As promised, in this article we have prepared information for you regarding the advantages and disadvantages of various modern screening programs, as well as the overall outlook on early diagnosis for significant reduction in mortality from oncological diseases.
What is screening, in general?
It is a healthcare organization strategy aimed solely at detecting or ruling out diseases in clinically asymptomatic individuals. Therefore, screening allows for the detection of diseases in their early, asymptomatic stages, when treatment is more effective.
On the webpage of HMZ Laboratories, a leading diagnostic center in India specializing in oncological diseases, the nature of these diseases is described in a simple and accessible manner: under normal circumstances, our body maintains a balance between cell growth and cell death, so when this balance is disrupted and cells grow uncontrollably, cancer develops.
In the Cancer Research UK blog, emphasis is placed on the benefits of early-stage cancer screening outweighing its harms. The same can be said for other technologies that provide us with increasing opportunities to detect any changes in our bodies. Of course, information is power, but it should be used in a way that prevents illness and does not worsen our mental and emotional state in the pursuit of health.
Modern medical capabilities allow for the identification of families with unfavorable genetic predispositions and immunological deficiencies, increasing the risk of developing malignant tumors. Such individuals are advised to avoid contact with carcinogens and adopt a healthy lifestyle.
Primary prevention of oncological diseases can reduce the likelihood of developing cancer by 70-90%!
Early diagnosis is crucial for oncological diseases. Secondary prevention of cancer involves medical measures aimed at diagnosing precancerous conditions and detecting cancer at early stages, ensuring the high effectiveness of both chemotherapy and surgical treatment of tumors.
Today, it can be asserted that cancer is no longer an incurable disease:
More than half of people diagnosed with cancer live for more than five years after diagnosis, and for some types of cancer and timely treatment, 80-95% of patients live for over 10-15 years.
Let's move directly to the advantages and disadvantages of cancer screening for various types.
Among the unquestionable benefits of this type of diagnostic approach is the ability to detect cancerous tumors before any symptoms appear, allowing for early treatment initiation aimed at alleviating patient conditions and reducing mortality rates. It's important to understand that cancer cells can grow and spread within the body before symptoms arise, complicating subsequent treatment strategies.
Disadvantages of screening examinations include complications during procedures (such as bleeding) and issues related to false positive and false negative test results. Additionally, it should be acknowledged that no diagnostic procedure can replace actual treatment, and the process of cancer detection itself may lead to psychosomatic disorders and reduce overall lifespan.
It's important to remember that when your doctor recommends a screening test, it doesn't always mean they suspect cancer. Screening tests typically do not diagnose cancer. If a screening test result is abnormal, further tests may be conducted to check for cancer according to established diagnostic protocols.
What you need to know before cancer screening?
Before undergoing a screening test, it's important to discuss all its details with your doctor or consider utilizing an existing service for a "second opinion." Every screening test can carry both benefits and risks. Your doctor is obligated to explain all nuances and guide you in deciding whether this screening test is suitable for you or not. This is called informed and shared decision-making. Only after understanding the pros and cons of the screening test should you make a decision on whether it's worth undergoing, based on what is best for you.
НFor example, a mammogram screening may detect breast density. However, this density could be either a malignant tumor or something else, requiring further diagnostic tests to clarify. Diagnostic tests may include a biopsy, where cells or tissues are removed for a pathologist to examine under a microscope for signs of cancer.
Therefore, screening is not the ultimate goal but rather one of the tools that should be used with benefit and awareness.
Until next time! Stay healthy!
