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.

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).

    Cancer is a disease when abnormal cells divide without control and invade other tissues in the body. Normal cells divide in a regulated way to generate new cells that are needed to keep the body healthy. Cancer cells are when the normal cell division process goes awry. When this happens cells don’t die like they’re supposed to, and new cells are produced when the body doesn’t need them. When cancer cells form a lump of tissue it’s called a tumor. There are two types of tumors, malignant, and benign. A benign tumor isn’t cancerous, and can often be removed, and in most cases, they don’t come back. Benign tumors do not spread to other parts of the body like malignant tumors. Malignant tumors are cancerous. The cells within the malignant tumor spread from one part of the body to another and also invade nearby tissue which is called metastasis.

    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).

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.

    Most cancer happens at different rates in other parts of the world. Lifestyle can increase a person’s risk for cancer because it can affect cells that are prepared to become cancerous by helping them grow. The environment can change genes which cause them to be cancerous in the first place. An abnormal cell is what causes a tumor. This cell appears to be no different from normal ones and only functions and divides when needed. Then, even though the organ it supports has a sufficient amount of cells, it divides uncontrollably (Weinberg 1-2).
