Cancer can feel overwhelming, but understanding the basics—what causes it, how it starts, early signs, and treatment options—can help you make informed decisions. If you’re concerned about symptoms or need expert advice, consulting a trusted cancer specialist in Lucknow, such as Dr Harshvardhan Atreya, can give you clarity and guidance.
What Is Cancer?
Cancer occurs when abnormal cells grow uncontrollably in the body. Instead of dying when they should, these cells continue to divide and may form tumors or spread to other areas of the body. Because cancer can start in any tissue, it includes many diseases—not just one.
What Causes Cancer?
Cancer often develops due to damage in the DNA of cells. Several factors can contribute:
- Lifestyle choices like smoking, alcohol, poor diet, and inactivity
- Environmental triggers such as pollution or chemical exposure
- Chronic infections
- Age and genetics
Usually, no single cause is responsible—cancer results from multiple risk factors interacting.
Who Is Most at Risk for Cancer?
Risk increases with:
- Age
- Smoking or alcohol use
- Obesity and lack of exercise
- Exposure to pollutants or harmful chemicals
- Family history
- Chronic illnesses
Even so, many people with risk factors never develop cancer, and some with no known risks do.
Is Cancer Preventable?
You can reduce cancer risk significantly by:
- Avoiding tobacco
- Eating healthier
- Exercising regularly
- Limiting alcohol
- Protecting skin from UV exposure
- Managing chronic conditions
- Getting recommended screenings
Prevention doesn’t guarantee protection, but it lowers your risk dramatically.
What Are the Early Signs of Cancer?
Watch for:
- Unexplained weight loss
- Chronic fatigue
- Lumps or swelling
- Skin changes
- Persistent cough or throat issues
- Changes in bowel or bladder habits
- Unusual bleeding
These symptoms don’t always mean cancer, but persistent issues should be checked by a cancer doctor in Lucknow or your local area.
How Is Cancer Diagnosed?
Doctors may use:
- Medical history and physical exams
- Imaging tests like MRI, CT scan, or X-ray
- Blood tests
- Biopsies
Accurate diagnosis helps determine the best treatment plan.
What Are the Main Treatment Options?
Common treatments include:
- Surgery
- Chemotherapy
- Radiation therapy
- Immunotherapy
- Targeted therapy
- Hormone therapy
Treatment often involves a combination for best results.
Is Cancer Curable?
Some cancers are highly curable when detected early. Others may be managed long-term or controlled with ongoing treatment. Early detection greatly improves outcomes.
Does Family History Mean I Will Get Cancer?
Not necessarily. Only a small percentage of cancers are hereditary. Lifestyle, environment, and random mutations play a much bigger role. Still, those with strong family history should consult an oncologist for personalized guidance.
How Can I Reduce My Cancer Risk?
The most effective steps include:
- Staying active
- Eating whole, nutritious foods
- Avoiding tobacco
- Limiting alcohol
- Getting regular health screenings
- Managing stress
- Seeing a doctor for persistent symptoms
If you’re in Lucknow, consulting an oncologist like Dr Harshvardhan Atreya can help you understand your personal risk.

Can stress cause cancer?
Stress alone doesn’t cause cancer, but unhealthy coping habits may increase risk.
What is a benign vs. malignant tumor?
Benign tumors are non-cancerous; malignant tumors are cancerous and can spread.
When should I consult a cancer doctor?
If symptoms are persistent, unusual, or unexplained, seek medical evaluation.
