It has been estimated that exposure to environmental chemical carcinogens may contribute significantly to the causation of a sizable fraction, perhaps a majority, of human cancers. Human carcinogens act through a variety of genotoxic and non-genotoxic mechanisms. Genotoxic carcinogens can attack biological macromolecules such as DNA and RNA either directly or indirectly through metabolism, resulting in the formation of adducts with these macromolecules. If DNA adducts escape cellular repair mechanisms and persist, they may lead to miscoding, resulting in permanent mutations. Non-genotoxic carcinogens act by the mechanisms such as induction of inflammation, immunosuppression, formation of reactive oxygen species, activation of receptors, and epigenetic silencing. Together, these genotoxic and non-genotoxic mechanisms can alter signal-transduction pathways that finally result in hypermutability, genomic instability, loss of proliferation control, and resistance to apoptosis - some of the ...

When carcinogens are involved at the workplace, employers have to do everything in their power to prevent workers coming into contact with these substances.
Today, the House Science, Space, and Technology Committee and House Small Business Committee held a joint hearing on the National Toxicology Programs (NTP) Report on Carcinogens. It is critical that the NTP use the best available, peer reviewed science when making its decisions on what chemicals to list, yet it clearly doesnt do that.

Definition of non-genotoxic carcinogen and genotoxic carcinogens and whether there are any thresholds for carcinogens from a regulatory perspective.
A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis, the formation of cancer. This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise in both natural and synthetic substances.[1] Carcinogens are not necessarily immediately toxic; thus, their effect can be insidious. Cancer is any disease in which normal cells are damaged and do not undergo programmed cell death as fast as they divide via mitosis. Carcinogens may increase the risk of cancer by altering cellular metabolism or damaging DNA directly in cells, which ...

Figure 5. NNK administration differentially stimulates GM-CSF secretion in vitro and in vivo. A, RNAs obtained from PanIN cells treated with NNK (1 μmol/L) or DMSO (control) for 5 and 50 days, respectively, were subjected to RNA-seq analysis. The differentially expressed genes between the control and treatment groups were determined using hierarchical clustering and subsequent heat map generation of normalized gene expression in standardized units. Data analysis using IPA revealed the upregulated genes in the treatment group (red). B, qPCR data of RNA collected from PanIN cells (top) and H6c7 cells (bottom) treated with NNK (1 μmol/L) or DMSO (control) for 50 days and analyzed to validate the genes upregulated in RNA-seq data (n = 3).

American baby care products are not as safe as consumers may expect. The Campaign for Safe Cosmetics released a report on 48 baby care products that were tested for the carcinogens formaldehyde and 1,4-dioxane. The March 2009 report, entitled No More Toxic Tub, reveals that 67 percent of the products tested contained detectable levels of 1,4-dioxane. 82 percent of the products tested contained detectable levels of formaldehyde and 1,4-dioxane. And 61 percent of products tested contained both.. Of the 48 products tested, only 28 were tested for formaldehyde. So theres a chance that if all products had been tested for both, the percentage of products contaminated with both could be higher than 61 percent.. The State of California classifies both chemicals as carcinogens under its Proposition 65 The Safe Drinking Water and Toxic Enforcement Act of 1986 passed in 1986. Both were listed as carcinogens on January 1, 1988. The US EPA regards both as probable carcinogens ...
Learn how potential carcinogens are tested and classified, find lists of known and possible carcinogens, and learn about cancer clusters.
Researchers for the first time have developed a method to track through the human body the movement of polycyclic aromatic hydrocarbons, or PAHs, as extraordinarily tiny amounts of these potential carcinogens are biologically processed and eliminated.
Lung cancer is strongly associated with exogenous risk factors, in particular tobacco smoking and asbestos exposure. New research data are accumulating about the regulation of the metabolism of tobacco carcinogens and the metabolic response to oxidative stress. These data provide mechanistic details about why well known risk factors cause lung cancer. The purpose of this review is to evaluate the present knowledge of the role of cytochrome P450 (CYP) enzymes in the metabolism of tobacco carcinogens and associations with tobacco and asbestos carcinogenesis. Major emphasis is placed on human data and regulatory pathways involved in CYP regulation and lung carcinogenesis. The most exciting new research findings concern cross-talk of the CYP-regulating aryl hydrocarbon receptor with other transcription factors, such as nuclear factor-erythroid 2-related factor 2, involved in the regulation of xenobiotic metabolism and antioxidant enzymes. This cross-talk between transcription factors may provide mechanistic

Researchers presenting at the 242nd National Meeting and Exposition of the American Chemical Society this week in Denver have demonstrated a new DNA test that can measure the amount of potential carcinogens clinging to a persons DNA. But unlike previous tests that required white blood cell or urine samples and fairly intensive lab scrutiny, this one can hunt for carcinogens in a simple saliva swab.
Based on extensive reviews of research studies, there is a strong scientific consensus of an association between alcohol drinking and several types of cancer. In its Report on Carcinogens, the National Toxicology Program of the US Department of Health and Human Services lists consumption of alcoholic beverages as a known human carcinogen. The research evidence indicates that the more alcohol a person drinks particularly the more alcohol a person drinks regularly over time, the higher his or her risk of developing an alcohol-associated cancer. It will shock you to know that the effects are very fatal when accounting for deaths resulting from the consumption of alcohol. From the available statistics, it was estimated that in 2009 about 3.5% of cancer deaths in the United State, were alcohol related. That percentage represents about 19500 people dying from this scourge.. Request more information on screening and treatment of Alcohol and cancer today: Call (843) 213-1480 or contact online..

p,,b,BACKGROUND: ,/b,The aim of this work was to establish recommendations for the medical follow-up of workers currently or previously exposed to lung carcinogens.,/p,,p,,b,METHODS: ,/b,A critical synthesis of the literature was conducted. Occupational lung carcinogenic substances were listed and classified according to their level of lung cancer risk. A targeted screening protocol was defined.,/p,,p,,b,RESULTS: ,/b,A clinical trial, National Lung Screnning Trial (NLST), showed the efficacy of chest CAT scan (CT) screening for populations of smokers aged 55-74 years with over 30 pack-years of exposure who had stopped smoking for less than 15 years. To propose screening in accordance with NLST criteria, and to account for occupational risk factors, screening among smokers and former smokers needs to consider the types of occupational exposure for which the risk level is at least equivalent to the risk of the subjects included in the NLST. The working group proposes an algorithm that estimates ...

What Carcinogens Are You Avoiding? - posted in Cancer: Are there any substances besides the obvious (smoking, being overweight, excess alcohol, exhaust fumes) that you are avoiding to prevent cancer? Are there any substances that are legally in the global food supply (preservatives, colorings and the like) that you are fairly convinced increase the probability of cancer and are therefore avoiding?
Tumor promotion is a critical event in cancer development and a potential target for chemopreventive measures. The multistage model of mouse skin carcinogenesis defines tumor development in terms of distinct stages and provides a standardized scheme for the investigation of tumor promoters. By using this model, a specific COX-2 inhibitor, celecoxib, was found to inhibit tumor formation by interfering with the promotion stage. Although COX-2 has been shown to catalyze the formation of genotoxic metabolites from polycyclic hydrocarbons (19), tumor initiation in skin by DMBA is not affected by celecoxib, whereas DMBA-induced breast cancer in rats was inhibited by this drug (7). Inhibition of postinitiation stages has also been observed for chemically induced colorectal carcinogenesis in rats (20). Thus, these studies indicate that COX-2 is involved in the promotion of both mouse skin and rat colon tumors.. As shown previously (15), transgenic overexpression of COX-2 in basal keratinocytes of mice ...
Because the scope of Volume 100 is so broad, its Monographs are focused on key information. Each Monograph presents a description of a carcinogenic agent and how people are exposed, critical overviews of the epidemiological studies and animal cancer bioassays, and a concise review of the agents toxicokinetics, plausible mechanisms of carcinogenesis, and potentially susceptible populations, and life-stages. Details of the design and results of individual epidemiological studies and animal cancer bioassays are summarized in tables. Short tables that highlight key results are printed in Volume 100, and more extensive tables that include all studies appear on the Monographs programme website (http://monographs.iarc.fr ...

The main targets for antineoplastic drug in development are colorectal cancer, non-small cell lung cancer, breast and ovarian cancer. This reflects the frequency of the diseases. Lung cancer is the most common type of cancer, causing 24% of cancer deaths in UK males and 19% in females. Breast cancer and prostate cancer are the next most common cancers at 17% and 13% in the UK, while colorectal cancers account for around 10% of UK cancer deaths. There is also interest in drugs effective against less prevalent forms of cancer, partly because they may eventually provide treatments for other cancer types. The toxicity of many current antineoplastic is a major concern. Drugs which interfere with DNA and the cells ability to divide are also likely to introduce mutations, and are therefore potential carcinogens. For example, cyclophosphamide is listed as a human carcinogen and cisplatin as a probable carcinogen, by the International Agency for Research on Cancer. This means that these drugs can lead ...

When considering the nutritional value of our meals, we have been trained to pay close attention to numbers such as fat content and calories. What we dont often think about is if there is something in our food that could be causing us cancer. Substances that can lead to cancer are called carcinogens, and you may be surprised to find out that these harmful chemicals can be found in your everyday foods.. Carcinogens enter your diet through the way your food is processed, environmental exposures, and even certain types of packaging. The safest way to [avoid carcinogens] is to buy organic whole foods and cook them yourself, says Susan Machtinger, RD.. Because no one wants to consume cancer-causing chemicals, weve come up with a list of five ways that carcinogens could be making their way into your food. ...

Limited daily exposure to toxins is tough in a pretty toxic world, but its a reasonable expectation that we all want to kick known carcinogens out of our homes. To that end, we asked Cara Bondi, a green scientists at Seventh Generation,
We compared effects of a high fat diet and a carcinogen on cellular elements of the spleen and mammary gland tumors in rats. Animals were fed a 15% olive-oil diet and a group of them were exposed to a carcinogen, dimethylbenz(a)antracne (DMBA), in two doses of 10 mg/rat. Results of the experiments were evaluated after 4 months. We studied changes in the areas of different zones of the spleen related to production of B and T lymphocytes and also the number of cells in the spleen and tumors with positive reaction to receptors related to manifestation of apoptosis (FasL and p53) and receptors related to inhibition of apoptosis (bcl-2). In the spleen, dietary fats as well as DMBA alone decreased the zones related to production of B lymphocytes and increased the number of T lymphocytes. The combined effect of a carcinogen and a high fat diet manifested in an increase in the number of lymphoid cells and macrophages. In tumors from rats fed a low-fat diet, an extremely high number of lymphoid cells was ...
