When the scale needle keeps rising, most people worry about changing body shape, clothes that no longer fit, or getting tired more easily. But few realize that obesity is directly linked to the risk of developing many types of cancer – a fact that scientists have confirmed through numerous research studies.

Why Does Obesity Lead to Cancer?

Our body is like a large ecosystem. When its balance is disrupted by obesity, the effects continue like falling dominoes. There are several key mechanisms that explain this connection.

1. Chronic Inflammation

Fat cells aren’t just storage bags for excess energy. They also release substances that continuously stimulate inflammation. This condition is like a smoldering fire in the body that can damage DNA and accelerate the transformation of normal cells into cancer cells.

2. Increased Hormones

Fatty tissue produces estrogen and insulin hormones. When present in excessive amounts, these can stimulate the growth of certain cells, especially in tissues sensitive to these hormones, such as breast and uterus.

3. Insulin Resistance

Obesity causes the body to respond less to insulin, resulting in higher blood sugar and insulin levels. This is considered a risk factor for developing many types of cancer.

4. Changes in Gut Microbiota

Research has found that obesity affects the balance of bacteria in the intestines, which is related to inflammation and the risk of colon cancer.

Studies from the International Agency for Research on Cancer (IARC) indicate that obesity increases the risk of developing at least 13 types of cancer, including breast cancer, colon cancer, pancreatic cancer, prostate cancer, liver cancer, and many others.

Recognizing Cancer Signs That May Be Related to Obesity

Cancer signs often aren’t obvious in early stages, but there are some signals you shouldn’t ignore, especially if you already have obesity issues:

• Unexplained Weight Loss
  While it might seem like a good thing for someone with obesity, rapid weight loss without intention may be a cancer sign indicating advanced disease.
  
  
• Chronic Fatigue
  Fatigue that doesn’t improve even with adequate rest may be a sign of many types of cancer.
  
  
• Chronic Pain
  Pain that doesn’t go away and can’t be explained by other causes should be thoroughly examined.
  
  
• Non-healing Wounds
  Wounds or lesions that don’t improve within the expected time frame.
  
  
• Changes in Bowel Habits
  Chronic constipation or diarrhea, blood in stool, or significant changes in bowel movement patterns.
  
  
• Night Sweats
  Excessive sweating during sleep that’s not related to room temperature or bedding.

If you experience these cancer signs, especially if you also have obesity, you should consult a doctor as soon as possible. Early diagnosis is crucial for effective treatment.

Reduce Obesity, Reduce Cancer Risk: Simple Methods That Work in Daily Life

Reducing obesity not only makes you look better but also significantly reduces your risk of developing cancer. Here are some simple methods you can implement.

1. Change Your Diet, Don’t Starve Yourself

You don’t need to suffer from hunger. Just make smarter food choices, and your body will thank you.

• Add fresh vegetables and fruits to make up half your plate at every meal.
• Reduce processed foods and sweets.
• Choose unrefined grains like brown rice and whole grain bread.
• Increase quality proteins such as fish, beans, eggs, and tofu.
• Drink water instead of sugary beverages.

2. Move More

Exercise doesn’t just mean heavy gym sessions. Even small movements can have enormous benefits.

• Start with walking 20-30 minutes daily.
• Find opportunities to move in daily life, like parking farther away or taking stairs instead of elevators.
• Find fun activities that involve exercise, such as dancing or swimming.
• Set a timer to get up from your chair every hour if you work sitting down.

3. Get Enough Sleep

Sleep is when your body repairs itself. Chronic sleep deprivation negatively affects hormones and body weight.

• Try to get 7-8 hours of sleep per night.
• Establish good sleep habits, going to bed and waking up at the same time every day.
• Avoid blue light from screens before bedtime.
• Make your bedroom cool, dark, and quiet.

4. Manage Stress

Chronic stress causes the body to release the hormone cortisol, which stimulates appetite and fat accumulation in the abdomen.

• Practice deep breathing or meditation for 10 minutes daily.
• Find relaxing activities not related to food.
• Talk to friends or someone you trust when feeling stressed.
• Get out into nature, even if it’s just a nearby park.

5. Reduce or Eliminate Alcohol

Alcohol not only provides high calories and leads to obesity but also damages the liver and directly increases cancer risk.

• Limit drinking to a minimum, or quit entirely if possible.
• Choose non-alcoholic beverages at social gatherings.
• Find healthy alternative drinks like freshly squeezed fruit juice or herbal tea.

6. Get Annual Check-ups

Cancer screening at appropriate age intervals helps detect and treat it from an early stage.

• Don’t postpone or cancel your annual health check-up.
• Consult with your doctor about cancer screening appropriate for your age.
• Observe abnormalities in your body and see a doctor immediately if you notice cancer signs.
• Follow up on test results continuously.

The good news is that losing just 5-10% of your initial body weight can significantly reduce the risk of cancer and other chronic diseases. You don’t need to be as slim as a model or athlete to have a strong, disease-free body.
