  • Essay / Review of Issues in Cancer Detection

    The world faces many challenges in cancer detection today, including the ability to diagnose cancers earlier, finding less invasive diagnostic techniques , less expensive detection tools, and more precise ways to detect and remove cancerous tissue (1-4). Cancers are much easier to treat and have much higher survival rates when detected early (1). Biopsies for cancer detection are invasive and sometimes painful for the patient. The use of alternative methods such as biomarkers would therefore make their experience more bearable (1-3). Determining where healthy tissue stops and cancerous tissue begins is another challenge, so fluorescence imaging to see the contrast between good and bad is useful for surgeons to detect what needs to be removed (4). These are just a few topics that highlight the difficulty of detecting cancer. Say no to plagiarism.

Electrochemical detection of biomarkers is gaining popularity due to its low cost and simplicity of detection, but a better production method is needed. HER-2 detection methods often require invasive biopsies in order to detect tumor tissue. HER-2 can also be found in the serum of hospitalized patients, but more sensitive measuring tools are needed to detect the still low concentrations so they can be detected quickly. Current methods of producing electrodes require the creation of a template, which is time-consuming and expensive. Production also involves expensive facilities, many of which generate hazardous waste. Disposable sensors, produced quickly and easily, hold promise for point-of-care detection. Inkjet printing is able to overcome existing obstacles by efficiently producing designs from digital files at low cost and producing small amounts of material waste. Detection of bladder cancer by biomarkers in urine Bladder cancer is the most common cancer of the urinary tract. Biomarkers in urine are necessary for non-invasive diagnosis, as well as for earlier diagnosis, because typical symptoms may not appear until later stages of cancer (3). Today, bladder cancer is usually diagnosed through a process called cystoscopy. This procedure involves the insertion of a hollow tube and aliens into the urethra and into the bladder. Unfortunately, this operation must be performed by a urologist, is often painful for patients and takes time. Biomarkers from biological fluids would provide a more comfortable and less invasive alternative, and urine has proven to be a good source for this type of detection. Urine could be a good source of specific bladder cancer biomarkers due to its proximity to the target organ. Biomarkers can contribute to earlier detection of cancer, helping to reduce mortality rates and the number of invasive procedures needed. Fluorescence-enhanced imaging of pancreatic cancer Pancreatic ductal adenocarcinoma, or pancreatic cancer, is a very fatal disease and the only cure at present is surgical resection (4). Detect with.
