There simply has not been enough time,using this radical procedure,for anyone to know for certain,if it is efficacious or just some new worthless experiment.
That's OK, I know what you mean. I have to laugh about it, what else can you do? There must be some sort of cancer preventative gene that is lacking on my dad's side of the family. It's not just one kind of cancer, like this particular type of breast cancer in the article that follows the maternal line, it's all over the board. There's a lot of intermarriage in his ancestry, seeing as how they're from an isolated fishing village that was only accessible by boat until they built a highway through that area in the 1920's. My grandparents were second-cousins. There's a high proportion of blue eyes and left-handedness in the area, too (and curiously enough, a very high proportion of school teachers--my dad was one). I'm sure there's a genetic predisposition for cancer, and my dad's people have it in spades.
Apparently you don't understand that more time has rto pass,before these studies mean anything.But then,you also believe the junk studies about smoking too,which are not valid either.:-)
Well, there you go, 'body image and sexuality' are more important than increasing your life expectancy.
If you have problems with the studies, please be specific.
LOL! I made sure to marry waaaaay away from my gene pool...out of the state, and out of the country, to be exact. Well, I married in the state, but his genes come from out of the country.
The studies started in 1960. How long do YOU want to wait?
At least you don't call them JUNK studies.
Or maybe we could let them make the choice for themselves. There's a thought!
I know of a young woman, early 20's that had breast cancer. She had to have masectomies, lost her hair from the chemo. I suspect that if she had been told earlier that she had a 90% chance of developing breast cancer, she just might have opted for early removal.
One doesn't have to be elderly to get it and one doesn't have to be female either. One of my cousins, a male, had breast cancer.
Another cousin of mine (female) has Lupus. She and her boyfriend at the time (husband now) had discussed the issue. He has some genetic disease as well, though I don't recall what it is. They agreed that it was best to not have children and risk passing it on. (sorry I can't recall what his disease is.)
Survival from all breast cancers is 88% when diagnosed early regardless of genetics. BRCA-associated cancer is no more aggressive than non-BRCA cancer.
Please post a link/source.
And the studies were on a very tiny segment,so the length of time is beyond the point.Nowa,that apparently more and more women are falling for this garbage,let's wait and see.
I'm not a plastic surgeon but I am a physician. I keep current with most medical topics.
A piece of crock?????

Gold "nano-bullets" shoot down tumours

Gold "nano-bullets" could seek and destroy inoperable human cancers, suggest new studies by US scientists.
The tiny silica particles are plated with gold and heat up when near infrared light (NIR) is shone on them. This kills the cancer cells. Tests on human breast cancers, both in the test tube and in tumours in mice, were highly successful, the researchers report in the Proceedings of the National Academy of Sciences.
"The nanoshells are designed to absorb near infrared light and convert that light to heat," explains Jennifer West, who led the study at Rice University, Houston, Texas. This is possible because the body's normal tissues are "essentially transparent" to NIR.
West says the potential benefits of the treatment should be that, unlike other cancer treatments such as surgery, it would be non-invasive. Both NIR and the nanoshells are completely harmless by themselves, she says.
"We believe that we should also be able to treat very small metastases, not detected yet," West told New Scientist. More recent, unpublished work by the group, has shown that the gold bullets can be injected into the blood stream and find their way to cancer cells in mice.
"These results are promising, particularly for tumours that cannot be treated by surgery," says Emma Knight, at Cancer Research UK. "However, the studies are at a very early stage."
On/off switch
The Rice University team created nanoparticles from a non-conducting core of silica with a diameter of 110 nanometres and a 10 nm thick metal shell. Gold was used because it is biologically inert.
When the nanoshells were added to human breast cancer cells in the test tube, and then exposed to both NIR, 100 per cent were killed, says West. "And we saw no changes in cell viability with just nanoshells or just the laser - it's a true on/off situation."
The team also injected the nanoshells directly into the tumours of living mice and applied NIR. The tumours were destroyed within days.
Warming the tumour cells to only about 55°C is enough to kill them, because it changes the permeability of the cell membrane. "Leakiness is what causes the cell to die," West explains. "Cells normally have to have a very tightly controlled barrier between the inside of the cells and the fluid surrounding them. If you disrupt that, you create huge pores which lets everything across, significantly changing the composition of the fluid inside - it ends up very toxic."
Right on target
The team has now engineered the nanoshells to specifically target tumour cells. In a recent study, submitted to Cancer Letters, they injected mice with nanoshells attached to an antibody that only binds to cancer cells. She says the tumours were "completely destroyed" and 150 days later the mice were alive and well with no tumour growth.

This unpublished study was done in collaboration with Nanospectra Biosciences in Houston, which is now in talks with the US Food and Drugs Administration about moving to human clinical trials within the next 12 to 18 months. These trials are planned in patients with a severe, highly lethal form of lung cancer called mesothilioma.
West says that in the longer term, they hope the nanoshells could even be used as a precautionary measure, killing cancers while they are too small to be detected. "For example, if you had genes predisposing you to breast cancer, you could have this done on a periodic basis," she says.
Nanoshells have not been used to treat cancer before, but the concept of targeting tumour cells and then delivering a killer blow not unique. For example, a team at Nottingham University in the UK is developing a way of delivering a "prodrug" using tumour-loving bacteria. When the drug is activated by an injected molecule, only the tumour cells are killed.

Give me a while. I'll work on it.
But once an idea strikes your fancy,you stick with it,posting just your side,no matter what others say/post to the contrary.LOL
I don't know....
But whatever I would decide, it's none of your business.
But then again, I'm sure you'd be here to inform me my decision was wrong, and to question the motives of the Doctors involved because they got paid to do the surgery (oh...and don't forget thte Anesthesiologist too).
There's an old saying in the military...
"Never underestimate the courage of the non-combatants".
You say she made the wrong decision...but then again, you and I are not in her situation. I do not know what I would do...but I do know enough to know that I (and you) are in no position to criticize her or her physicians.
It's off topic, but here's a medical history trivia question for you. My mom was a nurse, and back in the 50's she worked with this doctor who was quite old, who told her that he (or a doctor he had worked with in the past, she can't remember which) was in some hospital and he visited the public ward, and wasn't there very long before he said, "Why do you have a typhoid case on the public ward?" (as opposed to the isolation ward) And whoever was in charge of the floor asked, "What the hell are you talking about? We don't have any typhoid here." And he said, "Somebody here has typhoid." So, how did he know?
