Abstract

Breast Cancer and its types

Author(s): Tabitha Davis

The breast is made up of a variety of tissues that range from very fatty to quite dense. A network of lobes exists within this tissue. Each lobe is made up of lobules, which are tiny tube-like structures that contain milk glands. Milk is transported from the lobes to the nipple by tiny ducts that connect the glands, lobules, and lobes. The nipple is in the centre of the areola, which is the darker area surrounding the nipple. The breast also has blood and lymph channels running through it. The cells are nourished by blood. The lymphatic system removes waste items from the body. Lymph nodes, which are little bean-shaped organs that help fight infection, are connected to lymph vessels. Lymph nodes are found in several locations across the body, including the neck, groyne, and belly. The lymph nodes around the breast, such as the lymph nodes under the arm, are referred to as regional lymph nodes of the breast. When healthy cells in the breast alter and expand out of control, they create a tumour, which is a mass or sheet of cells. Tumors can be malignant or noncancerous. A malignant tumour is one that has the potential to grow and spread to other regions of the body. The term "benign tumour" refers to a tumour that can develop but not spread. Breast cancer spreads when it invades nearby organs or other regions of the body, or when breast cancer cells travel through blood arteries and lymph vessels to other parts of the body. This is referred as as a metastasis.
