6. BRIEF RESUME OF THE INTENDED WORK
INTRODUCTION
Cancer is one of the leading causes of mortality and morbidity in developed as well as developing countries. Breast cancer is the most common malignancy among women and rare among the men. The incidences of breast cancer increased approximately 74% between 1965-96, numbers are going up with an estimate of 80,000 new cases being diagnosed annually.1
There is a rising incidence of breast cancer in India. According to the International Agency of Research on cancer, which is part of WHO, there were approximately 79000 women per year affected by breast cancer in India in 2002 and over 87,000 women in 2003.2
Breast Self Examination has long been recommended by health care practitioners as a complement to mammography and clinical breast examination. Only a small percentage report doing breast self examination procedure proficiently. The individual and group training in Breast Self Examination with guided practice improved to measure of search, depth of palpation and duration of search time.3
6.1 NEED FOR THE STUDY
Breast Self Examination is less economic than mammography. Breast cancer can be detected earlier and survival rate of women can be improved. Rural population has less access to medical care facilities and their educational status is lower. There fore it is essential to educate them about breast cancer, is prevention and the early detection by systemic Breast Self Examination. The risk of developing breast cancer begins to rise in the early thirties and peaks by the time a woman enter a sixth decade of life. A teaching programme to women between the age group of 30 – 60 years would be highly beneficial because they are the high risk group. Improved knowledge about breast cancer and ability to perform breast self examination at this age would be effective, because of the perceived threat of breast cancer should motivate them to practice breast self examination regularly.4
A study revealed that five year survival rate of Breast Cancer patients, 75% has been observed self examiners and recommended that 50% of all Breast Cancer patients world wide could obtain a prolongation by increasing public awareness by early detection and efficient treatment at the community level.5
A study was conducted to find the effectiveness of planned teaching programme regarding Cancer prevention and early detection among 50 teacher trainees in Karnataka in terms of other knowledge. An evaluate research approach was used for the study. The mean post test knowledge scores of the teacher’s trainees (60%) were significantly higher than the mean pre-test knowledge scores (40%).6
According to researcher’s clinical and community experience found that women do not have adequate information about breast Cancer and BSE. On this basis the researcher wish to conduct to evaluate their knowledge regarding risk factors of Breast Cancer and Breast self Examination in a view to develop planned teaching programme among women in selected rural community.
3.2 REVIEW OF LITERATURE
Literature review involves the systematic identification, scrutiny of summary of written materials that contain information in a problem7.
Review of literature has been divided under the following headings.
a) Breast cancer and risk factors
b) Knowledge of breast cancer and early detection
c) Breast cancer and breast self examination
d) Effectiveness of planned teaching programme
a. BREAST CANCER AND RISK FACTORS
Breast cancer is the most common form of cancer among women. A number of studies have highlighted the importance of information to women regarding breast cancer and risk factors. Because the definite cause of breast cancer is not known. There are various risk factors which predispose women to develop breast cancer.
A study was conducted to assess the prevalence of pre malignant lesion in prophylactically removed breast from women at hereditary risk for breast cancer. Prospective methods of breast specimens were taken from 67 women at Geneva. In 57% of the women, one or more different types of high risk histopathologic lesion were present 37% a typical tubular hyperplasia, 39% a typical ductal carcinoma in situ. This study supported the hereditary risk factors.8
A study was conducted to estimate the familiar predisposition to the breast cancer in a British population according to the age of the individual at risk and the age at which the relative was affected. Familiar relative risks were computed by comparing breast cancer incidence in relatives of 2009 breast cancer cases from a population. Form the data the authors estimated that in the general population 6.8% of women under the age of 50 years, 9.7% of women aged 50-60 years have at least a first degree relative affected with breast cancer. The women under 50 years have a positive family history which confirms an increased risk of at least 2.5 fold.9
b. KNOWLEDGE OF BREAST CANCER AND EARLY DETECTION
Breast cancer detection at an early stage by various training programmes before the disease has spreads beyond the breast improves the chances of cure and normal life. Breast self examination should be part of every woman’s monthly health care routine.
A study was conducted in Jordan to describe the level of breast cancer awareness and breast self examination among women nurses and teachers according to selected demographic variables, such as education, age, religion, insurance and family history of breast cancer. The study instrument was based on knowledge based questionnaire on Breast Self Examination and breast cancer awareness. Analysis of co-variance indicated that family history was associated with general breast cancer awareness. Professional age and family history significantly influences breast cancer and breast self examination awareness. The nurses were 38.3%, compared with 73.17% for teachers. These result provide women nurses and teachers in Jordan might be useful for developing future prevention and screening education programmes.10
A study was done in Leningrad on the effectiveness of early detection of breast cancer by Breast Self Examination in view of reduction of mortality. The study was done by having a control group comprising 31066 women and an experimental group that the breast Self Examination group comprising 31186 women. The number of breast cancer patients detected within the period of 15 months was 36 cases in the Breast Self group (1.15 per 1000 breast self examination taught women) and 16 cases in the control group (0.51 per 1000 women). The average size of the tumour detected was 1.3cms smaller in the Breast Self Examination group. Tumours larger than 5cms were more than double the number in the control group that is 37.5% versus 16.7%.11
c. BREAST CANCER AND BREST SELF EXAMINATION
The appropriate breast cancer screening measures currently is secondary prevention through early detection with breast self examination and mammography which offers a greatest hope for reducing mortality and improving survival. Among this breast self examination is the most cost effective simple method.
A study was conducted among 145 Thai women in Brisbane recruited through a snowball sample method, which used personal contacts and key person within the Thai community. Using the Health Belief Model (HBM) for identify socio demographic variables, 25% of the women performed breast self examination regularly. Beliefs in high personal susceptibility to breast cancer strongly increased the likelihood of Breast Self Examination. After adjusting for potential confounding were found to be important determinants of regular BSE.12
An experimental study was reported that teaching breast self care as breast changes occur in the 50 adolescent girls can influence positive behaviour such as performing Breast Self Examination and seeking regular professional Breast Examinations. Pre-test knowledge was assessed on knowledge; teaching one time interventions were carried out, and post test knowledge was assessed, return demonstration of Breast Self Examination was done by students on model with lumps on it. Descriptive statistics were used to analyze the knowledge and practice of Breast Self Examination. Analysis of variance was used to examine the differences between knowledge scores Pearson correlations were used to examine the relation between knowledge and health beliefs. There were no significance correlation between knowledge and perceived susceptibility between knowledge and perceive seriousness. Knowledge and practice of Breast Self Examination correlation were significant, 23.2% reported regular practice. Study supported the proposal of one time intervention can produce and increasing knowledge of Breast Self Examination and breast cancer in adolescent.13
A study was conducted to determine the knowledge and frequency of Breast Self Examination among Middle Eastern Asian Islamic Immigrant women residing in a metropolitan U.S. city. The purpose sample consisted of 39 Middle Eastern Asian Islamic immigrant sample women ranging in age from 20 to 40 years (mean 33, SD 8.29). Data was collected by Champion’s Breast Self Examination. The results indicated that 33 women (85%) had beard of Breast Self Examination and 29 women 74% had not examined their breasts for lumps. The result of this study showed that Middle Eastern Asian immigrant women may be a population over looked by health care professionals in the education of breast Self Examination. Suggestions to improve breast cancer screening practices among this population were provided.14
d. EFFECTIVENESS OF PLANNED TEACHING PROGRAMME
This section of the review of the literature reports on selected studies on effectiveness of planned teaching programme which will help a person to take care of himself.
A study was conducted to determine the effectiveness of a planned teaching programme on early detection of Breast Cancer and BSE among women. The study adopted evaluative approach with pre-test control group design. The data were collected structured interview schedule and observational checklist. Findings showed that there was significant difference between pre test (K1=40%) post test (K2=55%) and post test II (k2=45%) knowledge score and ability scores. This indicated that planned teaching programme contributed to enhance knowledge and ability scores regarding prevention of Breast Cancer and BSE .15
A study was conducted to determine the effectiveness of a planned teaching programme on prevention of Breast Cancer among 50 women in the community at Uduppi District. The research approach used was evaluative approach with one group pre test-post test, pre experimental design. Descriptive and inferential statistics were used to analyse the data. The planned teaching programme was found to be effective in increasing the knowledge of women on prevention of breast cancer with 49 ±7.86, P<0.05 and ability to perform BSE with 49 ± 12.64, P<0.05.16
