When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. The pathologist sends your doctor a report that gives a diagnosis for each sample taken. Information in this report will be used to help manage your care. The questions and answers that follow are meant to help you understand medical language you might find in the pathology report from a breast biopsy , such as a needle biopsy or an excision biopsy. In a needle biopsy, a needle is used to remove a sample of an abnormal area. An excision biopsy removes the entire abnormal area, often with some of the surrounding normal tissue.

Grading for non-invasive breast cancers such as ductal carcinoma in situ (DCIS) is different, and is defined as low, medium or high grade rather than 1, 2, or 3.

What grade is the breast cancer? What size is the breast cancer? Cancer cells are given a grade according to how different they are to normal breast cells and how quickly they are growing. Generally, people with grade 3 invasive breast cancers are more likely to be offered chemotherapy, to help destroy any cancer cells that may have spread as a result of the cancer being faster growing. There are also three grades of ductal carcinoma in situ DCIS , which are usually referred to as low, intermediate and high. Back to top. The size of the breast cancer is measured at its widest point, usually in millimetres mm.

Breast cancer affects one in every eight American woman. If detected and treated early, it is highly curable. Seattle Cancer Care Alliance SCCA offers mammography and other services to detect breast cancer early as well as comprehensive treatment from a team of breast cancer experts. Breast cancer develops when cells in the breast divide and grow without their normal controls. Instead they grow into a tumor, which may invade nearby tissue and spread to other organs. In situ breast cancer is only in the milk ducts and lobules milk-producing glands.

Grades and stages

Stages 0 & 1

The stage of cancer indicates the size of the tumor of abnormal cells and whether or not those cells are contained to the place of origin. The most common type of breast cancer is ductal carcinoma in situ DCIS , indicating the cancer cell growth starts in the milk ducts. Stage 0 breast cancer,ductal carcinoma in situ DCIS is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct. In Stage 0 breast cancer, the atypical cells have not spread outside of the ducts or lobules into the surrounding breast tissue. Lobular carcinoma in situ at Stage 0 generally is not considered cancer.

IDC is the most common form of breast cancer, representing 80 percent of all breast cancer diagnoses. As with any breast cancer, there may be no signs or symptoms. A mammogram may reveal a suspicious mass, which will lead to further testing. A woman may also find a lump or mass during a breast self-exam. The following are possible signs of breast cancer and should immediately be reported to your physician for further evaluation:. At the Johns Hopkins Breast Center, we know how quickly patients want results from a biopsy or scan if there is a suspicion of breast cancer. We follow strict guidelines for biopsies and pathology reports.

Invasive Ductal Carcinoma Stages

Staging and grading usually happens after your breast tumour has been removed by surgery, as a pathologist will need to test the tissue in a laboratory and examine it under a microscope. The grade of a tumour indicates what the cells look like and gives an idea of how quickly the cancer may grow and spread. Tumours are graded between 1 and 3. Grade 1 the cancer cells look small and uniform like normal cells, and are usually slow-growing compared to other grades of breast cancer. Grade 2 the cancer cells are slightly bigger than normal cells, varying in shape and are growing faster than normal cells. Grade 3 the cancer cells look different to normal cells, and are usually faster-growing than normal cells.
