Hi everyone. Some time ago I learned that cancer can appear in every organ in the human body but it doesn't appear on teeth, nails or hair because they aren't organs.
But then I started thinking: WHY does it only affect organs?
Is my deduction correct? Look:
I think cancer doesn't affect them because tumors are are tissue masses (with altered DNA) and hair, teeth and nails aren't organs so they aren't made up of live tissue masses. On the other hand, organs ARE made up of tissue so this is why cancer affects only organs.
(Sorry about my english, I'm learning biology in spanish and some things might not be translated correctly)
Thank you!

Yes, I believe that's an excellent deduction.
Your English, by the way, is better than that of most native-speakers on this board. You just need to capitalize the names of languages (English, Spanish, French, etc.).
Pretty correct deduction, as it would only make sense you don't get cancer of your hair and nails. I'll have to investigate further on the teeth though. Teeth have both a nerve AND a blood supply, therefore not dead cells.

Carol, every nurse knows the skin is the largest organ.
I am more amazed that you've had every cancer that every poster on this board has ever had, except for, surprisingly prostate!
Looks Good, One Step Further, Is a Malignancy More Probable to Develop In Dividing Cells? E. g. Breast Cells Which Monthly Wax and Wane?
Hello:
Speed dog is right your teeth can get cancer in them from
the blood. It kills the nerves inside of the teeth and turns them
gray but this is only common to people with leukemia as well
as stage 4 cancer patiants that have undergone a lot of chemo.
The bad part is oral surgeons will not remove the teeth if you
have this history as it can cause you to bleed to death while
doing this procedure. I know first hand but you have blood flow
in your nail beds but it delivers air to the calcium in the nails
why you don't get cancer there I don't know I don't think there
is any one doing study on it either mabe they should.
As to the hair the part of our hair that is alive is the folicals as well
as the center of the hair. That is why we frequantly loose our hair
when they do chemo. And our skin is not a organ but we get
skin cancer because it if feed by blood.
I know first hand what it is to have the teeth turn color because
of cancer and my oral surgeon who is the best in LasVegas will
not remove them. They don't hurt but they don't look good either.
I wanted to get false teeth but got told no to dangerous at this
point.
The nerves in the center of your teeth is alive and that is what
keeps them white is healthy teeth.
Sorry speed dog that you never heard of it but it is rare.
I guess I am just a rare type of gal. But I have to be out of
chemo for 6 months to a year for me to safley get false teeth
if they try to remove them now it will spread to my jaw bone.
And my bones are so soft till my teeth break easly as do my
bones. And the bones take a long time to heal for me.
As to the hair I did some reserch back in 2004 cause I wanted
to know why chemo made my hair fall out again. So I went
back to my anatomy books and it showed the hair to the point
of what makes it a living part of our body. Thats why it grows.
The amout of calcium is what makes our nails soft or hard.
and lack of blood flow to the nail bed makes them a yellowish
color frequantly. These are from a anatomy book written in
1994 so there may new stuff out on it now. But the teeth I
know first hand.
Well the cancer spreed. I wish it did not spreed but thats cancer
it will eat what ever good red cells you have.
Sorry to correct the nurse, but teeth do have a blood supply in the pulp and should be "alive" if they are real teeth. Yet you are correct that there doesn't seem to be malignancy involving the pulp of teeth - that I have ever heard about. http://www.enchantedlearning.com/subjects/anatomy/...
Of course a person with leukemia would have malignant cells circulating in the blood vessls of the pulp in teeth, but that would not be considered tooth cancer.
I see that "April" picked up on this too.
To have a malignancy, you need aberrant clones of living cells which do not respond to normal cellular control - they keep dividing eventually creating masses of tumor cells.
Congratulations on your excellent English.

Abstract
Common pathologies of the dental pulp differentiate between acute and chronic inflammatory states caused by caries or dental trauma. Inflammations of the dental pulp as a result of neoplastic alterations are generally considered non-existent. In fact, using the search phrase “dental pulp” combined with “sarcoma”, “carcinoma”, or “neoplasms” in PubMed when using the MeSH search mode yielded no reports on primary malignant neoplasms. However, a hand search yields clinical reports on pulpal tumours that were published over a century ago. In this Essay, the results of a hand search in historic published work are presented. Furthermore, deductive reflections are done on general tumour pathogenesis with respect to specific anatomical prerequisites of the dental pulp. Because of the restricted space in a tooth, tumour expansion will probably lead to the formation of irritation dentine by secondary odontoblasts and, subsequently, to a haemorrhage infarct of the pulp. One hypothesis states that a purported neoplasm of the dental pulp leads to a chronic appositive pulpitis and–sooner or later–will be treated likewise by root-canal treatment or extraction. Further research, including stem-cell studies, is recommended.

teeth hair and nails are dead and have no blood supply,unlike bones
yes, it's something like you have said.
