Cancer screening

Cancer screening means the detection of traced elements of cancer in body. We are made to live in permeated climate now-a-days that leaves us with the throng of fierce killer disease. People take the expenses and strains of test in order to sustain without fear, Cancer screening test are conducted to find out traces of cancer elements prior to arrival of signs and symptoms. These types of tests help to serve dual purposes:

  • Making an effective reduction in the number of people who are likely to develop the disease
  • Prevention of death from cancer


Cervical cancer test

When a patient is suspected to have cervical cancer, the doctor commences the treatment with thorough examination of the cervix. Colposcope – a magnifying instrument is used to check the trace of abnormal cells.

While conducting the colposcopic examination, the doctor might take samples of cervical cells for lab testing. The Cervical cancer test comprises a combination of the following:

  • Punch Bioscopy: This involves usage of a sharp tool by which small samples of cervical tissues are pinched off
  • Endocervical curettage: This involves using a curet. A curet is a spoon-shaped instrument used in scraping of a tissue sample from the cervix,

The doctor might opt for some other more dignified methods for the testing, if the above are proven critical:

  • Electrical Wire Loop: This test uses a thin, low-voltage electrified wire for getting smaller tissue as sample. This test requires application of anaesthesia
  • Cone Biopsy: This includes the procedure where a doctor is allowed to get deeper layers of cervical cells for lab processing. General anaesthetic methods are deployed in order to make successful carrying of the procedure.

Cervical cancer Screening

In cervical cancer, tumours are seen to grow in the cervical position that includes shoulder and places around the cervices.

The Cervical cancer Screening comprises of the following:

  1. Human papillomavirus testing: In this test, cells are worn out from the outer part of the cervix of a woman. These are then tested for particular kinds if strain of HPV. There are some HPV strains which are more prone to give out cervical cancer. This type of test is conducted along with a Pap test. This test might also be done on samples of cells that are collected from vagina of a woman. She herself is able to collect those.
  2. Pap test: Cells from outer part of cervix is also utilized in conducting of this test. A pathologist can then identify the existence of any precancerous or cancerous cells in the cervix.


Breast cancer screening

Doctors may order a number of tests to look for and diagnose breast cancer. Among the various methods applied so far, Mammography is the most relevant which is found appropriate for most of the victims.

Digital Mammography is, however, offers fantastic results, particularly for women with dense breasts. With the advent of techniques, a new and advanced version of the method has been synthesized. This is called tomosynthesis or 3D mammography. The method is found suitable for indicating the small cancers. Therefore, the need to repeat tests due to false-positives has been minimized too.

However, there are other ways for Breast cancer screening too. These involve ultrasound and magnetic resonance imaging or MRI. These tests have been found useful for women with a very high risk of breast cancer, and women having dense breast tissues. There are cases where lump of mass is found during a breast examination. For those cases, MRI is designated as the most appropriate method of screening.

Breast cancer screening tests

If you are a suspect for breast cancer, the doctor might instruct certain cancer blood tests as well as various lab tests. The various tests that are involved in such diagnosis include:

  • Complete Blood Count: This test measures the amount of blood cells of different types in a given sample of blood. Blood cancers may also be detected with this test.

Blood protein testing: This is a vital test for Breast cancer screening tests as low protein is one of the major reasons for cancerisation. The tests also helps in detecting abnormal immune system proteins.

The samples collected for the above-mentioned cancer blood tests are analysed in labs for signs of cancer. The diagnosis will help to reveal the existence of cancer cells, proteins or other substances that might cause cancer. These tests give an idea about the functioning of organs.

Cancer screening test

Screening is the method of checking for diseases before the victim gets the symptoms. The Cancer screening test involves vigorous testing to detect the possibility of breast, cervical and colorectal or colon cancer. With the upgrading of technology, experts suggest that some of the tests should be conducted within a regular interval in order to lead a safe and healthy life-style.

  • Colon Cancer: For colorectal or colon cancer, screening would help to find out any possibility of abnormal growth of precancerous polyps. These are immediately removed before these turn out into cancer.
  • Lung Cancer: The medical association of countries recommends a yearly lung cancer screening test. The test is held with low-dose tomography. These are particularly applicable for persons with history of heavy smoking or those who have left it very recently. The recommended age is between 55 and 80 years.


Frequently Asked Questions

Polyps are uncanny growths within uterus that might turn into colorectal cancer, many of these creatures have no potential to grow into cancer. It is thus hard to identify which polyps might turn into tumour. Thus the entire accumulation was earlier removed by surgery. Currently, the inclusion of colonoscopy has enabled the doctors to identify those polyps that have inherent potential to turn into tumours.

As per the latest survey, only 33% of the adults are coming to do cancer screening. The reasons for such poor response could be the following:

  • High cost and less availability of insurance coverage
  • An uncanny scare about the outcome
  • Failure of the primary doctor to suggest for the same

Recent studies about Lung Cancer has revealed that Low-dose Cancer Screening has been able to reduce the occurrence by about 20%, The patient normally get benefit with annual screening till she attains the age of 77. This also holds goods persons who have left smoking for the last 15 years.

Normally, doctor does not advise any pre-determined preparatory schedule for cancer screening. Here is no need to fast or swallow oral contrast. Normal food and drinks are required to consume. During test, he person would be asked to remove the jewelleries from the neck to upper abdomen. These can affect the image quality.

Mammography is a particular screening procedure used to identify existence of tumour cells in breast. The screening test uses low-dose X-rays for earlier detection of cancer in the chest area of a woman.
