Myths of Breast Cancer
Myth vs. Truth
Knowing the truth behind common misconceptions can protect you from unnecessary fear and help you stay informed about your health.
The Lump Myth
"A very common myth is that if an individual has a lump, it means that person will get cancer. But that’s not the truth."
Even though a lump can be a sign, not every lump is cancerous, and breast cancer doesn’t always cause a noticeable lump. Misconceptions can delay proper medical care.
