No, this has no credibility whatsoever, for a number of very good reasons, each of which on its own would be sufficient to debunk the hypothesis: Individual motivation: people don't get into cancer research to get rich, but because they want to cure cancer, and for the prestige ("Among the factors that motivate researchers, the excitement of discovery stood ...

According to the US CDC: People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke According to Carcinogenicity of consumption of red and processed meat (Lancet 2015) citing to Red and Processed Meat and Colorectal Cancer Incidence: Meta-Analysis of Prospective Studies (2011): ...

The cancer.gov site you referenced says that the median age of diagnosis is 70. That implies that you smoke and then, later in life/time, you may be diagnosed with cancer. Therefore, for example, Lung cancer incidence statistics from the UK says: Trends in lung cancer incidence rates reflect past trends in cigarette smoking prevalence. Smoking rates ...

There are several points to consider here. 1) Depleted Uranium is not that much "depleted". "Depleted uranium," the byproduct of the enrichment process, has about 0.002 percent 234U, 0.2 percent 235U and 99.8 percent 238U, and about 60 percent of natural uranium's radioactivity. -- U.S. Office of the Secretary of Defense, emphasis mine. 2) Uranium is ...

Does the claim “processed meat causes as much cancer as smoking in relative terms” hold up to scrutiny? No, it does not. The WHO did indeed classify processed meat as carcinogenic to humans. Going to the source, http://www.who.int/features/qa/cancer-red-meat/en/, 9. Processed meat was classified as carcinogenic to humans (Group 1). Tobacco smoking and ...

I don't have much to say here, because Cancer Research UK have already written a winning answer. (Sometimes the giants are tall enough that there's no need to stand on their shoulders.) If you visit Tobacco, smoking and cancer: the evidence you will find explanations of all these facts: Smoking is the single biggest cause of cancer in the world ...

To the best of my knowledge, the paper cited by the BBC is "Vanilloid receptor agonists and antagonists are mitochondrial inhibitors: how vanilloids cause non-vanilloid receptor mediated cell death" (PMID: 17214968 DOI: 10.1016/j.bbrc.2006.12.179), which lists Timothy E Bates as an author (the last one, which means he was the primary investigator -- h/t Mad ...

There have been a number of case-control studies on Chinese women. Here are three open-access papers: Ko et al. (2000). "Chinese Food Cooking and Lung Cancer in Women Nonsmokers". Amer. J. Epidemiology 151(2) pp. 140–147. The subjects were 131 nonsmoking incident cases with newly diagnosed and histologically confirmed primary carcinoma of the lung, 252 ...

Ok, there appears to be something to this. The description of how they claim it works is pure word salad. Nevertheless I've been surprised checking this out, this would appear to be one of those rare cases where they've picked up on something that's actually getting used in cancer treatment. It does not cure cancer but it may be part of a useful treatment. ...

Check out this paper: Cancer mortality in Serbia, 1991–2015, published in 2018. The study is based on official data on cancer-related deaths. The conclusions drawn by the authors are: Overall cancer mortality rate (ASR - age-standartized rate) increased between 1991 and 2009 by 0.8-0.9% per year. After 2009, the trend changed to decline, again by 0.9% per ...

There is no evidence that the acrylamide produced by browned food causes measurable harm to people The big worry about browning or burning food is the presence of acrylamide which is produced by the reaction of sugars and amino acids (via the Maillard reaction which also produces many of the attractive flavours of cooked food). The UK Food Standards ...

The answer is yes, in laboratory experiments, and perhaps in a clinical setting as well. Let me emphasize: the proof exists in controlled laboratory experiments. It has not been demonstrated to be true in human trials. So don't smoke up in the expectation that it's a better cancer treatment than a doctor's recommendations (generally chemotherapy, ...

No. This result is a blatant misrepresentation of what the study1 actually did, namely cataloguing changes in behaviour in the cells surrounding a tumour when exposed to anticancer treatment, and how those changes affect the resistance of the tumour to the treatment. Cancer Research UK calls the headlines “misleading” and warns not to take them seriously. ...

When there is doubt about individual studies, the place to go is a meta-study - one that looks at many different experiments, evaluates the quality according to a strict methodology, and pools the results to get stronger statistical findings. Here's one from 2007: Meta-analysis of studies of passive smoking and lung cancer: effects of study type and ...

There are 20 countries in Latin America1, of which 5 have had cases of leaders with cancer (one country, Brasil, had two cases). This equates to 6 in 20 cases, or ~33% incidence of the disease. Note that the original article does not include Fidel Castro in the list of cancer victims, I did. Is this figure "difficult to explain using the law of ...

Short summary (source: recent review in the BMJ) Major evidence based guidelines recommend against the prostate specific antigen (PSA) blood test for prostate cancer screening because: The test is unlikely to prevent you from dying of prostate cancer over 10-15 years or help you live longer Elevated PSA values are common and lead to additional ...

Summary cancer only grows in acidic bodies ... an alkaline body can prevent or cure cancer. This is certainly over-simplistic, probably meaningless, almost certainly useless. Average body pH I suspect this is not a meaningful thing to attempt to measure. In terms of cancer, it may be no more meaningful than average body thickness, average body density ...

Women patients with metastatic breast cancer (for example) lived much longer after diagnosis in 1995 compared to 1920. This 1983 study describes an interesting aspect to this question: Survival of women with metastatic breast cancer at Yale from 1920 to 1980. Todd M, Shoag M, Cadman E., J Clin Oncol. 1983 Jun;1(6):406-8. The survival of metastatic breast ...

Do "elephants have 40 cancer-fighting proteins in their DNA?" Elephants have 40 copies of a single cancer-fighting protein. This means they have a lot more of that protein than humans. Do elephants rarely get cancer? They get cancer about as much as other animals. The fact that they don't get cancer more is surprising because they are big and long lived. ...

The US Anti-Doping Agency (USADA) produced a report on its decisions against Armstrong. One of the key pieces of evidence against Armstrong was the testimonial of fellow cyclist Frankie Andreu about what he heard in an Indiana hospital room, while Armstrong was being treated for cancer. That testimony was initially challenged by Armstrong. However, one ...

Yes, most pregnancy tests detect human chorionic gonadotropin (hCG), a hormone produced by fertilized eggs, but also by some kinds of cancer cells. You can read more about different tumor markers on this info page from "The American Cancer Society". There are also several other situations where a pregnancy test may give a false positive result (both for ...

There is no consistent evidence showing a relationship between glyphosate and cancer There are a lot of studies on the relationship between glyphosate use and cancer. Some are small and poor; others are large and more reliable. It is inevitable and likely that some of these studies will report a connection between the weedkiller and cancer just through ...

According to this wikipedia article no case of a cancer cure by Hamer has been published in the medical literature, nor any studies in specialised journals. Reports in his books "lack the additional data that are essential for medical assessment" and the presentations, of his investigations, at medical conferences "are scientifically unconvincing". and: ...
