Can Ultrasonic Cavitation Cause Cancer | Ultrasonic Cavitation Risks & Side Effects

Many myths and misconceptions revolve around ultrasonic cavitation machines. People say they can cause a variety of issues or dangers, including cancers that aren’t scientifically proven.

The reality of the matter is that these slimming machines are effective and safe when used correctly. Based on the study of Daniele Bani et al [1], noninvasive ultrasound cavitation treatment is a promising and effective technology for localized fat reduction. Since they work without invasive procedures, however, cavitation machines may have some risks.

Despite being relatively safe, some people are worried about the effects and risks. However, can ultrasonic cavitation cause cancer? We are going to shed more information regarding this concern for many people.

Is Ultrasonic Cavitation the Same As Radiofrequency?

Both methods are noninvasive, which can confuse many people. Despite the similar purpose, they have different modes of operation, giving varying results and side effects.

Ultrasonic cavitation

It is a method that uses low-frequency sound waves to break fat cells underneath the skin. The combination of heat and waves helps break and liquefy fat cells, allowing easy removal through the body system safely.

Radiofrequency technology

Radiofrequency ablation is a technology that heats collagen fiber which enables contraction. With tighter layers, the skin gains a smooth and firmer feeling.

Does Ultrasonic Cavitation Really Work?


Ultrasonic cavitation machines do work and deliver measurable results. However, the results aren’t instantaneous. You need to know that the process is for small areas and can be combined with other techniques for accelerated outcomes.  

Like other noninvasive techniques, ultrasonic cavitation requires patience and consistency to see results. Also, many factors will determine the efficiency. Some of these determinants are age, body type, frequency, and others.

The results also vary and won’t last the same for everyone. Although the slimming method might be working for you, it doesn’t mean it will be effective for others. Besides, there are several scientific trials conducted by professionals to analyze the safety and effectiveness of ultrasound cavitation treatment.

Through a study including 60 participants with a BMI over 30 kg/m2, Mohamed Taher Mahmoud ELdesoky et al found that ultrasound cavitation treatment, the same as cryolipolysis, was proved to be an effective and safe way to reduce abdominal fat thickness and achieve abdominal contouring [2].

In another review about noninvasive fat reduction in 2015, Kennedy J. et al discovered that high-density focused ultrasound (HIFU) was one of the four main non-invasive techniques to help people sculpt the body. The review included 31 studies in total, with 843 patients treated with HIFU for fat reduction or body slimming. Most of them turned out to be satisfied with the improvements. No serious adverse reactions were recorded during the process. The circumference of local fat tissue was decreased by 2 centimeters or more across the hips, abdomen, and thighs [3].

Moreover, there is one study made by Hong et al. concluding that a significant fat reduction of 3.43 cm in mean waist circumference was found in people subject to HIFU therapy [4].

Is Cancer One of Ultrasonic Cavitation Side Effects?

With ever-rising cases of different types of cancers, many questions surround the use of ultrasonic cavitation machines. Especially with France banning these machines in 2011 (although the ban was later lifted the same year), people were worried about the severe side effects. Can ultrasonic cavitation cause cancer?

From the health expert’s point of view and research, it is evident that ultrasonic cavitation doesn’t cause cancer. The technology uses low-frequency ultrasonic waves that are safe and don’t destroy body cells.

In simple terms, ultrasonic waves used in these devices are safe and non-ionizing. Although the technology is relatively new, there are no cancer cases reported from using these slimming machines.

The only precaution before engaging in this slimming mechanism is to consult your medical expert. This is because some cancers don’t go well with cavitation weight loss processes.

If Not Cancer, What Are Some Ultrasonic Cavitation Risks & Side Effects?

Despite ultrasound cavitation being great with minimal effects, you can still get side effects. Some most common include skin sensitivity, skin irregularities, headaches, bruising or redness, increased thirst, diarrhea, etc. Here are the details:

Skin Sensitivity

Skin sensitivity might occur due to the gel that experts apply before treatment. Also, the ultrasound technique of penetrating the skin layer can cause sensitivity. Itching or swelling may occur, but this is only temporary and will disappear after a few days.

Skin Irregularities

In some circumstances, the uneven fat breakage results in lumps and pimples on the skin. The body takes time to break down the ejected fat cells. Therefore, follow-up treatments can help with any bulges that remain.


Headaches and dizziness are prevalent and frequent. These symptoms are the result of toxins secreted in the body. After cavitation treatment, staying hydrated and exercising can help flush the system out faster.

Bruising or Redness

Bruising or redness of the skin may appear within the first few hours of the lipo cavitation machine treatment. It varies from patient to patient whether they acquire deep purple bruises or light red spots. The good news is it usually lessens and disappears after a few days.

Increased Thirst

Following the ultrasonic cavitation machine procedure, patients may report an increase in thirst. This is due to contaminants naturally coming out of your body. So, it’s a good idea to drink more water following treatment to speed up the flushing process.

Best Things to Do Before & After Lipo Cavitation Treatment

You should be reasonably active and consume a balanced diet before having ultrasound cavitation machine treatment. Most doctors would advise patients to drink eight glasses of water per day. Also, avoid alcohol and tanning in the week leading up to your first treatment session.

It’s critical to follow these guidelines as missing any can cause serious issues. To help your body process the excess fat and triglycerides, drink plenty of water after the treatment.

It would help if you avoided alcohol since it impairs the liver’s ability to metabolize waste substances. On the other hand, tanning your skin before treatment can make it highly susceptible to ultrasonic waves. Last but not least, exercise regularly after therapy. This will help your body digest the excess triglycerides and fatty substances that will soon say bye to you.

The treatment’s efficacy varies from person to person. It usually depends on their physical state. If you wish to know who’s the perfect cavitation massage candidate, here are the pointers:

  1. The person isn’t a smoker
  2. They have a solid overall health
  3. The individual is only 15 pounds away from their weight-loss target
  4. They have realistic expectations
  5. She is not expecting a child
  6. They lack any metal implants in the body

Does Ultrasonic Cavitation Offer Any Benefit?

Pain-free process

During the process, there is no surgery like when during liposuction. It involves the use of ultrasonic waves to liquefy the fat cells meaning there is minimal pain.

Through the power of sound waves, the fat is eliminated through the lymphatic system. Therefore, it is ideal for most people as there is no downtime.

Reduction of cellulite

Uneven skin due to underneath fat in the skin is a concern to many people. Ultrasound cavitation is one of the effective methods to achieve smooth skin.

By breaking the fat cells, the technology leaves skin looking uniform without the cellulite dimpling.

Easy body contouring

While exercises are great for keeping the body in shape, adding ultrasonic cavitation helps refine the contours. Especially when dealing with some parts, the technique is super effective for body contouring.

Whether it’s along the belly, butts, belly, or other areas, it’s possible to achieve the desired shape.

High versatility

The versatility is among the top benefits you get when using ultrasonic cavitation. Besides being useful for the reduction of body fat, the process is versatile.

One of the things that make the process versatile is its application to different body parts. Whether it’s around the belly, cheeks, or other delicate areas, the process is safe.

Besides, the application on different skins means most users can use it safely. Since lipo cavitation doesn’t kill or damage surrounding cells, it’s a great way to reduce fat and firm skin all over the body.


Ultrasound cavitation is a safe process that delivers visible results. It’s one of the safest noninvasive weight reduction techniques which provides excellent results.

Although many people have fears of getting cancer, the process is proven to be safe. Cancer isn’t one of the side effects or dangers that arise from using this technology.

While the lipo cavitation process is safe, it still has some side effects that might concern some users. Additionally, for people with some cancers, it’s not recommended to use ultrasonic cavitation.

The bottom line is ultrasonic cavitation cant doesn’t cause cancer.
