Learning about cancer

The first thing I wanted to understand was what part of the breast was suseptible to cancer. I checked out a few different websites, one being The Canadian National Cancer Institute‘s website ((go figure)) and so far I understand that the breast is made up of different sections1 which contain smaller sections2. Each of these smaller sections3 contain organs that produce the milk that babies love. Mostly, the breast is made up of fat, and these ograns they’ve4 decided to call lobes and lobules. I didn’t mention nipples because, well… we all know they’re there. They’re the ‘duh’ part.

But the important part of the breast to keep an eye on when checking for cancer, is the lymph vessels. Apparently these lead to lymph nodes5 which carry bacteria, cancer cells and other harmful substances. These lymph nodes exist all over our body.

Now, I think even I remember learning in high school biology that our cells are constantly renewing in our body6. Tumors are formed when the system of cell renewal goes astray, as in when the new cells form before the old cells have had a chance to die and the old cells don’t die like they should. But as I’ve learnt from the TV dramas, not all tumours are cancerous. Some tumours can just be extra tissue… some… aren’t so happy7.

What was easy to understand was that unless caught and treated early, breast cancer can spread almost any other part of the body and that the most common parts they spread to are the bones, liver, lungs, and brain.

So how does it spread? What I first needed to understand was that the lympathic system is something similar to the nervous system or our veins and arteries but instead of carrying nervous cells, or blood it carries a fluid called lymph through our system. This yellowish, watery fluid containing white blood cells8, red blood cells and protein is important to our immune system health. Wisegeek compared lymph to a milkman who replenishes us with nutrients9 and takes away the empty bottles. Of course, this is one milkman who won’t sleep with your wife10.

Cancer can also spread through our blood stream; the not so happy11 tumours previously mentioned can break off of where they had originally grown and travel through the bloodstream12 until they find a suitable new home13.

Cancer can also ‘invade’ the healthy tissue surrounding it. This type of Cancer is usually ‘easier’ to get rid of if caught early enough and if all infected tissue is removed accurately. But, its said that it’s not a guarantee that the same type of cancer won’t form again in another part of the body and it would be completely unrelated to the first one.

Lastly14, there is apparently the rare instance that cancer can form as a result of something happening during a biopsy. A biopsy is the surgery performed to get rid of a malignant tumour… and sometimes, the needle being used to remove the tumour can drip onto other healthy organs and infect said organ15.

So! That’s what cancer is… and that’s how it spreads through our body. I hope you learnt something today, because I certainly did.

Have you gone pink for October?

  1. the article called them lobes []
  2. they called these lobules []
  3. so the lobules []
  4. the scientist geeks []
  5. that strangely look like a lima bean []
  6. that’s why we shed skin, and etc. If you didn’t know that, I’m sorry to be the one to tell you but we shed too… just like our cats and dogs []
  7. these are called malignant tumours []
  8. called lymphocytes — I know boring Jargon right? []
  9. like those found in milk []
  10. woh woh woh []
  11. malignant []
  12. mostly through the veins as opposed to the arteries []
  13. damn bastards []
  14. but not least-ly… []
  15. WHAT?!! []

responses to “Learning about cancer” 13

  1. @Beeker: It was my pleasure! I had a lot to learn myself! There’ll be more to come for the rest of the month!

  2. Thanks for the information! I think women and men need to be aware of breast cancer. I was surprised to find out recently that breast cancer is something all women need to be concerned about and not just women over 35.

  3. @Haley: Thanks 🙂 I’m glad it’s useful to you guys as well. I’m glad to hear your friend survived it!

    @mspennylane: Wow! Another survivor; its always great to hear success stories (especially since someone close to me just lost someone to cancer). Glad this post was useful to you as well 🙂

  4. Thanks for the post Reg, it is helpful to know the facts. I actually had a boyfriend who had cancer (Hodgkins lymphoma) and it makes me more aware of the disease though I still don’t really like reading that much about it. But on a positive note he is absolutely fine now, recovered about 4/5 years ago and we’re still friends. I think there are so many mixed messages about cancer, and that there is a lot more to understand, so thanks for the information 🙂

  5. Good information. Thanks for making us all think about this information. It’s important.

    I remember when a friend had a malignant tumor removed, they also took the nearby lymph node to see if the cancer had spread there. Fortunately, it hadn’t. The prognosis is so much better when the cancer hasn’t reached the lymph system yet. BTW, the friend is a survivor.

  6. @trench: Wow that *is* too much. Everything in moderation! I like to learn about things but I wouldn’t go that far. Though I used to remember being a complete germaphobe who would wash her hards after touching anything… yeah it was pretty bad. I hope she smartens up soon – she’s going to get herself sent to the whitejacket place. LOL

    @Lyndi: I’m glad it was of some use to you, it helped me just writing about it!

  7. Thanks for the nice explanation without all those big medical words. Self-examination stays extremely important. Thanks again.

  8. Its good to be aware of it, but I have this friend who’s obsessed with it. So much so its hard to live her daily life without going crazy when someone lights up beside her or uses her cell phone too long.

    Good post though reg! haha. Very informative.
