A category of cytology interpretation which corresponds to “suspicious of malignancy”, based on the NHSBSP (UK) guidelines for cytology reporting of aspiration cytology of breast lesions.

A plastic explosive which is one-third more powerful by weight than TNT. When C4 is detonated, the explosive is converted into gas which creates a pressure (shock) wave that demolishes the target by cutting, breaching or cratering.

C-4 is made from around 90pc research department explosive (RDX), first created in Britain, and a plasticiser giving it a putty-like quality.
Last night, explosives expert Dr Sidney Alford said the C-4 in the man's shoes might not have been enough to blow up the whole aircraft.
He said: "If he was sitting in an aisle seat with his soles packed with C-4, he would have killed himself and killed or injured people around him.
Even with the thickest soles on, the amount of C-4 couldn't have been that much.
Simultaneously with the entering into of the Share Exchange Agreement, DataWave, C-4 and Inprimis entered into a non-binding Letter of Intent under which DataWave, C-4 and Inprimis agree in principle to the Plan of Arrangement.
Under the Share Exchange Agreement, C-4 and another holder of DataWave's shares which together hold an aggregate of 17,759,000 common shares of DataWave representing 40.
Because Inprimis' Articles of Incorporation do not presently authorize a sufficient number of its common shares to effect the exchange, Inprimis will, immediately upon the closing of the share exchange, issue 11,400,000 shares (representing 43% of the new shares) to C-4 and the other transferor and will give to C4 an interest-free subordinated promissory note in the amount of $4,571,550 that will convert into the balance of 15,238,500 shares on or prior to the close of business on July 1, 2002, provided Inprimis' shareholders approve the necessary increase of its authorized common stock.
Also, because GE-10 and GE-11 are located at the same orbital position as C-3 and C-4, the transition to GE-10 and GE-11 will be virtually seamless for our distributors.
In addition to starting production from the C-4 and C-4-2 wells, the possibility of beginning earlier production on the C-D Field using temporary facilities, before all permanent production facilities have been completed, is being reviewed.
The C-4 well was drilled on a previously untested structure, and discovered higher quality crude oil at depths greater than previously encountered on the block.
CHFA also anticipates issuing 1997 C-4 bonds on May 6, 1998.
In conjunction with the refunding, about half of the loans backing the 1986 bonds will be transferred to the 1997 C-4 bonds.
