Detecting Cancer – Can You Trust All the Tests?

Obviously, a false diagnosis of cancer would be a disaster.

I’m not talking about all tests for cancer. I’ve only looked into two. This is what I’ve discovered.

There is a blood test, which looks for a bio-marker labeled CA125. There are doctors who will tell you that a highly positive result indicates a high probability of cancer.

Imagine being a patient on the receiving end of that news.

But wait. If you go to other sources—and no, I’m not talking about alternative practitioners, I’m talking about the mainstream—you’ll get a distinctly different view.

How about a quite prestigious organization—the Mayo Clinic?

“A CA 125 test measures the amount of the protein CA 125 (cancer antigen 125) in your blood.”

“A CA 125 test may be used to monitor certain cancers during and after treatment. In some cases, a CA 125 test may be used to look for early signs of ovarian cancer in people with a very high risk of the disease.”

“A CA 125 test isn’t accurate enough to use for ovarian cancer screening in general because many noncancerous conditions can increase the CA 125 level.”

“Many different conditions can cause an increase in CA 125, including normal conditions, such as menstruation, and noncancerous conditions, such as uterine fibroids. Certain cancers may also cause an increased level of CA 125, including ovarian, endometrial, peritoneal and fallopian tube cancers.”

“Your doctor may recommend a CA 125 test for several reasons: But such monitoring hasn’t been shown to improve the outcome for those with ovarian cancer, and it might lead to additional and unnecessary rounds of chemotherapy or other treatments.”

“…some people with ovarian cancer may not have an increased CA 125 level. And no evidence shows that screening with CA 125 decreases the chance of dying of ovarian cancer. An elevated level of CA 125 could prompt your doctor to put you through unnecessary and possibly harmful tests.”

“A number of normal and noncancerous conditions can cause an elevated CA 125 level, including:
• Endometriosis
• Liver disease
• Menstruation
• Pelvic inflammatory disease
• Pregnancy
• Uterine fibroids”

“None of the major professional organizations recommend using the CA125 as a screening test for those with an average risk of ovarian cancer.”

Is that clear enough? I hope so.

Let’s move on to another test for cancer. It’s a version of a PET scan.

From acrin.org, About PET Scans: “A PET scan uses a small amount of a radioactive drug, or tracer, to show differences between healthy tissue and diseased tissue. The most commonly used tracer is called FDG (fluorodeoxyglucose), so the test is sometimes called an FDG-PET scan. Before the PET scan, a small amount of FDG is injected into the patient…”

The theory goes this way: cancer cells have an affinity for FDG and “grab on to” it. Thus, these cancer cells “light up” on the PET scan and can easily be seen. Tumors and metastases can be observed.

Yes, but…

Introduction to PET/CT Imaging: “Cancer cells are not always the only ‘PET avid cells’ (or cells that take up the FDG) in the body. It is important to remember that a PET scan is not able to distinguish metabolic activity due to tumor from activity due to non cancerous processes, such as inflammation or infection.”

PET scan findings can be false positive: “In cancer cells, there is an overproduction of glucose transporters and, as a result, increased FDG uptake. However, not all PET-positive lesions are cancer, and in many instances, PET findings can be false positive. … Inflammatory cells also have increased metabolic rates and, as a result, are FDG avid.”

“Many of us have had patients or know of patients who were treated by the medical oncologist for stage IV cancer only to find out what was assumed to be a metastatic lesion was benign on pathology. Other patients have undergone multiple biopsies of supposed metastatic mesenteric lymph nodes that subsequently turned out to be fat necrosis or a granulomatous reaction. FDG-positive lesions often mean cancer, but not always. A variety of lesions have increased FDG radiotracer [the “lighting up” phenomenon] including infection, inflammation, autoimmune processes, sarcoidosis, and benign tumors. If such conditions are not identified accurately and in a timely manner, misdiagnosis can lead to inadequate therapies.”

Causes and imaging features of false positives and false negatives on 18F-PET/CT in oncologic imaging: Causes and imaging features of false positives and false negatives on 18F-PET/CT in oncologic imaging“Glucose however acts as a basic energy substrate for many tissues, and so 18F-FDG activity can be seen both physiologically and in benign conditions. In addition, not all tumors take up FDG [3–5]. The challenge for the interpreting physician is to recognize these entities and avoid the many pitfalls associated with 18F-FDG PET-CT imaging.”

The question is, after a patient is told he has received a positive PET scan, indicating cancer, will the physician spell out all the factors that could have made the test read FALSELY POSITIVE? Will an intelligent and honest and informed conversation take place, or will the doctor shove the test results at the patient and declare: “You have cancer.”

And if that cancer diagnosis is given, will the patient be in a position to voice questions through prior knowledge, and undertake a reasonable dialogue with his doctor?

How do doctors normally hand down test findings? In a balanced way, or from on high, with all the presumed authority of unchallengeable experts?

Are there doctors who don’t even know these two diagnostic tests are rife with falsely positive readings? Yes, there are. And if they deliver papal edicts based on their ignorance, they can cause great harm.

Misinformation on how Americans depend on the Russian RD-180 engine

Having seen television programs, where various “experts” appear, the average person automatically becomes an “expert” and calmly falls asleep with thoughts about how a decaying America cannot fly into space without the legendary Russian RD-180 engine.

Is there really a dependency? Why don’t the Americans banally copy the RD-180 if they are so smart?

The answer, as always, is on the surface …

Storytellers, talking about the advantages of the RD-180 and the lack of analogues in the world, deliberately keep silent about the American rocket engine RS-25, which was developed for the implementation of the Space Shuttle program. RS-25 was the main engine of the space shuttle.

The Americans do not need to copy the RD-180, if only for the reason that its parameters practically coincide with those of the RS-25.

For one combustion chamber at ground level, the RS-25 develops 182 tons of thrust, and the RD-180 – 187 tons. In a vacuum, the RS-25 already yields 223 tons against 203 tons from the Russian engine. The specific impulse of RS-25 is greater (452 ​​seconds in vacuum and 366 seconds at Earth level) than the vaunted RD-180 (338 seconds in vacuum and 311 seconds at Earth level).

Lies about how Americans depend on the Russian RD-180 engine

In addition, the RS-25, unlike the RD-180, is a reusable rocket engine: it can be turned on and off at full throttle, which, in general, was done during the launch of the Space Shuttle. RD-180 is designed for one launch.

It turns out that the Americans created an analogue of the RD-180 before the appearance of the RD-180?

Exactly! RS-25 began to be used back in 1981, and the RD-180 was born in 1999. Oh, the Americans “copied” the indispensable RD-180 18 years before its creation …

In fairness, it is worth noting that the Russian RD-180 (2 combustion chambers) is a “halved” version of the Soviet RD-170 (4 combustion chambers), which was born in 1984.

Why are Americans buying the RD-180 ?!

If scientists, engineers and maintenance personnel in the United States worked for the same salaries as their counterparts in Russia, then there would be no talk of any purchases of the RD-180.

The fact is that preparing the RS-25 for flight is an expensive event, the cost of which includes salaries of specialists.

Thus, the cost of one RS-25 is 50-60 million dollars, and the price of the RD-180 does not exceed 15 million dollars. Americans are capitalists, businessmen, and they make purchases that are very favourable to them.

RD-180 is a cheap and high-quality analogue to RS-25, which the Americans bought in huge quantities for a fraction. According to the first contract, Russia transferred the United States 101 RD-180 engine, receiving about a billion dollars for this.

The Americans saved a lot of money and repeatedly launched military satellites using these engines.

Remedies for obesity can stop the spread of cancer

Cancer is the second leading cause of death in the world after cardiovascular disease. Sometimes doctors manage to remove the primary tumors and people have the hope of a full recovery. However, if the tumor has so-called metastases and it begins to spread, the chances of a complete cure are greatly reduced. However, scientists from Belgium have been trying to find more than one year looking for a way to stop the complications of cancer, and in a recent study found that the disease spreads using human fat as an energy source. So what is it that can be done to stop the development of cancer using anti-obesity drugs?

Perhaps scientists are one step closer to creating a cure for cancer

The results of the scientific work carried out by Belgian scientists were published in the journal Nature communications. A team of scientists led by Olivier Feron continued his previous study and found that cancer cells accumulate fat in tiny vesicles, which were called lipid drops. Fats are used as an energy source, so it is logical that the cells saturated with them spread much faster than others.

How does fat contribute to cancer?

According to scientists, TGF-beta2 protein, also known as transforming growth factor beta, is responsible for the accumulation of fats in cells and the aggressive behavior of cells. It is a kind of switch that, on the one hand, allows cancer cells to accumulate energy, and on the other hand, forces them to use the received power for distribution.

Thanks to the new discovery, scientists were able to develop a new plan to slow the development of cancer. In theory, to stop the occurrence of metastases, researchers need to develop a tool to block the production of TGF-beta2 protein. It would also be nice if the future medicine slowed down the formation of fats and their transportation throughout the body. Just before that, they need to make sure that the TGF-beta2 protein is not involved in other processes important for human life. Also, people taking the medicine, which is essentially a remedy for obesity, will have to adhere to a certain diet.

Fat is a source of energy for cancer cells.

It is possible that in the world there are already drugs suitable for these purposes. It is important for scientists only to study their composition and experimentally check whether they are really able to slow down the development of cancer. Typically, such tests are first performed on laboratory mice. For example, in 2018, scientists introduced a tiny human brain into the body of a rat and looked, what came of it.

In general, cancer can be defeated by turning cancer cells into fat cells. According to the scientific journal Cancer cell In 2019, Swiss scientists led by Professor Gerhard Cristofori were also able to prevent cancer complications in this way. By the way, they conducted an experiment on mice with aggressive breast cancer. This cancer is often found in women, so the discovery can be considered very important for the scientific community.

By 2024 GM And Michelin Will Bring Airless Tires To Passenger Cars

By Mayukh Saha / Truth Theory

Michelin and GM had unveiled a novel wheel technology- Uptis (Unique Puncture-proof Tire System) in the year 2019. The airless tires are in the preliminary stage currently, but there is a chance of them being rolled out by 2024.

The vice-president of General Motors said that the company is excited to see what all Uptis can do. He also said that the collaboration with Michelin is thrilling.

The rubber tires currently used are prone to dangers like blowouts but the airless tires will eliminate such problems. They will also be low-maintenance as people won’t need to check them for punctures and pressure.

Another big advantage of this high-technology is that the number of tires that are wasted will decrease. Also, the amount of raw material used to make rubber tires will go down along with the energy required to build those tires. It will be beneficial as far as sustainability is concerned, believe the creators.

Uptis tires will also be more durable because they won’t undergo damage easily. Unlike the rubber tires that get damaged by the excess or lack of air, these airless tires will have no such issues.

The CEO of Michelin, Menegaux said that Uptis supports the company’s dream of making mobility sustainable. According to him, working with GM, the company can conquer the future now.

Michelin’s VISION Concept Tire is a 4 pillar strategy to conduct R&D and bring sustainability in mobility. Uptis is the first step first in this direction.

The intention with which GM is working is to introduce the airless tires in passenger vehicles by 2024. However, the details about Uptis aren’t been out yet. Neither of the companies is willing to share the details about this wheel technology.

It’s not clear what material is used to make these tires. It’s also unknown how they’ll function. Any noticeable difference has also not been mentioned.

Michelin said in its FAQs that Uptis has a common concept as that of their Tweel technology. The latter is a tire-wheel assembly where ‘spokes’ are to bear the weight and there is an outer rim.

General Motors was expecting to start testing the airless tires on the Chevrolet Bolt EVs by the end of 2019, but there are no further developments in this area.
