Cancer Diagnosis Checklist: How to Prevent the Disease
According to data of the World Health Organization as for 2018, every fifth man and every fifth woman in Russia is vulnerable to oncology diseases. Early diagnosis of cancer, which is being advanced by scientists throughout the world, can prolong human life and detect the disease at early stages.
Early detection of cancer
One of the most important steps of struggling against oncology diseases is the early diagnosis of cancer, as it helps to detect problems of the body at the early stages.
It is at the early stages that treatment is the most efficient for the patient. To detect predisposition to oncology diseases, track their start in time, and quickly prescribe required medicine, physicians use whole-body scanning and standalone tests.
To reveal a cancerous tumor in the human body, the following examination techniques are used:
- magnetic resonance tomography (MRT);
- computer tomography (CT);
- ultrasonography (US);
- multislice computed tomography (MSCT).
Besides, numerous laboratory tests of body fluids and special tumor marker tests are carried out.
Everyone who is attentive to health and wants to prevent the development of dangerous diseases can have a medical checkup. Modern scientists offer several ways that can help to detect the beginning of oncology diseases.
Comprehensive body checkup
Cancer cells are present in the body of every human, but antitumor immunity successfully handles them if the body is healthy. However, if a failure in tissue growth takes place, cancer cells may start multiplying and growing.
To detect the disease at the start, the World Health Organization recommends undergoing a medical checkup once per year. Such diagnosis is available in specialized clinics that have all the necessary equipment and conditions for making tests.
Modern private clinics offer a full package of services. Tests can take from several hours to a day. There are several checkup options:
- full body checkup;
- checkup of standalone systems (cardiovascular, respiratory, and others);
- cancer checkup (search for tumor markers);
- checkup for children.
There are such examination and risk detection programs for women and men and they are carried out taking account of age and individual features of the patient.
Preventive diagnosis of cancer is called screening. It allows examining a healthy-looking person and detecting cancer at the early stages. Such surveys are a complex of diagnostic maneuvers that reveal the slightest irregularities in the human body.
Surveys are recommended to people that stay in the risk group, for example, do unhealthy work, live in environmentally poor areas, have a genetic predisposition, etc. According to the statistics, early-stage cancer is recoverable or can be jugulated, so timely diagnosis can help to avoid a number of problems with health.
Cancer diagnosis in 10 minutes
One of the problems of quick cancer diagnosis is the fact that every type of oncology diseases is different, so it is necessary to search for them separately. However, Australian scientists state that they have solved this problem. They have developed a testing method that allows detecting any type of cancer using the blood test in 10 minutes.
Researchers of the University of Queensland have found a single signature for different cancer types and defined how to reveal it easily.
According to the description, the test detects nanostructure of oncology diseases using gold particles that change their color. This test cannot define the exact cancer type and its stage but it helps to avoid risks and quickly prescribe follow-up examinations. The method can be used as a tool of initial diagnosis – inexpensive, efficient, and rapid.
The standard way of detecting oncology diseases takes quite a lot of time: physicians have to find the location of the tumor, take samples from that place, and only then they can run tests. The minimally invasive method of Australian scientists should significantly simplify this process: when its efficiency is proven, the test will allow diagnosing cancer straight away, and then doctors will be able to proceed with looking for the tumor nidus and provide treatment to the patient.
When this testing method was verified using 200 DNA samples of cancer and healthy cells, the results showed 90% productivity.
Cancer diagnosis app
Scientists from different countries of the world are looking for new methods of cancer diagnosis. For instance, the Ukrainian cancer surgeon and IT specialist have developed Doctoright software that can diagnose cancer using international protocols.
Doctoright app is available free of charge and is compatible with any personal device or computer. The only thing the user has to do is to register. The program gives an independent assessment and makes a diagnosis basing on analyses. For example, the user can upload the X-ray image to the app and obtain the conclusion decision not influenced by the human factor. In case risks are detected, Doctoright offers the user to turn to the specialist to confirm or disprove the diagnosis.
Besides, the capabilities of the app include the telemedicine service. For example, if the patient, that lives far away from the district and regional hospitals, detects cancer symptoms, the app will advise contacting the specialist remotely.
The software allows the user to find a doctor, apply for a consultation, send medical records and test results, and then to get the conclusion decision. Doctoright also allows the patient to keep a health diary and rank survey findings according to their relevancy.
Cancer diagnosis is cheaper now
Cancer diagnosis methods are being advanced year by year, scientists are finding new ways of making surveys, and existing screening techniques are getting cheaper. For example, earlier molecular testing was very expensive – the sum reached $100,000 and a few people could afford such diagnostics. Today this procedure is not new and even middle-class people can make use of it. Today it costs from $700 to $1000.
Surveys in Russia
Besides, different early diagnosis methods are available to citizens of different countries as part of insurance and government programs. Almost all types of surveys in Russia are made as part of compulsory health insurance (CHI) and should be provided free of charge based on CHI certificate. Some of them are included in periodic health examination meaning that they are available free of charge even when the person has no symptoms and suspicions of cancer. Other surveys can be prescribed by the physician basing on the findings of the primary survey and medical necessity.
For example, free gastroscopy is carried out as part of the periodic health examination once per three years. Besides, citizens can do mammography and magnetic resonance imaging of the breast (for women), Pap test for cervical cancer, colonoscopy. However, people willing to take lung cancer screening tests have to do it for money.
According to recommendations of the World Health Organization, in order to control the health state and avoid risks of oncology diseases, patients should undergo basic examinations at least once per year. People staying in the risk zone need to undergo diagnostics more often, depending on personal predisposition and external factors.
Modern cancer detection methods allow running tests quickly and accurately. Thanks to this, physicians can start the treatment quickly and achieve better results.
