Early breast cancer detection improves survival rates because better care may be given. Machine learning-based data categorization has been widely employed in breast cancer diagnosis and early detection. This literature review\'s primary focus is the categorization of accessible data using ML for breast cancer early pin-pointing and spotting. It is clear from reading multiple publications on artificial intelligence that there are several ways for detecting cancer. This study aims to compile reviews and technical publications on breast cancer diagnosis and prognosis. It provides an overview of the current research being done on various breast cancer datasets utilising data mining approaches to improve breast cancer detection and prognosis.

Introduction

I. INTRODUCTION

One of the worst illness in the world, cancer is especially hazardous in women since it often starts in the breast. Because of breast cancer, many women pass away. The doctor had a hard time classifying the disease because it takes a while to physically identify breast cancer.

Therefore, it is imperative to automate the diagnosis of cancer using multiple diagnostic procedures. According to the WHO, breast cancer is the cancer that poses the greatest risk to women worldwide. Additionally, it is the cancer kind that kills the most women worldwide. Breast cancer is the most frequent disease among women and has the greatest mortality rate from cancer in Malaysia, at about 25%. In Malaysia, 5% of women are thought to be at risk of breast cancer, compared to 12.5% in Europe and the US. It demonstrates that, in comparison to women from other nations, Malaysian women having breast cancer mostly  appear at a afterward stage of the illness.

Usually, if certain symptoms manifest, breast cancer can be quickly identified. Many women with breast cancer, nevertheless, show no symptoms.

Therefore, frequent breast cancer checking is crucial for early identification is necessary. Sri.Hari  conducted research on breast cancer, and the article was organised systematically as follows: We began by reviewing the existing literature before moving on to the suggested work. Following that concept, our suggested work uses it. It then shows how to choose features, and we discussed how to use a model to predict results before arriving at the predicted effort itself.

III. METHODOLOGY

A. Modules

1. Numpy:  It is a Python library that is used for scientific computing. It provides support for large, multi-dimensional arrays and matrices, along with a wide range of mathematical functions to operate on them. NumPy is an essential tool for numerical computing, data analysis, and machine learning.
2. Pandas: It is a Python library that provides powerful tools for data manipulation and analysis. It offers data structures such as DataFrames and Series, which allow for easy indexing, selection, and filtering of data. Pandas also provides functions for data cleaning, merging, and reshaping, making it a valuable tool for data preprocessing.
3. Scikit-learn: It provides a range of tools for data preprocessing, model selection, and evaluation, along with a variety of machine learning algorithms such as regression, classification, and clustering. Scikit-learn is a powerful tool for building machine learning models, and is widely used in industry and academia.

B. Machine Learning Algorithm

1. Random Forest: It is a powerful machine learning algorithm that combines multiple decision trees to make accurate predictions. It is versatile, handles high-dimensional data, and estimates feature importance. Random forest has been widely used in various fields and is an effective tool for classification and regression tasks.
2. SVM Algorithm: The "Support Vector Machine" method is one of the best machine learning techniques (SVM). It might be applied to both classification and regression issues. But categorization issues are typically employed. We represent each datum item as a point in n-dimensional space (where n is the number of highlights) with the approximate value of each component being the evaluation of a facility for this purpose. With the finding of the hyper plane that effectively divides the two classes, we carry out grouping at that theme.
3. K-Nearest Neighbor: KNN classifier is among the earliest and most straightforward techniques for generic, nonparametric classification. The distances between each sample in the training set and the test sample are then measured in this model. Following that, a simple majority vote is used to determine the test sample's class based on the labels of its KNN (K-nearest neighbors). The number of neighbours, or K, must be pre-defined in this categorization. To choose K in a way that results in the lowest misclassification error rate, it would be logical and practicable to employ trial and error.

C. Steps of Implementation

1. Data collection and pre-processing: The first step is to collect a dataset that contains features related to breast cancer such as age, tumor size, malignancy, and others. There are various public datasets available for breast cancer such as the Wisconsin Breast Cancer dataset. Additionally, data can be collected from hospitals and research institutions. 
2. Data Preprocessing: Preprocessing is a crucial step in machine learning. It involves data cleaning, normalization, feature scaling, and feature selection. The aim of preprocessing is to transform the raw data into a format that can be used for machine learning algorithms. For example, in breast cancer detection, preprocessing can include removing missing values, scaling the features, and selecting relevant features.
3. Data Training and Testing: After preprocessing the data, the next step is to split the dataset into training and testing data. The training data is used to train the machine learning algorithms, while the testing data is used to evaluate the performance of the algorithms. Typically, 70% of the dataset is used for training, and 30% is used for testing. 
4. Classification Using Different Algorithms: The next step is to train machine learning algorithms on the training data. In this case, we will train KNN, SVM, and RF algorithms on the training data. Each algorithm has its own set of hyperparameters that need to be tuned to achieve optimal performance. Once the algorithms are trained, they are used to classify new data points into either malignant or benign breast cancer.
5. Result: The final step is to evaluate the performance of the algorithms on the testing data. The performance is measured using various metrics such as accuracy, precision, recall, F1-score, and ROC curve. These metrics provide a measure of how well the algorithms are performing in detecting breast cancer. The results can be presented in a report or presentation to highlight the performance of each algorithm and to identify the best algorithm for breast cancer detection.

IV. FUTURE SCOPE

Further research can explore feature selection techniques and dimensionality reduction methods to enhance model performance and efficiency. Additionally, investigating ensemble learning and deep learning approaches, such as convolutional neural networks, can provide valuable insights into breast cancer detection. Integration of multi-modal data, including genomic, imaging, and clinical data, can contribute to the development of more comprehensive models. Real-time prediction and decision support systems can be developed to assist healthcare professionals in diagnosis and treatment planning. In conclusion, this study demonstrates the potential of machine learning algorithms, specifically Random Forest, in breast cancer detection. Further research can focus on advancing these algorithms and incorporating additional data sources to improve the accuracy and clinical applicability of breast cancer diagnosis.
