π Quick Breakdown
Cancer usually no just appear suddenly. E dey start when changes happen inside d normal body cell.
D changes dey affect d DNA wey dey control how cells suppose grow, divide and die (d normal cell cycle).
These changes fit gradually gather over time until some cells begin multiply without normal control.
ππΎ Understanding how cancer dey develop help explain why prevention, screening and early detection dey important.
π§ How normal body cell dey work?
Your body get plenty plenty (trillions) of cells, and each one get instructions wey help control wetin e suppose do.
Normally:
• old or damaged cells dey die when their time reach
• new cells dey replace them when e dey necessary
• d body get systems wey dey repair some DNA damage
Dis balance dey help tissues and organs to work properly.
ππΎ Healthy cells no just dey grow anyhow—d body get plenty checkpoints wey dey control them.
π§ Wetin begin change when cancer dey develop?
Inside every cell, d DNA dey carry instructions wey control how that cell behave.
When DNA changes wey no suppose happen, con happen:
• d cell fit continue to grow when e suppose stop
• d damaged cell fit refuse to die
• d cells fit continue to dey produce more abnormal cells
At first, d body fit still repair or remove some of these damaged cells.
ππΎ Cancer usually dey develop when several of d "bad" changes gather together and d normal control systems stop to dey work properly.
π§ Where these changes dey come from?
Different things fit damage or change d DNA.
• Mistake during normal cell division
→ anytime cells divide, small errors fit happen naturally.
• Harmful exposure
→ tobacco smoke, too much ultraviolet radiation and some chemicals fit damage d DNA.
• Changes wey person inherit
→ some people dey born with genetic changes wey increase their chance of developing certain cancers.
ππΎ DNA change no automatically mean cancer. Your body dey successfully repair plenty DNA damage every day.
π§ How you go know say e dey happen?
For d early stage, person fit no notice anything at all.
As abnormal cells continue to grow, some people fit later notice:
• new lump or swelling
• unusual bleeding
• weight loss wey person no fit explain
• unusual tiredness
• some change for how some part of d body normally dey work
→ e.g your toilet/bowel habit change
ππΎ No be every cancer dey show early symptoms, and these symptoms fit also come from conditions wey no be cancer.

Because dem discover am early, doctors discuss treatment while d problem still dey easier to manage.
After e understand, e decide to:
• complete d recommended treatment
• attend follow-up appointments
• continue d recommended screening
ππΎ Mr Etim no wait until serious symptoms appear before doctors discover d abnormal changes.

π§ π©Ί When you suppose go hospital π¨
• new lump wey no disappear
• unexplained bleeding
• unexplained weight loss
• unusual symptom wey continue or dey worsen
ππΎ These symptoms no automatically mean cancer, but early medical assessment important.
π’ Final Reassurance
Cancer development usually involve several changes wey happen gradually inside cells.
One DNA change no mean say person automatically get cancer.
ππΎ You no fit control every cancer risk, but healthy choices, recommended screening and early medical assessment fit make important difference o.
