Cancer has been seen in humans as one the most potentially fatal disease for thousands of years and only in the recent couple of hundred years have we discovered that most information necessary to bring us to today’s understanding and knowledge (Kenny 2007, Weinberg 1996) was achieved by extensive research of cells, DNA, and epidemiology studies. As we know, currently cancer is acknowledged as having over a hundred different diseases, and is known to be the result of mutations of the genes and almost
CONCLUSION Cancer has become the one of the most feared things for human beings. The various type of cancer have been discovered and there are still a lot of it that undiscoverable. Cancer is a complex disease that have a group of disease. The cancer itself cannot be describe by words. The causes of this cancer is still not being able to be discovered fully. There are only minor factor that can lead to this disease. The carcinogens are believed to be one of the causes that lead to cancer such as asbestos
Cancer is a deadly disease that affects millions of American families each year. In cancer, cell division isn't controlled. Usually, cells have to go through a set of checks and balances before they divide, in cancer that is nonexistent. The cells just keep duplicating until they eventually form disorganized clumps called tumors. Tumors can either be, benign, meaning that they do not possess the power to metastasize to surrounding areas. If a tumor has the power to metastasize, it is classified as
These cells (that have cancer in them) are able to go into other muscles or part of body by growing into them. They can also get into other tissue by putting themselves into faraway places in the body by “Metastasis”. Metastasis is a process that when cancer cells move through the blood stream or lymphatic system. When this happens, a person’s cancer can be spread inside his/her body. Cancer can affect anybody at any age. Most types of cancer are more possible to affect people as they get older.
Cancer Overview Cancer is one of the primary causes of death worldwide, and one of the two largest groupings of diseases in the Western world, with the other being cardiovascular diseases (Teunissen, et al., 2007). Globally, one out of every eight deaths is cancer related, but what does this truly mean? Cancer is a term used to describe the diseases that involve the uncontrolled division of cells, also known as neoplasms, which typically originate from a larger mass of cells, referred to as a tumor;
Cancer can develop anywhere in the body. Cells grow abnormally and become cancerous because of environmental factors, such as smoking cigarettes and exposure to radiation; genetics, poor diet, lack of physical activity, and even just luck (Stern et al., 2004). Even though genetics play the primary role in the development of cancer, the environment in which one lives also contributes to the chances of getting cancer. Some of the environmental factors that influence the development of cancer include
Cancer Cancer is a broad category of the disease characterized by undefined outgrowth of cells that divide uncontrollably to form nasty tumors within an individual. The cancerous cells causing the tumors grow and divide creating new blood vessels to feed themselves in a process called angiogenesis (Veeratterapillay, 2012). The tumors often spread to other parts of the body swiftly due to the unregulated growth and dividing of the cells through the bloodstream or the lymphatic systems in the body
and physiology of the human body. In case malignant growths develop due to abnormality in the body cells, a condition known as cancer develops. Cancer basically can occur on any part of the body. The most common forms of cancer are lung cancer, breast cancer, prostate cancer, cervical cancer, cancer of the brain and colon cancer among others. Development of colon cancer begins when the process of the normal replacement of cells on the colon lining is interfered with which in most cases is due to
Definition of cancer. Cancer is a wide range of diseases which form a subset of Neoplasm. A tumor is a group of Neoplasm that have undergone unregulated growth. Neoplasm serves no physiological function and will often form a lump. Cancer can result by genetic that are inherited from ancestors. It is possible to be born with a specific genetic mutations or a fault in a certain gene that makes the person more likely to develop cancer later in life. Cancer classification nowadays, types of primary
There are various different forms of cancer affecting all different parts of the body. Healthy cells will grow, divide and eventually die making way for new cells to take their place. In young healthy youth this process is faster in order to aid an individual in growing. In an adult individual cells divide and only replace themselves when they have worn out or are incapable of repairing injuries (Fox, 2009). Cancer is a process in which the cell starts to grow without control or a stop mechanism
