What is cancer?

Cancer is a malignant growth or tumour that is prompted by an unrestrained division of unusual cells in the body. These cells have no function. Two main kinds of tumours: Malignant tumours that tend to disseminate to other parts of the body after a period of time whilst benign tumours that usually stay on their formation site. Malignant tumours are dangerous because they can block blood vessels, disrupt the functioning of hollow organs and even cause bleeding.

An explanation of what happens in the cell as cancer is formed.

Chromosomes in the nucleus send mixed up messages about how it is to divide to the rest of the cell. This causes the cells …show more content…

What are the causes of cancer?

There is no single cause for cancer. There are many different causes that have been linked with cancer. Such as cigarette smoke, excessive exposure to radiation, exposure to asbestos fibres, obesity, a lack of exercise, and carcinogens- which are cancer causing chemicals. An example of a carcinogen would be certain red food colourants.

Cancer can even be caused by genetic mutations that can be inherited. This is why people that have a family history of cancer must be careful of exposing themselves to cancer causing substances, as they are more likely to develop cancer.

There is no evidence that viruses have been linked to causing cancer. However, some viruses have been proven to be involved in the development of certain tumours. Chronic irritation is also a possible cause for skin cancer.

There has been a study that has shown that there is a link between anxious, over conscientious, introverted people and them developing cancer later in

    Cancer is the term used to describe a group of diseases consisting of hundreds of ailments and although there exists so many different types of cancer, they all begin in a similar way. The body is made up of over a trillion cells, and cancer is the uncontrolled growth of malfunctioning cells in the body (Dawson, 1996). “Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries” (American Cancer Society, 2012).

    The cancer cells from gene-mutation. Scientists now know some of the risk factors for lung cancer can cause certain changes in the DNA of lung cells. These changes can lead to not normal cell growth and, sometimes, cancer. DNA is the chemical in each of our cells that makes up our genes and how our cells function. People usually look like their parents because they are the source of our DNA. But DNA affects more than how we look; it also can affect our risk for developing certain diseases, including some kinds of cancer like lung cancer etc…Some people inherit DNA mutation from their parents that greatly increase their risk for developing certain cancers.

If the spot or mole comes back positive for skin cancer, they next will run more tests to see if it has spread throughout the body. The first thing the doctor will ask you is the time frame from when you first started noticing this on your body,

    In the United States 85 to 90 percent of all lung cancer cases are related to smoking. Cigarette smoking is the main cause of lung cancer (Scientific American, “Lung Cancer';). Second-hand smoke, inhaled by non-smokers, increases a person’s chance of acquiring lung cancer (Beau Halton). Men who smoke increase their chance of dying from lung cancer about 23 times and women increase their chances 13 times (“Lung Cancer Awareness Campaign,'; 3/23/99). However, lung cancer may also be caused by long term exposure to radon, a naturally present radioactive gas (SIRS, “What is Cancer?';). The residue of burned petroleum and coal can contribute to lung cancer (Scientific American, “Lung Cancer';). The development of lung cancer seems to be also affected by genes. The gene histidine triad blocks the formation of tumors, so a defective gene could make one more likely to form a tumor (Microsoft, “Lung Cancer';).

    When you think of lung cancer, you think of smoking, it is the most common cause of cancer but there are many other causes that people don’t think about. You don’t have to be a smoker to develop lung cancer, secondhand smoke, radon, diesel exhaust, air pollution, and some gene changes cause lung cancer as well. The genes that help a cell grow, divide, or stay alive are called oncogenes. The genes that slow down cell division, or cause calls to die when they are supposed to, are called tumor suppressor genes. Cancer can be caused when these oncogenes turn on, or even when these tumor suppressor genes decide to turn off. Most of the genes that cause lung cancer are developed through your life; inherited genes rarely play a huge factor in lung cancer.

    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, radon gas, tobacco, PVC and much more from our chemical industries. The environment especially near to the industrial that produce chemical waste can be one of the causes lead to cancer. Cancer also have relation with our age, lifestyle, and diet and also can be genetically inherited. It is believed that older people have higher tendency to get cancer than younger people. Our lifestyle and diet also plays a role causing a cancer by our daily life routine. Smoking tobacco and eating unconsciously (still in research) can also increase the possibility to get cancer especially lung cancer that cause by smoking tobacco. There are several cases, cancer were inherited from their parents. Various type of viruses such as HIV, HPV, EBV and many more virus has a high capabilities to increase the chance a patient to get a cancer because these viruses lower their body immunity to disease.

  • The Biology of Breast Cancer

    Breast Cancer, as well as other forms of cancer, scientists do know how it occurs, but they do not know an exact cause. There are some genes in our body called oncogenes, genes that have potential to cause cancer, that increases the speed of cell division while other genes such as tumor suppressors, cause the cells to die at the correct time. Mutations that occur in the DNA, which “turn on” the oncogenes or “turn off” tumor suppressor genes, will cause some of the cells to be cancerous in the breast("American Cancer Society"). Also, Breast Cancer can be increased by inherited gene mutations and acquired gene mutations. The risk of Breast Cancer can be increased dramatically, through the inheritance from parent to offspring, if a mutation occurs. For example, if a suppressor gene, such as BRCA, forms a mutation, then it is likely to be passed to future generations. This gene no longer suppresses abnormal growth, therefore there is a higher chance of cancer being developed. Even though Breast Cancer can be inherited it is more likely to be acquired through one breast cell. The acquired mutations could be a result of of radiation or cancer-causing chemicals. ...

    All cancer has a genetic basis. It is triggered by mutations in the genes of a cell which then cause the cell to abnormally reproduce. Many of these gene changes are caused by random mutations when the cell is dividing. It only takes one cell mutating to cause cancer. There are no symptoms for the beginning of cancer and only five to ten percent of all cancers are caused by parents passing down genetic mutations to their children. The remaining are caused by environmental changes (Douglas).
