I always wondered what came first, genes that cause cancer or products that changed genes
Carcinogenic exposure circumstances
1 Tobacco smoking: The most common exposure to the stimulant, prepared from the leaves of the tobacco plant, is through burning it and smoking it from a cigarette or hookah pipe into the mouth and then releasing it. Smoking’s history dates back to as early as 5000–3000BC when the agricultural product began to be cultivated in South America.
2 Sunlamps and sunbeds: A tanning bed, a device that emits ultraviolet radiation for a cosmetic tan, can give humans overexposure to UV radiation, which can cause skin cancer, cataracts, and premature skin ageing.
3 Aluminium production: Increased lung and bladder cancer risks have been reported in workers in aluminium reduction plants. The fumes of chemicals the workers may inhale, and exposure to coal-tar pitch volatiles for long periods during the process, can cause cancer.
4 Arsenic in drinking water: The highly toxic chemical which is used to make certain alloys used in the manufacturing industry, can get into the drinking water supply, particularly in ground water. Arsenic is known to cause skin cancer, and linked to causing liver, lung, kidney, and bladder cancer.
5 Auramine production: Auramine can be used as an antiseptic agent as well as to make dyes. A study found there to be an
excess of bladder tumoursamong men engaged in the manufacture of auramine, through inhaling harmful agents, such as formaldehyde and sulphur, during the manufacturing process.
6 Boot and shoe manufacture and repair: Linked to
increased risk of nasal cancer and leukaemia, due to exposure to suspected carcinogens such as leather dust, benzene and other solvents, yet the risk of cancer in shoe manufacturing may vary depending on the duration and level of exposure.
7 Chimney sweeping: Cleaning chimneys of soot and dust, historically done by small boys who could climb the chimney but now done mechanically, could cause a very specific form of cancer – termed “chimney sweep” cancer. It could be caused by inhalation and accidental ingestion of coal and burnt wood fumes and residue.
8 Coal gasification: Studies of the cancer levels of workers who had occupational exposure to coal gasification – when coal is reacted with oxygen, steam and carbon dioxide to form a gas – showed there to be an excess of lung cancer.
9 Coal tar distillation: Derived from coal, coal-tar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products. Both coal tar and coal-tar pitch contain many chemical compounds, including carcinogens such as benzene. Human exposure to coal tars can be through inhalation, ingestion, and absorption through the skin. The general population can be exposed to coal tars in environmental contaminants.
10 Coke (fuel) production: Workers at coking plants and coal-tar production plants – where coal is refined to be used as a solid fuel – may be exposed to coke oven emissions, and have an
excess risk of dying from lung cancer and kidney cancer.
11 Furniture and cabinet making: Furniture makers are shown to have a
statistical increase in nasal cancer risk, with excessive exposure to wood dust, according to studies.
12 Haematite mining (underground) with exposure to radon: Mining hematite, an underground source of iron, workers are simultaneously exposed to radon – a radioactive carcinogen, which can cause a
large increase in the risk of lung cancer.
13 Secondhand smoke: Otherwise known as passive smoking, a non-smoker’s risk of getting lung cancer can increase by a quarter by breathing in other people’s smoke. It may also increase the risk of cancers of the larynx (voice box) and pharynx (upper throat). It’s estimated that
every year, secondhand smoke kills over 12,000 people in the UK from lung cancer, heart disease, stroke and the lung condition chronic obstructive pulmonary disease.
14 Iron and steel founding: Studies of iron and steel founding workers in various parts of the world showed them to have a
significantly increased risk for lung cancer. Exposures in the iron and steel founding industry are complex and include a wide variety of known genotoxic and carcinogenic substances including metals and formaldehyde.
15 Isopropanol manufacture (strong-acid process): People in the isopropanol manufacturing industry may face an increased risk of
developing cancer due to exposure to suspected carcinogens, such as diisopropyl sulphate, isopropyl oils and sulphuric acid. The colourless, flammable chemical compound with a strong odour has a wide variety of industrial, household and pharmaceutical uses. Isopropyl alcohol solution is found in rubbing alcohol, hand sanitiser, and disinfecting pads.
16 Magenta dye manufacturing: The production of magenta dyes – purplish-red in colour and among the first synthetic dyes to be produced in the 1850s –
has chemicals linked to bladder cancer. Yet some carcinogenic chemicals were banned from hair dyes in the 1970s.
I think there are another 100
And I don't think it even includes all the additives we eat from processed foods.
But I suppose we can use the Adam syndrome and blame God for what man does.
