Early Detection of Cancer:A Lifesaving Approach
Cancer, a word that often evokes fear and anxiety, remains one of the leading causes of death worldwide. However, advancements in medical science have brought about significant improvements in how we approach cancer, particularly in its early stages. Cancer prevention and early detection are among the most promising strategies for reducing cancer mortality. By identifying cancer at its earliest, most treatable stage, the chances of successful treatment and survival increase dramatically. This article delves into the various methods of early cancer detection that we implement at Elevate, namely full-body MRI scans, full-body skin check, comprehensive blood testing and mammogram screening.
Importance of early detection of cancer
Cancer begins when cells in the body start to grow uncontrollably. While our bodies constantly generate new cells, sometimes this process goes awry, leading to cancer development. Often, the earlier cancer is detected, the more likely it is that treatment will be successful. This is because cancerous cells when caught early, are usually confined to one area and have not yet spread to other parts of the body. Detecting cancer early often means that treatment can be less aggressive, reducing the likelihood of severe side effects and improving the quality of life.
The importance of early cancer detection cannot be overstated. Cancers detected at an early stage have a significantly higher survival rate compared to those found at a later stage. For instance, the five-year survival rate for localized breast cancer is 99%, compared to around 25% for breast cancer that has spread to distant parts of the body [1]. Similar trends are observed in other types of cancers.
1. Full-body MRI scan
MRI, or Magnetic Resonance Imaging, is a non-invasive imaging technology that uses magnetic fields and radio waves to create detailed images of the organs and tissues in the body. Unlike X-rays or CT scans, MRI does not use ionizing radiation, generally making it a safer option for regular screening.
What is a full-body MRI scan?
During a full-body MRI scan, you lie inside a large tube-like machine. The machine generates a strong magnetic field that aligns the protons in the body's tissues. Radiofrequency pulses are then used to disturb this alignment, and as the protons realign, they emit signals that are captured by the machine to create detailed cross-sectional images of the body.
A full-body MRI scan can detect abnormalities in nearly every part of the body, including the brain, spine, chest, abdomen, and pelvis. It is particularly useful for detecting tumours, blood vessel abnormalities, conditions like multiple sclerosis, and much more.
Advantages of a full body MRI scan
One of the primary advantages of a full-body MRI scan is its ability to detect a wide range of abnormalities in one session. It can identify potential tumours and other issues in various tissues and organs, providing a comprehensive overview of your body.
Unlike other imaging tests such as X-rays or CT scans, MRI does not use ionizing radiation. This makes it a safer option, especially for individuals who require repeated imaging or those at higher risk of radiation-related complications.
MRI provides highly detailed images, making it easier to detect even small abnormalities that might be missed with other imaging techniques. Additionally, MRIs are very well suited for examining soft tissues and organs.
Risks of a full body MRI scan scans
One of the potential downsides of a full-body MRI scan is the risk of false positives, where the scan detects an abnormality that is not cancerous. This can lead to unnecessary anxiety and additional testing, which may not be needed.MRI scans can take a significant amount of time, often up to an hour or more. Some may feel uncomfortable or claustrophobic inside the MRI machine.
2. Full-body skin check
At Elevate, our doctors perform full-body skin checks. Ensuring you have a piece of mind about any suspicious lesions.
What is a full-body skin check?
A full-body skin check is a comprehensive medical examination conducted by a healthcare professional to assess the skin for any abnormalities, including suspicious moles, lesions, or signs of skin cancer. This proactive measure is especially important for detecting conditions like melanoma, basal cell carcinoma, and squamous cell carcinoma at an early stage when treatment is most effective. The examination also helps identify other skin issues, such as chronic conditions or infections, ensuring overall skin health.
How is a full-body skin check performed?
During a full-body skin check, the doctor examines all areas of the skin, including less visible regions like the scalp, behind the ears, and between the toes. Moles, spots, or unusual skin changes are closely inspected. Photographs may be taken for monitoring. Altogether a full-body skin check can take up to 5-10 minutes, depending on your skin condition and the number of areas requiring attention. You are encouraged to point out any areas of concern during the examination to ensure a thorough review. If there are any suspicious lesions our doctors might refer you to a dermatologist for further evaluation.
Advantages of a full-body skin check
The primary advantage of a full-body skin check is the early detection of skin cancer, which significantly increases the chances of successful treatment and reduces the risk of complications. These checks also help identify precancerous changes, enabling preventive measures to be taken before they develop into serious conditions. Furthermore, a full-body skin check provides an opportunity to address other skin-related issues, such as infections, rashes, or the effects of aging and sun damage. Regular screenings promote better skin health and peace of mind, empowering individuals to take proactive steps in managing their overall well-being.
3. Mammogram screening
Mammograms have long been a cornerstone of breast cancer screening in women and remain one of the most effective tools for the early detection of this common cancer. Generally, mammograms are used as part of routine national screening for women, particularly those over the age of 50 or with a higher risk of breast cancer. Here at Elevate, we could offer the option of mammogram screening beyond the national screening program after investigating your risk.
What is a mammogram?
A mammogram is an X-ray of the breast used to detect abnormalities, such as lumps or calcifications, that may indicate the presence of breast cancer.
How does a mammogram work?
During a mammogram, the patient's breast is placed on a flat surface and compressed with a paddle. This compression spreads out the breast tissue, allowing for a clearer X-ray image. The procedure typically takes about 20 minutes, and the resulting images are examined by a radiologist for signs of cancer.
Advantages of mammogram screening
Mammograms have been extensively studied and are proven to reduce breast cancer mortality by detecting cancer early when it is most treatable.
Mammograms are a quick procedure and are widely available at hospitals, clinics, and specialized imaging centers.
Mammograms can detect cancers that are too small to be felt during a physical exam, allowing for early intervention.
Risks of mammogram screening
While the radiation dose from a mammogram is low, there is still a small risk associated with repeated exposure over time. However, the benefits of early detection generally outweigh this risk.
As with other screening tests, mammograms can produce false positives or false negatives, leading to unnecessary biopsies or missed diagnoses.
The compression of the breast during a mammogram can be uncomfortable or even painful for some women, although the discomfort is usually brief.
4. Comprehensive blood testing
Comprehensive blood testing is a detailed evaluation of various blood components, including red and white blood cells, platelets, electrolytes, enzymes, hormones, and other biomarkers. These tests provide crucial insights into a person’s overall health, identifying abnormalities that may indicate underlying medical conditions. By analyzing these results, healthcare providers can monitor organ function, detect nutritional deficiencies, and identify potential signs of diseases such as infections, autoimmune disorders, or cancer.
How comprehensive blood testing can provide clues for diagnosing cancer?
Comprehensive blood testing can reveal subtle biochemical and cellular changes that may signal the presence of cancer. For example, abnormal levels of tumor markers—substances produced by cancerous cells or the body in response to cancer—can suggest specific types of malignancies. A complete blood count (CBC) might show irregularities such as anemia, high white blood cell counts, or unusual platelet levels, which could hint at the presence of solid or blood cancers. Additionally, metabolic markers can highlight disruptions caused by tumors in organs such as the liver or kidneys. While blood tests alone are rarely definitive, they are an invaluable part of a broader diagnostic process.
Advantages of combining comprehensive blood testing with imaging
Combining comprehensive blood testing with imaging enhances diagnostic accuracy and allows for a more thorough evaluation of potential health concerns, including cancer. Blood tests provide molecular and biochemical data, while imaging techniques such as the full-body MRI scan offer visual evidence of abnormalities in tissues and organs. Furthermore, the combination facilitates earlier detection, improving the chances of successful treatment and enabling personalized care plans.
Conclusion
Early detection of cancer is a critical factor in improving survival rates and reducing the burden of this disease. Advances in medical technology have provided us with powerful tools to detect cancer at its earliest stages when treatment is most likely to be successful. Full--body MRI scans, full-body skin checks, comprehensive blood testing, and mammogram screening each offer unique advantages and carry certain risks.
