• What is Cancer?

Cancer is a common name for a group of diseases characterised by uncontrolled proliferation of abnormal cells. Cell division is the mainstay of human life. Human body is made up of several organs like brain, lung, liver, stomach etc. and each organ is made up of cells. Organs and tissues are constituted by cells characteristic of that organ. Cells divide for growth of an organ, for repairing tissue damage and to maintain functions of the organ. The divided cells are the exact replica of the parent cell. Sometimes due to some faulty mechanism or due to factors which are unknown yet, the divided cells are abnormal i.e., their structure is not the same as that of its parent cells. They cannot discharge the functions like the normal cells but requires the same food as the normal cells. These cells start dividing and a large number of abnormal cells are produced. As a result of the proliferation of abnormal cells the body organs do not function normally and the persons nutrition is impaired rapidly. These cells cluster to form lumps, swellings, and sometimes produce ulcers in the respective organs. However in the case of blood cancer — Leukaemia - the abnormal cells start circulating throughout the blood streams so, no visible lump or swellings are observed. (Cancer is known by its different types like sarcoma, lymphoma, leukaemia, myeloma, carcinoma etc.). The most important characterisitc of cancer is that the cancer cells breakaway from the tissue or organ of origin and starts spreading to other parts of the body through lymphatic channels or cavities or blood vessels. They then deposit themselves in other parts of the body where it grows again. This is known as the metastasis. Because of this unique characterisitc it becomes difficult to cure or to control cancer when it has spread.

• What is cancer of the vulva?

Cancer of the vulva is the presence of cancerous cells on the skin of the vulva. It is diagnosed by tissue biopsy. Treatment consists of removal of the growth of abnormal cells. This surgery can vary from day surgery to extensive surgery requiring hospitalization. The treatment will depend on the biopsy result and the physical examination by the Gynecologist Oncologist.

• What is cancer of the prostate?

The prostate is a walnut-sized gland that is part of the male reproductive system. It is located deep in the pelvis between the bladder and the penis. The prostate gland produces fluid that is part of semen. The prostate is the most common site for new cancers in men.

Cancer prostate, like other cancers, is an abnormality of the bodys cells. All cells reproduce themselves by dividing. Normal growth and repair of tissue takes place in an orderly manner. Cancer is a kind of abnormal growth of cells that may invade and destroy nearby tissues and organs or spread to other parts of the body.

• What Is Breast Cancer?

Breast cancer is the most common form of cancer among women in Northern Ireland. While the incidence of breast cancer is infrequent in women under 40 years of age, the risk increases with age - 1 in 12 women will develop breast cancer before the age of 75. However, encouragingly, more women than ever are surviving breast cancer with early detection being a key to survival.

Cancer is not a single disease; there are many different types depending on what type of cell in the body has caused the cancer. In a healthy body the cells (skin cells, liver cells, blood cells etc) divide and multiply in a controlled way. Sometimes cells divide in an uncontrolled way and become abnormal which creates a mass of irregular cells. This mass of cells is called a tumour. Tumours can be harmless (benign) or cancerous (malignant). Cancerous or malignant cells have the ability to invade and damage other tissues by forming new colonies of abnormal cells called secondary growths or metastases.

Cancer of the breast is defined according to the part of the breast where the tumour begins. The breast is made up of sections called lobes and lobules which are connected by ducts. Cancer can be ductular ie arising from the ducts, or lobular ie arising from the lobes or lobules. If a cancer spreads to other parts of the body it is called metastatic. Breast cancer can spread to the lymph nodes, lungs, liver, bone, skin and brain.

• What is lung cancer?

Cancer is a disease in which certain body cells don’t function right, divide very fast, and produce too much tissue that forms a tumor. The lungs, a pair of sponge-like, cone-shaped organs, are part of the body’s respiratory system. When we breathe in, the lungs take in oxygen, which our cells need to live and carry out their normal functions. When we breathe out, the lungs get rid of carbon dioxide, which is a waste product of the body’s cells. …

Lung cancer is the most frequently occurring cancer in the US, accounting for 30% of all diagnosed cancer. The largest number of asbestos related deaths occurs from lung cancer. Most lung cancer cause by asbestos inhalation starts in the lining of the bronchi, the tubes that lead from the windpipe into each lung. Lung cancer caused by asbestos exposure can also begin in the windpipe itself, the bronchioles, smaller tubes which branch off from the bronchi, or in the alveoli. …

Cancer is a group of diseases caused by rapidly dividing cells. As these cell divide they change and can no longer do the job they were intended. Lung cancer is a disease that begins in the cells of the lungs. It is currently believed that lung cancer may slowly develop over ten or more years before it seen on x-ray or some other radiological scan. However, lung cancer can spread quickly to other parts of the body, because it starts out in an organ through which the blood in the body flows through. …
