Colon and rectum cancer: sedentary lifestyle and diet rich in red meat may increase risk

Colon and rectum cancer: sedentary lifestyle and diet rich in red meat may increase risk

The large intestine (colon) is the portion of the digestive tract where stool is formed, and the rectum, where it is stored before evacuation. In Brazil, except for skin cancers, colon and rectum cancer is the second most frequent in the female population, and the third in men, according to data from the National Cancer Institute (INCA). The likelihood of developing colorectal cancer over a lifetime is 5%. The number of new cases has been falling in more developed countries, such as the United States, probably due to effective screening programs. In Brazil, there is an increase in the incidence of bowel cancer. Risk factors include genetic predisposition, excessive alcohol consumption, inflammatory bowel disease, radiation, age over 50, type 2 diabetes, obesity, smoking, and diet. Modern life has given us the chance to live longer, which has raised the incidence of cancer. In addition, we are increasingly sedentary, overweight and eat less natural foods, such as vegetables, fruits and grains (cereals).

Some of these risk factors are watertight, such as old age, genetic predisposition, diabetes, disease inflammation and radiation. However, there are two primary conditions that can be interfered with in order to prevent colorectal cancer:

Lifestyle changes:

  • No smoking
  • Do not overuse alcohol
  • Reduce meat consumption red and processed meats, especially the barbecue
  • Eating more fruits, vegetables and grains
  • Practice physical activities at least three times a week
  • Losing weight, especially abdominal fat

Methods and exams for early diagnosis, which should not be done in the general population from the age of 50:

  • Fecal Occult Blood Testing: Annually. This is a simple fecal examination. It is a method with high false-positive and false-negative rates. If so, colonoscopy should be performed. Colonoscopy is increasingly used only because it needs to be done every five years, and it detects changes so early that they would not even result in a positive finding of fecal occult blood
  • Colonoscopy: Every 5 years. This is an endoscopy of the colon and rectum performed under sedation, after a preparation of the colon with laxatives. This test is largely responsible for the drop in colorectal cancer incidence and mortality rates in countries with serious screening programs. This is because it is through him that the polyps are removed, small benign tumors from where the cancer originates. In addition, when cancer is detected early, the chance of cure is very high. It is a safe examination, provided it is performed in clinics with adequate structure and experienced and well-qualified professionals.

Individuals with a family history of colorectal cancer and / or polyps and inflammatory bowel disease should inform their physician to enter special prevention intervals

Conclusion:

Therefore, with lifestyle modifications and participating in colonoscopy prevention programs, the chance of having bowel cancer will certainly be drastically reduced.


Painless adhesive promises to replace injection needles and vaccines

Painless adhesive promises to replace injection needles and vaccines

For those who suffer from the fear of needles, being vaccinated or taking an injection is almost a nightmare. However, each day we approach a scenario where the needles no longer have. A creation of American researchers at the National Institute of Health and together with the Georgia Institute of Technology promises to make a lot of people celebrate: a simple adhesive, easy to use and as efficient as a needle (but without the pain and discomfort) .
