French Doctors to Perform Zero-Gravity Surgery
STFS writes "NewScientistSpace has a story about a team of French doctors who will attempt the worlds first zero-gravity operation on a human aboard an Airbus A300 dubbed "Zero-G". The patient, according to forbes.com, was chosen because of his experience with 'dramatic gravitational shifts' as an avid bungee-jumper. The operation will serve as a test for performing surgery in space."
From the TFA: "The European space plane, a specially-adapted Airbus A300 operated out of Bordeaux, flies in a series of roller-coaster like parabolas, creating between 20 and 22 seconds of weightlessness at the top of the curve, a process repeated around 30 times for a 3-hour flight.
As well as the challenge of working in zero gravity, the surgical team will have to halt their work each time the plane pulls out and gravity resumes."
22 seconds multiplied by 30 is 660 seconds, that is only 11 minutes of surgery for 3 hours. I wonder if that tumor could be removed during this 3 hour session.

Since this is /. after all, reading the linked artcile is strictly optional, of course
From the article
1) It is ESA and not NASA
2) They are doing the operation in 20 second increments
3) There will be 30 such spots when the actual operation is done
4) Whole flight will be 3 hours
"Martin's team laid the groundwork for Wednesday's operation in October 2003, with an operation on a 0.5 millimetre-wide (.01 inch) rat tail's artery."
You don't think enough... therefore you better not be!

Sounds like removal of a "lipoma". (I've had a few of those removed.)
Think of it as "cancer of the fat" - except benign. You get stiff fatty lumps (maybe one, maybe a scattering, maybe like a bunch of grapes). They're like regular fat with some kind of other tissue in them that makes them hard.
It's really annoying if it's above a muscle or some other easily hurt tissue: It's like a rock embedded in the fat that is SUPPOSED to be cushioning the tissue, so lying on it bruises the tissue instead.
They never go malignant so doctors will leave them in unless they're bruising something underneath or causing a disfiguring bump. They're near the surface of the skin so they're easy to cut out - usually by a dermatologist.
Sounds like the perfect test operation. Not a big deal if they don't get it all, near the surface so you don't have to cut through vital stuff or clamp stuff out of the way to get to it, etc. Easy to tell how well the op went. Much less opportunity for screwups than just about any other surgery.

With a continuously occupied space facility, private ventures planning to establish "space hotels", and with plans (mentioned in TFA) to establish a permanently inhabited moon base in the next few decades, possibly followed by manned missions to Mars which will take a very long time in transit, yes, there is a reasonably predictable, not too distant future need to have techniques available to perform surgeries in low and zero gravity.
Conducting a fairly low risk surgery under conditions where return to gravity and to earthbound facilities in reasonable time are not impractical seems to me a reasonable way to approach the development of such techniques. Of course, there is always a risk associated with such experimentation. which is why you have informed consent of a volunteer subject.
I know this was a sarcastic post most likely, but while you are free falling, you are physically experiencing zero gravity.
No. When you are free-falling, you are experiencing acceleration due to gravity of 9.81(ish*) m/s^2. What isn't experienced is the upwards force keeping you stationary on the ground. There's a (massive) difference.
A lipoma is benign, however they can undergo malignant transformation - just like any tissue in the body. Generally the small (5 cm and deep to the fascia ( a gristly layer over the muscle) tend to malignantly transform and should be excised.
,the bad ones tend to be firmer and look funny on MRI.
Dermatologist generally don't do cancer operations - they take out skin lesions a bit at a time untill they hit healthy tissue. If something is deep to the skin - i.e. a lipoma, it should be removed by a surgeon (general, or orthopaedic) that specialises in oncology. The only real way to determine if they are benign is to examine it pathologically. Generally the benign ones tend to be soft,
