The second-leading cause of death for women is breast cancer. Consequently, a precise early diagnosis is essential. With the rapid development of artificial intelligence, computer-aided diagnosis can efficiently assist radiologists in diagnosing breast problems. Mammography images, breast thermal images, and breast ultrasound images are the three ways to diagnose breast cancer. The paper will discuss some recent developments in machine learning and deep learning in three different breast cancer diagnosis methods. The three components of conventional machine learning methods are image preprocessing, segmentation, feature extraction, and image classification. Deep learning includes convolutional neural networks, transfer learning, and other methods. Additionally, the benefits and drawbacks of different methods are thoroughly contrasted. Finally, we also provide a summary of the challenges and potential futures for breast cancer diagnosis.

Since the mid and late 19th century, people have paid more and more attention to the ecological environment, and environmental awareness and behaviour have been gradually strengthened. The global environmental protection movement is rising daily, and environmental protection will become the focus of human attention in the 21st century. Accelerate the establishment and improvement of the system and mechanism of land and space development, resource conservation and utilisation, and ecological preservation of the environment in the system of ecological civilisation, and promote the formation of a new pattern of harmonious development between man and nature and modernisation. Although China has formulated policies and regulations on environmental protection in outdoor sports development, environmental protection is grim due to problems such as insufficient government supervision, weak public awareness of environmental protection, and relatively backward environmental protection concepts and management methods. During the visit, outdoor sports lovers and club leaders were interviewed. In this context, with the continuous development of outdoor mountain sports driven by the improvement of people’s pursuit of life, there began to be contradictions between outdoor mountain sports and the ecological preservation of the environment, which also became the cause of the author’s concern and research.
