Cancer is a disease in which some body cells grow uncontrollably and can spread to other parts of the body.
In fact, there are hundreds of different types of cancer, and their causes are many more, some of which are known to scientists, and some are still under study or have not yet been discovered.
“Cancer-causing agents, known as carcinogens, can be of different types and forms, and they work to provoke mutations in the human body that lead to the development of cancer,” says Dr. John Oertel, chief medical director at Invita Medical Centers in Scottsdale, Arizona.
The doctor explained that while some causes, such as tobacco use and ultraviolet rays, are widely known for their harmful effects, there are many carcinogens hidden in the environment that are equally harmful.
The doctor provided a list of some of these hidden carcinogens, their sources, and the types of cancer they cause.
1. Tobacco
This carcinogen comes from cigarettes. Oertel pointed out that tobacco can cause cancer of the mouth, nose, throat, trachea, esophagus, lungs, stomach, pancreas, liver, kidneys, ureters, bladder, colon, rectum, and cervix, in addition to leukemia.
2. Organochlorine
Organochlorines are pesticides that have been used in agriculture around the world since their introduction in the 1940s, despite their high toxicity.
Although it is banned in many countries due to health risks, it is still used in other countries.
Organochlorine compounds can lead to cancer of the breast, colon, rectum, pancreas, prostate, lung, mouth/pharynx, thyroid, adrenal gland, and gallbladder, in addition to lymphoma, according to Oertel.
3. Polycyclic aromatic hydrocarbon
Polycyclic aromatic hydrocarbons (PAHs) are chemicals found in coal, crude oil and gasoline, according to the CDC. They are emitted into the environment through the burning of coal, oil, gas, wood, garbage, cigarette smoke, vehicle exhaust, roof tar, and pharmaceuticals.
Exposure to these chemicals can cause cancers of the breast, skin, lung, bladder and gastrointestinal tract.
4. Volatile organic compounds
Volatile organic compounds (VOCs) are chemicals emitted by the manufacture of paints, pharmaceuticals, and refrigerants, among other products. They are also found in industrial solvents, petroleum fuels, and dry cleaning agents.
Oertel warned that VOCs are commonly found in the air, groundwater, cigarette smoke, automobile emissions and gasoline.
It can cause lung cancer, nasopharynx, lymphoma, sinus cancer, in addition to leukemia.
5. Ultraviolet rays
The World Health Organization (WHO) classifies ultraviolet rays from the sun and tanning beds as carcinogenic to humans.
These rays can cause a variety of skin cancers, including basal cell carcinoma, squamous cell carcinoma, and melanoma.
6. Radon
Radon is a radioactive gas, a byproduct of uranium, thorium or radium that decays in rocks, soil and groundwater, according to the EPA.
Ortel said that when radon gas leaks into buildings and homes, people can inhale it, which increases the risk of leukemia, lymphoma, skin cancer, thyroid cancer, various sarcomas, lung cancer, and breast cancer.
7. Asbestos
Asbestos, a mineral fiber found in rocks and soil, has historically been used in construction materials.
Although some uses have been banned, it can still be found in insulation, roof and siding panels, vinyl floor tiles, heat-resistant fabrics and some other materials.
Oertel warned that exposure to asbestos can increase the risk of lung cancer, mesothelioma, gastrointestinal tract, colon, rectum, larynx, kidney, esophagus and gallbladder.
8. Cadmium
Cadmium is a soft, malleable, bluish white metal found in zinc ores and, to a much lesser extent, in the green metal cadmium.
Oertel said cadmium can be found in paints, batteries and plastics. The mineral can be a factor in lung, prostate, pancreas and kidney cancer.
9. Chrome
There are two types of this trace mineral, one of which is trivalent chromium, which is harmless to humans. The other, hexavalent chromium, is toxic.
Sources of harmful chromium include chrome plating, welding, leather tanning, and ferrochrome metals.
It has been shown that inhaling chromium, a known human carcinogen, causes lung cancer, especially in steel workers.
10. Nickel
Nickel is a heavy metal known to be a carcinogen, and is found in electroplating, circuits, electroforming, and batteries.
Nickel has been linked to an increased risk of lung and nasal cancer.
Three causes of premature graying
Dr. Yulia Nagaitseva, a dermatologist and hair specialist, revealed three causes of premature graying, which can be treated and restore the natural color of the hair.
The specialist indicated in an interview with Sputnik Radio that gray hair is considered premature if it appears before the age of twenty-five, as in this case the hair loses its color not due to physiological changes in the body, but rather for other reasons.
She says: “A deficiency in iron, copper, zinc, or B group vitamins can lead to premature graying. There is also a hereditary factor, which is also taken into consideration if relatives suffer from premature graying. The stress factor can also affect it.”
According to the specialist, when the first gray hairs appear, you should see a doctor. If it turns out that the problem is not hereditary, but rather due to a lack of vitamins and minerals in the diet, the condition can be treated and hair color can be restored.
She says: "It is possible to restore the natural color to the hair when premature graying appears, but only at its beginning. Therefore, if a person notices the appearance of the first gray hairs, he must consult a doctor, to diagnose the cause and prescribe the necessary treatment. Then it may become possible to restore the natural color to a certain percentage of the hair."
But according to her, most people ignore this condition at first and consult a doctor too late.
Crucial finding!
