Understanding the risks, benefits and safety of minor surgical procedures

This is Article 5 of 8 in our guide to skin lumps, bumps and minor surgical procedures.

In our previous article, What Happens During Lump and Bump Removal?, we discussed what patients can expect on the day of their procedure.
The next question is often:

“What could go wrong?”

It is an important question.

At Compass Surgical, we believe patients should understand both the benefits and the potential risks of any procedure before making a decision. Patients who would like additional information about surgical risks and informed consent may also find the Royal Australasian College of Surgeons (RACS) patient information resources helpful.

The good news is that most lump and bump procedures are straightforward, performed under local anaesthetic, and associated with a very low risk of serious complications.

However, no surgical procedure is entirely risk-free.

Understanding those risks helps patients make informed decisions and approach treatment with realistic expectations.

Is Lump Removal Safe?

For most patients, yes.

Minor surgical procedures such as the removal of cysts, lipomas, skin lesions and other soft tissue lumps are performed safely every day.

Most patients experience uncomplicated healing and return quickly to normal activities.

The risks are generally small, particularly when the lump is benign, well-defined and located in an area that is straightforward to treat.

Will I Have a Scar?

This is often the most important question for patients.

The simple answer is yes.

Any procedure that involves cutting the skin will leave a scar.

Our goal is always to place incisions carefully and achieve the best possible cosmetic result, but no surgeon can remove a lump without leaving some degree of scarring.

Fortunately, most scars soften and fade significantly over time.

Factors that influence scar appearance include:

  • The size of the lump
  • Its location
  • Skin type
  • Individual healing characteristics
  • How well the wound heals

We’ll discuss scar care and wound management in more detail in the next article.

What Are the Most Common Risks?

The most common complications are usually minor and temporary.

These include:

  • Bruising
  • Swelling
  • Tenderness
  • Minor wound bleeding
  • Temporary numbness around the wound

These symptoms are a normal part of healing and usually improve steadily over days or weeks.

Can the Wound Become Infected?

Yes, although infection is uncommon.

Signs of infection may include:

  • Increasing redness
  • Increasing pain
  • Swelling
  • Pus or wound discharge
  • Fever

Most infections respond well to simple treatment if identified early.

Patients are given instructions on what to look out for and how to seek advice if concerns arise.

Can the Lump Come Back?

Sometimes.

The risk depends on the type of lump being removed.

For example:

  • Some cysts can recur if part of the cyst wall remains behind.
  • Certain skin lesions may reappear over time.
  • Some soft tissue lumps have a small risk of recurrence even after complete removal.

Where recurrence is a recognised possibility, this is discussed before surgery.

What About Nerve Damage?

Small nerves run throughout the skin and underlying tissues.

Occasionally, removal of a lump can result in:

  • Temporary numbness
  • Altered sensation
  • Tingling around the scar

In most cases, these symptoms improve with time.

Permanent changes in sensation are uncommon but can occur, particularly when lumps are located close to important nerves.

What If the Pathology Result Is Unexpected?

Most pathology reports confirm the diagnosis that was suspected before surgery.

Occasionally, however, the laboratory identifies something unexpected.

This is one of the reasons most removed tissue is routinely sent for histological examination.

If further treatment or follow-up is required, your surgeon will discuss the results and the next steps with you.

What Are the Risks of Not Removing a Lump?

This depends on the diagnosis.

Many benign lumps can safely be observed.

However, leaving a lump untreated may sometimes result in:

  • Continued growth
  • Increasing discomfort
  • Recurrent infection
  • Cosmetic concerns
  • Delayed diagnosis if the nature of the lump is uncertain

The decision to proceed with surgery should always balance the potential benefits against the risks of treatment.

The Compass Surgical Approach

Compass Surgical was founded on a simple principle:

Do the right operation, for the right patient, at the right time.

Our practice is built around:

  • Patient-centred care
  • Surgical integrity
  • Evidence-based decision-making
  • Clear communication
  • Personalised treatment plans

We believe discussing risks openly is an essential part of good surgical care.

Our goal is not simply to remove a lump.

Our goal is to ensure patients understand the risks, benefits and alternatives so they can make informed decisions with confidence.

What Next?

Fortunately, most patients recover quickly after lump removal.

Understanding how to care for the wound, when to return to exercise and how to achieve the best possible scar can make recovery smoother and less stressful.

In the next article, “Recovery After Lump Removal”, we’ll discuss wound care, showering, swimming, exercise, scar management and what to expect during the healing process.
