The prosecutors in the Martha Stewart Case used testimony from an FBI agent who lied under oath to secure a conviction. The prosecutors knowingly and willfully allowed the FBI agent to tell a lie while he was a witness in the courtroom. This is fascinating indeed as they could not convict Martha Stewart for insider trading, so instead tried to get her on a lying technicality to the investigators. So in essence the government lied to convict a Billionaire Tax Paying employer who built her business on blood sweat and tears from scratch on a charge of lying. How can we as Americans actually eve
So, as you can see, you want to find out what the survival rate is for patients with the same stage of disease.
What is remission?
Remission refers to a shrinking of a cancer. Remissions can either be complete or partial depending on whether or not any evidence of cancer remains. Obviously, if no cancer can be found after treatment then the remission is complete.
If the cancer is smaller but hasn’t disappeared completely then the patient has experienced a
Is your family ready for the big one? If not you should be and do not for a second believe that Earthquakes only happen in California. There are seismic faults all over the world and in some places you might not even think of. You might be surprised how close you live to one and realize with a big Earthquake damage can occur up to a 100 miles away and that’s only from the shaking, not even thinking of Tsunami wave action. One thing you must remember is simply because there has been a large quake does not mean there will not be many aftershocks which follow. The bigger the quake the larger th
Here is a guide to understanding some of the statistical terms you will run into when discussing cancer treatment.
Firstly, you need to know that no one can predict with total certainty any patient’s exact outcome. Instead, cancer mortality rates are based on the outcomes of large numbers of people who have had the same disease. In other words, the statistics that will be quoted to you are only probabilities.
A second thing to know is that not all cancers have the same outcomes. In other words -- some cancers are deadlier than others.
And the third thing to realize is that the probability of being cured depends very much on the stage of your cancer.
For example, in all cancers, patients with stage 1 disease have better survival rates than patients with stage 2 disease. And patients with stage 2 disease have better survival rates than patients with stage 3 disease. And stage 3 patients have better survival rates than stage 4 patients.
That's why it's so critical for you to know what stage of the disease you have.
What is 5 year survival?
When doctors quote the probability of survival, they don't tell you that you're supposed to live 3 years and 3 months. Instead, they quote you a figure that’s called the 5 year survival. This number represents the probability that someone with your disease will be alive at the end of 5 years.
For example, if the 5 year survival is 25%, this means that the odds of being alive after 5 years are 25%. It’s important to look at the particular group of patient for whom the 5 year survival is being quoted. For example, it could include all patients with a certain type of cancer or it could only include patients with a certain stage of that cancer.
For example, 49 percent, or about half, of people diagnosed with early-stage lung cancer live for at least five years after diagnosis. So, the five year survival for early-stage lung cancer is 49%. Contrast this with the five year survival rate for people diagnosed with lung cancer that has spread (metastasized) to other areas of the body which is only 3 percent.
So, as you can see, you want to find out what the survival rate is for patients with the same stage of disease.

If you think you have to follow strict rules or suffer to lose weight, think again. The easy way to lose weight is to indulge your weaknesses.Sounds crazy, doesn't it? But when I finally understood this concept, I understood why most diets fail us. That's right. The diets fail us.Because they force us to follow rules that go against human nature.It's really quite simple. The more you can't have something, the more you want it. Until you become absolutely obsessed.Think about it.Suppose you like to snack at night. If you follow a diet that eliminates snacks

When you launch a new website you must register a unique domain name with an authorized registrar. When the internet was first starting, all domain names and IP addresses were registered through one organization, Internic. Eventually Network Solutions took over the role as “keeper” of the internet domain names. Today, there are hundreds of websites where you can register your domain name but Network Solutions still maintains the main database of domain names. Some websites charge as little as $2.95 per year for your domain name while others charge as much as $35 per year for the exact same

In this era of superior technology, educational toys dime a dozen. To buy the apt toy for your little one is a difficult task. Every parent wants their child to excel in their academic and professional life. Therefore, they are always on the look out for the perfect toy, which will complement their child's age and enable to enhance their educational capability.The different toys have their own ways of teaching and educating. The toys actually strengthen their understanding of reading, building, specializing in tasks and following instructions. The simple coloring books, plastic pieces

It's official: your baby can actually talk from birth! A breakthrough in baby communication shows that your baby uses 5 simple sounds or 'words', within cries to communicate with you. These words have been dubbed 'Universal Baby Language', as tests show the same few sounds are reflex reactions used by all babies under 3 months old.This miraculous discovery was made by mother Priscilla Dunstan, who has had a photographic memory for sound since she was a child. From the age of 4, she could listen to and memorize an entire concert performance, then play it back note for note on a piano.<
So, as you can see, you want to find out what the survival rate is for patients with the same stage of disease.
What is remission?
Remission refers to a shrinking of a cancer. Remissions can either be complete or partial depending on whether or not any evidence of cancer remains. Obviously, if no cancer can be found after treatment then the remission is complete.
If the cancer is smaller but hasn’t disappeared completely then the patient has experienced a partial remission.
A complete remission may represent a cure. But there is still a chance that the cancer will return depending on the type of cancer. In people who achieve only partial remissions, the cancer nearly always regrows.
Are there any other statistical terms I should be aware of?
The 5 year survival rate tells you how many people are alive at the end of 5 years but it doesn’t tell you how many of these people are in complete remission at the end of 5 years (in other words how many people have survived for 5 years and have no evidence of cancer).
So here are two more specific terms:
Disease-free 5 year survival rate. This is the percentage of people who are not only alive after 5 years but are in complete remission.
Progression-free 5 survival rate. This is the percentage of people who are alive after 5 years but who still have evidence of cancer, although the cancer isn't progressing. This includes people who may have had some success with treatment but not enough to completely eradicate their cancer.
Two other statistical terms that you should be aware of are relative risk and absolute risk:
Absolute Risk Reduction Or Benefit. This is the absolute difference in results between alternatives. So, for example, if treatment A increased survival by 22% and treatment B increased survival by 20% then treatment A resulted in an absolute benefit of (22%-20%) = 2%.
Relative Risk Reduction Or Benefit. This is the relative difference in results between alternatives. So, in the above example, the relative benefit is (22%-20%)/20% = 10%. This number is calculated by taking the difference in outcome as a percentage.
You should beware that often results are presented as relative risk reduction or benefit because the numbers sound more impressive. For example, in the above example, a relative benefit of 10% sounds more impressive than an absolute benefit of 2%.
Hopefully, now you’ll be able to be a little more discerning about cancer statistics.
