Cancer
Brief On Cancer Management.
(the great killer disease)
cancer is a non-communicable disease which originates from all human cells that are capable of dividing. The only parts of the human body that can not form cancer are the hair, teeth and nails. According to the oxford medical dictionary, cancer is-“any malignant tumour, including carcinoma and sarcoma. It arises from the abnormal and uncontrolled division of cells that then invade and destroy the surrounding tissues. Spread of cancer cells (metastasis) may occur via the blood stream or the lymphatic channels or across body cavities such as the pleural and peritoneal spaces, thus setting up secondary tumours (metastases) at sites distant from the original tumours. Each individual primary tumour has its own pattern of local behaviour and spread; for example, bone metastasis is very common in breast and prostate cancer but less common in other tumours”…. Cancer is a major cause of death and the chances of formation increase as one get older.
More people die from cancer than the scourge of human immune-deficiency virus/ Acquired immune Deficiency Syndrone (HIV/AIDS), malaria and pulmonary tuberculosis combined, says an expert. There are various forms of growth in the human body the benign from that does not have the ability to spread to distant organs and is not referred to as cancer. Typical example is the fibroid or “uterine fibroma”. Another is the keliod that expands in fibrous scars on some people. However, growths that have acquired the property of spreading, whether by means of blood vessels or lymphatic channels to other organs like the lungs, brain or bones are called malignant cancers. “there are probably many causative factors, some of which are known; for example, cigarette smoking is associated with lung cancer, radiation with some sarcomas and leukaemia, and several viruses are implicated. A genetic element is implicated in the development of many cancers.
In more than half of all cancers a gene called p53 is deleted or impaired: its normal function is to prevent the uncontrolled division of cells”.-Oxford Medical Dictionary. The p54 is a gene which in the event of mutilation, would form a gene called oncogene which is capable of both initiation and continuation of malignant transformation of normal cells. It probably produce proteins which are growth factors regulating cell division that, under certain conditions become uncontrolled and may transform a normal cell to a malignant cell. Recent trials of gene therapy that involved replacing the oncogene with the normal version of the gene have had a limited success.
Treatment of cancer depends on the type tumour, the location of the primary tumour, and the extent of spread. Some experts say “early detection “ is the only cure to cancer. Some others say early detection saves lives, but it is not the only cure. Here I must define cure as a state of inability of the abnormal cells to grow and spread. They remain in the body in a state of suspended animation until death. There are of course occasions when absolute cure is achieved surgeon to excise it (remove, cut or expunge) and a dependable pathologist to look at the structure. Here it will be possible to define the stage, type or degree of rapidity of the cellular division so that the grade of malignancy can be determined. If the cancer is the early stages, and it is hoped that almost all of it has been exercised, adequate radio therapy to the area where the tumour is, can further assure the patient of a good result. “the rapid development of specialized drugs which are toxic to cells provides today useful adjuvant chemotherapy. They must however be carefully selected, matched and used for the advantage of the patient as inappropriate dosages can end up being toxic to ‘good cells’ of the blood and gastro-intestinal tract. The logistics for usage of these drugs is a separate specialization and such drugs simply cannot be bought and utilized off the counter”- Dominic Rodman, oncologist/radiologist.
It is therefore a relief to note that early detection with surgery, radiotherapy and chemotherapy will in many instances cure cancer. Today it is common to have cancer survivors. This not only includes such patients as described earlier, but also the family and medical personnel dedicated largely to the management and proximity of cancer. Cancer management therefore is a multidisciplinary approach involving surgeons, physicians, medical and radiological oncologists, pathologists, nursing care as well as palliative doctors. Management of cancer from the earliest time of discovery must be regarded as a palliative procedure even if cure is envisaged. Continuous counseling and maintenance of life style including adequate dieting will sustain the patient almost definitely. Adhering to this piece of advice will definitely reduce the death rate in a cancer prone society.
