What is the connection between malignant neoplasms and crabs?

The more common term for malignant neoplasms, cancer, is Latin for crab, and the word "carcinogen," meaning a cancer-causing agent, comes from the Greek word for crab, "karkinos." What is the connection between these two seemingly unrelated things?

Cancer, both the disease and the astronomical constellation, derive from the Latin cancer or cancrum, meaning crab. The astrological sign, of course, is said to resemble a crab and the disease was so named by the ancient Greek physician Galen (129-200 A.D.) who noted the similarity between a certain type of tumor with a crab as well—the swollen veins around the tumor resembling the legs of a crab.

Old English adopted cancer directly from Latin and used it for a variety of spreading sores and ulcers. This early sense survives in the modern word canker. From c.1000 in a manuscript called Læce Boc (Leech Book), collected in Oswald Cockayne’s Leechdoms, Wortcunning, and Starcraft of Early England, Vol. II, 1865:

Gemeng wið þam dustum, clæm on ðone cancer.
(Mix with the dust, smear on the cancer.)

And from Wyclif’s 2 Timothy, 1382:

The word of hem crepith as a kankir

The word was being applied specifically to the disease we today call cancer by the beginning of the 17th century. From Philemon Holland’s translation of Pliny’s Historie of the World:

Cancer is a swelling or sore comming of melancholy bloud, about which the veins appeare of a blacke or swert colour, spread in manner of a Creifish clees.

The astronomical sense of cancer is from the Latin name for the constellation of the crab. The name was known to the Anglo-Saxons, but only as a Latin name and was not assimilated into English until the Middle English period. It appears in Ælfric’s De Temporibus Anni, written c.993, in a list of the constellations of the Zodiac:

Feorða • Cancer • þæt is Crabba
(Fourth, Cancer, that is the crab.)

The Anglicized name appears c.1391 in Chaucer’s Treatise on the Astrolabe:

In this heved of cancer is the grettist declinacioun northward of the sonne...this signe of cancre is clepid the tropik of Somer.
(At this first point (head) of cancer is the greatest declination northward of the sun…this sign of cancer is named the tropic of summer.)

What foods can I eat to stimulate my Thymus Gland?

I read that the Thymus Gland is what makes people grow and is somewhat connected to the sex glands. As the sex glands develop, the Thymus Gland stops working, which is why when a person becomes sexually active (around 22) they stop growing. So what foods can a 24 year old male eat to start the Thymus Gland back up? Maybe not completely but get it going again.

It sure was nice of "Dr. L" to point out that your information was wrong but not give you the correct information, what a cad!
I wish I could answer it for you, but I have no idea.  (+ info)

What happens to an adults immune system if they have their thymus removed?

I am 32 yrs old and about 2 weeks ago I had my thymus removed and it was benign. My question is...What now"?
Am I gonna get sick easily now? Ever since I had the surgery, I have just been feeling extremely tired and muscles sore.

While in childhood the thymus produces T lymphocytes to feed the tissues of the immune system, the thymus reduces in size at puberty from 15-35g down to about 5g. The drop in immunity is not seen in adults with thymusectomy as it is in children. The theory behind this is that the thymus has already produced enough T lymphocytes already.
While having anything surgical and especially something removed does lower immune system, there should not be much of a long term effect.  (+ info)

What is the basis of differing actions of antineoplastic agents on different tissue/neoplasms?

What is the basis for differing tissue- and neoplasm-specificites of antieoplastic chemotherapeutic agents? This doubt arose because considering what the pharmacokinetics of these drugs are it remains to be answered as to why a certain agent would act only in a particular tissue or neoplasm when the mechanisms they employ are so similar, e.g., various alkylating agents in spite having same action act of different tumors with differing degrees of effectiveness. Hope someone answers the question specifically. Useful links to free-text articles would also be highly appreciated. Bye. TC.

If you have thoughts on this subject, you ought to have the initiative to research it yourself.  (+ info)

What is the importance of thymus gland in the body?

I heard that to hit a particular part in between the breasts would activate it and that would cure some illness etc. Is this true?

The thymus is the primary central gland of the lymphatic system. It secretes thymosin, an immunologic hormone, and it's main function is to develop immature T-cells into mature immunocompetent T-cells.

Hitting yourself will only make you chest hurt.

The person above me posted such a long dragged out explanation and never answered your question "What is the importance of thymus gland in the body?".  (+ info)

If the thymus stops working after puberty where do we store the tcells?

Also if we have a dysfunction with the thymus what would be the signs or symptoms ....and if it turns to connective tissue as we get older how can we have the S&S

Good question... First off, those t cells originated in the bone marrow, then they migrate to the thymus where they get an "education" After t cells that would attack the body are weeded out they then migrate to lymphatic tissue throughout the body -spleen, lymph nodes, pyers patches of intestines, etc. and wait to be presented antigens from invading microbes. By the time puberty hits most of this has occurred and the thymus isnt needed. To complicate things more, there are two major types of T cells: cytotoxic T cells and T helper -type cells.
The cytotoxic cells are the ones that go around and kill infected cells while the Thelpers modulate a big part of the immune system.
Hope this helps...  (+ info)

My friend was diagnosed with myasthenia gravis,he needs surgery to take out his thymus, what is thymus?

Where is the thymus, first time I've heard of this condition(myasthenia gravis),and if he will undergo surgery,how long does the surgery takes?

Thymus is located in the middle of you upper chest. Is part of the immune system. Mainly functional after birth for a short time until the infant starts to develop their own immunity. The thymus shrinks down to very little after that.

How long of surgery? Depends on the surgeon and if everything goes as planned.  (+ info)

What vein is located underneath the fetal pig’s bottom jaw and runs alongside the thymus?

Not a cancer question.  (+ info)

Does anyone know any enocrine system diseases/disorders of the Thymus Gland?

I'm doing a poster on the thymus gland, and i need to find two good diseases/disorders that are caused by the thymus gland. I found some but they really dont make any sense. Does anyone know? or know a site i could go to?
