“ The most common female cancers in the world”

 

  As of 2024, the top three cancers affecting women globally are breast, lung, and colorectal cancers. These cancers account for over half of all new cancer diagnoses in women. Let’s explore why these cancers are so prevalent, their risk factors, and how to prevent and treat them.

1. Breast Cancer

  Breast cancer is the most common cancer among women worldwide, with approximately 2.3 million new cases in 2022.  Its high incidence is influenced by factors such as aging populations, hormonal influences, and lifestyle changes. Risk factors include early menstruation, late menopause, having children later in life or not at all, obesity, alcohol consumption, and physical inactivity. Genetic mutations, particularly in the BRCA1 and BRCA2 genes, also significantly increase risk. 

  Prevention and Treatment: Regular screening through mammography can detect breast cancer early, improving treatment outcomes. Lifestyle modifications like maintaining a healthy weight, limiting alcohol, and engaging in regular physical activity can reduce risk. For those with BRCA mutations, preventive measures may include enhanced surveillance, chemoprevention, or prophylactic surgery. 


2. Lung Cancer

  Lung cancer is the second most common cancer in women, with around 909,000 new cases in 2022.  Historically more prevalent in men, lung cancer rates in women have risen due to increased tobacco use and exposure to secondhand smoke. Other risk factors include exposure to radon gas, air pollution, and occupational hazards.

  Prevention and Treatment: The most effective prevention is to avoid smoking and exposure to tobacco smoke. Regular health check-ups and awareness of symptoms can lead to earlier diagnosis. Treatment options include surgery, chemotherapy, radiation therapy, and targeted therapies, depending on the cancer’s stage and genetic makeup.

3. Colorectal Cancer

  Colorectal cancer ranks third among women, with approximately 857,000 new cases in 2022.  Its incidence is increasing among younger adults, possibly due to dietary habits, obesity, and sedentary lifestyles.  High consumption of processed and red meats, low fiber intake, and alcohol use are notable risk factors.

  Prevention and Treatment: Screening methods like colonoscopy can detect precancerous polyps, allowing for early intervention. Adopting a diet rich in fruits, vegetables, and whole grains, along with regular physical activity, can lower risk. Treatment typically involves surgery, chemotherapy, and, in some cases, radiation therapy.

  Understanding the risk factors and early detection methods for these cancers is crucial. Lifestyle choices play a significant role in prevention, and regular screenings can lead to early diagnosis and better outcomes.

“ 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 ...
