Ex. 25. Read and translate the following text:
Tumors are masses or growths, which arise from surrounding normal tissue. They may be either malignant (progressive and life-threatening) or benign (non-progressive and not life-threatening). Benign tumors display slow growth and are encapsulated. So that tumor cells cannot invade the surrounding tissue. Malignant tumor growth is invasive. It extends beyond the tissue of origin into adjacent organs. The major groups of malignant tumors are carcinomas, sarcomas, and mixed-tissue tumors.
A carcinoma is a malignant tumor derived from epithelial tissue (glandular, skin, linings of internal organs). A sarcoma is a malignant tumor derived from connective tissue (blood, bone, muscle, fat, or cartilage). Mixed-tissue tumors are derived from tissue, which is capable of differentiating into epithelial as well as connective tissue.
Malignant neoplasms lack the normal growth control that is exhibited by most other adult tissues, and in many ways they resemble embryonic tissue. Rapid growth is one characteristic of embryonic tissue, but as the tissue begins to reach its adult size and function, it slows or stops growing completely. This cessation of growth is controlled at the individual cell level, cancer results when a cell or group of cells for some reasons breaks away from that control. This breaking loose involves the genetic machinery and can be induced by viruses, environmental toxins, and other causes. The illness associated with cancer usually occurs as the tumor invades and destroys the healthy surrounding tissue, eliminating its function. Malignant tumor can spread by local growth and expansion or by metastasis, which results from tumor cell’s separating from the main mass and being carried by the lymphatic or circulatory system to a new site where a second tumor is created.

Ex. 28. Read the following text, entitle it, and write new terms out. Retell the text:
Surgery has long been the foundation of cancer treatment. The goals of surgery can vary. It can be done to remove a cancerous growth from the body, or to learn if malignant cells have spread to other parts of the body. Surgery is most successful if the cancer has not spread.
Radiation therapy (X-ray therapy, radiotherapy, or irradiation) can be used to destroy cancer cells. Radiation therapy is either part of the treatment or the only treatment for about half of the patients. This form is effective only for the cancer cells within the area receiving the radiation. Radiation may be used before surgery to shrink a cancerous tumor, after surgery to stop growth of any remaining cancer cells, or alone or with anticancer drugs to destroy a malignant tumor. It is particularly effective when used to treat certain types of localized cancers such as malignant tumors of the lymph nodes or vocal cords. But radiology may produce troublesome side effects. They are swallowing difficulties, dry mouth, nausea, diarrhea, hair loss, and loss of energy.
Chemotherapy is the use of medications to treat cancer. For some types of malignancy chemotherapy may produce a cure, in other cases (when the cancer is not curable), it can relieve symptoms and enhance the quality of life for a patient. Cancer chemotherapy does not always mean the use of only a single drug. Combination chemotherapy consists of giving a group of drugs that work together to kill cancer cells. Anticancer drugs can affect normal tissue cells as well. Depending on the specific drugs used, chemotherapy can produce various side effects similar to those of radiation therapy. These toxic reactions include hair loss, sores in the mouth, difficulty swallowing, nausea, vomiting, diarrhea, bleeding, and infection. In general, these effects of chemotherapy and radiation are reversible.
Immunotherapy might involve the use of biological agents, known as lymphokines, that normally are produced by immunologically oriented cells. The best documented immunotherapeutic agents are interferon and interleukin-2.
Ex. 29. Having read the following text, compose short dialogues on it:
NEW METHODS TO FIGHT CANCER
Cancer treatment is constantly evolving. Some of these methods are now accepted therapy, and others are under investigation and are experimental. Physicians often combine these approaches with chemotherapy and radiation.
T Cells. T cells recognize and attack cancer cells. Researchers hope to remove T cells from the body, stimulate growth, and return them in large numbers to fight cancer. Someday, vaccines may be available to promote growth of T cells.
Gene therapy. Many tumors grow because normal genes go awry, changing healthy cells into cancerous cells. Genes that help fight cancer can also fail to work properly. With gene therapy, physicians hope to replace defective genes and encourage the growth of healthy genes.
Laser. High-intensity light shows potential for treatment cancers of skin, trachea, lungs, esophagus, stomach, colon, rectum, and anus.
Hyperthermia. Since the early 1800s, physicians have known that heat can harm some tumors. Researchers now are evaluating hyperthermia to treat cancer of the breast, lymph nodes, skin, eyes, and cervix.
Cancer is characterized by abnormal growth of cells, which form tumors. It can develop in various tissues and organs of the human body. Cancer cells divide without restraint. They crowd normal cells out and affect their normal function and growth. Cancer cells can spread via the blood or lymph system to other parts of the body. Tumors are masses or growths, which arise from surrounding normal tissue. They may be either malignant or benign. Cells of benign tumors do not invade or destroy surrounding tissues. But the mechanism of cancer developing is not fully known. It is very dangerous disease. An early diagnosis identifies the type and location of the cancer. Cancer can be treated before it spreads to other organs or tissues. Cancer therapy confines and kills the malignant cells. This therapy includes using X-rays, surgical treatment, and chemotherapy.

Ex. 9. Read the following words and word-combinations:

Ex. 10. Read the following text:
Most gastric tumors are malignant. They affect twice as many women as men, usually between the ages of 50 and 70. Approximately 1 of 10 stomach tumors is benign. Like the malignant tumors, the most common early symptom of a benign tumor may be microscopic bleeding that can be detected only by laboratory examination of the stool.
The cause of malignant gastric tumor is unknown. Genetic factors may have some influence. They are 2 to 4 times more common in members of the immediate family of people with the disease.
There is no one symptom that will suggest that the person has a malignant gastric tumor. One of every four persons with a malignant tumor has the same symptoms as someone with a peptic ulcer. They are discomfort in the upper or middle region of the abdomen, black stools, and vomiting after meals. But other symptoms are more serious: vomiting of blood, weight loss, anemia, and bloated feeling after meals.
Malignant tumor is difficult to treat. If the cancer is confined to the stomach, the chance of cure is good. However, the disease often has spread, and the chance of cure is then significantly decreased.
If the tumor is malignant, surgical removal offers the only chance to cure. The likelihood of success depends almost exclusively on whether the cancer has spread (metastasized) to other areas of the body. If the cancer is caught early and it is determined that surgery can remove all of the affected areas, full recovery is possible. Sometimes surgery may be recommended to alleviate pain, bleeding, or obstruction.
In addition to surgery for malignant tumors, the physician may choose chemotherapy as an additional treatment, using a number of anticancer medications. Radiation is sometimes used, but both radiation and chemotherapy can only relieve the symptoms, they do not cure the cancer. If the cancer is too far advanced for chemotherapy or surgery to be effective, analgesic drugs may be used to reduce pain.
