The diagnosis is one of the most important factors which influence the outcome of diseases but still it is ignored on a large scale by people. In cases of chronic diseases such as cancer, HIV-AIDS, and tuberculosis, the problem of late diagnosis is severe which causes high number of casualties. The physical symptoms may take time to appear in some cases of cancer. When a person starts to notice the symptoms, the disease is already in a late stage. In India, 70 percent of cancer patients consult the doctor at the terminal stage, according to doctors. Thus, late diagnosis of diseases is a serious concern globally and rigorous research is being done to invent innovative techniques to tackle this problem. In this study, the cases of breast …show more content…
A cancer tumor often produces a specific protein in the blood that serves as a marker for the cancer. Circulating tumor cells are cells that break off from the cancer and move into the blood stream. Protein markers and circulating tumor cells can be measured with simple blood tests. This method is not specific in nature as one marker may be common for multiple types of cancer. Hence, other tests are performed to confirm the diagnosis of breast cancer.
For example, presence of CEA (carcinoembryonic antigen) marker is associated with colon, lung, and liver cancer. It also suggests that breast cancer has travelled to other parts of body. iii) Breast MRI: MRI, or magnetic resonance imaging, is a technology that uses magnets and radio waves to produce detailed cross-sectional images of the inside of the body. Breast MRI has a number of different uses for breast cancer, including: screening high-risk women (women known to be at higher than average risk for breast cancer, either because of a strong family history or a gene abnormality), and gathering more information about an area of suspicion found on a mammogram or ultrasound, monitoring for recurrence after treatment. iv) FISH Test: Fluorescence In Situ Hybridization (FISH) is a test that maps the genetic material in a person’s cells. This test can be used to visualize specific genes or portions of genes. FISH testing is done on breast cancer tissue removed during biopsy to
A test of a sample of tissue taken from the lining of the uterus (endometrial tissue biopsy).
Mammograms are breast cancer screenings and are of great importance since they detect if indeed a malignant tumor is present and if so what stage it is in (Stephan, 2010). Cancers can be detected at stages I, II, or IIA (Haas et al., 2008).
The M category tells whether there are distant metastases (spread of cancer to other parts of body).
Magnetic Resonance Imaging, or commonly known as MRI, is a technique used in medicine for producing images of tissues inside the body. It is an important diagnostic tool because it enables physicians to identify abnormal tissue without opening the body through surgery. MRI lets physicians see through bones and organs. MRI does not expose the patient to radiation, unlike tests that use X-rays. MRI provides an unparallel view inside the human body. It is the method of choice for the
4+1 Analysis: The Fall of the House of Usher The tone of the beginning of the story was foreboding and gloomy. When the narrator arrives at the House of Usher, he uses the word “melancholy” to describe the feeling of the house and says it has “a sense of insufferable gloom” (pg. 69). The house was falling apart, and it appeared as if Roderick Usher was too. He wrote to the narrator, explaining that his sister will die soon. This foreshadowing adds to the apprehensive tone.
Another biomarker that can be observed in response to cancer is ct-DNA. Ct-DNA refers to fragments of DNA from tumors found circulating in the blood stream. A recent study indicated that observing ct-DNA could have multiple useful applications for oncologists. Ct-DNA analysis during treatment could serve as an indication of how tumors react to treatment methods and whether recurrence is likely. Detecting ct-DNA in the bloodstream could even serve as an early sign of cancer, observable before imaging tests even show tumors. However, ct-DNA analysis has not yet proved to be a replacement for LDCT
If your doctor thinks your cancer may have spread to other parts of your body, you may need more tests, such as chest x-rays, CT scans, bone scans, or MRI scans. CT, PET, Bone Scan, and an MRI these are test to know if the breast cancer has spread.
Fluorescence in situ hybridization (FISH) is a technique used to locate the position of specific DNA or RNA sequences in the cell. In situ hybridization is a process that relies on the ability of double stranded DNA or RNA to re-anneal after it has been denatured. A labeled probe is used to bind to the single strand of genetic material. The labeling allows for visualization of this region of the DNA or RNA template. FISH used fluorescently labeled nucleotides in the probe. The probe must be complementary to the DNA or RNA template strand for efficient binding. The fluorescent copy (the probe) will bind to the template strand, hybridizing them
Detection of breast cancer can be made at an early stage through screening. Screening refers to the various tests and examinations that are carried out on the breasts of a person to detect the disease at the earliest, even before the actual symptoms of the disease starts to show. Usually breast cancers that can be felt and detected are cancers that have grown larger in size and that which in usual cases has spread to regions outside the breast. The treatment in such cases is very complex. Breast cancers can be treated successfully if it is detected very early, and before the actual cancer symptoms starts to show.
There is a breast cancer test. A breast cancer MRI can help you detect early breast cancer. The test usually detects the
The test uses gene sequencing technology to spot traces of DNA related to different cancers in screen blood samples. To be precise, it looks at 96 genetic markers associated with breast, ovarian, lung, colon and melanoma cancers - ones that have specific treatment regimens and are well known. Many cancer
Bone scans and x-rays -- these tests look for spread of cancer to the bones.
Carcinoembryonic antigen (CEA) is a tumor marker that can be detected in the blood of clients with colorectal cancer. CEA level is used to estimate prognosis, monitor treatment, and detect cancer recurrence.
In today’s growing, technological world, people rely on the media more than ever to get information about everyday occurrences and big news, but could this very system be painting a particular group in a bad lighting and giving them unfair judgement? Most, if not everyone, have seen one or two movies or television shows where teenagers are portrayed as arrogant, conceited, impulsive nuisances that are only good for causing problems, but this is not true. Media paints us in a bad light, making it seem as if all teenagers are out of control and chaotic, but in all actuality, teenagers can prove to be very responsible, considerate, and can even think things through, contrary to popular belief. While I can see why many people consider teenagers to be careless, it is unfair to assume that all teens are just because of the few
Personal health record (PHR) is an emerging model of patient-centric health information exchange system, which has been often outsourced to be stored at any third party locations, such as cloud service providers. However, there have been wide privacy concerns as the personal health information could be exposed to unauthorized parties and to those third party servers. To assure the patients control over accessing their own Personal Health Records, it is required to encrypt the PHRs before outsourcing. Yet, there are issues such as risks of scalability in key management, privacy exposure, flexible access, and efficient user revocation, has been remained the most important challenges toward achieving fine-grained, cryptographically enforced data access control. For, designing the above system different methods of encryption techniques have to be studied and see what are the main advantages and disadvantages of the system as few of disadvantage in one system can be used advantage of another system. We have to study how data is stored in cloud system and how users can access them. To design a system such that it has different level of accessing flexibility such that the owner can choose which accessing is required for different user such that data tamper and data corruption can be eliminated. To design a system which has time limited access and data
