Breast cancer is a type of cancer that begins in the cells of the breast. It can occur in both men and women but is more common in women. Breast cancer can develop in different parts of the breast, including the tubes that carry milk to the nipple or the lobules that produce milk. The exact cause of breast cancer is not completely understood, but factors such as genetics, hormone situations, and lifestyle choices can increase the threat of developing the disease. Common symptoms of breast cancer include a lump or mass in the breast, changes in the size or shape of the breast, and nipple discharge. Early detection and regular screening are pivotal in perfecting outcomes for patients with breast cancer. 

Why Breast Cancer Occurs

Breast cancer occurs when normal cells in the breast tissue suffer gene mutations that cause them to grow and multiply in an uncontrolled manner. These mutations can be caused by a variety of factors, including genetic predispositions, hormonal influences, lifestyle choices, and environmental exposures. The formation process of breast cancer generally begins with a single mutated cell that continues to divide and proliferate, forming a mass of abnormal cells known as a tumor. Over time, these cancerous cells may foray into nearby tissues and ultimately spread to other areas of the body through the lymphatic system or bloodstream, and this process is called metastasis. 

Some crucial factors can contribute to the development of breast cancer, including gene mutations, hormonal influences, lifestyle choices, and environmental exposures. That is to say, the mutations in certain genes (such as BRCA1 & BRCA2) and the hormone changes can increase the risk of breast cancer to some extent. Hormones like estrogen and progesterone play a significant part in breast cancer development. Women with higher levels of these hormones, either naturally or because of hormone therapy, are at an increased risk of developing the disease. Not only that, improper lifestyle can also change hormone levels. Other factors such as obesity, lack of physical activities, smoking, and inordinate alcohol consumption have been directly linked to a greater risk of breast cancer. Exposure to unhealthy surroundings (e.g., some specific chemicals and radiation) can also accelerate cancer formation. Overall, breast cancer is a complex disease that can be affected by multiple factors. Early detection through regular screening and genetic testing, as well as lifestyle modifications to reduce threat factors, can help to prevent and treat breast cancer effectively.

Related Therapy Techniques and Methods

Due to the complexity of breast cancer’s formation, it requires a multidisciplinary approach for effective treatment. The therapy options for breast cancer depend on various factors such as the stage of the cancer, the type of the cancer, the patient’s overall health, and particular preferences. At present, some commonly used technologies for breast cancer treatment include surgery, chemotherapy, radiation therapy, hormone therapy, targeted therapy, and immunotherapy. To deeply understand the biological characteristics of breast cancer, some CRO companies also offer modeling services (e.g., breast cancer animal models) for research.

Particularly, immunotherapy can be used alone or in combination with other treatments like chemotherapy or radiation therapy. For example, the development of breast cancer therapeutic antibodies is usually linked with targeted therapy for the complexity of tumor cells. Immunotherapy is a promising approach in treating a variety of cancers and is continuing to be studied in traits to ameliorate its effectiveness and reduce side effects.

New Research Trends

Breast cancer research is a constantly evolving field, with new explorations emerging and our understanding of the disease heightening. Besides immunotherapy, some of the new trends and prospects include personalized medicine, early detection & forestallment, and survivorship & quality of life.

With ongoing advancements in technology and a growing understanding of the molecular and genetic basis of the disease, researchers are optimistic about the development of further effective and individualized therapies for breast cancer. Additionally, more and more attention on prevention and early discovery is helping to ameliorate healthcare issues and reduce the burden on the healthcare system. By using technical and data analytics tools, healthcare providers can better identify and address health issues before they escalate, eventually leading to preferable patient care and overall population health. To sum up, the field of breast cancer research holds great prospects for continued advancements in diagnosis, treatment, and survivorship.
