High Prevalence of Cancer and Significant Development in Biopsy to Boost Demand for Cancer Diagnostics

Cancer diagnostics is the use of one or more approaches to diagnose cancer, which include, physical exam, blood test, computerized tomography (CT) scan, bone scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, ultrasound, x-ray, and biopsy among others. Early detection of cancer helps you be prepared for treatment if you are diagnosed with cancer. Unfortunately, some people are not diagnosed until they reach the advanced stages of the disease. Cancer usually develops slowly over time and by the time it shows symptoms, it has spread to other parts of your body.

High prevalence of cancer is expected to boost demand for cancer diagnosis. For instance, according to the American Cancer Society, in 2019, there will be an estimated 1,762,450 new cancer cases diagnosed and 606,880 cancer deaths in the U.S. X-rays are designed to aid doctors in detecting cancerous cells and tissues. During a normal mammogram, a small lump is made on the tissue with the aid of an x-ray rod. Follow-up scans will help doctors learn whether the lump itself has cancerous cells. If so, doctors may perform a biopsy to find out if the cancer has spread. Some types of cancer cannot be detected through an x-ray; for this reason, a CAT scan or magnetic resonance imaging may be used to follow up on the disease.

PET scans and magnetic resonance imaging (MRI) are two more diagnostic radiology techniques commonly used by doctors. PET scans use gamma rays, while MRI uses sound waves. In a typical MRI, a thin metal probe is placed inside the body's tissue. Doctors use the images to determine whether abnormal growths or other abnormalities are present.

A physical examination by a trained medical practitioner is essential prior to the next step, a biopsy. During a biopsy, doctors remove a small piece of tissue sample from the growth and examine it under a microscope in order to find out if it contains cancerous cells. Depending on the type of cancer and the location of the growth, doctors make a decision as to which pathologists to consult. If there is no visible tumor or growth, the patient is usually sent home to recover at home. If there is, additional treatment may be required in order to kill the cancerous cells.

If the biopsies show that the cancers have spread, the doctor will perform a surgery known as a needle biopsy. During this procedure, a small amount of tissue sample from the area will be removed using a small needle. The doctor will then insert the sample into a special device that will allow them to identify any cancerous cells present in the tissue sample. If necessary additional biopsies will be performed in order to identify the extent of the disease and to rule out more serious cancers. There are several advantages of biopsy. Biopsy is less invasive and in liquid biopsy the test results are typically available much earlier than a standard tissue biopsy. This has led to significant development in biopsies. For instance, in December 2019, Medtronic plc received the U.S. Food and Drug Administration clearance for its Stealth Autoguide system, for biopsy procedures, stereoelectroencephalography (sEEG) depth electrode placement, and for the positioning of the Visualase bone anchor, which is used for catheter placement.

Increasing Initiatives to Digitalize the Healthcare Sector Is Expected To Boost Demand for Electronic Medical Records

Image
  An electronic medical record (EMR) is essentially a systematized collation of individual patient and family health information in an electronic format. This information is then shared across several health care locations. This will save time, money and provide patients with more comprehensive care. Increasing initiatives to digitalize the healthcare sector is expected to boost demand for EMR. For instance, in November 2019, Germany introduced Digital Supply Act to digitalize healthcare. Under the new legislation, doctors will be able to prescribe digital health apps to patients, which can be reimbursed by the country’s statutory health insurance. There are several advantages to using EMR. The main advantage is that you do not need to wait for the paper records to go through the paper processing before you can use them. Another advantage to electronic medical records is that they allow for greater privacy. Electronic health records allow only the doctor to see these rec
