Skin cancer removal surgery is one of the most common surgical procedures carried out in Australia every year, which isn’t surprising given how much sun exposure most of us get over a lifetime.
If your GP or dermatologist has found a suspicious spot, or you’ve been referred for a biopsy that came back abnormal, it’s natural to feel a bit anxious about what happens next.
This article explains, in plain language, the two main surgical approaches used to remove skin cancers in Australia: excision and Mohs surgery.
It also covers recovery, costs, and how Medicare and private health insurance fit in. This is general information only, not personal medical advice. If you are ever experiencing a medical emergency, call 000 or go to your nearest emergency department rather than relying on an article like this one.
What Is Skin Cancer Removal Surgery?
Skin cancer removal surgery involves cutting out a cancerous or pre-cancerous lesion, along with a small margin of healthy-looking skin around it. The aim is to remove all of the abnormal cells so the cancer doesn’t return in that spot.
It’s typically performed as day surgery under local anaesthesia, meaning you’re awake but the area is numbed, and you go home the same day. Larger or more complex cases may need a short hospital stay or a general anaesthetic, which your surgeon will discuss with you beforehand.
Mohs Surgery vs Excision: The Two Main Approaches
Most skin cancers in Australia are treated with one of two techniques. Both are well established and regularly performed by AHPRA-registered doctors, but they suit different situations.
Excision Surgery Explained
A standard excision is the most common approach. The surgeon removes the visible lesion plus a predetermined margin of surrounding skin, then closes the wound with stitches. The tissue is sent to a laboratory afterwards to confirm the margins are clear of cancer cells.
This is usually a quicker, single-visit procedure and is well suited to many common skin cancers, particularly on the trunk or limbs where a larger margin isn’t a cosmetic concern.
Mohs Surgery Explained
Mohs surgery is a more precise, staged technique often used on the face, ears, or other areas where preserving healthy tissue really matters. The surgeon removes a thin layer of tissue and examines it under a microscope on the spot, before you leave the chair.
If cancer cells remain, another thin layer is taken from that exact area only, and the process repeats until the margins are clear. This tends to remove less healthy tissue overall, though appointments can run longer because of the waiting between layers.
Who Might Need Skin Cancer Removal Surgery?
Surgery is generally recommended after a GP or dermatologist identifies a suspicious lesion, often confirmed with a biopsy first. You may then receive a surgical referral to a specialist surgeon or dermatologist with surgical training.
Organisations such as Cancer Council Australia provide helpful, evidence-based information on the different types of skin cancer and when surgical treatment is typically considered.
Not every mole or spot needs surgery. Your GP is the right first point of contact, and they will let you know if a referral for further assessment or treatment is appropriate for your situation.
Surgical Risks and What Recovery Looks Like
Like any surgical procedure, skin cancer removal carries some general surgical risks. These are usually discussed with you as part of the informed consent process before your operation.
- Bleeding, bruising, or infection at the wound site
- Scarring, which varies depending on the size and location of the lesion
- Temporary numbness or altered sensation near the wound
- A small chance the cancer isn’t fully removed, requiring further surgery
- Reactions related to local or general anaesthesia
Most people recover well within one to two weeks for smaller excisions, though healing time depends on the size and location of the wound. Your surgical team will give you specific instructions to follow at home.
Caring for Your Wound After Surgery
Post-operative wound care usually involves keeping the area clean and dry, following dressing change instructions, and watching for signs of infection such as increasing redness, swelling, or discharge. Some people also see a nurse or allied health practitioner during recovery.
Always follow the specific advice given by your surgeon or their team, as wound care can vary depending on where the surgery was performed and how it was closed.
Medicare, Private Health Insurance and the Cost of Skin Cancer Removal Surgery
Medically necessary skin cancer removal surgery is generally eligible for a Medicare rebate when performed by an appropriately qualified practitioner, though out-of-pocket costs can still apply depending on how the service is billed. You can check current rebate details through Services Australia.
If you’re treated in the public hospital system, you may be placed on a public hospital waitlist as part of the elective surgery process, with timing depending on clinical urgency.
Those with private health insurance may be able to access treatment sooner in a private hospital, though waiting periods and policy exclusions can apply. privatehealth.gov.au is a useful government resource for comparing what different policies actually cover before you commit.
Before any procedure, your surgeon’s rooms should provide informed financial consent, meaning a clear written estimate of expected costs and any likely gap payment. It’s worth asking questions at your pre-admission clinic appointment if anything is unclear.
Preventing Skin Cancer: Sun Safety Basics
Australia has one of the highest rates of skin cancer in the world, largely due to strong UV exposure.
Simple sun safety habits, such as wearing protective clothing, applying sunscreen, seeking shade, and getting regular skin checks, remain the best defence. Reliable, practical guidance is available through healthdirect and your local GP clinic.
For those wanting more detail on surgical standards and who performs these procedures, the Royal Australasian College of Surgeons sets training and accreditation standards for specialist surgeons across Australia.
Conclusion
Skin cancer removal surgery is a common, generally well-tolerated procedure, whether it’s a straightforward excision or a more precise Mohs technique. Understanding the difference between the two approaches can help you feel more prepared and ask better questions at your appointment.
Every situation is different, so the right approach for you depends on the type, size, and location of the lesion, which is best discussed with your GP, dermatologist, or specialist surgeon.

FAQs
1. How do I know if I need excision or Mohs surgery?
This depends on factors like the type of skin cancer, its size, and its location, particularly whether it’s on a cosmetically or functionally sensitive area like the face.
Your dermatologist or surgeon will recommend the most suitable option after examining the lesion and, often, a biopsy result.
2. Is skin cancer removal surgery painful?
Most procedures are done under local anaesthesia, so you shouldn’t feel pain during the surgery itself, though some pressure or tugging is common. Mild soreness afterwards is normal and can usually be managed with simple pain relief as advised by your treating team.
3. Will I need to stay in hospital overnight?
Most skin cancer removal surgery is done as day surgery, meaning you go home the same day. A hospital stay is more likely only for larger, more complex cases or where a general anaesthetic and closer monitoring are needed.
4. How much does skin cancer removal surgery cost in Australia?
Costs vary depending on whether you’re treated in the public or private system, the complexity of the procedure, and your specific Medicare and private health insurance circumstances.
For current rebate and cover information, check servicesaustralia.gov.au and privatehealth.gov.au, or ask your surgeon’s rooms for a written estimate.
5. Will I be left with a noticeable scar?
Some scarring is expected after any skin cancer removal surgery, though surgeons take care to minimise this where possible, especially on visible areas like the face.
Scar appearance generally improves over months, and your surgeon can advise on realistic expectations for your specific case.
