“ Everything You Need to Know About Thyroid Cancer”

 

What Is Thyroid Cancer?

Thyroid cancer starts in your thyroid gland, a small, butterfly-shaped organ in the neck. Papillary and follicular types (differentiated thyroid cancers) account for most cases and boast excellent survival rates—over 99% five-year survival for papillary type.


Why Are Diagnoses Rising?

Incidence skyrocketed between the 1970s and 2009, primarily due to more imaging and needle biopsies detecting small nodules that may never cause problems  . Though rates stabilized after 2009, overdiagnosis remains a pressing concern  .

Modern Diagnostic Tools

Advanced ultrasound imaging, radiomics, molecular testing, and AI are enhancing accuracy. A 2024 review found AI improved diagnostic precision but still needs standardization.


Cutting‑Edge Treatments

  • CAR‑T cell therapy (AIC100) showed promising early results in aggressive thyroid cancers like anaplastic and poorly differentiated types, achieving tumor control for over half of patients.
  • Targeted and immunotherapy combinations, especially those addressing BRAF mutations, doubled median survival in anaplastic cases from 5 to 19 months.
  • RET‑inhibiting drugs—such as selpercatinib and pralsetinib—are FDA-approved for advanced RET-mutated thyroid cancers.

Who’s at Higher Risk?

People with genetic syndromes (e.g. MEN2), family history, or past radiation exposure are more at risk. GLP‑1 diabetes meds (Ozempic/Wegovy) are linked to more thyroid scans—not cancer—due to increased screening.


Key Takeaways

Thyroid cancer is often treatable—especially papillary and follicular types.

Overdiagnosis from imaging can lead to unnecessary treatment.

New molecular and immunotherapies offer hope for advanced cases.

If diagnosed, discuss active surveillance vs. surgery based on risk.

“ 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“

Image
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 ...

Eating Well After a Cancer Diagnosis: A Gentle, Korean-Inspired Approach After a cancer diagnosis, even something as simple as a meal can feel overwhelming. You may find yourself constantly wondering what’s safe to eat, what to avoid, and how best to nourish your body during recovery. That’s why today, I’d like to introduce a balanced, Korean-style diet tailored to support cancer patients—one that eases the burden on your body while gently supporting your healing process. Choosing the Right Ingredients The key is to keep things gentle and non-irritating. Avoid overly spicy or salty foods, and focus on fresh, seasonal vegetables and clean sources of protein. Here are some particularly beneficial ingredients for cancer patients: Tofu, beans, fish – Gentle sources of protein that are easy on the body Broccoli, spinach, seaweed – Rich in antioxidants and help boost the immune system Brown rice, barley – Packed with dietary fiber to support digestion Perilla oil, ses...
