Understanding Cancer
A Disease of Uncontrolled Cells
What is Cancer?
Cancer occurs when abnormal cells in the body grow uncontrollably and interfere with normal functions. Unlike healthy cells, these do not die when they should and may spread to other parts of the body.
How Does Cancer Start?
Most cancers begin due to genetic mutations in a single cell. These changes may be triggered by aging, environment, lifestyle, or heredity—and lead to rapid, unchecked growth of harmful cells.
There are over many types of cancer classified by the organ or tissue they begin in, such as:
Cancer Signs
- Unexplained weight loss
- Persistent fatigue
- Lumps or swelling
- Changes in stool & urination
Cancer Stages
- Stage 0: Pre-cancerous
- Stage 1–2: Localized
- Stage 3: Regional spread
- Stage 4: Distant spread
Cancer Causes
- Tobacco and alcohol
- Poor diet and inactivity
- Infections
- Family history
Treatment Overview
- Immunotherapy
- Surgery
- Chemotherapy
- Radiation
When to see a Doctor?
Cancer can often begin silently, with symptoms that may seem minor or unrelated. If you experience unexplained weight loss, persistent fatigue, lumps, prolonged cough, or any unusual changes in your body that don’t resolve over time, it’s essential to consult a healthcare professional.
Early consultation leads to early diagnosis—and early diagnosis saves lives. Don’t ignore signs or delay a check-up. If something feels “off,” trust your instincts and speak to a doctor. Timely action can make a significant difference in treatment outcomes.
