Cancer is a class of diseases characterised by out-of-control cell growth. There are over 100 different types of cancer and each is classified by the type of cell that is initially affected. Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumour
(expect in the case of leukaemia where cancer prohibits normal blood function by abnormal cell division in the blood stream). Tumours can grow and interfere with the digestive, nervous and circulatory systems and they can release hormones that alter body function. (knnumakara,2008).
There are five broad groups that are used to classify cancer.
Carcinomas: cancer that begins in the skin or in tissue that line or covers internal organs.
Sarcoma: cancers that begin in the bone, cartilage, fat muscles, blood vessels or other connective or supportive tissues.
Leukaemia: cancer that starts in the blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.
Lymphoma and Myeloma: cancers that begin in the cells of the immune system.
Central nervous system cancers: cancers that begin in the tissues of the brain and spinal cord.
Common environmental factors leading to cancer include: tobacco, diets and obesity infections, radiation, lack of physical activity and environmental pollutants (Anand, 2008). There are different types of cancer but this project is based on liver cancer.
The liver is the second largest organ in the body and is located below the right lung; it is divided into the right and left lobes. Nutrient-rich blood is carried by the portal vein from the intestine to the liver while oxygen-rich blood reaches the liver from the hepatic artery. The liver performs important roles in the body.
Liver cancer is malignant tumours that grow on the surface or inside of the liver. Cancer that starts in the liver is primarily liver cancer and cancer that spread to the liver from another organ in metastatic. (Forman, 2011 ). The presence of cancer can be suspected on the microscopic examination of a biopsy specimen. Most cancer can be treated, possible treatment include chemotherapy, radiotherapy and surgery. (Forman, 2011)
The aim of this study is to estimate the level of electrolyte, urea and creatinine in a patient suffering from the cancer of the liver and that of a normal person.
