Colon cancer – causes, symptoms, and treatment gas efficient cars under 5000


Note: the aggravating aspect of meat and fat consumption has only been observed in a few studies. They note that people who eat an average of 160 g of red meat, offal and/or deli every day are three times more likely to develop colorectal cancer than those who consume 80 g per week. Alcohol and smoking

• The alcohol, which is a major risk factor for colon cancer when consumed at a rate of more than 1 drink per day or more than 7 drinks per week. It should be noted in parallel that the risk increases with the amount of alcohol consumed and not the type of alcohol.

• The tobacco, which is also a risk factor since it is found that smoking significantly and for a long time increases to 3 times the risk of developing colorectal adenomas, themselves often linked to colorectal cancer. It is, moreover, one of the main causes of lung cancer.

In addition, it is important to fight overweight, including regular physical activity, about half an hour a day. Indeed, physical inactivity is a significant risk factor that has been clearly established. As a result, more colorectal cancers are found in people who are overweight or obese. Causes of colon cancer: medical history

It is not always easy to diagnose colon cancer because its symptoms are not obvious. Fortunately, organized screening is gradually taking place. Vigilance remains the best weapon to fight against this type of cancer and to change statistics. Colon cancer: few symptoms

The symptoms found can also be caused by many other conditions and are not always synonymous with cancer, such as in case of disorders digestion. In addition, the symptoms will vary depending on the location of the tumor. It is their sudden onset or persistent character that should alert patients.

Indeed, colorectal polyps and colon tumors have blood vessels that can release a small amount of blood into the stool. Generally, this blood is not visible to the naked eye and only examinations performed in order to detect a colon cancer (Hemoccult test) can detect it.

When symptoms, even those not specific to colorectal cancer, worsen, see your doctor or even an emergency department becomes essential. It is the exacerbation of even classic symptoms that is then a symptom of colon cancer. Indeed, by magnifying, the tumors of the colon will lead to more and more marked symptoms such as:

• Similarly, as organized screening is relatively recent, it has not yet been able to have a significant impact on the evolution of mortality rates (the participation rate in the national screening program remains below the European recommendations of 45% minimum since it is only 33.5% over the period 2016/2017).

Good to know: in 2011, there were 9,200 deaths of men (more than 24,000 in 2017 in Europe) and 8,300 deaths of women (21,000 in 2017 in Europe) following a cancer of the colon; this rate tends to decrease more rapidly in women than in men. Stages of colon cancer

Based on these criteria, it is possible to establish the stage of colon cancer and thus to characterize it accurately. These elements are summarized by the international TNM classification: tumor, lymph nodes (“nodes” in English) and metastases.

• Finally, there is the case where the tumor cells have crossed several layers of the wall of the colon or rectum. Then It is stage II with T3 if the tumor invades the subserosa which lies between the muscular and the tissue surrounding the colon or rectum.

When colon cancer spreads, it spreads its cancer cells to neighboring lymph nodes (they are mostly in the fat mass that surrounds the large intestine). The only way to know if the lymph nodes are affected is to perform a biopsy and study them under the microscope. This step corresponds to that of the diagnosis.

The main goal of radiotherapy is to prevent local recurrence of colon cancer. However, recurrences appear mainly in other parts of the body, in other organs and not locally. Thus, radiotherapy is not particularly indicated for treating colon cancer.

However, radiotherapy remains used to eliminate isolated metastases or relieve certain symptoms when the tumor could not be removed. In addition, it is suitable for the treatment of rectal cancer since recurrences are more likely to occur in the same region.
