What causes cancer? There is no easy answer to this question. People leading a healthy lifestyle may get cancer while others with an unhealthy diet, smoking habit and other possible causes of cancer constantly present in their lives, may live long and happily. Cancer cause is sometimes thought to mean a ‘direct cause of cancer’. It is true to some extent for specific cancer causes but for many others, they only slightly increase the danger.

Does it mean that we should not care whether our habits and environment become a potential cause of cancer? Nothing more wrong. Having in mind that these are possible causes of cancer, we should at least try to make our lives healthier and to get bigger prospects of decades of happiness with our family and friends.

cancer causes
Smoking can causes lung cancer, esophagus cancer, mouth cancer, throat cancer or other cancer types.

Cigarettes is one of the most popular cancer causes

Cigarettes and other tobacco products are often held accountable as an important cause of cancer. But is that so? Unfortunately, yes, both smoking and being a second-hand smoker is the cause of lung cancer as well as throat, stomach, kidney and many different types of cancer. Tobacco was not known as a cancer cause for many years due to the lobbying of corporations but nowadays every now and then a new study appears, showing it as a direct cause of cancer. For this reason, stop smoking or never start if you have such a chance.

Genetics Play a Big Role

The development of science brought another saddening news – genetics is the cause of cancer. Moreover, some scientists claim that genetics is the primary, direct cause of cancer in many types of diseases, such as breast cancer. Women with breast cancer history running in the family are advised to visit their doctors regularly in order to spot the disease in its early stages.

Neglecting the genetic cause of cancer may be a major mistake costing health or even life. If you have a history of cancer in your family, you should be aware that your own genetic code may be a possible cause of cancer in the future.

Radiation

Various types of radiation were proven to be cancer causes. To the most obvious types of cancer-inducing radiation belongs radiation from radioactive materials – it was a direct cause of cancer for many people affected by Chernobyl and atomic bombings during the II World War. However, this is not the only type of radiation counted among possible causes of cancer. Medical devices such as CAT scan also emit radiation which in bigger doses could become a cancer cause. For this reason, the area where X-ray operates is not easily accessible and patients are dissuaded from undergoing such treatments often.

Finally, radiation from the sun or so-called UV radiation is the direct cause of cancer of the skin. According to scientists, we shall abstain from long sunbathing in the middle of the day and apply sunscreen in order to get a healthy tan, not a skin cancer.

Infections

Some infections are also known as cancer causes. Especially one virus, HPV, is known to be the direct cause of cancers of cervix, vagina, vulva, anus, penis, and throat. Additionally, HPV may be a leading cause of mouth cancer, though this link needs to be studied more extensively.

Yet another virus, the Epstein-Barr virus (EBV), while not a direct cause of cancer, may be among lymphoma and nasopharyngeal cancer causes.

Finally, HBV and HCV liver viruses may lead to chronic liver disease and dysfunctions which in turn are often counted as possible causes of cancer of the liver.

Research has shown that some types of cancer are more common in people who are overweight or obese.

Obesity and the Lack of Physical Activity

We know that lack of movement and obesity cause troubles but I’m pretty sure most of the people would count obesity among possible causes of cancer. Still, here it is. Nowadays we know that obesity is among key cancer causes in diseases such as bowel cancer, womb cancer, breast cancer, and many others. While it isn’t called a direct cause of cancer, obesity significantly increases the risk of carcinogenic tissue’s appearance in your body. For this reason, fighting obesity can be held equal to fighting the possible causes of cancer. Stay fit!

Unhealthy Diet

Similarly, using cooking oil multiple times without changing it leads to the creation of trans fats – digesting them is the cause of cancer of the colon and other types of cancer.

If you have a possibility, change your unhealthy diet soon. You will not only get more energetic but also cross out yet another one of possible causes of cancer.
