Onco Screening Or Early Diagnosis Of Tumors

Once screening or early diagnosis of tumors means a variety of examinations of the patient. A person can be formally healthy, and the tumor does not make itself felt at the beginning.

Who has an indication for cancer screening? Those patients who have:

  • Genetic predisposition to tumors. If mom, dad, brother, sister, grandparents, cousins ​​and cousins ​​have suffered from cancer, then it is likely that the disease will be diagnosed in the patient.
  • There are cysts and hemangiomas on the body or internal organs. In this case, talk about the risk of malignancy. This is the phenomenon when a benign tumor becomes malignant. This can happen with cysts, hemangiomas, osteomas and other similar tumors. That is why it is so important to diagnose tumors early. The earlier the cancer is detected, the more likely it is to get rid of it successfully.
  • The man reached 35 years of age. According to statistics, it is people aged 35 and over who most often suffer from cancer.
  • Presence of bad habits, wrong way of life, bad food, ecology. The more factors a particular person has, the more prone they are to cancer. At least, experts say so. According to statistics, every third smoker sooner or later develops tumors in the lungs or bronchi, trachea.
  • A large number of stressful situations. Doctors have long proven that stress provokes the development of cancer.
  • Even if the patient is not in any of the risk groups, he can undergo cancer screening prescribed by a doctor, after prior consultation.

Cancer in the early stages is asymptomatic. Sometimes there is weight loss or constant nausea and vomiting. But to determine whether there is a tumor in the body, you can only with the help of cancer screening or early diagnosis. No other research methods will provide a complete picture of the situation.

Today oncostring is carried out with the help of modern high-tech equipment. The procedure does not take much time, which is convenient for the doctor and, of course, the patient.

How often should you be screened for cancer? Provided that the person is not worried about anything, it is enough to conduct research at least once a year. If cancer is suspected, it is not necessary to make a self-diagnosis, it would be correct to see a doctor and get the best CT scan in Delhi as soon as possible.

Breast cancer is the most common type of cancer among women around the world. In the early stages, breast cancer may not cause pain or other symptoms. At the same time, the detection of this type of cancer at an early stage is the key to successful treatment.

Every woman after the age of 20 should have self-examinations once a month (on days 10-12 of the menstrual cycle), as well as be examined by a mammologist once a year.

The main methods of diagnosing breast cancer:

  • Examination by an oncologist surgeon;
  • Ultrasound of the mammary glands and regional lymph nodes (for women under 40)

If a tumor is detected, a biopsy is performed (needle needle or trepan biopsy). If there is evidence of a tumor process, mandatory (chest X-ray, abdominal ultrasound) or additional (computed tomography, magnetic resonance imaging, radioisotope examination, etc.) methods of examination are prescribed. For knowing ultrasound scan cost, contact your consulted doctor as soon as possible.

For further treatment planning, laboratory tests (general analysis of blood, urine, blood type, etc.) are performed.

Alzheimer's Diagnosis, What Are The Differences Between A Resonance, A CT Scan And A Cerebral PET?

Magnetic resonance imaging, Computed Axial Tomography (CT) or Positron Emission Tomography (PET) are three neuroimaging tests that allow us to obtain 3D brain images and high resolution. Neurologists can request them to confirm a diagnosis of Alzheimer's disease and rule out other causes that may be behind cognitive disorders such as memory loss.


When we talk about these tests, the image that comes to mind is that of diagnostic testing which we have to be completely still, lying down and with our heads inside a donut-shaped device. Although the machine and a part of the procedure are similar, the three tests are different and offer us different information.

Here are the most significant differences between them:

Magnetic resonance

It works with a magnet. To get an idea of ​​its power, a 3 Tesla magnetic resonance is equipped with a magnetic field 60,000 times more powerful than Earth's. This magnetic field is combined with radio pulses to detect the magnetic characteristics of the body's hydrogen atoms, and thus be able to send the computer the information necessary to reproduce the brain image.

Provides comprehensive information of soft tissues. It is one of the most used techniques in research since it allows to obtain high-resolution images, with detail of up to 0.4 millimeters, in the case for example, of resonance of 3 Teslas.

It is harmless, does not produce ionizing radiation. Therefore, and due to the magnetic field, it is only contraindicated in people who have a pacemaker or metal implants.

The test usually lasts more than 30 minutes. The person inside the machine must be still during the entire acquisition.

It is a very noisy test. The sound comes from the vibration of the gradient coils, produced by the alternative passage of the current needed to scan.


It works with an x-ray beam. The scanner allows obtaining multiple images, taken from different angles, from the absorption made by the different tissues to X-rays.

It offers bone, soft tissue, and air images. Its resolution in soft tissues is lower than that of magnetic resonance.

It emits small ionizing radiation. The risk of developing cancer due to radiation is negligible. However, it is not recommended to repeat the test excessively and its use is only prescribed in children when it is strictly necessary. Nor is it recommended for pregnant women, because of the risk that it may affect the foetus.

Some tests can be done in just 10 minutes. The person inside the machine must also be still during the entire acquisition. It is suggested to know the CT scan price in Delhi first, before having a CT scan.

Brain PET

It works with a radioactive tracer that is administered intravenously before testing. To take the images, the PET machine also incorporates a CT scan or an MRI.

Provides information about biological processes. Thanks to the contrast substances contained in the tracer, it allows obtaining high definition images to assess aspects such as, for example, the consumption of glucose in the brain, which indicates the activity of different areas or to detect the characteristic amyloid protein deposits of Alzheimer's disease.

It also uses ionizing radiation. Therefore, the best CT scan in Delhi is not recommended for pregnant women.

Computed Tomography: What Is Important To Know?

Computed tomography is a non-invasive x-ray diagnostic method that can serve as the basis or an additional source of information when making the correct diagnosis and prescribing the necessary treatment.


Is computed tomography safe?

Yes, CT is considered a safe method. X-ray dose is relatively low. There is a small risk in the presence of concomitant pathology of the kidneys, thyroid gland, bronchial asthma, if the use of contrast agents is used. It is good to know the CT scan price in Delhi before undergoing one.

The patient should warn the doctor if he is allergic to drugs, iodine, seafood, if he suffers from diabetes, bronchial asthma and thyroid diseases and about the drugs that he takes.

During pregnancy, the question of conducting a CT scan is decided by the attending physician; a woman must inform about the presence and timing of pregnancy!

Information for patients:

  1. As a rule, computed tomography is performed without preliminary preparation.
  2. With the use of intravenous contrast agent on an empty stomach.
  3. In chronic diseases of the liver and kidneys without exacerbation, moderate fluid intake is recommended 6 hours before the study.
  4. The study time is 15-25 minutes; scanning itself from 4 to 20 seconds.
  5. During the scan, you need a stationary body position on the table and the ability to carry out breath holding commands for 4-20 seconds.
  6. Before the study, clothing with metal hooks, buttons and zippers should be removed; jewellery in the form of chains and earrings.
  7. With the introduction of a contrast medium, the patient may feel a passing wave of heat.

To undergo research in the CT-MRI department, you should have:

The passport- A referral for the best CT scan in Delhi from a doctor, which indicates:

  1. Name
  2. No. of medical history or outpatient card
  3. The diagnosis
  4. The field of study with the formulation of a specific task (identification, exclusion or confirmation of the presence of changes on the part of the examined organs and systems)
  5. A note on the absence of contraindications for intravenous administration of a contrast medium (if the study is conducted with contrasting). When recording a patient, he is informed of the time of arrival at the department (and not the time of the start of the study)

Relative contraindications to the administration of contrast medium:

  • Pregnancy
  • Allergy to iodine-containing contrast agents
  • Severe hepatic and renal failure
  • Decompensated diabetes mellitus
  • Myeloma
  • Decompensated thyroid disease

Recommendations after computed tomography using a contrast agent:

* It is very rare for patients to have a rash on their skin, etc. - side effect of injection of iodine solution. Therefore, the outpatient should be under the supervision of a doctor in the CT-MRI unit for 2 hours, so that in case of a skin reaction he can receive timely medical help.

* If you have been given a contrast drug intravenously, it is recommended that you drink clean water within the amount allowed by your doctor for a day (1-3 l) in order to speed up the removal of the contrast drug from the body.
