Kenali Risiko dan Penyabab Kanker Sejak Dini

In 2022, Indonesia is confronted with significant health challenges as it ranks eighth in the number of cancer cases in Southeast Asia. The escalating number of cancer cases each year is causing grave concern for both the government and society.


According to the Global Burden of Cancer Study (GLOBOCAN) report, it is estimated that there will be a 47% global increase in new cancer cases, reaching 28.4 million by 2040. In 2020, Indonesia saw a rise of 396,914 new cancer cases, with the following being the five most common types and their respective percentages:


  • Breast cancer: 16.6%

  • Cervical cancer: 9.2%

  • Lung cancer: 8.8%

  • Colorectal cancer: 8.6%

  • Liver cancer: 5.4%


Cancer is a disease that instills fear in many people. The common belief that cancer is hereditary often raises concerns, especially for individuals with family members who have had the disease. However, is this belief accurate? The answer is not straightforward.


What is Cancer?


Cancer is a collection of diseases characterized by uncontrolled cell growth and the spread of abnormal cells. These cells have the ability to invade surrounding tissues and can also spread to other parts of the body through the blood and lymphatic system. Cancer can occur in nearly any part of the body and there are numerous types of cancer, each with its own distinct clinical and molecular characteristics.


Recognize the Symptoms of Cancer


Here are some symptoms of cancer that need to be watched out for, as quoted from the Mayo Clinic journal:


  • Unusual lumps or swelling

  • Persistent or unexplained pain

  • Persistent fatigue

  • Unexplained weight loss

  • Changes in eating habits

  • Changes in bowel or urination habits

  • Unusual bleeding or bruising

  • Wounds that don't heal

  • Hoarseness or persistent cough

  • Difficulty swallowing


It is important to note that:


  • Not everyone with cancer will experience all of these symptoms.

  • Some of these symptoms can also be caused by other, less serious conditions.

  • If you experience any of these symptoms, consult a doctor immediately for proper diagnosis and treatment.


Cancer is a hereditary disease, is it true?


Cancer is a complex disease, influenced by both genetic and environmental factors. Genetic factors can increase a person's risk of developing cancer through mutations in genes that regulate cell growth and division. These mutations can be inherited from parents. Some types of cancer more influenced by genetic factors include:


  • Breast cancer

  • Ovarian cancer

  • Colon cancer

  • Prostate cancer

  • Pancreatic cancer


It's important to note that having a family history of cancer doesn't guarantee that you will develop the disease. In addition to genetic factors, environmental influences also play a significant role in cancer development. These influences include:


  • Smoking

  • Alcohol consumption

  • Sun exposure

  • Chemical exposure

  • Unhealthy diet

  • Lack of exercise


Cancer risk may be influenced by a combination of genetic and environmental factors. Thus, understanding your family history and adopting a healthy lifestyle is important for reducing the risk of developing cancer.

It is important to understand the risks of cancer and how they can be inherited. By making lifestyle changes and implementing effective preventive measures, you can reduce the risk of developing cancer and minimize the possibility of death from the disease. Factors such as maintaining a healthy diet, engaging in regular physical activity, avoiding carcinogenic substances, and undergoing early cancer screenings have been demonstrated to significantly lower the risk of developing cancer. It is essential to maintain regular health check-ups at least once a year through medical services at K-Lab clinic in order to detect potential risks of the disease early and address them promptly.
