BREAST CANCER RESEARCH RIGHT NOW! #73: Lymphedema and Mosquitos and PROTECTION?!?!?


From the first moment my wife discovered she had breast cancer, there was a deafening silence from the men I know. Even ones whose wives, mothers or girlfriends had breast cancer seemed to have received a gag order from some Central Cancer Command and did little more than mumble about the experience. Not one to shut up for any known reason, I started this blog…

Every month, I’ll be highlighting breast cancer research that is going on RIGHT NOW! Harvested from different websites, journals and podcasts, I’ll translate them into understandable English and share them with you. Today: see below for links to several articles.

Honestly, there doesn’t seem to be much research into the effect of and prevention of lymphedema in people who have to deal with it on an everyday basis.

While there are a number of different aspect to living with lymphedema, during the summer in Minnesota, bug bites fairly leap to the forefront.

Given the ubiquitous nature of arthropods biting people who have lymphedema, you’d think there were be a push to find a way to REALLY deal with it in the long term.

But there’s not. According to what I could find, there are only two aspects of the whole bites-n-lymphedema issue: protect and prevent, treatment.

Protect and prevent is all about “shields” and are essentially of two kinds: chemical and physical. (Don’t waste your time with the “sonic bug repellers” – they don’t work (https://www.nachi.org/ultrasonic-pest-repellers.htm)).

First, the definition: “When an insect bites, it injects a toxin into the skin that causes the resulting itching. The reaction in lymphedema-affected tissues to insect bites can be potentially be severe. In response to the bite, there may be a temporary increase in the swelling of the affected limb. Also, it may take lymphedema-affected tissues longer than normal tissues to clear this substance from the body.

“If you have multiple bites on an affected limb, seek medical advice immediately!
Don’t scratch! A cool wet cloth or cold pack will ease the itching and swelling. If the itching is severe, seek medical help. As long as no infection present it should be safe to perform self-massage to help the body clear toxins from this area. When doing this, massage the area above the sting, i.e. closer to the trunk.”

This is the main reason behind taking protective measures for people who have to deal with  lymphedema – to prevent swelling. Another reason is to, of course, prevent the transmission of disease.

The chemical premise of protection from bug bites goes like this:

“The cornerstone of prevention efforts involves the use of effective insect repellents which can significantly reduce the likelihood of bites from mosquitoes and ticks...DEET (N, N-diethyl-meta-toluamide) is the most well studied, and most effective, broad-spectrum repellent against biting arthropods. The World Health Organization and the CDC recognize DEET as the gold standard insect repellent and is the agent against which other repellents are measured…Alternatives to DEET include picaridin (REPEL Lemon based…brand, as well as Wondercide and Sawyer – sold at various and sundry places) and PMD (P-menthane-3,8-diol)…a component of lemon eucalyptus extract that has been shown to have effectiveness and duration of action similar to DEET (Cutter Lemon Eucalyptus is one of many).”

The physical premise for protection lies with clothing:

“…light-colored pants, long-sleeved shirts, and hats also reduce the likelihood of sustaining insect bites…and the application of permethrin, a synthetic insecticide derived from the chrysanthemum plant, to clothing (never directly to the skin) ,greatly improves the deterrence of insect bites…Studies regarding the use of mosquito nets, especially those impregnated with permethrin, demonstrate they are highly effective in preventing bites and stings from a variety of arthropods.” (Sawyer brand of CLOTHING, GEAR, and TENT spray – only! ( https://sawyer.com/videos/permethrin-clothing-gear-insect-repellent/) Not on skin!)

Below you’ll find links to articles and insight into preventing bug bites and avoiding the increased pain and irritation of insect bites, which can only add to the misery of lymphedema.
