What Are Benign Skin Growths?
Benign skin growths are noncancerous spots, bumps, or lumps that develop on the skin. They are very common and can appear as people age or after sun exposure, skin irritation, or injury.
Many benign skin growths are harmless and do not need treatment. However, some may become irritated, change in appearance, or resemble skin cancer, making medical evaluation important.
Several factors may contribute to benign skin growths, including aging, sun exposure, genetics, hormonal changes, and previous skin injuries. Certain growths, such as keloids, may develop after cuts, burns, or surgical scars.
Symptoms
Benign skin growths can vary widely in size, color, and texture. Some remain stable for years, while others may slowly change over time.
Common signs may include:
- Raised or flat skin spots
- Soft or firm lumps
- Brown, black, red, or flesh-colored growths
- Itching or irritation
- Bleeding or crusting in some cases
- Growths that enlarge or darken over time
How Are They Diagnosed?
Healthcare providers usually diagnose benign skin growths by examining the skin and reviewing any changes over time. They may ask about symptoms, family history, and sun exposure.
If a growth appears unusual or suspicious, a biopsy may be recommended to rule out skin cancer. Providers may also use the ABCDE warning signs to evaluate moles for melanoma:
- Asymmetry
- Border irregularity
- Color changes
- Diameter growth
- Evolving appearance
Early evaluation is important if a mole or skin lesion changes shape, size, or color.
How Are They Treated?
Many benign skin growths do not require treatment unless they become painful, irritated, or cosmetically bothersome. Treatment depends on the type of growth and whether cancer needs to be ruled out.
Treatment options may include:
- Monitoring the growth over time
- Surgical removal
- Freezing with liquid nitrogen
- Corticosteroid injections
- Laser therapy
- Electrodessication
Most procedures are performed in an outpatient setting and recovery is usually straightforward.
