Although cancer affects every age group, most cancers occur in people old than 65 years of age. Overall, the incidence of cancer is higher in men than in women and higher in industrialized sectors due to exposure to chemical agents.
![Page 7: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/7.jpg)
The overall rate of mortality from all cancer has fallen by 11% in the last 10 years, though there are large variations in this trend between different cancers. The main reasons for the decrease in mortality are: Primary prevention of cancer for example a reduction in
smoking.
Earlier detection due to screening programmes.
e.g Mammogram
Better treatment, for example new drugs and new protocols.
![Page 8: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/8.jpg)
Certain categories of agents or factors implicated in carcinogenesis.
Carcinogen
Is any substance or agent that promotes cancer development. Generally cause genetic mutation, i.ethey damage DNA in cells, therefore interfering with normal biological processes
![Page 9: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/9.jpg)
INFECTION
Chemical Agents
Genetic and familial factors
Dietary factors
Hormonal agents
PHYSICAL AGENTS
![Page 10: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/10.jpg)
Virus and bacteria are though to incorporate themselves in the genetic structure of cells, thus altering future generations of cells. For example
The Epstein-barr virus
Hepatitis B virus
Human immunodeficiency virus (HIV)
Bacterium helicoactor pylori which is important factor in Ca. stomach
![Page 11: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/11.jpg)
Most hazardous chemicals produce their toxic effects by altering DNA structure in body sites distant from chemical exposure
The liver , lungs and kidneys are the organ systems most often affected, presumably because of their roles in detoxifying chemicals
Tobacco
Alcohol
Uranium
Benzene
![Page 12: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/12.jpg)
Almost every type has been shown to run in families. Genetic factors play a role in cancer cell development. Abnormal chromosomal patterns and cancer have been associated with extra chromosomes
![Page 13: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/13.jpg)
The risk for cancer increases with long-term ingestion of carcinogens or co-carcinogen or chronic absence of proactive substances in diet. Dietary substance associated with an increased cancer risk include
Fats
Alcohol
Smoked meat
Foods containing nitrates and nitrites
High caloric dietary intake
![Page 14: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/14.jpg)
In some Tumors, i.e (Breast and prostate) cancer growth may be promoted by disturbances in hormonal balance either by the body's own (endogenous) hormone production or by administration of exogenous hormones.
![Page 15: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/15.jpg)
Sun exposure
There is a fair evidence that reducing exposure to ultra-violet radiation reduces the incidence of non-melanoma skin cancer. Increasing exposures of ultra-violet over a lifetime increase the risk of basal cell squamous cell carcinoma.
Exposure to ionizing radiation can occur with repeated diagnostic x-ray procedures or with radiation therapy
![Page 16: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/16.jpg)

Knowing cancer biology has opened up the opportunity for targeted treatment and method of screening.
Cancer is not one disease but many; although there are some striking similarities in how all cancers develop. Cancer is a monoclonal disease, formation of a normal cell into its malignant counterpart is an accumulative, multistage process of gene mutation. As each mutation occurs, the cell's DNA becomes less stable. The genes involved control the process of cell division (cell cycle).
It may take many years for multiple mutations of a single cell to occur. This explains the increasing risk of cancer as we get older.

There are hundreds of different cancers, due to the many tissue types and point of origin for cancer within the human body. They can be loosely classified into main types;
CARCINOMAS
SARCOMAS
MYELOMA
LEUKAEMIAS
LYMPHOMAS
![Page 21: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/21.jpg)
CARCINOMAS:
Are cancers of epithelial tissue. Divided into two subtypes:
- ADENOCARCINOMA:
which develops in an organ or gland
- SQUAMOUS CELL CARCINOMA
which develops in the squamous.
- SARCOMAS:
Originate in supportive and connective tissues such as bones, tendons, cartilage, muscles and fat.
MYELOMA:
Originates in the plasma cells of bone marrow.
![Page 22: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/22.jpg)
LEUKEMIAS:
(blood cancers) are cancers of bone marrow. They are further divided into myeloid and lymphoid types based on the specific blood cell line from which they originate.
- ACUTE LYMPHOPLASTIC LEUKEMIA (ALL).
- CHRONIC LYMPHOPLASTIC LEUKEMIA (CLL).
- ACUTE MYELOID LEUKEMIA (AML).
- CHRONIC MYELOID LEUKEMIA (CML).
LYMPHOMAS:
Cancers of the glands or nodes of the lymphatic system. They may also occur in specific organs such as the stomach, breast or brain. Divided into:
.Hodgkin's diease-
Non-hodgkin's lymphomas.-
![Page 23: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/23.jpg)
Treatment options offered to cancer patients should be based on realistic and achievable goals for each specific type of cancer. The range of possible treatment goals may include:
Cure ------ Complete eradication of malignant disease.
Control ------ prolonged survival and containment of cancer cell growth.
Palliative ------ relief of symptoms associated with the disease.
![Page 24: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/24.jpg)
Multiple modalities are commonly used in cancer treatment. A variety of therapies, including:
Surgery.
Radiation therapy.
Chemotherapy.
And biologic response modifier (BRM) therapy.
![Page 25: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/25.jpg)
Antineoplastic agents are used in an attempt to destroy tumor cells by interfering with cellular functions and reproduction.
Chemotherapy may combined with surgery or radiation therapy, or both to reduce tumor size preoperatively,to destroy any remaining tumor cells postoperatively, or to treat some forms of leukemia.
![Page 26: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/26.jpg)
Prevent cancer cells from multiplying, invading, metastasizing.
![Page 27: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/27.jpg)
Cytotoxic drugs are classified according to their mechanism of action.
![Page 28: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/28.jpg)
Most chemotherapeutic drugs target DNA within the cell in some manner, this action may result in direct interference with DNA, inhibition of enzymes related to RNA or DNA, synthesis or both and /or destruction of the cells’ necessary proteins.
![Page 29: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/29.jpg)
Chemotherapeutic agents may be administered in the hospital, clinic, or home setting.
![Page 30: Mangement of cancer in nursing](https://reader033.vdocuments.mx/reader033/viewer/2022042602/55a72ff31a28abbc668b4664/html5/thumbnails/30.jpg)
Safety recommendation for prepartion and handling of anti-neoplastic agents are as follows:
- Proper aseptic techniques must be used in the prepation of chemotherap to protect the patient health care professioinal.
- Use a biologic safety cabinet (laminar air-flow cabinet) for the preparation of all chemotherapy agents.
- Wear surgical gloves when handling anti-neoplasticagents.
- Wear disposable, long-sleeved gowns when preparing and administering chemotherapy agents.
- Dispose of all chemotherapy wastes as hazardous materials.
