Preparing for skin lesion removal

Overview

Skin lesion removal is a minor surgical procedure to take off a mole, cyst, or other growth from your skin. It is often done because the lesion looks suspicious, causes discomfort, or you want it removed for appearance. Preparing properly helps the procedure go smoothly and helps you heal well.

Yes, skin lesion removal is a very common procedure. Millions of people have it done each year for medical or cosmetic reasons.

Anyone with a skin lesion that needs checking or removal can have this procedure. It is more common in people with fair skin, many moles, or a history of sun damage, but it can happen to anyone.

Symptoms

Common symptoms

• A change in an existing mole's size, shape, or colour.
• A new growth that looks different from your other moles.
• A lesion that bleeds, itches, or crusts for no clear reason.
• A sore that does not heal within a few weeks.

Symptoms in children

• Children may have birthmarks or moles that grow as they do. Those that look unusual or change quickly may be removed.
• A mole that becomes painful or bleeds in a child should be checked by a doctor.

Symptoms in older adults

• Older adults often develop new growths like seborrhoeic keratoses (wart-like spots) or actinic keratoses (rough, scaly patches from sun damage). They may need removal if they become irritated or suspicious.
• Any new or changing lesion in an older adult should be evaluated by a doctor.

Causes

Main causes

• Suspicion of skin cancer, such as melanoma or basal cell carcinoma.
• Lesions that are irritated by clothing or cause discomfort.
• Cosmetic reasons – you want it removed for appearance.
• Infection or inflammation that does not go away with treatment.

Risk factors

• Too much sun exposure, especially with sunburns in the past.
• Fair skin that burns easily.
• Having many moles (more than 50) or some unusual-looking moles.
• Family history of skin cancer.
• A weakened immune system (e.g., from medication or illness).

When to see a doctor

See a doctor urgently if:

• If you notice a mole that is changing quickly, has irregular borders, multiple colours, or is larger than 6mm (about the size of a pencil eraser).
• If a lesion starts bleeding, itching, or hurting for no reason.
• If a sore does not heal within four weeks.

Book a routine appointment if:

• For a new growth that you are not worried about but want to have checked.
• For an existing lesion you would like removed for cosmetic reasons.
• As part of a routine skin check if you are at higher risk for skin cancer.

Diagnosis

Your doctor will examine the lesion closely, often using a special magnifying tool called a dermatoscope. If they are unsure or think it may be cancer, they will recommend removing the lesion for testing.

Tests that may be done

• Dermatoscopy – a close-up examination with a magnifying lens.
• Biopsy – removing part or all of the lesion and sending it to a lab to check for cancer cells.
• Sometimes imaging (like ultrasound) if the lesion is deep or under the skin.

What to expect at your appointment

The doctor will talk to you about the lesion and explain why removal might be needed. They will ask about your medical history, allergies, and any medicines you take (especially blood thinners). They will describe the removal process, including anaesthetic and wound care, and answer any questions.

Treatment

The main treatment for a concerning skin lesion is removal. Preparing for removal means following your doctor’s instructions closely to avoid problems like bleeding or infection.

Self-care at home

• Keep the area clean and dry before the procedure.
• Do not apply any creams, makeup, or sunscreen on the lesion on the day of removal.
• If your doctor advises, you may need to stop taking certain medications or supplements that can increase bleeding. Ask your doctor for specific guidance.
• Arrange for someone to drive you home if you will be given sedation; otherwise, you can usually drive yourself.

Medical treatments

The procedure is usually done under local anaesthetic – an injection to numb the skin. The doctor cuts out the lesion and a small edge of healthy skin around it. The wound is often closed with stitches. The removed tissue is sent to a lab for testing. After the procedure, you will get instructions on how to care for the wound (keep it clean and dry, watch for infection signs, and when to come back for stitch removal).

When is surgery considered?

This is a minor surgical procedure. Most skin lesion removals are done in a doctor’s office or clinic. Larger or deeper lesions may need a referral to a specialist surgeon or a hospital day surgery.

Living with this condition

After the removal, keep the wound clean and dry for the first few days. Avoid heavy lifting, stretching, or sweating that could pull on the stitches. Follow your doctor’s advice about when you can shower or bathe. You may have a small scar that fades over time.

Lifestyle tips

• Protect the healing area from the sun to reduce scarring and lower future skin cancer risk.
• Check your other skin lesions regularly for any changes.
• Attend any follow-up appointments to have stitches removed or get biopsy results.

Diet and exercise

A diet rich in fruits, vegetables, and protein can help your wound heal. Gentle exercise is fine, but avoid sports or activities that might rub or injure the healing area until your doctor says it is safe.

Mental health and emotional wellbeing

Waiting for biopsy results can feel stressful. It is normal to worry. If you feel very anxious, talk to your doctor or a counsellor. Having a friend or family member to share your concerns with can also help.

Prevention

Not all skin lesions can be prevented, but you can reduce your risk of developing cancerous skin lesions by protecting your skin from the sun. Use a broad-spectrum sunscreen of SPF 30 or higher, wear protective clothing and a hat, avoid tanning beds, and stay in the shade during peak sun hours. Regularly check your skin for new or changing spots.

Vaccines

There is no vaccine to prevent most skin lesions or skin cancer. However, some viruses like HPV can cause warts and other skin growths, and the HPV vaccine can help prevent those.

Screening programmes

There is no standard screening test for skin cancer. However, if you are at high risk (many moles, family history, fair skin), talk to your doctor about regular skin checks with a dermatologist.

Complications

If left untreated

• A cancerous lesion left untreated may grow deeper and spread to other parts of the body, making it harder to treat.
• A non-cancerous lesion may become irritated, infected, or cause discomfort over time.

Long-term outlook

The outlook for most skin lesions is very good. Even if skin cancer is found, it is often curable when caught early. After removal and proper healing, most people return to their normal activities quickly. Keeping an eye on your skin and seeing a doctor when needed helps keep you healthy.
