“ Throat Cancer: A Warning in Your Voice”

What Is Throat Cancer and Who Is at Risk?

Throat cancer refers to malignancies that occur in the pharynx (throat) and larynx (voice box), most commonly affecting men over 50. Risk increases significantly for smokers and heavy drinkers.

According to the World Health Organization (WHO), around 95% of laryngeal cancers are squamous cell carcinomas, which originate from the mucosal lining.

Recent studies also highlight HPV (human papillomavirus) infection as a significant risk factor, meaning even younger people need to be vigilant.


If you or a family member has a history of cancer, or if you’ve experienced hoarseness, sore throat, or difficulty swallowing for more than three weeks, consider getting screened.

Early Detection Saves Lives

When detected early, the 5-year survival rate for throat cancer can reach 80%. However, once the cancer progresses, survival drops to less than 50%.

Korea’s National Cancer Center recommends laryngoscopic screening every 1–2 years for individuals over 40 who smoke or drink.


The American Cancer Society recently reported that endoscopy with Narrow Band Imaging (NBI) is effective for early diagnosis. This technique enhances visualization of microvascular patterns around cancerous tissue, improving detection accuracy.


A visit to an ENT clinic is all it takes. The procedure lasts 10–15 minutes, requires no anesthesia, and is virtually painless.

Practical Prevention Tips to Start Now

  1. Quit Smoking and Reduce Alcohol Consumption: Smokers are over 15 times more likely to develop laryngeal cancer than non-smokers. The risk increases dramatically when smoking and drinking are combined.
  2. Consider HPV Vaccination: Both men and women in their 30s and 40s should consider the HPV vaccine, which not only helps prevent cervical cancer but may also reduce the risk of throat cancer.
  3. Protect Your Throat Health: Avoid irritating foods, limit excessive voice use, and maintain optimal indoor humidity to reduce mucosal irritation.
  4. Regular Screening: Even in the absence of symptoms, a screening every 1–2 years could save your life.

If your profession involves frequent voice use (e.g., teachers, lecturers), it’s crucial to monitor symptoms closely and act early.


Early Screening Is the Best Treatment

Throat cancer often begins with vague symptoms, making it easy to overlook. But early detection dramatically improves treatment outcomes and survival rates.

Today, take the first step in protecting your voice by scheduling a screening.

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

Image
  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 a...

“ Cancer with the highest cure rate in modern medicine“

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. She underwent surgery right away and was discharged from the hospital after ...
