what are the four types of breast cancer

Release time ：Nov-09,2024

Breast cancer is a complex disease that can generally be categorized into four main types: non-invasive carcinoma, invasive ductal carcinoma, invasive lobular carcinoma, and other rare types of breast cancer. These classifications are based on the tumor's origin, growth pattern, and cellular characteristics.

Firstly, non-invasive carcinoma, also referred to as carcinoma in situ, represents the least aggressive form of breast cancer. In this type, tumor cells are confined to the milk ducts or lobules and have not yet infiltrated the surrounding tissues. Secondly, invasive ductal carcinoma is the most prevalent form of breast cancer, constituting approximately 80% of cases. It is characterized by the spread of cancer cells from the milk ducts into the adjacent tissues. Thirdly, invasive lobular carcinoma accounts for about 10% of breast cancer cases and is distinguished by the origination of cancer cells in the lobules with subsequent spread to surrounding tissues. Lastly, other rare types of breast cancer encompass mucinous carcinoma, inflammatory breast cancer, and papillary carcinoma, among others. These types are less commonly known due to their lower incidence rates.

For the prevention and early detection of breast cancer, it is advised that women conduct regular self-examinations of their breasts and adhere to medical recommendations for breast cancer screening. Should any abnormalities be detected, it is crucial to seek medical attention promptly and obtain a professional diagnosis and treatment. Throughout the treatment process, patients must strictly comply with medical instructions and avoid self-medicating to ensure the efficacy of the treatment and maintain overall health.
