A woman’s body is likely to change with age, time and environmental factors. Sometimes, the changes that seem normal can be signs of cancer, though.
Some of the cancers that most often affect women are breast, endometrial, ovarian and cervical cancers. Knowing about these cancers and what you can do to help prevent them or find them early may help save one’s life.
The symptoms may be easy to overlook and are usually diagnosed at a late stage when they are generally more difficult to treat. Efforts should be made to detect cancer at a very early stage by educating population about the risk factors.
There are several methods of diagnosing cancer. With advances in technologies that understand cancers better, there is a rise of number of diagnostic tools that can help detect cancers. Once suspected, diagnosis is usually made by pathologists, onco-pathologists and imaging radiologists.
There are a few limitations of attempting to diagnose cancers with conventional biopsy techniques guided by ultrasound or CT, like rupture of the cystic mass when a biopsy needle is inserted with possible spread of the tumor to other sites, or missing cancerous cells since some parts of the cyst may not contain cancer.
At Datar Genetics Scientists have studied innovative methods to detect cancer by identifying markers specific to the disease present in the blood. This method is called ‘Liquid biopsy’, which is simple, safe, sure and works on a highly sensitive platform.
In liquid biopsy, fluid or blood drawn from the individual is examined to find cancer cells and other biomarkers within the blood. The test utilizes gene sequencing to compare genetic markers within the person’s blood sample. Those markers are then contrasted with genetic markers found in common cancers such as ovarian, breast, lung, endometrial and colon cancers. If there are genetic markers that match, then the test has found evidence that the patient is at risk of contracting said cancer in the future. It is particularly helpful when a tissue biopsy can’t be done easily or if tissue is unavailable for any reason or if the original starting point (primary) of cancer is not known.
Liquid Biopsy can be used at various stages – for Cancer diagnosis, for early detection, for guidance on therapy management and for recurrence monitoring. It can also provide therapy guidance and helps monitor therapy success. It also helps to predict the response of patient to a drug and also if tumor has developed resistance to the treatment.
In the field of oncology, where innovations come and go without lasting impact, this novel non-invasive liquid biopsy is a life saver.
