Keloid Size Increase - Causes, Treatment & When to See a Doctor

What is Keloid Size Increase?

A keloid is a type of scar that grows beyond the original boundaries of a wound, often becoming thicker and larger over time. Keloid size increase refers to the unusual expansion or thickening of this scar tissue, which can occur months or even years after the initial injury. Unlike normal scars, keloids are caused by an overproduction of collagen by the body, leading to an abnormal healing response. They are typically painless but may cause cosmetic concerns or physical discomfort if located in areas like the ears, chest, or shoulders.

This condition is often hereditary, with genetic factors playing a significant role. Keloids can vary in size, color, and texture, and they may continue to grow unpredictably. While not life-threatening, uncontrolled size increase can lead to complications such as restricted movement or skin thinning over time.

Key Takeaway: Keloid size increase is not a normal part of healing. If you notice your keloid growing quickly or causing discomfort, consult a healthcare provider promptly.

Common Causes

Keloid size increase can be triggered by various factors. Below are the most common causes:

• Skin injuries or trauma: Cuts, burns, or piercings can lead to keloid formation, especially in individuals predisposed to them.
• Surgical procedures: Minor surgeries or biopsies may result in excessive scar tissue growth in genetically susceptible people.
• Acne scars: Picking at acne lesions or severe acne outbreaks increase keloid risk.
• Hormonal changes: Fluctuations during puberty, pregnancy, or menopause can provoke keloid growth.
• Skin infections: Infections like boils or abscesses may contribute to abnormal scarring.
• Radiation therapy: Previous radiation to the skin can cause keloid formation or expansion.
• Shaving or hair removal: Close shaving or laser hair removal in high-risk areas (e.g., cheeks) is a known trigger.
• Family history: A genetic predisposition increases the likelihood of developing keloids.
• Chronic skin irritation: Repeated friction or pressure on the skin can stimulate keloid growth.
• Certain medications: Long-term use of drugs like isotretinoin (used for acne) may increase keloid risk.

Associated Symptoms

Keloids often develop without symptoms, but when size increases, they may be accompanied by:

• Itching or tingling: Sensory changes as the keloid expands.
• Tenderness or pain: The keloid may become painful as it grows or is irritated.
• Redness or warmth: Inflammation may occur if the keloid becomes infected or is traumatized.
• Thick, rope-like texture: The skin may feel firm or rubbery to the touch.
• Limited mobility: Keloids in areas like the shoulders or neck can restrict movement.
• Cosmetic concerns: Visible growth or asymmetry may affect self-esteem.

If you notice any of these symptoms worsening, seek medical advice to prevent complications.

When to See a Doctor

While small keloids are generally harmless, certain signs indicate urgent medical attention:

• Rapid or out-of-control growth of the keloid.
• Pain, swelling, or warmth around the keloid (signs of infection).
• Bleeding or oozing from the keloid site.
• Difficulty moving a body part due to keloid location.
• Severe itching that interferes with daily activities.
• Cosmetic concerns that significantly impact mental health.

Action Step: Contact a dermatologist or primary care physician immediately if you experience any of the above symptoms. Early intervention is critical to managing keloid growth.

Diagnosis

Diagnosing keloid size increase involves a combination of physical examination and medical history. Dermatologists typically follow these steps:

1. Visual inspection: Examining the keloid’s size, shape, and location. Keloids are usually raised, red, or skin-colored.
2. Patient history: Asking about the initial injury, family history of keloids, or recent trauma to the area.
3. Dermoscopic evaluation: Using a dermatoscope to assess skin texture and rule out other conditions like melanomas.
4. Ruling out infection: Checking for signs of infection (e.g., pus, red streaks) that might mimic keloids.
5. Allergy testing: If keloids appear after new skincare products or medications, allergy evaluations may be done.

In most cases, no blood tests or imaging are needed. However, if infection or cancer is suspected, additional tests may be required.

Treatment Options

Treatment aims to reduce keloid size, prevent further growth, and improve appearance. Options include:

Medical Treatments

• Silicone gel sheeting: Applied daily to flatten and soften keloids. Studies show it can reduce size in some cases (Mayo Clinic, 2023).
• Intralesional corticosteroid injections: Steroid injections directly into the keloid to shrink it. Often combined with other treatments.
• Laser therapy: Pulsed dye lasers or fractional lasers target abnormal blood vessels and collagen. Effective for persistent keloids (Journal of the American Academy of Dermatology, 2022).
• Cryotherapy: Freezing the keloid with liquid nitrogen to reduce size. May cause temporary discomfort.
• Surgical excision: Removing the keloid surgically, though recurrence is common without adjuvant therapy.

Home Remedies (Use with Caution)

• Onion extract or vitamin E oil: Applied topically to reduce inflammation (limited scientific evidence).
• Aloe vera gel: May soothe irritation but does not cure keloids.
• Pressure garments: Wearing tight-fitting clothes over the keloid to exert constant pressure.

Warning: Avoid using unverified home products. Always consult a doctor before trying alternative treatments.

Prevention Tips

While not all keloids can be prevented, these strategies may reduce the risk:

• Avoid unnecessary skin trauma: Minimize cuts, burns, and aggressive shaving.
• Use protective dressings: Cover wounds with silicone-based films to promote proper healing.
• Genetic counseling: Those with a family history should discuss preventive measures with a dermatologist.
• Maintain good skincare: Keep skin clean and moisturized to prevent infections that could trigger keloids.
• Consider prophylactic silicone sheets: For high-risk individuals, start wearing silicone sheets after minor injuries.

Note: Prevention is most effective in individuals without a strong genetic predisposition.

Emergency Warning Signs

Seek immediate medical care if you experience:

• Keloid turning black or necrotic (sign of tissue death).
• Increasing redness spreading beyond the keloid border (possible infection).
• Fever or chills alongside keloid symptoms (systemic infection).
• Sudden, severe pain indicating acute inflammation or thrombosis.
• Difficulty breathing or swallowing if the keloid is near the face or neck.

These signs may indicate complications requiring hospital treatment. Do not delay care.
