Skin Cancer – Causes and Risk Factors

Causes of Skin Cancers

The most common cause of skin cancers are ultraviolet (UV) rays, either from the sun, or from UV-emitting lamps, like those in tanning saloons. Both UV-A and UV-B rays may cause skin cancer.

Other possible causes of skin cancers include:

  • A high dose or repeated X-ray exposure (1,2)
  • Exposure to arsenic (pesticides, wood preservatives, miners, sheep shearers, farmers) (1), pitch (from distillation of wood or coal tar), creosote, or radium (5)
  • Therapy that destroys immune cells – chemotherapy, radiotherapy, immunosuppression in organ or bone marrow transplantation (2)
  • Smoking – increases risk of squamous cell carcinoma (4)

Risk Factors for Developing a Skin Cancer

The possibility of developing a skin cancer increases with the following factors:

  • People with fair skin, freckles, blond or red hair, blue or green eyes are at most risk to develop skin cancer (2).
  • Skin disorders with lack of skin pigment melanin (albinism, xeroderma pigmentosum) (2)
  • Tanning poorly (1)
  • Several, unusual or big moles at birth (2)
  • New or changing mole (5)
  • Close relatives with skin cancer (2)
  • Previous skin cancer (2)
  • Severe sunburn, especially early in life (2)
  • Scars (2)
  • Actinic keratosis (1)
  • HIV infection – increases risk of Kaposis’s sarkoma (3)
  • A constant exposure to the UV rays: a high altitude, regions close to equator and regions with impaired ozone layer in atmosphere (Australia) (1)
  • Repeated sun exposure (outdoor workers, sailors, farmers, drivers) (1)
  • White race, men, age after 50 (6)

    Gasoline, Petroleum and the plastics made from it are the single largest cause of cancer in the world. This is a known fact, verified by thousands of studies which the oil industry counters by paying pundits to say: “Well, we just are not sure yet”. Now we are sure. The TPH array in petroleum and petroleum products exists as microscopic particles which leach off of plastic materials, (ie: the plastic in water and baby bottles) and float in the air as vapor, (ie: the fumes around gas stations). These particles are absorbed into the body and broken down to a cellular level and then to a DNA level. As the DNA replicates, a constant process, these TPH materials cause the replication process to make mistakes and create genetic mutations. TPH is a very particular array of items so the “mistakes” that it causes occur as the same thing over and over. We call this repeating mistake: “cancer”. Other materials in our environment cause other kinds of genetic mutations that do not manifest as onerous, or extremely negative, or obvious things. TPH manifests cancer.

    The TPH chemical array has killed more Americans than every terrorist since the beginning of time.

    The petrochemical bisphenol-a, or BPA, causes precancerous tumors and urinary tract problems and made babies reach puberty early.

    Every gas pump has a label on it that oil and gas causes cancer and a host of lethal medical problems.

    Archeologicial digs show that ancient peoples living near tar pits got cancer.

    When there is an oil spill, you are not allowed on the beach because most agencies classify oil as toxic.

    A study of childhook leukemia in England mapped every child with the diserase and found they all occurred in a circle, in the center of which was a gas station.
    Living near a petrol station could quadruple the risk of childhood leukaemia, research suggested today.
    The study in France found a link between cases of acute leukaemia among youngsters and how close they lived to a fuel station or a repair garage.
    Research has already shown an association between adults’ occupational exposure to benzene, a hydrocarbon derived from petrol, and leukaemia.
    The latest study is published in the journal Occupational and Environmental Medicine. The French Institute of Health and Medical Research based their findings on 280 cases of childhood leukaemia and a comparison group of 285 children.
    They were drawn from four hospitals in Nancy, Lille, Lyon and Paris, with almost two-thirds of the children with leukaemia aged between two and six.
    The team found no clear link between the mother’s occupation during pregnancy or traffic levels around where they lived and the risk of child leukaemia.
    They also saw no link between leukaemia and living near manufacturers using materials such as aluminium or plastic.
    But a child whose home was near a garage was four times more likely to develop leukaemia than a child whose home was not.
    The risk appeared to be even greater for acute nonlymphoblastic leukaemia, which was seven times more common among children living close to a petrol station or garage. The longer a child had lived there, the higher their risk of leukaemia appeared to be.
    There are 6,600 cases of leukaemia a year in Britain. Although it is the most common form of childhood cancer, it affects three times as many adults as children.
    The authors admit the findings could be due to chance. “But the strength of the association and the duration of the trend are arguments for a causal association.”

    Alberta’s oil sands are one of the world’s biggest deposits of oil, but the cost of extracting that oil may be the health of the people living around them. High levels of toxic chemicals and carcinogens have been found in the water, soil, and fish downstream of the oil sands. The local health authority of Fort Chipewyan, Alberta comissioned the study in response to locals’ claims that the oil extraction projects upstream were damaging the health of citizens. Petrochemicals and their byproducts, such as dioxin, are known to cause an array of serious health problems, including cancers and endocrine disruption.Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil. Crude oil is used to make petroleum products, which can contaminate the environment. Because there are so many different chemicals in crude oil and in other petroleum products, it is not practical to measure each one separately. However, it is useful to measure the total amount of TPH at a site.TPH is a mixture of chemicals, but they are all made mainly from hydrogen and carbon, called hydrocarbons. Scientists divide TPH into groups of petroleum hydrocarbons that act alike in soil or water. These groups are called petroleum hydrocarbon fractions. Each fraction contains many individual chemicals.

    Some chemicals that may be found in TPH are hexane, jet fuels, mineral oils, benzene, toluene, xylenes, naphthalene, and fluorene, as well as other petroleum products and gasoline components. However, it is likely that samples of TPH will contain only some, or a mixture, of these chemicals. The International Agency for Research on Cancer (IARC) has determined that one TPH compound (benzene) is carcinogenic to humans. IARC has determined that other TPH compounds (benzo[a]pyrene and gasoline) are carcinogenic to humans.

    Benzene causes leukemia. Benzene as a cause of leukemia had documented since 1928 (1 p. 7-9). In 1948, the American Petroleum Institute officially reported a link between this solvent used in many of their industries used and cases of leukemia in their workers. Their findings concluded that the only safe level of benzene exposure is no exposure at all (2).

    The largest breast cancer incidents are in Marin County, California which is tied to the air, water and ecosphere of the Chevron Oil refinery right next door.

    The oil industries spend tens of millions of dollars on fake pundits and disinformation to make sure the above information is never known by the public. Cure Cancer: Stop oil. It is a national security need in more ways than one.
