The Evolution of Cancer Treatment
Cancer generally returns after it has been surgically excised, as ancient doctors and surgeons were aware of. Although some ancient civilizations made great strides in medicine, there was minimal advancement in the treatment of cancer. The notion that cancer cannot be treated in some cases has lingered into the twenty-first century. This has only helped to increase people's fear of the illness. Even today, some people believe that all cancer is incurable and delay seeking medical attention until it is too late for the best course of action. The evolution of cancer therapies has been gradual. The ancients understood that once a cancer had spread, there was no curative cure and that involvement might even be dangerous. Galen discussed surgical treatments for breast cancer in his writings, provided the tumor could be entirely removed at a young age. Surgery back then was quite basic and had numerous drawbacks, including blood loss. Major developments in general surgery and cancer surgery weren't made until the 19th and early 20th centuries.

Before the development of anesthetic, there were outstanding surgeons. For their quick and accurate surgery, John Hunter, Astley Cooper, and John Warren received praise that endured. However, the field of medicine grew so quickly with the invention of anesthesia in 1846 that the following century came to be known as "the century of the surgeon." Today, fiber optic equipment and tiny video cameras are used by doctors to view the inside of the body. Through tiny tubes inserted into tiny skin incisions, surgeons can perform operations while utilizing specialized surgical instruments. These tools can be used to examine and operate inside the chest or abdomen (laparoscopic surgery) (thorascopic surgery).
A similar tool called an endoscope can be inserted through natural body openings like the mouth or anus to remove certain cancers from the colon, esophagus, or bladder. Less invasive approaches to tumor removal without removal are being researched and/or used. Using liquid nitrogen spray or an extremely cold probe, cryosurgery—also known as cryotherapy or cryoablation—freezes and destroys aberrant cells. Instead of using a scalpel, lasers can be used to cut through tissue or to vaporize (burn and eliminate) malignancies of the skin, liver, rectum, cervix, and other organs. In order to kill cancer cells by heating them, radiofrequency ablation sends radio waves to a small antenna positioned inside the tumor. This has led to the introduction of precision surgery.
Precision Surgery
The enormous technological improvements we have seen in the previous 25 years have been largely ignored by the healthcare industry. In fact, a large portion of our present surgical practice hasn't changed in decades. While we have made efforts to lessen the traumatic nature of surgical procedures by utilizing keyhole instruments when appropriate, the technology that underlies these minimally invasive techniques is still quite primitive. And it's only recently that we've started using so-called surgical "robots," which provide surgeons the ability to carry out trickier operations using flexible, articulating equipment. We are starting to get a glimpse of an exciting future, the coming surgical revolution, thanks to increased cooperation between engineering, computer science, and surgeons.
Precision surgery is much more than just being an expert at technical maneuvers. A more complex definition of such precision entails a deeper comprehension of the biochemical underpinnings of disease, which is then contested with targeted, strategic therapies. Precision surgery strives to apply surgical therapy to those most likely to benefit rather than treating many to the advantage of a select few, and to prevent surgery in those condemned to failure. The idea of precision may be outdated in the field of surgical oncology. The best way to put this idea into perspective is to remember what Dr. Blake Cady said in his 1996 Presidential Address to the New England Surgical Society: "The art of surgical oncology is to apply basic concepts flexibly to the particular patient."
Precision surgery has advanced significantly in surgical oncology during the past century, with the steady adoption of minimally invasive treatments thanks to the combined efforts of surgeons, researchers, and business. Image-guided surgery, or the employment of chemical agents and detection methods to offer guidance during surgery, is one of the ideas that is being researched more and more. The main goal in this case is to completely remove the cancer while maximizing functional results after the intervention. The exact placement of the anatomical target, safety margins, and full excision, while sparing as much healthy tissue as feasible, are the main concerns in this method.
Using surgical robots like the DaVinci, surgeons may conduct procedures with a level of accuracy never before possible. The possibility of operating on early-stage tumors or tumors adjacent to delicate organs may increase more than ever if the robot is made to function as an extension of the surgeon's intellect and abilities. Modern surgical robots contain 3D cameras that can simultaneously stream and record operations. The extra benefit of the robot is that it helps the surgeon do suturing, tissue dissection, and tissue retractions with more accuracy.

The Goal of Precision Oncology
Precision oncology is the molecular profiling of cancers to find changes that can be targeted. In layman's words, it's the science of tailoring a patient's treatment to the molecular characteristics of their cancer by using genetic information from the patient. An exciting period in the fight against cancer is being ushered in by the rise of precision oncology and the development of more individualized and targeted treatment approaches. Precision oncology is a dynamic, intriguing field of study that is increasingly finding its way into conventional cancer practice. There is no established name for this branch of medicine because it is new. In addition, precision oncology is known as:
- Personalized cancer treatment
- Individualized cancer treatment
- Personalized medicine
- Molecular medicine
- Precision medicine
Improving patient outcomes is precision oncology's ultimate goal. "Traditional" cancer treatments like chemotherapy are cytotoxic to the majority of cells, which means that in addition to destroying cancer cells, they can also harm healthy cells. Chemotherapy has the potential for severe negative effects, even though it is a mainstay of cancer treatment for many people and can be quite effective. Through multiplex molecular testing, including NGS, the objective of precision oncology has started to be achieved. Oncologists should be knowledgeable about the technical elements of NGS to make it easier to choose the most suitable and affordable testing platform. The type of tissue to use, the time of the illness course profiling, the size of the panel to order, and the level of clinical annotation reported are all factors to be taken into account while performing molecular testing. Non-small cell lung cancer serves as a model for precision oncology at the time of diagnosis of advanced disease, during treatment, and at the time of progression due to its actionable biomarkers. Participation in clinical trials and the sharing of linked molecular/clinical data sets are strongly encouraged. Interpretation of molecular data to support best practice remains a difficulty.
Delivering the appropriate cancer treatment to the appropriate patient at the appropriate dose and time is the sole objective of precision medicine. The advent of precision oncology was made possible by several lines of research coming together almost simultaneously. The idea that somatic mutations serve as the starting point for the genesis of cancer underpins precision oncology. Oncogene mutations that make them constitutively active are referred to as driver mutations and serve as the primary regulators of the development of malignancies. In contrast, tumor suppressor genes, which are naturally involved in regulating tumor etiology, might advance cancer when they become inactive due to mutation or allele loss.
Precision Oncology Driving the Future of Healthcare
Precision oncology refers to a broad range of cancer treatment methods that are specifically adapted to the individual biology of each patient's condition. To choose treatments without regard to the type of cancer, strategies range from the use of targeted therapies to the use of data from next-generation sequencing. Precision oncology promises the promise of greater effectiveness, better therapy, and a decrease in costly and ineffective therapies. The oncological ecosystem still needs to be prepared in order to fully utilize the benefits of customized treatment in cancer, though. Precision oncology's significance will undoubtedly increase over the next years, but in order to reach the required objectives, a clear road must be charted.
The development of precision medicine in the field of oncology is facilitated by the growing accessibility of tumor genetic testing and targeted cancer medicines. In order to make it easier for oncologists and patients to make clinical decisions based on genetic information, precision oncology knowledgebase offer a method of organizing clinically pertinent genetic data. Precision oncology knowledgebase have been developed by numerous organizations and businesses with different users in mind. These knowledgebase include data on cancer-related genetic variations and the diagnostic, prognostic, and therapeutic implications that go along with them, but they frequently have different content curation strategies, user interface designs, and user experiences.
Oncologists should use several knowledgebase in their practice so that they can complement one another. In order to ensure that the comprehensive knowledge from all sources can be consolidated, convergence toward common standards and formats will be necessary in the future. This will help the oncology community go closer to realizing the vision of precision oncology. Using tumor molecular profiles to determine the diagnostic, prognostic, and therapeutic implications relating to the particular cancer being studied is known as precision oncology. Fundamentally, tumor biomarkers are thought to be indicators of disease phenotype, clinical outcomes, and therapeutic responsiveness in precision oncology.
High end diagnostics for cancer care are delivered in large part by the fields of radiology and image sciences. Our ongoing research and development in these crucial areas has had a hugely beneficial impact on the fight against cancer. Interventional technologies have replaced merely diagnostic ones in radiology. The use of new contrast agents in MRI, X-ray, and ultrasound allows doctors to plan treatments and make diagnoses with better accuracy than ever before. We make sure to have the most up-to-date technology, whether it be the Philips Gemini Time-Of-Flight, the 64-Slice PET-CT scan system, the 64-Slice Multi Detector Computerized Axial Tomography scan, or the 3D Mammography, to ensure better and earlier cancer diagnosis.
