5 surprising causes of cancer

It is well known that lifestyle can play an important role in cancer development. Smoking and excessive sun exposure are just some of the possible triggers of this disease serious enough.
These are not the only things that can exhibit a higher risk of cancer. Here are five reasons surprising encountered in everyday life, which you probably do not know that could trigger cancer.

Items that did not know it could trigger cancer
Alcohol. The researchers found that alcohol is a carcinogen, even when consumed in moderation. According to recent studies, the average consumption of alcohol was associated with approximately 30% of all deaths due to cancer. The strong link between alcohol and cancer deaths were seen in breast cancer, esophageal, colorectal and liver.

Grilled meat and fish: risk of prostate cancer and colorectal cancer. Beef, pork, fish or poultry, cooked at high temperatures (fried or grilled) can form chemicals called heterocyclic amines and polycyclic aromatic hydrocarbons when in contact with open flame. In a recent study, researchers found that increased intake of grilled meat (especially red meat) increases risk of colorectal adenoma, a precursor of colorectal cancer.

Sunscreen. Everyone knows that ultraviolet radiation can cause skin cancer. Know, but as sunscreen creams may increase the risk of skin cancer?
A recent study found that when exposed to sunlight, zinc oxide – an ingredient found in many sunscreen – undergoes a chemical reaction which could release unstable molecules known as free radicals. These molecules can damage DNA molecules, raising the likelihood of triggering cancer. However, research is in early stages and scientists do not recommend quitting sunscreen when in the sun.

The Night. Besides the fact that working at night unbalanced sleep schedule, it may also increase the risk of women getting breast cancer.
Interruption of work during the night circadian cycle – a trigger of several types of cancer. Studies have shown that women who worked as nurses or flight attendants (night shifts) had a significantly higher risk of formation of breast cancer as women who worked only during the day. One possible reason is disrupting circadian system caused by exposure to light at night. This can suppress melatonin production and may promote the action of genes involved in tumor development.

Exhaust emissions of diesel engines operating. Recently, researchers have begun classifying emissions of diesel engines as carcinogen, based on sufficient evidence. Scientists have discovered an increase in the rate of death from lung cancer among those exposed to the gas emissions of diesel engines. Experts say that the number of lung cancer deaths has tripled among those who have spent much time breathing polluted air emissions such.
