Background: Breast cancer is the most prevalent cancer in women worldwide and its frequency is increasing gradually in many countries. Over the last three decades an increase in the breast cancer has been witnessed in the earlier low-risk Asian countries including Pakistan. Purpose: The objective of the current study was to assess the prevalence of known risk factors like early menarche, late menopause, socio economic, reproductive and demographic factors, among women diagnosed with breast cancer at INMOL hospital, Lahore, Punjab, as little information exists in this regard. Materials and Methods: A survey study was conducted on 200 women diagnosed with breast cancer who were seen at Institute of Nuclear Medicine and Oncology (INMOL) hospital, Lahore. A structured questionnaire was administered to these patients regarding the known risk factors through face to face interviews after obtaining appropriate consent. Results: Regarding non-modifiable risk factors, our study showed that majority of the breast cancer patients were diagnosed at 35-45 years (32.5%) or at older age (${\leq}46$) and experienced menarche at 12 years or older (66 %). Likewise, a large number of patients reached menopause at the age of 45 years (60%), had no family and personal history of breast cancer (80%) and hence fell in a low risk category. Regarding modifiable risk factors in women diagnosed with breast cancer, most of the patients fell in low risk strata as the majority were married (98%) at young age, breastfed their children for 12 months or more (88%) and bore two to three children (80%). Considering income criteria, the majority of the patients had a low risk profile as they belonged to middle class (70%), urban area (60%) and were house wives (80%). However, it was noted that a considerable number of women (34%) diagnosed with breast cancer experienced menarche at an early age (<12) and reached menopause after the age of 45 years. This situation is further augmented by environmental changes and dietary habits and places them in a high risk category.

Menarche is a main indicator of sexual maturity which relates to a reproductive function. The onset of the menstrual cycle differs individually and is influenced by many variables such as socio-economic situation, race, genetics, climate, altitude, nutritional status, and physical growth. Among them physical growth has been known to be the most influencing factor, particularly when expressed as body fat designated by weight. This study intended to investigate the body composition of girls around the menarche period and to evaluate the minimal levels of weight and fat percentage needed for the onset of menarche. A total of 101 female subjects, aged 11 to 13 years, were recruited from the 5th and 6th grades of an elementary school, in Mokpo, Korea. The subjects were placed into one of two groups Pre-menarche and Post-menarche groups according to their experience with menarche. Thereafter, the subjects in the Post-group were placed into 4 subgroups based on the number of menstruations they experienced: Post-I (1-3 times), Post-II (4-6 times), Post-III (7-9 times), and Post-IV (> 10 times). The average age at the onset of menarche of the subjects in Post groups was $11.2 \pm 0.6$ years. There were significant differences in the data of anthropometry and body composition between the Pre and Post groups, although the mean ages of both Pre and Post groups were the same. Weight, waist, hip and thigh girths, fat percentage, and lean body mass of the Post groups were significantly higher than those of the Pre group. Height was not significantly different between the groups. Weight was highly correlated with body fat mass (r = 0.92. p < 0.001), fat percentage (r = 0.85, p < 0.001), and body mass index (r = 0.91, p < 0.001) These results indicate that weight, compared with height, reflects body composition well and influences the onset of the menstrual cycle. It could also be suggested that the minimal weight and fat percentage needed for the onset of menarche in Korean females are 41 kg and $17\%\;to\;19\%$, respectively.

This study was undertaken to investigate the interrelationship between the growth change of mandible and the developmental age of growing girls in the longitudinal data from 7 years to 15 years. The data were obtained from maturation stage of cervical vertebrae through the serial lateral cephalogram, height increment records which was taken at one year interval, menarche date through interview. On the basis of findings of this study, the following conclusions were obtained. 1. In general the growth of mandible (Ar-Pog, Ar-Go, Go-Pog) showed two peaks of growth velocity. 2. The maximum growth of mandible (Ar-Pog, Ar-Go, Go-Pog) almost appeared between stage 3 and stage 4 in maturation of cervical vertebrae. 3. It showed the tendency that the maximum increment of height appeared faster than that of mandible (Ar-Pog, Ar-Go, Pog-Go). 4. The maximum growth of height almost appeared between stage 2 and stage 3 in maturation of cervical vertebrae. 5. It showed the tendency that the menarche appeared later than the maximum growth of mandible (Ar-Pog, Ar-Go, Pog-Go). 6. The menarche almost appeared at stage 4, stage 5 in maturation of cervical vertebrae.

Purpose: The purpose of this study was to understand the reconstruction experience of mothers who had recently experienced a late-school age daughter's menarche by utilizing a hermeneutic phenomenological research methodology based on Parse's human becoming theory. Data were collected using purposive and snowball sampling methods to recruit the mothers of elementary fifth- and sixth-grade girls recently experiencing menarche. The data were analyzed using Parse's research methodology. As a result, the mothers' experiences appeared as "the process of reconstructing the menarche-related values created by themselves by facing the child's menarche experiences and related responses along with the change of era." The key concepts of there construction experiences of the mothers were "experiencing an ambivalent feeling of pity and pride," "celebrating her instead of expressing concerns," "giving a traditional lesson of protecting oneself to a new generation," and "feeling empathy as a woman and also alienation due to the generational gap." These findings reveal the important roles and competencies of community and school nurses in terms of achieving a healthy and positive reconstruction experience for mothers and their daughters. Also, it is necessary to develop educational programs for mothers who are about to encounter their daughters' menarche.
