Prevention: one in three cancer cases can be avoided 

Cancer is one of the diseases that most frightens and terrifies people. It can be caused by several factors which if combined together lead to its onset. As long as it is benign, and therefore has not metastasized, it can be removed by surgery and therefore cured, but if it gave rise to metastasis then it becomes very dangerous and unfortunately in most cases fatal. The researchers have ascertained that through the prevention and a healthy life the appearance of about one in three cancer cases can be avoided
First of all, smoking is the main culprit for lung cancer cases and beyond, beyond what one might think, the habit of smoking not only damages the respiratory system, but also affects other organs, increasing the risk of incidence of cancer of the mouth, bladder and stomach. Obesity is another risk factor that is not only dangerous for the cardiovascular system increases susceptibility to mutations of tumor suppressor genes and proto-oncogenes leading to cancer. 
Obesity, smoking are therefore factors that favor the onset of malignancies, and therefore are part of the cancer prevention program and should be avoided. A sore point, however, also affects many foods , which due to some of their characteristics and their nutritional content increase the incidence of cancer. First of all all foods that have a high protein content, such as meat and egg, they must be consumed without excess, and above all avoid eating them for two or three consecutive days; the ideal would be to alternate meat and fish so that our body does not accumulate an excess of protein. As well as meat, even foods with high caloric content must be avoided, and therefore the consumption of sweets, too sugary drinks and fast food foods must be limited because they are too fat.

Water is the drink to be preferred to all others, and because as I said before you have to avoid sugary drinks too, and is also why alcohol is bad and brings damage to our cells. Prevention does not ensure that we are immune to this disease because in addition to external factors it is also caused by genetic factors , but abuse of high-calorie foods, smoking or consuming too much red meat increase the incidence risk of an invaluable value, and researchers therefore advise avoiding them to spend a more peaceful life.
