Breast cancer is classified into different types based on how the cells look under a microscope. Most breast cancers are carcinomas, a type of cancer that begins in the linings of most organs. Ductal carcinoma in situ DCIS is characterized by cancerous cells that are confined to the lining of the milk ducts and have not spread through the duct walls into surrounding breast tissue. DCIS is the most common type of noninvasive breast cancer, with about 60, new cases diagnosed in the United States each year. About one in every five new breast cancer cases is ductal carcinoma in situ.
Tubular carcinoma: Symptoms, causes, treatment, and survival rates
Tubular breast cancer is a type of invasive ductal carcinoma. Screening mammography often detects tubular breast cancer as a small mass , irregular in shape with spiculated margins. So, the distinguishing feature is the visual appearance of the cells under a microscope. In this case, the cancer cells resemble tiny tubes that are well differentiated, meaning the cells are more like normal cells than poorly-defined ones. I just want to let you know that I have created a newer version of this page with more up-to-date material on Tubular Carcinoma of the breast.
Although breast cancer is often referred to as one disease, there are many different types of breast cancer. Breast cancers differ in other ways. They can be non-invasive or invasive. Tumor cells can vary in location milk ducts or lobules and how they look under a microscope.
Like other types of invasive ductal cancer, tubular breast cancer begins in the milk duct of the breast before spreading to the tissues around the duct. When the cells of a tubular breast tumor are examined under a microscope, they look like tubes, which gives this cancer its name. Tubular breast cancer cells tend to behave less aggressively than more typical kinds of invasive ductal cancers.
