A carcinogen is something that can cause cancer, yet this doesn't mean that it necessarily will if you're exposed to it. Carcinogens do not cause cancer at all times and under all circumstances. The ability of a carcinogen to cause cancer depends on many factors, including the amount of exposure and the length of exposure. It also depends on your individual health and other factors in your life that either raise or lower your risk of cancer. This includes personal susceptibility to a carcinogen based on your genetic makeup.1 While many cancers are caused by a carcinogen or combination of carcinogens, the tendency to develop cancer may also be inherited as part of your genome, or your set of genes. This is known as having a genetic predisposition or genetic susceptibility. A genetic predisposition means that under certain conditions and exposures you are more likely to develop cancer.
DNAcarries genetic information in cells and carcinogens cause cancer by damaging the cells DNA in either direct or indirect ways. A carcinogen can directly damage the DNA and cause changes called mutations. These changes in turn lead to a disruption in the normal process of growth and cell division. Other times a carcinogen may cause damage and inflammation, which results in the cells dividing more rapidly. When cells divide there is always a chance that a mutation will occur, which in turn increases the chance of developing a cancer. It's important to note that cancer is most often caused by an accumulation of mutations, rather than a single insult, and for this reason, a number of factors may work together to either increase or decrease the risk of developing cancer.2 Even when damage to DNA occurs, your body can produce proteins that either repair damaged DNA or eliminate damaged cells before a normal cell is transformed into a cancer cell. There are tumor suppressor genesthat sl...
Carcinogens can occur in a range of indoor or outdoor environments. They include chemicals, viruses, medications, and pollutants.3 Some carcinogens are linked to specific types of cancer.
There are several agencies and programs that classify carcinogens based on the evidence available. Each of the systems in place define carcinogens in slightly different ways. The Environmental Protection Agency: 1. Group A: Carcinogenic to humans 2. Group B: Likely to be carcinogenic to humans 3. Group C: Suggestive evidence of being carcinogenic to humans 4. Group D: Inadequate information to assess carcinogenicity 5. Group E: Not likely to be carcinogenic to humans International Agency for Research on Cancer: 1. Group 1: Carcinogenic to humans 2. Group 2A: Probably carcinogenic to humans 3. Group 2B: Possibly carcinogenic to humans 4. Group 3: Not classifiable as to its carcinogenicity in humans National Toxicology Program 1. Known to be carcinogenic to humans 2. Reasonably anticipated to be carcinogenic to humans
It is not always easy to determine if a substance or an exposure is a carcinogen. While testing for carcinogens has been done for a number of substances, the process is expensive and also sometimes complicated by long latency periods, which is the time between an exposure and the development of cancer. A good example of this is smoking. It took many years of research and millions of dollars to determine the relationship of smoking to lung cancer. It would be unethical to expose people to a suspected carcinogen and then see if they get cancer, Instead, many studies to evaluate substances for carcinogenicity are done on animals using high exposures.11 Prior to animal testing, many of these substances are first looked at in cell cultures in a lab. Retrospective studies also take a look at people with cancer and their prior exposures to try to determine which factors may be linked to cancer. Unfortunately, cell studies or animal studies cannot always tell us what will happen in human be...
Keep in mind that not every substance that is a potential carcinogen has been tested. For this reason, it's important to practice discretion with any potential carcinogens to which you may be exposed. Safety tips include to: 1. Read labels and check out ingredients if you are not familiar with them. Some home products make a note that they contain human carcinogens. An example is some types of brass cleaner. 2. Follow directions for safe handling of chemicalsat home. Read the small print on containers. Some of these recommend wearing gloves. Others recommend good ventilation, wearing a mask, or even donning a special ventilation mask. 3. If you wouldn't eat it, use gloves to handle it.Many substances can be absorbed easily through the skin. (We now have patches for everything from nicotine to pain medications that take advantage of this process.) 4. Follow recommended procedures at work when handling chemicals on the job. Employers are required to provide Material Safety Data Sheets...
Carcinogens cause cancer by damaging your cell's DNA or by causing damage and inflammation that leads to mutations. Carcinogenic exposures can come from home chemicals, environmental or medical radiation, medications, viruses, polluted air, or lifestyle factors. There are also many complex factors involved in the development of cancer and just because you are exposed to a carcinogen does not mean it will necessarily result in cancer.
Carcinogens are a part of daily life. Taking action to lower your exposure to known carcinogens, whenever possible, is a great start. Take some simple safety precautions, such as reading labels and wearing gloves when handling chemicals. Try to focus on lifestyle factors, such as exercising and not smoking, that are within your control. It's also important to stay informed and pay attention to new research and warnings since there are likely carcinogens that haven't yet been identified.
