Because different conditions can look surprisingly similar, appearance alone isn't enough to determine the diagnosis.
Seek medical advice if lesions around the mouth are:
- New and persistent
- Painful or repeatedly bleeding
- Rapidly changing
- Associated with swelling
- Accompanied by fever
- Repeatedly returning without an obvious explanation
Avoid squeezing or picking at unexplained bumps around the mouth, as this can cause irritation or secondary infection.
5. Unexplained Skin Color Changes or Bruising
As people get older, the skin can become thinner and bruises may appear more easily.
Certain medications—including blood thinners and some corticosteroids—can also increase bruising.
But sudden or unusually frequent bruising without a clear explanation deserves medical attention.
Other possible causes include nutritional deficiencies, platelet abnormalities, blood disorders, liver disease, and other medical conditions.
Pay particular attention if bruising occurs together with:
- Frequent nosebleeds
- Bleeding gums
- Blood in urine or stool
- Tiny red or purple spots on the skin
- Persistent fatigue
- Unexplained fever
- Unintentional weight loss
These symptoms do not automatically indicate cancer or another serious disease. They simply mean that a medical evaluation may be appropriate.
6. Changes That Keep Getting Worse
Perhaps the most important warning sign isn't a particular spot, nail pattern, or skin condition.
It is persistence and progression.
A minor change that disappears within a few days is usually different from something that continues to worsen for weeks or months.
