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.)

How does nervousness and stress cause someone to have a duodenal ulcer?
Dave is under a lot of stress at his job and at home. He begins to feel disconfort and a burning sensation in his abdomen following a meal. After consulting a doctor, he finds that he has developed a duodenal ulcer. He does not understand how being nervous would cause the ulcer and asks us to explan.
When the body or mind is under stress it can stimulate the stomach to produce more acid - after a while this eats through the mucous lining and causes an ulcer. I thought that most ulcers were caused by a bacteria - heliobacter pylorus - has he been checked for that? (+ info
What are the symptoms of duodenal ulcer or any ulcer in the digestive system?
What are the symptoms of duodenal ulcer or any ulcer in the digestive system?
plz help fast...
There are many signs and symptoms from either or both of these. From bloody or black colored stool to constipation that isn't relieved after 2-3 days. The duodenal is a part of the colon and the symptoms are usually different from a stomach ulcer. The stomach ulcer can still have you bringing up blood or having it go through the entire colon, then there can be allot of gas that isn't relieved, to not wanting to eat at all. You can also vomit blood from an ulcer. Since the colon is about 25 feet of a turning open tunnel it wraps around and then up then around until it finally turns down toward the rectum and anus. If you suspect any problems with any part of the digestive system which includes the esophagus, stomach, liver,pancreas and gallbladder and then the appendix until finally the colon and down try going to a GI doctor for a complete exam of this system. As you get older it's a great idea to have your digestive system checked for any problems including polyps and or cancer. Good luck and God Bless (+ 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
How long does it take to heal a duodenal ulcer?
I have been prescribed Lanzoprozole. How long should it take for the aching pain to go and the ulcer to heal? I have not yet had the H pylori test (awaiting breath test). If I have the bug and it is not found, will my symptoms not improve on the PPI's alone?
PPIs are usually given from 4 to 8 weeks.
If symptoms persist and endoscopy is often performed (a look-see down a fine tube with a light at the end).
H pylori can be detected from a blood, breath, faecal test or from a biopsy taken during endoscopy.
If H pylori present the main part of treatment is to clear the infection and a course of 2 antibiotics plus the PPI are given.
Unless treated the helicobacter pylori is there for life.
What is the difference between a peptic, gastric and duodenal ulcer and what are some natural ways to deal?
the discomfort of them? Also, what organ is located about an inch above the navel and to my right (would be an observers left)?
Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE. It is often associated with HELICOBACTER PYLORI infection or consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
1)Recurrent abdominal pain - dull and burning type pain usually located in epigastric area (area between belly button and rib cage)
2)Abdominal pain after food
3)Abdominal pain at night
4)Blood in vomit
The list of conventional treatments are;
Symptomatic relief: antacid preparations
Anti-acid medications: "Proton-Pump" inhibitors (eg omeprazole, lansoprazole), H2 antagonists (eg ranitidine, cimetidine)
Eradication of Helicobacter pylori infection: oral antibiotics, proton pump inhibitor
Avoidance of NSAID medications (aspirin, ibuprofen (Nurofen, Brufen etc)
Surgery - partial gastrectomy
A peptic ulcer is a sore on the lining of the stomach or duodenum, which is the beginning of the small intestine.
List of causes or underlying conditions;
1)Helicobacter pylori bacteria
2)Excess stomach acid
5)GERD - a cause of esophageal ulcers
Treatments for gastrointestinal bleeding:
Emergency treatment - if gastrointestinal bleeding from a bleeding ulcer is suspected
See also treatment of anemia - because anemia can result from gastrointestinal bleeding and its blood loss.
Discontinue causative medications - for NSAIDs and other secondary causes
Antibiotics - mainly for the treatment of H Pylori infections
Natural method of treatment;
Avoid ulcer triggering foods
Avoid spicy food
Avoid fatty foods
A peptic ulcer located in the DUODENUM
Some of the possible causes of Duodenal ulcer include:
Excess stomach acid
Helicobacter pylori bacteria
Mostly similar to symptoms of peptic ulcers
Abdominal pain after meals
Pain below the ribs
You must always seek professional medical advice about any treatment or change in treatment plans. (+ info
Rantidine is administered to patients with duodenal ulcers for which of these reasons?
1. To decrease the secretion of gastric acid
2. To relax the smooth muscle of the intestine
3. To neutralize excess hydrochloric acid
I believe number 2
It is ranitidine not rantidine - it blocks the release of stomach acid.
The answer is #1.
Very easy to look this up online http://www.drugs.com/ranitidine.html (+ info
Is a peptic ulcer and duodenal ulcer the same thing?
Im doing a project and my assigned topic was petic / doudenal ulcers. Are these two type of ulcers the same?
A peptic ulcer is a sore in the lining of your stomach or duodenum. The duodenum is the first part of your small intestine. A peptic ulcer in the stomach is called a gastric ulcer. One that is in the duodenum is called a duodenal ulcer. A peptic ulcer also may develop just above your stomach in the esophagus, the tube that connects the mouth to the stomach. But most peptic ulcers develop in the stomach or duodenum. (+ info
How is a duodenal ulcer different from a stomach ulcer?
They fall under the same umbrella term "peptic ulcer"
The difference is where they're located. One is in the stomach, where as the other is in the first part of the small intestine (the duodenum).
There are also some subtle differences
- duodenal ulcers are for the most part relatively benign and treated, whereas stomach ulcers can have a slightly higher risk of being cancerous, so they're usually biopsied
-duodenal ulcers tend to give pains when hungry, whereas stomach ulcers tend to give pain when food is in the stomach (and there's acid secretion). (+ info
Why are duodenal ulcers more common than gastric ulcers?
How peptic ulcers are formed:
"H. pylori weakens the protective mucous coating of the stomach and duodenum, which allows acid to get through to the sensitive lining beneath. Both the acid and the bacteria irritate the lining and cause a sore, or ulcer."
A couple of websites have stated stastics that duodenal ulcers more common than gastric ulcers but hvaen't stated why.
I don't know but my husband has them. He was hospitalized for 4 days last month cuz they were bleeding. (+ info
