Can I Workout After a Skin Biopsy? Managing Activity While Waiting for Results

Getting a skin biopsy can bring up two main concerns: how to care for the biopsy site and the anxiety that comes with waiting for results. If you’re wondering whether you can continue your normal routine—including exercise—and how to manage the days between your procedure and your phone call from the dermatologist, this guide covers what you need to know.

Returning to Exercise After a Skin Biopsy

Can I workout after a skin biopsy? For most patients, the answer is yes—with some sensible precautions.

Light to moderate exercise is usually fine the same day as your biopsy. Walking, stretching, and everyday activities won’t interfere with healing. However, there are a few things to consider:

For the first 48 hours: Keep the biopsy site dry and protected. This means avoiding swimming pools, hot tubs, and activities that cause heavy sweating. If your biopsy is on your leg or arm, high-impact exercises that strain or stretch the area should be postponed for a few days.

After 48 hours: Once you begin changing the bandage daily, you can gradually return to your normal workout routine. Just make sure to cleanse the site and apply fresh petroleum jelly and a clean bandage after exercising.

Listen to your body: If an activity causes pain, pulling, or bleeding at the biopsy site, scale back. Healing takes priority over maintaining your usual fitness schedule.

If you had a punch biopsy with stitches, ask your dermatologist about specific activity restrictions. Stitches may need extra care, and certain movements could delay healing or affect the final appearance of the scar.

How Long Should You Keep a Skin Biopsy Covered?

The initial bandage should stay in place for at least 48 hours. Keeping the site covered and dry during this period protects the wound and allows the earliest stage of healing to begin undisturbed.

After two days, you’ll start a simple daily routine: gently remove the old bandage, clean the area with mild soap and water, apply a thin layer of petroleum jelly, and cover it with a fresh bandage. Continue this for about one week, or until the site has closed and formed a protective layer.

Moist wound care—keeping the biopsy site slightly moist rather than letting it dry out—promotes faster healing and reduces the chance of noticeable scarring.

Skin Biopsy Healing Stages

Understanding the healing process can help set realistic expectations and reduce worry.

Days 1-2: The site may feel tender and show minor redness or swelling. A small amount of bleeding or oozing is normal. The bandage protects the area while initial clotting and tissue repair begin.

Days 3-7: A scab or thin crust usually forms. The surrounding skin may still appear slightly pink. This is the active healing phase, where new skin cells are regenerating beneath the surface.

Weeks 2-3: The scab naturally falls off on its own. The new skin underneath may look pink or lighter than the surrounding area. Avoid picking at the scab—letting it come off naturally minimizes scarring.

Weeks 4 and beyond: The color gradually evens out. Some biopsies leave a small, flat scar that continues to fade over several months. Protecting the area from sun exposure during this time helps prevent darkening or discoloration.

Why Does It Take So Long for Skin Biopsy Results?

One of the most common frustrations patients express is the waiting period. Results typically take 7 to 10 business days, and for many people, this feels like a long time.

Here’s what happens behind the scenes: After your dermatologist removes the tissue sample, it’s sent to a specialized pathology lab. A dermatopathologist—a physician trained to diagnose skin diseases under a microscope—examines thin slices of the tissue that have been processed and stained. This careful analysis takes time because accuracy is essential.

Some cases require additional steps, such as deeper staining techniques or a second pathologist’s review, which can extend the timeline by a few days. Weekends and holidays also affect turnaround time.

While waiting can be difficult, the thoroughness of this process ensures your dermatologist has the most accurate information to guide your care.

Nervous while waiting for biopsy results? 

It’s completely normal to feel anxious while waiting for your results. Many patients describe checking their phone repeatedly, replaying the appointment in their mind, or worrying about what the biopsy might reveal.

A few things to keep in mind during this time:

Most biopsies come back benign. The majority of suspicious moles and lesions turn out to be non-cancerous. Common benign findings include seborrheic keratoses (harmless age-related growths), benign nevi (ordinary moles), and actinic keratoses (precancerous spots that are easily treatable).

Early detection is good news. If the biopsy does identify skin cancer—whether basal cell carcinoma, squamous cell carcinoma, or melanoma—finding it early means treatment is typically straightforward and highly successful.

You’ve already taken the most important step. By getting the biopsy done, you’re being proactive about your health. Waiting for results is part of the process, but you’ve already done the hardest part by seeking evaluation.

Avoid online searching. Every biopsy is unique. Reading about other people’s experiences or trying to self-diagnose based on internet descriptions usually increases anxiety rather than providing clarity.

If the waiting becomes overwhelming, reach out to your dermatologist’s office. A brief conversation with a staff member can often provide reassurance and remind you that help is available if needed.

What Happens Next

Once your results are ready, your dermatologist will contact you using the communication method you selected—phone call, secure message, or follow-up appointment. The reports will explain whether the lesion was benign, precancerous, or malignant, and outline any recommended next steps.  For benign results, the biopsy report may only need to be reviewed at your next scheduled routine appointment.

If treatment is needed, options vary depending on the diagnosis. Non-cancerous findings may require no further action. Precancerous lesions might be treated with cryotherapy or topical medication. Skin cancers like basal cell carcinoma and squamous cell carcinoma are often removed with a simple excision. Melanoma may require more extensive evaluation and treatment, but early-stage melanoma has excellent cure rates.

When to Call Your Dermatologist

While complications after a skin biopsy are rare, contact your dermatologist if you notice:

• Bleeding that doesn’t stop after applying firm pressure for 10-15 minutes
• Increasing pain, redness, or swelling around the biopsy site
• Pus, unusual drainage, or a foul odor
• Fever or red streaks extending from the wound

These signs are uncommon, but it’s always better to check in early if something doesn’t seem right.

Moving Forward

A skin biopsy is a brief procedure with a clear purpose: to give your dermatologist the information needed to protect your health. The days that follow—caring for the site, adjusting your routine, and waiting for results—are manageable with the right information and a little patience.

Stay active within your comfort level, follow the aftercare instructions you received, and remember that most people who undergo skin biopsies receive reassuring results. If concerns arise, your dermatology team is available to help.
