World Lung Cancer Day: What is liquid biopsy, how to treat cancer easier

Lung cancer is one of the most fatal diseases in India, but now patients are expected to get relief from painful surgery and complex processes. The reason for this is a new liquid bio -biopsy technology. This is a non -invasive examination method in which cancer is identified by taking only blood samples. In such a situation, on the occasion of World Lung Cancer Day, today we will tell you how this technology is bringing revolution in the treatment of cancer.

Lung cancer is the biggest challenge to detect late

According to the 2025 report by the National Institute of Health, 5.9 percent of the total cancer cases in India are lung cancer. Whereas the number of deaths due to this is 8.1 percent. According to doctors, early symptoms such as persistent cough, fatigue or chest pressure are usually ignored. At the same time, by the time you reach the hospital, the cancer has spread in the body, which makes the treatment difficult.

Traditional biopsy is not possible every time
Tissue biopsy has been used till now in the identity of clothing cancer. Which is examined by removing tissue from the tumor. But sometimes the tumor occurs in parts of the lungs where it is difficult to reach as well as this process can be risky for elderly, heart or diabetes patients. Apart from this, the biopsy taken once does not give information about the entire tumor every time.

Liquid biopsy option without surgery check
Liquid biopsy is a modern and less complex technique. In which the patient’s blood is examined and found out whether it has genetic disturbances or tumor DNAs related to cancer. This not only provides relief to the patients but also helps the doctor to understand the genetic profile of cancer. The special thing is that this technology can identify gene mutations which are common in Indian patients. With this, doctors can start targeted therapy which can prove to be more effective than traditional chemotherapy.

Monitoring can also be kept during treatment
Another specialty of liquid biopsy is that it can be repeated several times during treatment. With this, the doctor can know how the patient’s disease is reacting and there is no resistance to tumor medicines. If this happens, doctors can immediately change the direction of treatment.

Improvement in technology and expansion in India rapidly
Liquid biopsy is now being used regularly in many cancer institutions in India. Scientists are working on increasing its sensitivity, reducing costs and improving accuracy in different cancer. As the practice of personalized medicine increases, this technique will join the mainstream of treatment.
