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.)

should i see an allergist if i keep getting a bronchial infection?
I have had a cold for few weeks and it never totally goes away, it comes back and now I have a bronchial infection. This is not the first time this has happened. I am also trying to see how I can build my immune system. Im not sure if its weakened, but I know a cold should not linger, start to go away, then relapse. Any info is welcomed.

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.
