Which of the following is a common type of breast cancer?

• A. Ductal carcinoma in situ (DCIS)
• B. Melanoma
• C. Non-Hodgkin lymphoma
• D. Hodgkin lymphoma

Answer: (A)

Ductal carcinoma in situ (DCIS) is indeed a common type of breast cancer. It is characterized as a non-invasive form of breast cancer where abnormal cells are found in the lining of breast ducts but have not invaded surrounding breast tissue. This means it is generally considered to be at an earlier stage of cancer development, and although it is not life-threatening, it can increase the risk of developing invasive breast cancer later on. In contrast, the other options listed are types of cancers that do not specifically pertain to breast tissue. Melanoma is a form of skin cancer that develops in the pigment-producing melanocytes. Non-Hodgkin lymphoma and Hodgkin lymphoma are types of cancers that affect the lymphatic system, which plays a role in the immune system but is unrelated to breast cancer. Therefore, among the choices provided, ductal carcinoma in situ is the only one that is a common type directly associated with breast cancer.
