Breast Cancer 101: The Background

Friday, October 05, 2012

Hello, lovelies~ As we all welcome October, I'm going to do a brief series of post that will be filled with facts about breast cancer. So, without further ado, let's get started with the first post. 

Before I start with the cancer things and their treatments and whatnot, I'll start with the basic knowledge about breasts. Yes, you read that right. Breasts. Bosoms. Boobs, if you wanna be immature about it, lol. I want to start by explaining the anatomy of our breasts.

Anatomy of normal breasts

Calm down. I'm not gonna use real life, dissected, bloody pictures of a human breast. Instead, I'll just a friendly cartoon picture that looks cute and nothing gross or gory. As you can see from the picture below, the breast consisted of 
  • Muscles
  • Blood vessels (d-uh)
  • Lymph nodes
  • Fatty tissues
  • Lobules, which produces milk at each end.
  • Ducts 
  • A nipple

Being in the center, the nipple is surrounded by lobules that kinda looks like a wheel, doesn't it? You know with the spokes being the lobules and the nipple being the center? ^_^


Statistics

I know, I know, you're probably bored with this part. I don't really like statistics myself, but it's important, yo! It gives you a picture of the effect of breast cancer in most populations. So, just stay with me, yeah? I'll make it as painless as ever.

The data is taken from Cancer.org, it displays the cases of breast cancer based on sex, age, and race.

  • Sex

    • In women, breast cancer is more common (excluding skin cancer) compared to other type of cancer. 
    • Picture this, if there are three women being diagnosed for cancer, 1 out of the three will be diagnosed with breast cancer. 

  • Age

    • The breast cancer incidence or cases usually increases with age. Almost 95% of new cases is found in women aged 40 years and older
    • During 2004-2008, women aged 20-24 years old has the lowest incidence rate, the highest is women aged 75-79 years old. However, it is still important to have examinations as preventions, girls! I'll cover that in another post. 

  • Race 

    • The highest incidence of breast cancer is in non Hispanic white women compared to other races. For details, you can check out the graph below. 

Types of cancer

Let's get down to business. There are various type of breast cancer, but what differentiates them is where they are located inside the breast tissues. Remember the picture from the anatomy of the breasts? There are lobules and ducts, hence the types of breast cancer. So, here are the types of breast cancer
  • Lobular carcinoma is a type of breast cancer that starts in the lobules of the breast tissue.
  • Ductal carcinoma is a type of breast cancer that starts in... Right! the ducts found in the breast tissue. This is most common breast cancer type. 

These types of breast cancer is further divided into either invasive or noninvasive. 
  • Invasive is a condition where the cancer has spread from the ducts or lobules to other parts of the breast tissue.
  • Noninvasive is a condition where the cancer has not spread. In other words, it just stays put in its original place. This condition is also known as 'in situ'.

So, a lobular carcinoma can be either invasive or noninvasive. Get it?

That wraps it up for the background of breast cancer. The next post will discuss further about the causes of breast cancer and potential risk factors surrounding it. I hope you guys have a great day and I'll talk to you later~

  4. This is a very nice post. Is October breast cancer awareness month? I wansn't aware. Anyway, one advice our professors tell us is to encourage our friends to do breast self exam (BSE) yearly, or monthly if you're OC about it. So you get the cancer early on. Hope you post something about BSE. :)
