What is disease???
The term 'disease' refers to any abnormal condition of an organism that impairs function. This causes discomfort, dysfunction, distress, or death to the person afflicted or those in contact with the person.
We decided to concentrate on two diseases: AIDS and CANCER, because they are one of the most frequent. We think that it is really important to people know more about them.
AIDS means Acquired Immune Deficiency Syndrome. It is a sickness that attacks the body’s natural defence system against disease. AIDS itself does not kill, but because the body’s defence system is damaged, the patient has a reduced ability to fight off many other diseases including flu or the common cold. We know that AIDS is caused by a virus HIV which invades healthy cells, including the white blood cells that are part of our defence system. The virus takes control of the healthy cell’s genetic material and forces the cells to make a copy of the virus. The cell then dies and the multipled virus moves on to invade and kill other healthy cells
a person sick for aids
People ill with AIDS are victims of the HIV, but also of the society, which often is not tolerant enough to accept them. They live under big pressure, afraid of dying lonely and of painful death. They lose their jobs, friends and family. People are really afraid of AIDS mostly because they don’t know enough about it. They believe , that they can very easily get infected, but it’s not
true.
The truth is that it’s not possible to get infected by touch, kiss or using the same bath. However, accidental sexual contacts or unsterilized medical equipment can be responsible for the contagion. It also can be passed in blood products or from a pregnant woman with AIDS to her baby .
If we don’t want to be infected, we must use condoms and sterilized medical equipment.What is very important for people is to educate themselves about the risk of AIDS , otherwise we may never be able to combat the epidemic.
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to spread, either by direct growth into adjacent tissue through invasion, or by implantation into distant sites by metastasis (where cancer cells are transported through the bloodstream or lymphatic system). Cancer may affect people at all ages, but risk tends to increase with age. It is one of the principal causes of death in developed countries.
There are many types of cancer. Severity of symptoms depends on the site and character of the malignancy and whether there is metastasis. A definitive diagnosis usually requires the histologic examination of tissue by a pathologist. This tissue is obtained by biopsy or surgery. Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. As research develops, treatments are becoming more specific for the type of cancer pathology. Drugs that target specific cancers already exist for several types of cancer. If untreated, cancers may eventually cause illness and death, though this is not always the case.
The most frequent types of tumour
Many forms of cancer are associated with exposure to environmental factors such as tobacco smoke, radiation, alcohol, and certain viruses. Some risk factors can be avoided or reduced.
