Today, cancer affects approximately 433,000 people.
Although the disease is quite common, it is nevertheless possible, in almost half of the cases, to modify some lifestyle habits to prevent it. Explanations.
Prostate, breast and lung: the most common cancers
Cancer is a disease that results from an anarchic multiplication of certain cells in the body. These proliferate locally at first before spreading to the surrounding tissue and then further away where they form metastases.
There are different types of cancer. Thus, we call “ cancer in situ » early stage cancer, when it is confined to the immediate area. It has not started to invade adjacent tissues.
We then call infiltrating cancer or invasive cancer a cancer whose cells have invaded the tissues surrounding the tumor.
“The term “cancer” covers different realities by bringing together a very heterogeneous set of diseases, both from the point of view of their natural history as well as risk factors, diagnostic and therapeutic conditions as well as prognosis” indicates Public Health France.
Today, the total number of new cancer cases is estimated at 433,000, 57% of them among men. This number has doubled since 1990.
According to the National Cancer Institute, “prostate, breast, colon-rectum and lung cancers are the most common cancers in France”.
The majority of them can be detected fairly early and treated, giving patients a better chance of recovery.
In humans, le cancer from the prostate is the most common, followed by lung and colorectal cancers. In women, breast cancer remains the most common, followed by cancer colorectal and the lung.
Cancers that could be avoided
According to Public Health France, “a certain number of cancers could be avoided”.
Thus, in 2015, almost half of cancers in those over 30 were the consequence of modifiable risk factors such as tabagism, alcohol consumption, diet, excess weight and certain infectious agents.
Exposure to natural and artificial ultraviolet rays as well as certain occupational exposures were also involved.
In humans, the main causes of cancer are tobacco and alcohol followed by diet. In women, the main causes are also tobacco and alcohol, followed by overweight and obesity.
