How Does Cancer Start in the Body?

Understanding the Roots of Cancer and Expert Care by Dr. Sumant Gupta in Faridabad

Cancer remains one of the most challenging health concerns of the 21st century. Despite advancements in treatment, the key to fighting cancer lies in understanding how it begins in the body. This knowledge empowers early detection, timely intervention, and the right medical guidance. In this article, we break down the process of how cancer starts in the body and highlight why Dr. Sumant Gupta is considered the best cancer doctor in Faridabad for diagnosis and treatment.

What Is Cancer?

Cancer is not a single disease but a group of related conditions involving abnormal cell growth. Under normal conditions, the human body forms new cells as needed and discards old or damaged ones. In cancer, this orderly process breaks down, leading to the uncontrolled growth of abnormal cells, which may form a mass called a tumor.

Some cancers, like leukemia, do not form solid tumors but instead involve abnormal blood cells circulating through the body.

How Does Cancer Start in the Body?

Cancer begins when the DNA in a cell becomes damaged or mutated. DNA is the instruction manual for every cell. When it malfunctions, the cell may:

  • Grow uncontrollably

  • Avoid natural death (apoptosis)

  • Ignore signals that regulate growth

  • Invade nearby tissues or spread through the bloodstream or lymphatic system (metastasis)

This abnormal behavior is typically triggered by a combination of genetic, environmental, and lifestyle factors.

Causes of Cellular Mutations Leading to Cancer

  1. Genetic Predisposition
    Some individuals inherit gene mutations that increase their risk of cancer. Examples include BRCA mutations linked to breast and ovarian cancer.

  2. Exposure to Carcinogens
    Carcinogens are substances that can cause cancer, such as:

    • Tobacco smoke

    • Radiation (UV or ionizing)

    • Asbestos

    • Certain chemicals and pollutants

  3. Infections
    Certain viruses and bacteria can alter cellular DNA, such as:

    • HPV (linked to cervical cancer)

    • Hepatitis B and C (linked to liver cancer)

    • H. pylori (linked to stomach cancer)

  4. Lifestyle Factors

    • Poor diet

    • Lack of physical activity

    • Obesity

    • Alcohol consumption

    • Chronic stress

  5. Age and Hormonal Changes
    Aging cells accumulate damage over time, and hormonal shifts can stimulate abnormal cell growth.

From Mutation to Tumor Formation

When multiple mutations accumulate in a single cell over time, the body’s defense mechanisms (like tumor suppressor genes) may fail to prevent cancer. As a result, cells continue to divide uncontrollably, forming a tumor.

Tumors can be:

  • Benign: Non-cancerous and do not spread

  • Malignant: Cancerous, aggressive, and capable of spreading to other parts of the body

Why Early Detection Matters

The earlier cancer is detected, the higher the chances of successful treatment and recovery. Common warning signs include:

  • Unexplained weight loss

  • Persistent fatigue

  • Changes in skin or moles

  • Lumps or swelling

  • Chronic pain

  • Changes in bowel or bladder habits
