My Family Has a History of Skin Cancer—How Often Should I Have My Moles Checked?

by: Dr. Ashley Baldree

When skin cancer runs in the family, even harmless-looking moles and spots can create understandable concern. Many patients wonder whether they should have their skin checked more often, what changes they should watch for, and whether every new growth needs to be removed.

Recently, a 32-year-old woman visited Village Dermatology for a comprehensive evaluation of skin lesions throughout her body. She also wanted education about sun exposure and evaluation for any suspicious growths.

Her personal history was reassuring—she had no previous skin cancer—but she did have a family history of non-melanoma skin cancer.

Her visit raised an important question:

“My family has a history of skin cancer—how often should I have my moles checked?”

A complete skin examination was performed using dermoscopy. The good news was that no suspicious lesions were identified during this visit.

Several common benign findings were documented, including benign moles and lentigines. One mole on the right upper back was photographed for future comparison. She was also treated for several contagious warts on her right hand with liquid nitrogen.

For patients searching for a skin cancer screening or mole check in Houston or Katy, Texas, this case shows how routine dermatologic surveillance can help establish a baseline and monitor changes over time.

Does a Family History of Skin Cancer Mean I Will Get Skin Cancer?

Not necessarily.

A family history can be one factor a dermatologist considers when discussing skin surveillance, but it does not mean that skin cancer is inevitable.

In this patient's case, her examination showed no suspicious lesions.

Because of her family history of non-melanoma skin cancer, she was advised to be especially consistent with:

  • Broad-spectrum sunscreen

  • Sun-protective clothing

  • Monthly self-skin checks

  • Monitoring new or changing growths

  • Seeking evaluation for lesions that do not heal

The goal is awareness and early evaluation of suspicious changes.

What Happens During a Full-Body Skin Examination?

A comprehensive skin examination looks beyond the one or two spots a patient may already be worried about.

For this patient, the examination included the:

  • Scalp

  • Face

  • Ears

  • Neck

  • Chest

  • Abdomen

  • Back

  • Arms

  • Legs

  • Breasts

  • Hands

  • Feet

  • Groin

  • Buttocks

  • Genital region

  • Fingernails and toenails

A dermatoscope was used to examine skin lesions in greater detail.

This type of evaluation allows the dermatologist to document existing lesions and identify anything that may need closer monitoring.

Were Any of Her Moles Suspicious?

No findings concerning for malignancy were identified during the visit.

The patient's nevi, or moles, appeared as regular, symmetrical, evenly colored macules and papules, which supported their benign appearance.

One mole on the right medial upper back measured approximately 0.4 × 0.4 cm.

Rather than removing it, the plan was to:

  • Observe it

  • Photograph it

  • Compare it at future visits

This is an example of how dermatologists may monitor a benign-appearing mole rather than automatically biopsy or remove it.

Why Take a Photo of a Mole?

Clinical photographs can be helpful for future comparison.

If a mole looks benign today but deserves observation, a photograph provides a visual baseline that can help determine whether it changes over time.

Changes in:

  • Size

  • Shape

  • Color

  • Surface appearance

may be easier to recognize when a previous image is available.

This patient's right upper-back mole will be monitored at future examinations.

What Changes in a Mole Should I Watch For?

Patients were advised to perform monthly self-skin checks.

Contact a dermatologist if a mole:

  • Changes in size

  • Changes in shape

  • Changes in color

  • Begins itching

  • Starts burning

  • Bleeds

  • Looks significantly different from surrounding moles

New growths that enlarge, become painful, or fail to heal should also be evaluated.

What Are Lentigines?

The patient's examination also showed lentigines, which are flat tan or brown spots commonly associated with sun exposure.

These were distributed in sun-exposed areas throughout the body.

Lentigines are benign and do not require treatment.

However, they are a visible sign of cumulative sun exposure, so sun protection was emphasized.

How Much Sunscreen Should I Use?

The patient received detailed sunscreen counseling.

A broad-spectrum sunscreen with SPF 30 or higher was recommended.

General instructions included:

  • Apply sunscreen at least 15 minutes before sun exposure

  • Reapply approximately every 2 hours

  • Reapply sooner after swimming or heavy sweating

  • Use about one ounce for exposed body skin

  • Use lip balm with sunscreen

  • Wear sun-protective clothing when appropriate

Consistent sun protection can help reduce additional ultraviolet damage.

What Were the Growths on Her Right Hand?

In addition to her skin cancer screening, the patient had several verruca vulgaris, commonly known as warts, on her right hand.

They involved areas including the:

  • Right middle finger

  • Right small finger

  • Right thumb

  • Web space of the hand

Because warts are caused by a viral infection, they can be contagious and spread through direct contact.

Several lesions were treated during the visit.

How Are Hand Warts Treated?

A total of four wart lesions were treated with liquid nitrogen cryotherapy using two freeze-thaw cycles.

Cryotherapy freezes the affected tissue and may cause temporary:

  • Redness

  • Blistering

  • Crusting

  • Scabbing

  • Tenderness

Potential risks discussed included pigment changes, scarring, infection, recurrence, and incomplete removal.

The patient was scheduled to return in approximately four weeks for reevaluation.

If the warts improved significantly, she was told she could cancel that appointment and continue over-the-counter wart treatment until they fully resolved.

Can Warts Come Back After Liquid Nitrogen?

Yes.

Warts may require more than one treatment session, and recurrence is possible.

Other wart treatment options can include:

  • Salicylic acid

  • Retinoids

  • Imiquimod in selected circumstances

  • Additional cryotherapy

The most appropriate approach depends on the number, size, location, and persistence of the lesions.

Patients should contact the office if warts continue to spread or repeatedly return despite treatment.

Why Is Monthly Self-Examination Important?

Even after a reassuring professional exam, new skin lesions can develop between appointments.

Monthly self-checks help patients become familiar with their normal skin.

Pay particular attention to growths that:

  • Are new

  • Change over time

  • Fail to heal

  • Bleed repeatedly

  • Become painful

  • Look noticeably different from other spots

For patients with a family history of skin cancer, this habit can be especially useful.

When Should I Schedule a Skin Cancer Screening?

Consider a dermatology evaluation if you have:

  • A personal history of skin cancer

  • A family history of skin cancer

  • Numerous moles

  • A changing mole

  • A new or unusual growth

  • A lesion that will not heal

  • Significant cumulative sun exposure

  • A spot that repeatedly bleeds or crusts

  • A mole you cannot easily monitor yourself

Even when no suspicious lesions are found, the examination can provide a baseline for future comparison.

Skin Cancer Screening and Mole Checks in Houston and Katy, Texas

This 32-year-old patient's examination provided reassuring findings.

Despite her family history of non-melanoma skin cancer, no suspicious lesions were identified during her visit.

Her existing moles appeared benign, and one mole on the right upper back was photographed and documented for future monitoring. She also received counseling on monthly self-examinations and broad-spectrum sun protection.

At the same visit, several contagious warts on her right hand were treated with liquid nitrogen.

If you are concerned about a family history of skin cancer, changing moles, new growths, or unexplained skin lesions, a comprehensive dermatologic examination can help determine what requires treatment and what can safely be monitored.

Patients searching for a skin cancer screening in Houston, Texas, mole check in Katy, Texas, or evaluation of changing skin lesions can schedule an appointment with Village Dermatology.
