Now melanoma also might be one that you have
noted with a little star we first started this video series
because it begins in the cells, it become melanocytes.
This is what you see most often as skin cancer.
People who were exposed to a lot of sun or
tanning beds tend to be at higher risk for this.
So melanoma starts in the melanocytes of your skin.
So melanocytes are those
specialized cells that make melanin.
Now we all want that beautiful brown skin but we can
actually really do damage to your skin in the long-term.
So most of the melanomas form on other
skin but can also form on other pigmented tissue
like your eye, that to me is ugh, that really weirds me out
but most often you see melanoma ,it will start on the skin.
Brain and spinal cord tumors are never a good idea, right?
There are different types of brain and
spinal cord tumors and they're named
based on the type of cell in which they're formed.
So an astrocytic tumor start in me astrocytes,
those are those star-shaped brain cells.
Brain tumors can be benign or malignant but
this is one of the worst places to have a tumor
because even a benign
brain tumor can be dangerous.
A benign brain tumor causes extra
pressure inside your head, right?
You're intracranial pressure elevate to the point
because you got that extra mass of tissue in there.
Your intracranial pressure could elevate to the point that
you really start to notice some impairment of your function
or even worse it could proceed to herniation.
So this is the worst case in my opinion
that you'd want to have even a benign tumor.
Now there's some other less
common miscellaneous tumors.
There's germ cell tumors, those start
in the cells that becomes sperm or egg
and they could occur almost anywhere in
the body and become benign or malignant.
Neuroendocrine tumors, okay
look at that neuro- and -endocrine
so that gives you clue where these come from.
They come from cells that
release hormones into the blood.
So tumors may make higher
than normal levels of hormone.
Okay, we are very delicate creatures, right?
We have a very small window of
balance for hormones in our bloodstream
so if you have a neuroendocrine tumor
and it starts making higher levels of hormones,
all kinds of things are gonna
be out of whack in your body.
So even if it's a benign tumor, this is
still gonna wreak havoc on your body.
Neuroendocrine tumors can be benign or
malignant but again, you don't want either one of those.
Now, carcinoid tumors or another type of
neuroendocrine tumor, they're slow-growing tumors.
Usually found in the GI system, usually the rectum or
the small intestine are the most common places for it.
Now this could also spread
to the liver or other sites
and it might secrete serotonin or prostaglandins
which can cause carcinoid syndrome.
