The breast is made up of lobes and ducts. Each breast has 15 to 20 sections called lobes. Each lobe has many smaller sections called lobules. Lobules end in dozens of tiny bulbs that can make milk. The lobes, lobules, and bulbs are linked by thin tubes called ducts.
Invasive Ductal Carcinoma (IDC) Breast Cancer: Johns Hopkins Breast Center
Breast cancers that have spread into surrounding breast tissue are known as invasive breast cancer. Most breast cancers are invasive, but there are different types of invasive breast cancer. The two most common are invasive ductal carcinoma and invasive lobular carcinoma. Inflammatory breast cancer and triple negative breast cancer are also types of invasive breast cancer. This is the most common type of breast cancer. About 8 in 10 invasive breast cancers are invasive or infiltrating ductal carcinomas IDC.
Breast Cancer Survival Rates for all types of breast cancers
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.
Analysis of a multi-institutional cohort of patients with lobular breast cancer provides key insights into prognosis. An analysis of the largest recorded cohort of patients with invasive lobular breast cancer ILC demonstrates that outcomes are significantly worse when compared with invasive ductal breast cancer IDC , highlighting a significant need for more research and clinical trials on patients with ILC. This clinical and pathological, multi-institutional, epidemiological cohort study provides prognostic insights critical to future research and clinical trials and was presented at the San Antonio Breast Cancer Symposium.
