Ultrasound: High-frequency impossible to hear muffled sound waves are sent and these waves are bounced off by body tissues. The movement of sound waves are recorded to give the information about the structure of the inside organs. The good transmission of waves is ensured by placing an instrument near the skin and by smother the skin surface by an oily substance. Oil substance probably a mineral oil is put for the diffusion of sound waves properly. The ultrasound instrument produces dumpy sound waves in cyclic beats. Each wave is in different speed of motion and invades through the tissues inside the body and becomes aware of boundaries amid tissues of diverse compactness. These waves are passed back to the ultrasound monitor and recorded. This record is called echogram or sonogram . This instrument is used not only by radiologists, but also by ophthalmologists to detect intracranial and ophthalmic lesions. Cardiologists also use this instrument to identify blood v

In order to take the best possible view of the part of the body being radiographed, the patient, film, and x-ray tube must be positioned in the most favorable alignment possible. There are special terms used by radiologists to designate the position for direction of the x-ray beam, the patient's position, and the motion and position of the part of the body to be examined. Some of the important x-rays terms are as follows: AP view or anteroposterior view: In this view the patient is usually supine i.e. lying on the back and the x-ray tube is aimed from above at the frontal side of the body and the beam is passed from the anterior to posterior. The film lies underneath the patient. The AP view may also be taken with the patient in the upright position. PA view or posteroanterior view: In this view, the patient is upright with back to the x-ray machine and the film to the chest. The x-ray machine is aimed horizontally at a distance of about 6-feet from the

1. Adjuvant therapy: Assisting primary treatment. Drugs are given early in the course of treatment along with surgery or radiation to attack cancer cells that may be too small to be detected by diagnostic techniques. 2. Alkylating agents: Synthetic chemicals containing alkyl groups that interfere with DNA synthesis. 3. Anaplasia: Loss of differentiation of cells. Reversion to a more primitive cell type. 4. Antibiotics: Chemical substances produced by bacteria that inhibit the growth of cells used in cancer chemotherapy. 5. Antimetabolites: Chemicals that prevent cell division by inhibiting the formation of substances necessary to make DNA and used in cancer chemotherapy. 6. Apoptesis: Programmed cell death. Apo- means off, away, and -ptosis means to fall. Normal cells undergo apoptesis when they are damaged or aging. Some cancer cells have lost the ability to undergo apoptesis and live forever. 7. Benign: Noncancerous. 6. Biolo

BIOLOGICAL THERAPY TO CURE CANCER:  An additional fresh line of attack to cancer management is the employment of the body's individual resistance systems to scrap tumor cells. Researchers see the sights how the ingredients of the immune system can be brought back, developed, imitated, and influenced to annihilate cancer cells within the body. Chemical materials brought into being by standard cells that moreover in a straight line wedge tumor development before kindle the immune system and additional body barricades are called genetic reaction modifiers. The instances of these materials are interferon prepared by lymphocytes, monoclonal antibodies created by mouse cells, and proficiency of strapping to human tumors, colony-stimulating factors or CSFs so as to accelerate blood-forming cells and turn around the upshots of chemotherapy, and interleukins with the intentions of stimulating the immune system to annihilate tumors. Now we will sort out chemotherapeutic and biolog

CHEMOTHERAPEUTIC AGENTS:  The subsequent list categorizes all cancer chemotherapeutic agents: 1. Plant byproducts: These chemical substances are drawn from plants. These chemical materials are used recurrently in mixture as a supplement to other chemotherapeutic agents. The offshoot effects take account of myelosuppression, alopecia, and smash up of nerves. 2. Antimetabolites: These drugs slow down the amalgamation of drugs so as to the essential part of DNA or possibly will unswervingly hunk the copying DNA. The offshoot consequences of antimetabolites are myelosuppression with leukopenia, thrombocytopenia, and bleeding. The other side effects are toxicity to the oral and digestive tract, as well as stomatitis called sore mouth, nausea, and vomiting. 3. Alkylating agents: These are artificial amalgams be full of two or more element groups names alkyl groups. The chemical substances get in the way by means of the development of DNA fusion next to putting
