He Working Group on Preventive Services From the United States, a non -governmental organization of American doctors, highlighted the existence of early detection of four types of cancers: of lung, breast, colorectal and cervix. This group of experts said that the newspaper can save lives without exposing people to false alarms, additional evidence or unnecessary treatments.
The specialists affirmed that the screening helps to find some malignant tumors months, or even years, before a person feels bad enough and must go to the doctor. “The screening is in the front line to reduce cancer deaths,” he said Robert Smithepidemiologist of the American Society against Cancer To The New York Times and clarified: “In addition to detecting cancer early, the screening of colorectal cancer and cerretine can also help prevent diseases.”
“From time to time, the group of experts systematically reviews the evidence that supports cancer screening and issues recommendations by age and possible risk factors,” he said John WongVice President of the Working Group on Preventive Services. Performing with periodicity the screenings reduce deaths from the most frequent types of cancer. An organization analysis shows 13 percent less deaths from lung cancer and 30 percent less breast cancer deaths. The results also show that the screening reduces the deaths from colorectal cancer by 85 percent and 80 percent of cervical cancer deaths.
“But to obtain all these benefits, patients should undergo tests regularly. It is very important that the frequency of screening coincides with the increase in risk over time,” he warned Mary Reid, epidemiologist of Roswell Park Integral Oncological Center. According to Reid, the indicators are as follows:
Lung cancer: Every person between 50 and 80 years with significant history of smoking should undergo a computerized dose computed tomography. Breast cancer: women from 40 to 74 years should be done periodic mammograms. Colorectal cancer: people from 45 to 75 must undergo a colonoscopy or feces at home. Cervical cancer: women between 21 and 65 should undergo a routine cancer screening with a vaginal cytology or a human papillomavirus test.
For some types of cancer, such as leather, mouth and bladder, there are no periodic and preventive tests to recommend. In other cases, such as ovarian cancers, pancreas, testicles and thyroid, it has been discovered that the screening of people without symptoms can lead to too many false positives and complications without reducing the risk of death.
“Sometimes, the treatment is worse than having cancer,” Reid warned and concluded: “Most prostate cancers grow so slowly that they would never be a problem. Although screening can detect these malignant tumors, you run the risk of a cascade of unnecessary treatments and its consequences can generate rectal hemorrhages and helplessness.”
