Anatomy & Functions
Throughout these videos, as you learn about breast cancer, we will repeatedly reference the anatomy of the breast. Understanding the different parts and functions will help you better grasp the details of breast cancer.
The female breast is mostly made up of a collection of fat cells called adipose tissue. This tissue extends from the collarbone down to the underarm and across to the middle of the ribcage.
Lobes, Lobules, and Milk Ducts
There are also areas called lobes, lobules, and milk ducts. A healthy female breast is made up of 12–20 sections called lobes. Each of these lobes is made up of many smaller lobules, the gland that produces milk in nursing women. Both the lobes and lobules are connected by milk ducts, which act as stems or tubes to carry the milk to the nipple.
Also within the adipose tissue, is a network of ligaments, fibrous connective tissue, nerves, lymph vessels, lymph nodes, and blood vessels.
The lymph system, which is part of the immune system, is a network of lymph vessels and lymph nodes running throughout the entire body. Similar to how the blood circulatory system distributes elements throughout the body, the lymph system transports disease-fighting cells and fluids. Clusters of bean-shaped lymph nodes are fixed in areas throughout the lymph system; they act as filters by carrying abnormal cells away from healthy tissue.
In this chapter we looked at the anatomy of the breast, focusing on the milk ducts, lobes, lobules, lymph system, and lymph nodes.

I thought I felt a lump in my armpit last month. I mentioned it to my Oncology people as I just happened to have a 6-month followup appointment. She felt it and said it was just "excess fat". It's odd as it is only on the side I had my mastectomy on and not the other one, too. She didn't seem...

A plastic surgeon can during reconstruction. If she chooses no reconstruction the PS can still deal with it.Comment 0

That would be a great question for your oncologist. It seems reasonable it would be ok but not being a doctor, they should answer that for you. Port's make chemo treatments much easier.Comment 2
The port is usually placed on the non-cancerous side. What has your Onc said about this?1 comment 0

Put on those big girl panties and fight like hell. Hang in there darlin', you can do this.
Take care, SharonComment 2
Yep. Hang in there. Read and eat good stuff and don't add to your receptors. I think that's about all we can do. We do the best we can.
Wishing you a good teamComment 2
