence. A mechanical breast pump provided breast stimulation. In saline-infused women OT levels rose from a baseline of 1.0 +/- 0.1 pmol/l (mean +/- SEM) to a peak of 3.0 +/- 1.1 (P less than 0.05) after 6 min, and in naloxone infused women from 1.1 +/- 0.1 pmol/l to 3.0 +/- 1.4 (NS). There were no differences in OT between the groups. AVP did not change. We conclude that endogenous opioid peptides do not modulate OT release during breast feeding or breast stimulation in women.

Effect of the method of breast feeding on breast engorgement, mastitis and infantile colic.

This exploratory study compared the effect of two methods of breast feeding on breast engorgement, mastitis, infantile colic and duration of breast feeding. An opportunity sample of subjects was assigned either to the experimental group (prolonged emptying of one breast at each feed) (n = 150) or to the control group (both breasts equally drained at each feed) (n = 152) and both groups were followed prospectively to 6 months after delivery. The experimental group had a lower incidence of breast engorgement in the first week (61.4% versus 74.3%; p < 0.02) and colic over the first 6 months (12% versus 23.4%; p < 0.02). There was no significant difference between the two groups in the incidence of mastitis over 6 months and the length of breast feeding (16.5 +/- 10.3 weeks versus 17.5 +/- 10 weeks experimental versus control group). The majority of mothers in the experimental group (63%) felt it necessary to offer the second breast at the end of a feed to satisfy their infant's hunger. The "perceived insufficient milk supply syndrome" was the main reason given for cessation of breast feeding in both groups. This study provides data to advise nursing mothers about these two methods of breast feeding.

Breast feeding and breast cancer.

Clinicians who deal with numerous cases of breast cancer are aware of the fact that there is some relationship between childbearing and breast cancer, and also that nulliparous women are probably more prone to breast cancer than their parous sister. however, a relationship between breast feeding and breast cancer is not certain. This is a preliminary report on a study of the breast feeding habits of breast cancer patients and non-cancerous patients, after an attempt was made to match controls for parity and age.

Breast feeding.

Breast feeding is becoming more popular among all socioeconomic classes. By providing instruction and care of the mother and infant, the physician can greatly enhance the chances for success. Although breast feeding is a natural function, the proper technique needs to be learned. There are relatively few contraindications. The infant requires vitamin K at the first opportunity and supplementation with vitamin D and fluoride as necessary. Recommended daily dietary allowances are increased for nursing mothers. The physician must understand the effects of different contraceptive methods on lactation.

[Behavior and opinions of health care personnel with regard to breast feeding].

Breast feeding (BF) practice is related to cultural, social and economic patterns of the future mothers; nevertheless hospital personnel seems to have some influence on infant feeding habits. This study describes the professional practices among personnel in the maternity hospitals of the Departement de la Seine Maritime (France) and reports their opinions about BF. Most of the respondents consider that they have a small role in influencing the decision to breast feed, the choice being made before pregnancy. Delivery training sessions seem to be the most suitable time for information about BF. Psychological arguments are considered as the most effective approach. BF is not estimated as leading to an increased work goal by hospital personnel. BF appears to be generally well controlled by mothers before discharge. Technical factors were given as the primary influencing reason for cessation of BF. This survey indicates several ways for establishing future health education programs for the promotion of BF.

Representing infant feeding: content analysis of British media portrayals of bottle feeding and breast feeding.

OBJECTIVE: To examine how breast feeding and bottle feeding are represented by the British media. DESIGN: Content analysis. SUBJECTS: Television programmes and newspaper articles that made reference to infant feeding during March 1999. SETTING: UK mass media. MAIN OUTCOME MEASURES: Visual and verbal references to breast or bottle feeding in newspapers and television programmes. RESULTS: Overall, 235 references to infant feeding were identified in the television sample and 38 in the newspaper sample. Bottle feeding was shown more often than breast feeding and was presented as less problematic. Bottle feeding was associated with "ordinary" families whereas breast feeding was associated with middle class or celebrity women. The health risks of formula milk and the health benefits of breast feeding were rarely mentioned. CONCLUSIONS: The media rarely present positive information on breast feeding, even though this feeding practice is associated with the most health benefits. Health professionals and policy makers should be aware of patterns in media coverage and the cultural background within which women make decisions about infant feeding.

Unilateral breast-feeding and breast cancer.

Women of fishing villages in Hong Kong by custom breast-feed with only the right breast. The hypothesis that the unsuckled breast may have an altered risk of cancer development was investigated. Records of the radiotherapy divisions in Hong Kong between 1958 and 1975 were searched, and breast-cancer patients were interviewed for a detailed history of lactation. The overall left/right ratio of cancer in the breasts of 2372 women with unilateral breast carcinoma was 0-97, indicating that breast cancer was equally distributed between the two sides. Of 73 patients with a history of exclusively one-sided breast-feeding, 27 of 34 patients aged 55 or over (79-4%) and 19 of 39 patients under age 55 (48-7%) had a carcinoma in the unsuckled breast. Comparisons of patients who had nursed unilaterally with nulliparous patients and with patients who had borne children but had not breast-fed indicated a highly significant increased risk of cancer in the unsuckled breast. No statistically significant differences in laterality of breast cancer were found in 52 patients who had for convenience nursed to a greater extent from one side than the other. This study indicates that in post-menopausal women who have breast-fed unilaterally, the risk of cancer is significantly higher in the unsuckled breast and that breast-feeding may help to protect the suckled breast against cancer.

[Breast feeding following breast reduction-plasty and mastopexy?].

A certain amount of breast tissue remains connected with the nipple after aesthetic breast surgery, except in cases of free nipple grafting. Breast feeding is therefore possible. The obstetrician or the midwife are often with the question, whether breast feeding can be recommended. In this study we have investigated, whether lactation is adversely affected by breast surgery. 105 patients who had been operated for unilateral or bilateral mammahyperplasia or mammoptosis, were examined and questioned about breast feeding after operation. The operative techniques of McKissock, Pitanguy and Strömbeck had been used. Breast feeding attitude of our patients was compared with a corresponding collective without breast surgery from the 2nd University Clinic, Gynaecological Department. Five of 14 patients breastfed their babies. The remaining patients did not breastfeed, either after having been counselled not to breastfeed or because of admission of the newborn to a neonatal care unit. Only in two patients no lactation was observed. In our opinion, patients should be informed and encouraged, that breastfeeding is possible after aesthetic breast surgery.
