Indian women consider to be their duty to take responsibility of the first husband, children and the rest of the family. In the affair of all these, she forgets to take care of her own. They only ignore small problems, which they have to bear the loss with great trouble. Actually, due to this lifestyle, women are not very serious about their health. Such a trend is seen not only in aging, but also in young women and women. This is the reason that dangerous diseases like cervical cancer gradually make them their victims. Let us know what is the right age for screening cervical cancer in women? Which test is the best for this and how much does it cost?

AIIMS Delhi doctor said this
Let us know that a workshop was held in AIIMS Delhi recently on the issue of cancer. In this, Dr. Abhishek Shankar, Assistant Professor of AIIMS Radiation Oncology Department, said that if you are 30 years or more, then there is no need to do repeated screening of cervical cancer. Now such an option has been received in the form of HPV DNA test, which gives information about the upcoming risk of cancer in five years. He said that HPV DNA test not only identifies the initial stage of cancer, but it also catches the infection of the virus.

How is this test?
According to Dr. Shankar, HPV (Human Papillomavirus) DNA test gives accurate results up to 95 % and it is more effective than the Pap Smear Test. In this test, samples are taken from women’s cervix i.e. cervix. Within a few minutes, doctors know whether DNA of HPV virus is present in the woman’s body. He told that this test can be done in AIIMS. The special thing is that women can also give samples for this test.

What is the condition of cervical cancer in India?

According to Dr. Suman Bhaskar, head of AIIMS Radiation Oncology Department, cervical cancer cases are increasing rapidly in India. Every year more than 75 thousand women die due to cervical cancer. At the same time, 70 to 80 percent of cases come up when the disease has reached its last stage. If the disease is detected in the beginning, then treatment is quite easy. This disease can be avoided only by surgery or radiation.

How is the DNA test, what will help the badly burnt dead bodies in Ahmedabad plane crash?

The plane crash on June 12 in Ahmedabad, Gujarat has shook the entire country. Air India flight from Ahmedabad to London crashed a few minutes after the AI-171 takeoff, in which 241 passengers died. Former Gujarat Chief Minister Vijay Rupani also died in this terrible accident. The bodies of the victims of the accident have been burnt so badly that it is impossible to identify them through traditional methods. In such a situation, the method of DNA test is left for identification. Do you know how DNA test is done? Which part of the badly burnt bodies in Ahmedabad plane crash will help in this work? At the same time, how many distant relatives are taken help in this investigation? & Nbsp;

what is DNA test?

DNA ie deoxybonucleic acid test is a scientific technique, which checks the genetic structure of a person and identifies it. The DNA of every person in the world is different and it is found in the nucleus of cells. This technique is especially effective when it is extremely difficult to identify bodies. The bodies have been severely burnt in the Ahmedabad plane crash, due to which DNA test is the main source of identity. & Nbsp;

How DNA Test is done? & Nbsp;

DNA testing is a difficult, but systematic process. & nbsp; It is examined under several stages. & nbsp;

sample collection:

How samples are taken from bodies? samples of bones like femur, humus or rib are taken to extract DNA from badly burnt bodies. Apart from this, teeth or remaining tissue are also very effective. Actually, bones and teeth are more important, because on high temperature also DNA is preserved in them. & Nbsp;
samples from relatives: After this, blood, saliva, or cheek cells (bookkel swabs) are taken from family members. These samples are used for matching the DNA of the deceased. & Nbsp;

cleaning and preparation of samples

It is very difficult to remove DNA from burnt bodies in the accident, because high temperatures and chemicals can destroy DNA. In such a situation, the sample is first cleaned, so that outdoor pollutants like debris or microorganisms can be removed. For this, the sample is washed with tap water and 100% ethanol. Steril instruments are used to grind bones and teeth in powder. & Nbsp;

How is DNA extracted from bones?

Organic extraction process is used to remove DNA. Under this, DNA is separated by putting samples in chemical solution. In the Ahmedabad accident, the bodies have been affected by 1.25 lakh liters of fuel fire. In such a situation, the quality of DNA can be affected. However, new technology manages to extract DNA from burnt remains.

How much DNA is necessary for investigation? & nbsp;

The amount and quality of the extracted DNA is examined through real-time PCR (polymerase chain reaction). In such a situation, it is first ensured whether DNA is enough for examination or not.

How DNA Profiling is?

Short tendom repeats (STRs) are examined in DNA profiles. These are parts of DNA, which are different in every person. After this DNA profile is prepared. About 1000 DNA tests are being done in the Ahmedabad accident, including matching the samples of the dead and their families.

How far relatives go to samples?

The DNA profile of the deceased is mixed with family samples. For this, matching with the DNA of parents or children is considered more accurate, because there is more genetic equality between them. If investigation is being done under an accident like Ahmedabad plane crash, then this process of DNA test may take several days.
