What is Cancer?

Cancer is a condition where abnormal and uncontrollable cell growth occurs and suppresses normal cells. This abnormal growth of cells can form lumps commonly known as tumors. Cancer can appear and grow in any part of the body. It can start from the lungs, breasts, intestines, even blood.

Basically, the human body consists of trillions of cells scattered in each organ and part. Later, these cells will continue to grow and develop into new cells. Since it is replaced, naturally unhealthy, malfunctioning and old cells will die.

While cancer cells will not die by itself. The cell will multiply to an amount that can no longer be controlled. This change that can trigger the appearance of cancer cells. The disease can appear on any part of the body because of its origin from cells in the human body. This answers the question of why there are so many types of cancer. Based on reports and research, there are more than 200 different types of cancer.

What is Cancer Causes?

The main cause of cancer is genetic changes (mutations) in cells. Genetic mutations will make abnormal cells. In fact, the body has its own mechanism for destroying these abnormal cells. If the mechanism fails, abnormal cells will grow uncontrollably.

Factors that can trigger the growth of cancer cells vary depending on the type of cancer. Nonetheless, no specific type of cancer is triggered only by one factor.

Factors that are suspected to be at risk of causing genetic mutations in normal cells and the body’s failure to repair them include:

  • Have a history of cancer in the family.
  • Over 65 years old. However, some types of cancer are more common in children.
  • Smo**ke.
  • Exposure to radiation, chemicals (e.g. Asbestos or benzene), or sunlight.
  • Infected with viruses, such as hepatitis B, hepatitis C, and HPV.
  • Exposure to hormones in high or long-term levels.
  • Obese.
