“ When Your Body Whispers: Early Signs of Cancer to Watch For!”

 Looking in the mirror one morning, I suddenly wondered, “Is this fatigue just from stress?” “Is this weight loss really the result of dieting?” Our bodies sometimes send quiet, yet unmistakable warning signs. If we ignore them, a disease like cancer could quietly take hold.


Cancer is not simply a matter of genetics or fate. The World Health Organization (WHO) has stated that about 70% of cancer cases are attributed to lifestyle and environmental factors. In other words, the choices we make in our daily lives—our diet, physical activity, alcohol consumption, and smoking habits—have a significant impact on cancer risk.


Recently, the American Association for Cancer Research (AACR) announced that 40% of all cancer cases are linked to modifiable risk factors. Alcohol consumption, in particular, has been identified as a major contributor to cancers such as breast, colon, and liver cancer. Research shows that even one drink a day can increase the risk of oral cancer by five times and liver cancer by 2.2 times.


Environmental pollution is also a factor we cannot ignore. According to the European Environment Agency (EEA), 10% of all cancer cases in Europe are linked to environmental pollution, with air pollution and indoor radon exposure cited as major causes. Radon is known to be the second leading cause of lung cancer, following smoking.

 So what kind of signals might cancer send?

According to the American Cancer Society, the following are some common but easily overlooked symptoms of cancer:

  • Unexplained weight loss
  • Persistent fatigue
  • Difficulty swallowing
  • Unusual bleeding
  • Changes in the skin


These symptoms may occur in everyday life, but if they persist or worsen, it’s important to consult a medical professional.


Preventing cancer requires changes in lifestyle. Quitting smoking, reducing alcohol consumption, maintaining a balanced diet, and engaging in regular physical activity are fundamental. In fact, one study found that people who followed a Mediterranean diet and exercised for 300 minutes per week had a 35% lower recurrence rate of colon polyps.


Efforts to reduce environmental risk factors are also essential—such as using sunscreen, testing for indoor radon, and getting the HPV vaccine. In Singapore, policy-level support includes implementing a health tax on processed meats, which has led to a 15% reduction in meat consumption.


Cancer may approach quietly, but it can be prevented through our small acts of awareness and action. Starting today, let’s pay attention to our body’s signals and commit to healthier habits. Those small changes can lead to big differences in the future.

Many people will feel their hearts sink when they hear the word “cancer.” However, there is also hopeful news. Did you know that thanks to the advancement of modern medicine, there are cancers that have a very high cure rate? Today, I will introduce three types of cancer that have a high possibility of being cured, and I will also talk about actual cases of being cured.   1. Thyroid cancer – Survival rate of over 98% if detected early Thyroid cancer is often called a ‘good cancer’. The reason is because it has a high cure rate. It occurs especially often in women, but if detected early, the survival rate is almost 100%. If you just take hormone medication after surgery, there will be no major inconveniences in your daily life. Actual case: Ms. Kim, a woman in her early 40s, was diagnosed with early-stage thyroid cancer after a detailed examination after discovering a small lump during a health checkup.
