Malignant is the word.
malignant;
Harmful, malevolent, injurious.
(oncology) Harmfully cancerous.
And the other type of tumor is benign.
benign;
Kind; gentle; mild.
(medicine) Not posing any serious threat to health; not particularly aggressive or recurrent. (+ info)
Last month I saw a black spot on my gums which disappeared in 2weeks however the skin texture is little rough.?
Would like to know if it can be malign. I have a dentist appointment next week and the doctor suggested a biopsy just to be safe...what can I expect in a biopsy?
----------
A black spot on the skin anywhere can be an indication of a malignancy and it's good your getting yours checked.
Let's hope that's not the case with you.
The doctor/dentist might just take a scraping or possibly dig a little deeper for a small sample for the biopsy but it shouldn't be very painful. And that's not the important thing here...hearing the doctor tell you the tests were "negative" will make any discomfort you might experience well worth it.

Can the brain be damaged by following behind a diesel truck or construction vehicle in a car?
Pretty straightforward question. Diesel exhaust emits a crapload of harsh chemicals and particulates - the nanoparticulates are capable of channeling up through the olfactory nerve and embedding themselves in the brain, and many of the other chemicals therein the exhaust itself are bioaccumulative, meaning they get in your body and stay there...for decades.
I have a 2007 Ford Ranger. I always set my air conditioning to MAX A/C (recirculate) when on express ways and such, but I realize even that isn't going to defend me from the tiny particulates that do all the damage.
Earlier today, I got stuck behind a construction vehicle that was jetting off thick, dense plumes of exhaust into the air. I was behind it for approximately a quarter of mile, with nowhere whatsoever to go to seek safety or respite. I wasn't, however, actually able to smell the exhaust at all, but that isn't a denotation that the particulates weren't still pregnating the cabin and contesting the interior air of my vehicle...
Irregardless, question in point, can experiences like these sufficiently expose a healthy person to enough particulates or toxins to cause any harm to the lungs, or deposit the nanoparticles in the lung tissue itself? In addition, is it possible for the brain to be damaged from such short exposures like this, at all? Any brain cells whatsoever? And if so, would it be anywhere as significant an amount as having a bottle of beer, or is it a menial and totally negligible amount with absolutely no bearing on cognitive development and performance?
As far as my personal experience goes, I do have a headache, but I'm hesitant to correlate it, simply 'cause I've had the headache all day long from sinuses. My motor functions check out fine, my ABCs can be recited flawlessly, balance is in check, etc - neurologically, at least, no malign issues appear to be evident.
So what're some scientific, more knowledgeable opinions?
Diesel is horrible, dangerous stuff, and even very short exposures have been shown to generate oxidative stress in the brain. The exact mechanism for this has not yet been identified, but current speculation is it's because of the nanoparticulates channeling up through the olfactory nerve and embedding in brain tissue.
http://www.sciencedaily.com/releases/2008/03/080311075339.htm
And to the ignorant people who would claim that particulates cannot travel directly from the nose to the brain, be enlightened with this:
"In animals, it is known that particles from vehicle fumes can travel along the olfactory nerve, from the nose to the brain. Once there, the particles can damage cells and cause inflammation of brain tissue. Studies of dogs from heavily polluted areas of Mexico City, for example, showed that their brains had damage similar to that seen in patients with Alzheimer's disease."

I get new scientist lists too. Did you see the one on galactic wars in other parts of the universe?
Regarding "safe levels of exposure", I don't believe there is a safe level at all. Most drugs and pollutants go up to the FDA, but do you really see anyone legislating against the oil companies?
Maybe 50 years in the future we will look back in wonder the same way we do now regarding asbestos.
All I suggest in these situations is either try and overtake, or hang well back - letting others overtake you.
Effects are more likely on your lungs to cause localised cancers over time.
I hope it doesn't get so bad as to need a smog mask - but they are available - http://www.discountbicycles.co.uk/biz/section.php?xSec=4098
If you are concerned over brain damage - Research the effects of MSG - found in most foods mis-labelled as "natural flavourings, Naturally flavoured', or as part of the make up of supplied ingredients, like golden coating. However, there is no limit on this - and the FDA are quite happy with it. (+ info)
how much can polyps be hazardous if stay in intestinal tract for several years.?
50 years old woman doesn't wanna go to doctor for surgery,how long she can live with these polyps without getting sick.they were not malign ones but can they be change to bad ones in a long run.
----------
The only way to tell if the polyps have become malignant is through the colonoscopy. Well, you can tell if the polyps have become cancerous and you get really sick, but then it's too late. The woman needs to go to the doctor and have the colonoscopy. They probably can remove the polyps at the same time. It's embarrassing and uncomfortable. It's also almost out patient surgery and she'll live a longer more comfortable life afterward, and so will the people who love her. (+ info)
Do you need to be clever to lose weight?
In an official press release in US said...
"Anyone wishing to achieve a hot "beach bod" is reminded that studies show that
vegetarians are on average, about 10 to 20 pounds lighter than meat-eaters."
That may be true to some degree, I doubt anyone will listen.
This fact will probably anger people and defy more than anything else.
The much maligned by non violence activation group's new message is, "Save the Whales" by giving up meat if you need to lose weight.
It's clever, but is it effective?
----------
Despite the way it feels, losing weight isn't a mysterious process. It's a simple matter of burning more calories than you eat.
But, if it were really that simple, none of us would have a weight problem, would we?
Weight loss can be such a struggle that we start thinking we have to do something drastic to see results -- diets, pills or those weird fitness gadgets on infomercials that promise instant success.
The true secret to weight loss is this: Make small changes each and every day and you'll slowly (but surely) lose those extra pounds. The key is to forget about instant results and settle in for the long run. (+ info)
Has anyone had a thyroid gland removed ?
The specialist tells me there is only a 5% chance the lump is malign but advises me to have it removed just in case and to do it in the next 6 weeks . He says the body can function with just one thyroid . Has anyone had the operation or know what the after effects might be ?
----------
While I have not had surgery to have my thyroid removed, I had my thyroid removed via radiation treatment (and now take synthroid daily - 125 micrograms). Also, as a Physician Assistant student I scrubbed into a couple of thyroidectomies (surgical removal of the thyroid gland.) It is a rather delicate surgery, as the area is very close to major blood supply lines that are in the throat. And the thyroid lies very close to a very important nerve called the recurrent laryngeal nerve. This nerve controls speaking, without it your voice is very hoarse sounding all the time. That being said, the risk of injuring the nerve is always minimalized during the surgery. The first thing that is done is identifying that nerve so no harm is done to it. Another problem with the surgery is that your parathyroid glands lie right on top of your thyroid. Your parathyroid glands control the calcium in your body, removal of them means you will have low calcium uptake in your body. Now it seems you will only have one lobe of your thyroid (or half of your thyroid) removed, so you may not experience this because you will still have both parathyroid glands (there are naturally 4 parathyroid glands) remaining on your other lobe. They will still probably test and make sure you are not hypoclacemic (have low calcium in your body) after surgery. Your doctor will also talk to you about the risks and benefits of surgery. Also, read up on thyroid nodules. Most, as your doctor said, are benign, but the ones that are malignant can be very deadly very quickly.
After surgery, your doctor (probably not your surgeon, but your endocrinologist or family doc) will monitor your TSH levels via blood levels. They will make sure it stays within a theraputic range (meaning your body is getting enough TSH in the body). If your body is not getting enough TSH you will be put on replacement medications (like synthroid, what I take) that will get your body the TSH it needs to survive. It may take a while for your levels to reach theraputic range, but don't get discouraged. It took me about 9 months to get regulated and it was awful timing. I was very grateful when I was regulated. And now its been about 12 years, and I feel great. Good luck! (+ info)
Are American beers unfairly maligned?
Are German beers overrated?
I know the big U.S. breweries get a lot af sh*t for being weak, but the fact is that the alcohol content is around 5-6% which is about the same as foreign beer and the quality is consistent. Perhaps the U.S. preference for the lighter taste and texture may simply be because of the U.S.'s generally hotter climate.
I personally think American microbreweries put out the best variety and quality of beer anywhere on the planet (Sam Adams, Sierra Nevada, Sweetwater, Terrapin, Red Hook, etc). Does Germany have the variety of beer that America has, or is it pretty much light German lager everywhere you go?
Here's some articles from a few years ago on the subject/.
http://www.xs4all.nl/~patto1ro/gersbeer.htm
http://www.xs4all.nl/~patto1ro/wbger.htm
My not so guilty secret is that I actually like Budweiser. I tend to drink it during the summer, though, when it is too hot to drink a more full flavored beer like a Sam Adams. I think that is one reason for the predominance of lighter lagers. If Europeans experienced summers like we do here in the States, I have a feeling their tastes would change too.
Of the big U.S. breweries, I personally think Bud is the only one with any taste. I've heard rumors that Bud brewers are actually tinkering with the recipe and addng a little more malt and hops.
I agree that Miller is crap (although I find Miller Lite is actually drinkable) and Coors has to be one of the most tasteless beers ever made. I'd sooner drink a Pabst Blue Ribbon.
I exagerate about the Coors family, but not by much. They are tied to a number of right wing, anti labor organizations.

----------
That bias is based on the macro brews like Miller, or Budweiser. Our micro brews like the ones you mentioned are easily in competition with theirs. It's unfortunate that as a populace Americans like crappy beer though. This can be shown simply by looking at sales. (+ info)
Is a 40 yo too old to have leg straightening done?
This involves breaking the bone and is to avoid future problems stemming from a maligned childhood fracture. Is it better to just live with the consequences or take the risk of a lengthy healing period with all the employment issues?
----------
Yikes, what kinds of problems is it giving you now and to what degree is the pain disrupting your life now? What are the risks of surgery and how long would you be out of commission? These are questions you have to ask yourself. I have heard of people that have corrected their own bodies by doing yoga.
I am afraid of my arm ending up in the same situation. None of the docs will listen to me when I say it is dislocated, plus it is fractured in several places and they just splinted it- still dislocated so I having pain problems in the cast, plus my wrist hurts because of the dislocation of the radial bone on the proximal and distal end.

What do you think of this claim that The president of this African country cured at least 30 people of AIDS?
The President of the Gambia, Yahya Jammeh, is claiming to have cured people of the HIV virus, using African traditional medicines. The cure is limited to practising Muslims, and the cure is effected as follows:
The patient is asked to sit up from a recumbent position. If he is unable to do so, then it is a sign it is too late. If he is able to
do so, then the next stage can begin. The patient lies back again, while the president of the country
takes out some African herbs, whispers a few prayers, then rubs the herbs into his hands, hovers his hands over the body of the patient (not actually touching the person) then when the hands move from the head down over the stomach, the president grabs the air and acts as if he is grabbing the malign presence of HIV and "pulling it out of the body", and repeats this motion a few times. When this procedure is completed, the patient has to say his prayers as dictated by the Quran. Candidates have to have the HIV virus before being cured.
To allay accusations of quackery, stringent blood tests are made in a lab in the neighbouring country, Senegal, in Dakar. Before, the blood shows evidence of the HIV virus, but afterwards, allegedly, there is no evidence of the virus. Stringent testing. The president claims that the virus was created by the white man in order to kill africans. He dismisses people who do not believe this as "unbelievers" and says that Western medicine is not the only medicine that works.
So what is your take on this? I wonder if this has been made available in the media in the Western world? As a european, I had to keep my opinions to myself as my colleagues firmly believe this. I told them only one thing... that it was dangerous and irresponsible what he was doing.
----------
If you're just asking for an opinion, then I would have to answer that I think it's possible. I haven't heard anything about this on the news, but that contributes to the possiblity that maybe a cure DOES exist but as pointed out earlier, western medicine RELIES on sick people to stay in business and curing illness does not create a, how shall we say, "repeat customer". My personal experiences with Native American medicine (my father and his side of the family are Navajo) has led me to believe that almost anything is possible.
Believe it or not, but the mind has much control over what the body does, including the body's own ability to naturally heal. Western Medicine is founded on the belief that only large amounts of drugs, medical care, and therefore CASH can cure you.
Suddenly there is a pill for every possible ailment, and even some ailments that are purely made up! Studies have shown that Viagra and such related products work almost solely on belief that the pill works. Slipping a guy a viagra when he is unaware is not going to turn him into a raging stud, he has to know that he has taken the pill. I'm not saying that people can simply cure themselves from AIDS by believing they can, but I refuse to think that it is uncurable.
As far as Yahya Jammeh claiming that AIDS is a weapon of the "white man", this might just be propaganda, especially as he holds the title of the president...
Long story short, I'm open minded to the idea, however I will continue to examine every opinion, story and so called "facts" sent my way. I'd like to know if these labs that are examing the blood for traces of AIDS are in any way affilliated with Jammeh and would support him in any kind of conspiracy... After all, any guy who could cure terminal inllnesses would have my vote. (+ info)
What are tumors made of ? & what makes them grow??
my niece had a tumor a year ago..and it was taken off it was by her brain....but recently she got an MRI.. and they said they saw sumting unusual.... that it might be growing back...but they said it wasnt cancer or malign ( i donnu how to spell it)....im confuzed...... help
----------
Benign tumors are made of the same tissue that surrounds them. For example, myomas are made of the same muscle of the womb, but their distribution seems a whirlpool and not smooth and contractile muscle.
Malign tumors are made of anarchic and disorganized tissue (and may even be different from the tissue that surrounds them). This is the clearest in teratomas of ovary or testes, made of hair, teeth, etc. (This is due because eggs and sperm are capable of generating any tissue for the possible new being) (+ info)
