Will Miradry Increase my Risk of Cancer?

I am 31 years old and have had axillary hyperhidrosis since the age of 13. I have used CertainDri (which sometimes works, but causes intense burning and itching), and have contemplated Botox. However, I would like to try to conceive in the next year and would also prefer to find a long-term solution to my hyperhidrosis rather than a temporary bandaid. I'm concerned that since Miradry is so new, that we may not know the long-term effects.

MiraDry risks

There have been no evidence that miraDry produces cancer of any type.  The risks to the procedure are local, meaning that you can have some swelling that goes away in a few days to weeks, you can have some bruising, and in some cases you may need another treatment if you truly have hyperhidrosis.  miraDry seems to be both safe and effective, which is why it seems to be so popular!  In having it done myself, I love to be able to ride 50 miles on my bike without using antiperspirants or deodorants and still not smelling at all at the end of my ride.  It has been really amazing for me personally, and I recommend it to my patients without reservations!

Best wishes,

There have not been any side effects associated with miradry after 3 months.  I do not see a way it could even cause cancer

Miradry procedure is very safe. We have performed hundreds of these in our office. It affect sweat glands which are positioned right under the skin level. Breast tissue or lymphnodes are way deeper than that. What is nice about this procedure the satisfacton rate is close to 100%!

MiraDry safety

After the miraDry treatment at the BioSpa Newport Beach, your underarm sweat and odor glands will be eliminated. While your body does need sweat glands to cool itself, your body contains 2-4 million sweat glands – only about 2% are found in your underarms. Eliminating this 2% of sweat glands, does not affect your body’s ability to cool itself.

No Risk of Cancer with Miradry

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
The FDA has cleared MiraDry for permanent reduction of sweating in the underarm area.  There has never been a link to cancer.  It is not radiation treatment, but instead it uses microwave energy to kill the sweat and odor glands in the underarm.  When considering that some investigators have tried to link the aluminum compounds in antiperspirants with cancer and Alzheimer's disease, MiraDry is probably safer than the daily use of a topical antiperspirant.

Miradry addresses the sweat glands of the armpits and does not have any specific cancer risks. It is FDA approved and I have found it quite safe in my patients.

Although miraDry is getting a lot of attention recently, it has actually been around for a while. It has been extensively studied and there is no cancer association. The FDA has cleared it for safe use as well. The microwave energy only penetrates 4-5mm in depth and heats up and destroys the sweat and odor glands. The energy does not reach lymph nodes or deeper structures and it in non-ionizing radiation (the safe kind, like radiowaves). I have had the procedure done myself and it has truly been a gift. One and done for 80% of people! In the long term, much more cost-effective than Botox which has to be repeated every 3-6 months. Let us know if we can help in any way.

MiraDry does not increase risk of cancer

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
MiraDry is a safe and effective way of removing unwanted hair and sweat glands from your axillae (armpits). There have been no reports of cancers triggered by MiraDry. The energy used by MiraDry is the same as used in your average cell phone. You are likely to be exposed to less electromagnetic radiation with MiraDry than with a long telephone conversation while holding your phone by your ear. Isn't that something to think about?

MiraDry uses electromagnetic energy, ie. microwave technology to heat up and destroy your apocrine and eccrine sweat glands. This is NOT radiation injury. To date miraDry has been deemed safe by the FDA, US, CE, Europe, and most recently the TGA in Australia for the treatment of excessive underarm sweating. 

Hope this places your mind at rest.

MiraDry is safe and effective

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Hi there-

The great many patients who have been treated with miraDry over the multiple years of research now have not ever experienced a link of any kind to cancer. The microwave energy used in the procedure is very tightly focused at the depth of the sweat glands, and this limited penetration is a major reason for its high degree of safety.

It is also worth pointing out that among all procedures on this site, miraDry has been among the 2 or 3 with the very highest rates of patient satisfaction.
