Canker sores vs cancer: When to consider a screening
Canker sores vs cancer, how can you tell them apart? While they share similar symptoms, a usually painless canker sore typically heals on its own within a few weeks—any longer than this is undoubtedly a cause for concern.
My dear patients, I urge you never to wait until it’s too late to get any oral ulcers or cold sores checked out.

They’re pretty common, affecting about 20% of the population. They may appear due to physical trauma, like when you accidentally bite down on your lip or tongue due to diseases (celiac disease, chickenpox, ulcerative colitis) or deficiencies in certain vitamins and minerals.
Let's compare the main characteristics of canker sores vs cancer below:
Characteristics of oral cancer lesions
Appearance: Lumpy, patchy mixture of white and red bruises. While canker sores can bleed from being grazed or poked, bleeding is a more common factor in mouth cancer.
Since cancer cells can cause nerve or blood vessel damage in the mouth, feeling numbness is also really common. Any swelling, pain or stiffness in the jaw can be a sign of oral cancer.
Pain: Mouth cancer sores in their early stages hardly ever cause lingering pain. If you have a pai
