Facts About Cancer Cells

A cancer cell is cell growth as well as abnormal development. Cancer cells have the ability to reproduce and multiply as many. Then a group of cancerous cells grows into a new network called tumors. The tumor continues to grow along with the development and growth of cancer cells, when the tumor is constantly growing relentlessly then it can be said to be a malignant tumor.

Cancer cells have many differences with normal cells in the body. Not only are growing aggressively, but cancer cells can also spread to other body parts and build a new network. Cancer cells also cannot be dead and damaged by itself like other normal cells. Here are the facts about cancer cells that may not have been you know.

1. There are more than 100 types of cancer in the world

Cancer cells can grow in various parts of the body, while the body has many different kinds of cells. Cancer cells can grow on organ, tissue, or cells. the most frequent Types exist on the incidence of cancer is a type of carcinoma. Carcinoma is a cancer cell that grows on the body epithelial tissue, that tissue lining various organs, blood vessels, and networks that exist in the body.

Whereas another cancer cell type is a sarcoma. Sarcoma is a cancer cell that normally grows on bone tissue, muscle, adipose tissue, glands, tendons, and joints. Leukemia is a type of cancer that grows in the bone marrow that results from the white blood cells that grow abnormally. While lymphoma is cancer that is caused by the growth of B cells and T cells are abnormal in the body.

2. Cancer cells could be derived from a virus

Cancer cells grow and develop because of several factors that support such as radiation, exposure to chemicals, ultraviolet light and the process of DNA replication that failed. But it turns out that in addition, cancer cells can also arise due to the virus.

The virus has the ability to cause cancer and is triggered by genetic factors. Known as much as 15% to 20% of the total cancer cases occur caused by the virus. Viruses change DNA on normal cells, so the cells mutate and grow aggressively. Epstein-Barr virus resulting in illness Burkitt's lymphoma, virus hepatitis B causes liver cancer, and human papillomavirus (HPV) can cause uterine cancer.

3. One-third of cancers can be prevented

According to WHO, as much as a 30% incidence of cancer can actually be prevented. Cancer caused by factors or genes the offspring reaching only 5% to 10% of the total cancer cases. Moreover, cancer occurs due to various environmental factors, such as infections, pollution, and lifestyle. Prevention can be done to prevent cancer is to prohibit the use of tobacco and smoking. Cigarette smoking is the main reason the causes of cancer, 70% of cases of lung cancer caused by smoking habit.

4. Cancer requires high sugar

The more sugar that is ' eaten ' by cancer cells, the faster they grow. Sugar is a substance that is required by the normal cells to perform respiration and then generate the energy used to do physical activity.  Cancer cells require high sugar levels to reproduce itself.

5. Hiding in the body

Cancer cells can hide from the immune system by way of growing on normal cells. For example, some tumors that grow in the lymphatic glands to secrete proteins, the protein is also supposed to be excreted or secreted by the lymphatic glands. Therefore, the immune system is not able to detect where the cancer cells are located. Some cancer cells avoid the chemotherapy drugs by means of hiding in several compartments of the body, as in leukemia cells, cancer cells avoid drugs in a way acted as a cover bone.

6. Cancer cells can change form

Cancer cells change shape ' body ' to avoid resistance of the immune system and keep it from chemotherapy drugs and radiation. The cancer cells are in the epithelium, usually changing its shape follows the normal epithelial cells that become the place of growth.

7. Cancer cells always breed

Cancer cells have mutated genes that affect cell reproduction. Normal cells grow by way of splitting into two, then four, and so on. While in cancerous cells, when doing initial cleavage of the resulting cells, double that of normal cells, i.e., four cells then divide again into eight cells, and so on up to very much.

8. Cancer cells require blood flow to survive

One of the signs that the cancer cells undergoing rapid development with the formation of new blood vessels to cancerous tissue, called angiogenesis. A tumor requires nutrients for life and the nutrients carried by blood flow. Cancer cells will send signals to the cells of normal blood flow to give it so that they can also grow. The study mentions that if done the prevention of the formation of blood vessels to cancerous tissue, then the cancer cells will die by itself.

9. Cancer can spread to the entire

Cancer cells can spread or metastasize to different parts of the body through the blood vessels or the lymphatic system. Cancer cell activates a receptor in the blood vessels, which make him could not be removed from the blood vessels and continue to join the flow to all parts of the body. In addition, cancer cells also secrete a substance called chemokine, which serves to hold the immune system, so that they cannot attack while performing the deployment.

10. Cancer cells are hard-wired not to die

Normal cells will die by itself if damaged in his DNA, but it is not the case in cancer cells. Cancer cells do not have the ability to detect and damage do apoptosis (destroying yourself), that they have is merely the ability to multiply themselves as many.
