Changes in how people live, eat, and interact in society have made cancer more widespread. Among various types of cancer, breast cancer is the most common in women globally and ranks second overall. In 2018 alone, there were over 2 million new cases of breast cancer worldwide, as reported by the World Cancer Research Fund. Unfortunately, women who have had breast cancer are at a higher risk of developing mastitis, especially during breastfeeding. The increasing number of breast cancer cases globally is a major factor contributing to the growth of the global mastitis market. For instance, in the United States, the Breast Cancer Research Foundation estimated that 266,120 new cases of invasive breast cancer were diagnosed in women in 2018, making it the most common cancer among American women, second only to skin cancer. The impact of breast cancer is not limited to the United States. In the United Kingdom, breast cancer was responsible for approximately 11,563 deaths in 2016, according to Cancer Research UK. On a global scale, Belgium had the highest rate of breast cancer in women in 2017, with a rate of 113.2 per 10,000 breast cancer cases, as reported by the World Cancer Research Fund International. This trend of increasing breast cancer rates worldwide is directly linked to a rise in mastitis cases. As more women experience breast cancer, the occurrences of mastitis, an inflammation of the breast tissue often associated with breastfeeding, are also on the rise. The connection between breast cancer and mastitis emphasizes the need for effective solutions and treatments for mastitis. Understanding the global trends in breast cancer and its consequences, including mastitis, is crucial for healthcare professionals and researchers working to address the challenges posed by these conditions. The increasing prevalence of breast cancer globally underscores the importance of ongoing efforts to develop better diagnostic tools, preventive measures, and treatment options for mastitis and related complications.
