Inca alerts the population to the risks of bowel cancer; see symptoms – 11/25/2021

On the occasion of the date that marks the National Day to Combat Cancer, November 27, the Inca (National Cancer Institute) launches a campaign alerting society to the risks of the disease when it affects the intestines.

The initiative, with the theme of Bowel Cancer: What Do You Need to Know?”, will be developed by Inca at the end of this year and throughout the next, with clarification material, publicity pieces and events.

The campaign was launched this Thursday (25) with a seminar broadcast by Inca’s YouTube channel. The lectures were recorded and are available for those who want to know more about the topic.

According to the institute, 30% of new cases of bowel cancer can be associated with poor diet, overweight, physical inactivity and excessive alcohol consumption. Therefore, prevention plays an important role in the face of the increase in overweight and obesity in the country.

Between 2003 and 2019, the number of obese people aged 20 or over increased from 12.2% to 26.8%, more than doubled in less than 20 years. Obesity affects one in four people over 18 years of age. Data are from the 2019 National Health Survey.

The National Cancer Institute emphasizes that the disease is treatable. Therefore, early diagnosis is essential for the treatment of bowel cancer to be effective. One of the challenges is to make the population more aware of the disease, identifying symptoms and aspects of this type of cancer.


In the virtual seminar, the head of the Surveillance and Situation Analysis Division of the Inca Prevention and Surveillance Coordination, Marianna Cancela, presented the situation of bowel cancer, the third most common neoplasm among Brazilians.

The estimated mortality of people over 15 years of age from the disease is 160,000 between 2026 and 2030, with 82,400 among women and 79,400 among men.

In comparison with the beginning of the 2000s (2001 to 2005), the figures projected for the end of this decade can mean a threefold increase, in the case of men, and 2.6 times, in the case of women. “Approximately 6 million years of life will be lost between 2021 and 2030,” lamented Masrianna Cancela.

Currently, among men, the most common manifestation of cancer is prostate cancer, with 29.2% of cases. Among women, the most frequent type of cancer is breast cancer, with 29.7% of records.


The main symptoms of bowel cancer are blood in the stool, diarrhea, constipation, stomach pain, weakness, anemia, weight loss for no apparent reason, thin and long stools, and swelling in the abdomen.
