Examining for cancer or irregular cells that might lead to cancer in the body of people that have no symptoms is known as screening.
Screening can help medical practitioners to detect and treat different kinds of cancer on time before they start surfacing. Early discovery is crucial because when abnormal cancer or tissue is found on time, it may be a lot easy to treat. By the time the symptoms surface, the sickness might have started to spread in your system and might be difficult to treat.
A lot of screening tests has shown to detect cancer before time and minimize the possibility of deaths from the sickness. However, it is essential to know that a screening test might have benefits, as well as potential harms.
Some cancer screening (ตรวจคัดกรองมะเร็ง, which is the term in Thai) tests might result in bleeding and some health issues
- A screening test might have a “false-positive” result. That is to say; the test reads that cancer might be in your body, although it is not. A false-positive test result may cause worries and is followed by additional procedures and tests that also have possible harms
- A Screening test might have a “false-negative” result. That is to say, the test reads that there is no cancer in your body, but there is. A false-negative test result can provide a false assurance, resulting in delays and perhaps, making an individual disregard seeking medical attention even when the symptoms starts developing
- Screening might result in overdiagnosis. That is to say; the test shows correctly that an individual has cancer, but it is growing slowly and might not harm the person throughout his or her lifetime. Treating such cancers is known as overtreatment.
It could be more helpful for individuals to talk about the possible harms as well as the advantages of running a screening test for cancer with their doctors.
