Misconception 5: “It’s dangerous or something that should be removed”
Some people feel self-conscious about the scar and worry it might be unsafe, abnormal, or something that needs medical treatment.
The truth:
The BCG scar is harmless. It does not grow, spread, or turn into a medical problem. There is no medical reason to remove it unless someone chooses to do so for cosmetic reasons.
Doctors generally consider it a normal, benign mark—nothing more than a quiet reminder of early protection.
A Small Scar with a Big Story
For many people, the round scar on the arm is a symbol of a time when medical decisions were made quietly, without explanation. Parents trusted public health systems. Children were protected, but rarely informed.
Today, understanding the truth behind this scar helps remove fear, shame, and misinformation. It is not a flaw, a disease, or a mark of hardship—it is simply a trace of preventive medicine.
Sometimes, the smallest marks carry the longest stories.
