A PET scan (positron emission tomography) is a type of imaging test that uses a radioactive tracer to look for changes in the function of cells and tissues. A tracer is a substance that is introduced into the body to make it easier to see certain areas or organs. The radioactive tracer used in PET scans emits positrons, which are tiny particles that collide with electrons in the body. This creates gamma rays that can be detected by a scanner and used to create images of the inside of the body. PET scans are often used to diagnose cancer because tumor cells typically have higher levels of activity than normal cells. They can also be used to check for treatment response, measure tumor size, and identify new tumors.

PET Scan is a nuclear medicine imaging test that uses a small amount of radioactive material, called a tracer, to look for disease in the body. A PET Scan can show how well organs and tissues are working. It can help find cancer, heart problems, and other diseases. A Positron Emission Tomography (PET) scan is a medical imaging test that helps physicians diagnose and treat diseases. PET scans use a small amount of radioactive material, called a tracer, to help physicians see how organs and tissues are functioning. The radioactive tracer is injected into the patient's body and travels to the organ or tissue being studied. Physicians can then see where the tracer collects on an image of the organ or tissue.

A PET scan is helpful in diagnosing cancer, heart disease, brain disorders, and other diseases. It can also help determine how well treatment is working. PET Scan is an acronym for Positron Emission Tomography. It's a type of medical imaging that uses a small amount of radioactive material to help diagnose and treat medical conditions. A PET scanner creates 3D images of the inside of the body. PET (positron emission tomography) scans use a small amount of radioactive material called a tracer to help doctors see certain areas of the body. The tracer is injected into a vein, and images are taken as it moves through the body.

PET scans are often used to find cancer because tumors absorb more of the radioactive material than normal tissue does. PET scans can also be used to measure blood flow, check how well drugs work, and see how active the brain is. A PET scan is a type of imaging test that uses radioactive tracers to look at the function and structure of organs and tissues in your body. A small amount of radioactive material is injected into your bloodstream and then scanned by a special camera. The camera creates pictures that show where the material has collected. This can help doctors see how well an organ is working or find tumors or other problems.

PET scan is short for positron emission tomography. It's a type of medical imaging that uses a radioactive tracer to look at organ function or tissue metabolism. The tracer is a small amount of radioactive material that's injected into the patient's bloodstream. It collects in organs and tissues, and a scanner detects the radiation emitted as it decays. This information is used to create cross-sectional images of the body that show how the organs and tissues are working. PET scans are most often used to detect cancer because tumors consume more energy than normal tissue and therefore have a higher metabolic rate. But they can also be used to evaluate other problems, such as heart disease, brain function, and joint damage.

PET scanning is a type of nuclear medicine imaging. A small amount of radioactive glucose (FDG) is injected into a vein and images are taken as the glucose moves through the body. Cancer cells use more energy than normal cells and therefore absorb more of the radioactive glucose. This allows tumors to be visualized on the scan. PET stands for Positron Emission Tomography. A PET scan is a medical imaging test that uses a radioactive tracer to look at organs and tissues inside the body. The tracer is injected into a vein, and images are taken as it moves through the body.

Lifestyle Disease Prevention India: Protecting Health Through Proactive Care

Lifestyle Disease Prevention India: Protecting Health Through Proactive Care

Lifestyle diseases, also known as non-communicable diseases (NCDs), have become one of India’s most pressing health challenges. Conditions such as diabetes, hypertension, obesity, heart disease, thyroid disorders, fatty liver, and high cholesterol now affect millions-often starting at younger ages compared to previous generations. According to the Indian Council of Medical Research (ICMR), NCDs account for more than 60 percent of deaths in India. The good news: most lifestyle diseases are preventable with awareness, screening, and timely intervention.

SecondMedic supports a national shift from reactive to preventive healthcare through early detection, nutrition planning, lifestyle improvement, and chronic risk monitoring.

Why Lifestyle Disease Prevention Matters in India

1. Rising NCD Burden

Rapid urbanization, longer working hours, stress, and processed foods have accelerated lifestyle disease growth.

2. Younger Population at Risk

More Indians in their 20s and 30s are developing prediabetes, fatty liver, and high cholesterol.

3. Silent Disease Progression

Many conditions show no symptoms in the early stages.

4. High Long-Term Medical Cost

Treatment for advanced diabetes or heart disease is expensive compared to prevention.

5. Impact on Productivity

Organizations face rising health-related absenteeism and reduced performance.

Prevention is not optional-it is a necessity.

Major Lifestyle Diseases in India

1. Diabetes & Prediabetes

India has over 10 crore diabetics, with many unaware of their condition.

2. Hypertension

Known as the “silent killer,” it increases risk for heart attack and stroke.

3. Heart Disease

India sees one of the highest premature heart attack rates globally.

4. Obesity & Metabolic Syndrome

Poor diet and inactivity contribute to dangerous fat accumulation.

5. Fatty Liver Disease

Highly common even among non-alcoholic individuals.

6. Thyroid Disorders

Thyroid imbalances affect metabolism, weight, and mental health.

7. Stress & Sleep Disorders

Impact emotional stability and long-term health.

SecondMedic offers preventive screenings tailored for each of these risk areas.

Early Detection Through Preventive Health Checkups

Preventive checkups help detect abnormalities before they turn into chronic disease.

SecondMedic’s packages include:

  • CBC
     

  • Lipid profile
     

  • HbA1c
     

  • Thyroid panel
     

  • Liver function tests
     

  • Kidney profile
     

  • Cardiac markers
     

  • Vitamin D & B12
     

  • Hormone tests
     

  • ECG
     

These tests provide a comprehensive health snapshot.

Lifestyle Disease Prevention Strategies

1. Nutrition Management

A healthy diet is the foundation of prevention.
SecondMedic dietitians design personalized nutrition plans based on:

  • Age
     

  • Weight
     

  • Activity
     

  • Medical history
     

2. Regular Physical Activity

  • Sleep routines
     

4. Avoiding Tobacco & Alcohol

These significantly increase risk of cancer, fatty liver, and heart disease.

5. Healthy Weight Maintenance

Targeted routines help maintain optimal BMI and waist circumference.

6. Adequate Sleep

Poor sleep leads to hormonal imbalance and weak immunity.

7. Regular Health Checkups

Monitoring every 6-12 months helps track changes early.
