Medical Video: Real Questions - How does radiation kill cancer cell?

Cancer cells are cells whose growth and development are abnormal. Cancer cells have the ability to multiply and multiply as much as possible. Then this group of cancer cells grows into a new tissue called a tumor. The tumor continues to develop along with the development and growth of cancer cells, when this tumor continues to grow without stopping it can be said to be a malignant tumor.

Cancer cells have many differences with normal cells in the body. Not only does it grow aggressively, but cancer cells can also spread to other parts of the body and build new tissue. Cancer cells also cannot die and damage themselves like other normal cells. Here are facts about cancer cells that you might not 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 types of cells. Cancer cells can grow in organs, tissues, and cells. The most common type of cancer is carcinoma. Carcinoma is a cancer cell that grows in the body's epithelial tissue, the tissue that lines various organs, blood vessels, and tissues in the body. While other types of cancer cells are sarcomas. Sarcomas are cancer cells that usually grow in bone tissue, muscles, adipose tissue, glands, tendons, and joints. Leukemia is a type of cancer that grows in the bone marrow that occurs due to white blood cells that grow abnormally. While lymphoma is a cancer caused by the growth of B cells and abnormal T cells in the body.

2. Cancer cells can come from viruses

Cancer cells grow and develop due to several supporting factors such as radiation, exposure to chemicals, ultraviolet light and a failed DNA replication process. But it turns out besides that, cancer cells can also appear due to viruses. Viruses have the ability to cause cancer and are triggered by genetic factors. It is known that 15% to 20% of total cancer cases occur due to viruses. Viruses change DNA in normal cells, so that cells mutate and grow aggressively. The Epstein-Barr virus results in Burkitt's limphoma disease, the hepatitis B virus causes liver cancer, and the human papilloma virus (HPV) can cause uterine cancer.

3. A third of cancer events can be prevented

According to WHO, as many as 30% of cancer events can actually be prevented. Cancer caused by genes or hereditary factors only reaches 5% to 10% of the total cancer cases that exist. The rest, cancer occurs due to various environmental factors, such as infection, pollution, and lifestyle. Prevention that can be done to prevent cancer is prohibiting tobacco use and smoking. Smoking is the main reason for cancer, 70% of lung cancer cases are caused by smoking.

4. Cancer requires high sugar

The more sugar that is eaten by cancer cells, the faster they grow. Sugar is a substance that is needed by normal cells to carry out respiration and then produce energy used to carry out physical activity. Cancer cells need high sugar levels to multiply themselves.

5. Hiding in the body

Cancer cells can hide from the immune system by growing on normal cells. For example, some tumors that grow in the lymph glands secrete proteins, they should also be excreted or secreted by the lymph glands. Therefore, the immune system cannot detect where cancer cells are. Some cancer cells avoid chemotherapy drugs by hiding in several body compartments, such as leukemia, cancer cells avoid drugs by acting as a bone cover.

6. Cancer cells can change shape

Cancer cells change their 'body' shape to avoid resistance from the immune system and guard against chemotherapy and radiation drugs. Cancer cells that are in epithelial tissue, usually change their shape following normal epithelial cells that become the place of growth.

7. Cancer cells always multiply

Cancer cells have mutated genes that affect cell reproduction. Normal cells develop by splitting themselves in half, then into four, and so on. Whereas in cancer cells, when doing the initial division, the cells produced are twice that of normal cells, that is, four cells. Then split itself into eight cells, and so on until it becomes very much.

8. Cancer cells need blood flow to survive

One sign that cancer cells are experiencing rapid development is the formation of new blood vessels for the cancerous tissue, which is called angiogenesis. Tumors need nutrients for life and these nutrients are carried by the bloodstream. Cancer cells will send signals to normal cells to give them blood flow so they can also grow. Research says that if prevention of blood vessel formation is made for cancerous tissue, the cancer cells will die by themselves.

9. Cancer can spread throughout the area

Cancer cells can metastasize or spread to various parts of the body through blood vessels or the lymph system. Cancer cells activate a receptor in a blood vessel, which makes it unable to be removed from the blood vessels and continues to flow to all parts of the body. In addition, cancer cells also release substances called chemokines, which function to hold back the immune system, so they cannot be resisted when spreading.

10. Cancer cells are programmed not to die

Normal cells will die by themselves if they damage their DNA, but not in cancer cells. Cancer cells do not have the ability to detect damage and do apoptosis (self-destruction), all they have is the ability to multiply as much as possible.
