Introduction
Every treatment intervention necessitates certain precautionary initiatives, and so do the cancer treatments. Adhering to specific preventative proposals palliates the gravity of adverse reactions that would otherwise accompany and trouble the patients. Precautionary initiatives not only upscale the safety profile but also render comfort and ease for the patients throughout the therapy. Not all precautionary steps are to be instituted by the patients; some ought to be practiced and taken care of by the medical professionals involved in the treatment planning and execution process.
What Is Radiation Therapy?
Radiation therapy is a therapeutic intervention that is being instituted for various cancers. Cancer, an alarming and grave health concern, emerges as the cells breed haphazardly and irresistibly, bringing forth cellular mass with no specific functions or actions. Radiation therapy employs radiations of remarkably higher intensity. These radiations aim to target the cancer cell’s genetic material (DNA- deoxyribonucleic acid). The stronger intensity expedites and gravitates the defacing and ruination of the DNA, which in turn murders and finishes off the cancer cell.
Gamma rays, high energy electrons, and X-rays are the ionizing radiations employed in radiation therapy. These radiations bring forth genetic transfiguration through derangement in the DNA structuring. It is the genetic makeup that governs each cell’s assignments and functions. Genetically deranged cancer cells endure cellular destruction and eventually die out. Radiation therapy is designated as an age-old cancer therapy, and it has been implemented and practiced ever since the 1980s.
External and internal radiation therapy are the two discrete subsets of radiation therapy. External radiation therapy is the routinely advocated one where radiation beams are directed and addressed from an external machine to the cancerous part. The machine gyrates around the patient (in the repose state), which ascertains that the radiation strikes the cancer cells from different angles. The dimensions of the radiation beam are critical in external radiation and are instituted such that the scope for radiation proneness for the healthy cells could be kept at least possible.
In internal radiation therapy (brachytherapy), the radiation source that could yield and deliver radiation is stationed and embedded into the cancerous part or proximate to it. Internal radiation therapy, when intended for a long-term course, is achieved by embedding the radioactive (capable of yielding radiation) implant.
What Are the Precautions to Be Taken Before Radiation Therapy?
In radiation therapy, radiation is employed to target and turn down cancer cells. However, these radiations could also harm and mutilate the healthy cells in the body. Likewise, radiation therapy also poses the threat of unwanted radiation exposure to caretakers and others with whom the patient interacts closely and frequently. Therefore, it is imperative to ensure and warrant radiation therapy safety. There are certain precautionary initiatives and strategies that one ought to implement all through radiation therapy. This downgrades the risk and hazard prospects concerning radiation therapy.
1. Radiation Dose: Though radiation therapy is targeted at cancer cell destruction, the dose of the exposure ought to be worked out, underscoring minimal harm to the healthy cells. The medical team, through meticulous review and analysis, devises the radiation dose, giving equal weightage to the safety and efficacy attributes.
2. Protective Gears: Specialized protective amenities are instituted to shield other highly receptive structures from radiation. Thyroid shields (worn over the neck to mask the radiation to the thyroid gland) and lead aprons are the personal protective gears that are instituted to shield off radiation from gaining access to other critical areas where it is not intended. These protective gears are advocated primarily with external radiation therapy.
3. Measures to Screen Radiation Leak: Internal radiation therapy necessitates more precautionary measures and initiatives as the radiation source is within the patient’s body. In such cases, the patient itself acts as a mobile radiation source, giving off radiation, though of minimal dose. Owing to the threat of radiation exposure, such patients ought to keep a specific gap or distance from others. Minimizing visitors and obviating close contact with patients are other strategies to downturn the propensity for radiation exposure for others. Expectant women and infants better not be in such patients' proximity.
Radiation therapy could also be employed through pill formulations, where the radioactive entity is being formulated into a pill form. Those pills ought to be housed in protective receptacles that could retain and contain the radiation within them, thus mitigating the propensity for radiation leak into the drug proximity.
4. Quality Control Checks for the Radiation Equipment: Before initiating radiation therapy, the medical team has to ascertain the radiation equipment’s working efficiency and accuracy in delivering the radiation in the specified dose. Quality control checks are to be instituted periodically to weigh up the accuracy attributes.
5. Rule out Pregnancy: Prior to radiation therapy, the female patient who has been advocated for radiation therapy must disclose pregnancy or suspected pregnancy. Radiation therapy, when instituted on an expectant woman, could bring forth grave repercussions for the fetus (baby inside the womb). For patients under childbearing age, the pregnancy status ought to be made conclusive by definitive pregnancy tests.
6. Medical Background: Ensure that the medical team is updated with all the health information on the patient who is being chosen for the therapy. The medical team ought to be conscious of the implanted organ-supporting units in the body, if any, owing to gravity for the deleterious outcomes that the radiation could bring out on these devices. Cochlear implants (for aiding hearing) and pacemakers (modulate and tune the heart beating) are two organ-supporting devices that one should never miss to bring to the doctor’s attention prior to radiation therapy.
7. Skin Protection: Radiation therapy, in most instances, could invoke skin issues. Skin peeling (flaking), itchiness (pruritus), dryness, and soreness are inflicted by radiation. By incorporating certain precautionary initiatives, one could mitigate the gravity of skin issues. Keeping skin clean is highly appreciated. In addition, ensure that the skin is well-hydrated and moisturized as it buttresses the integrity of the skin layer. Soaps or other lotions that draw out excess skin’s moisture content are not advocated during radiation therapy. However, just before radiation exposure, keep the skin bare with no lotions or chemicals.
Conclusion
Radiation therapy could bring forth various adversities in the patient’s life. Precautionary strategies came into the picture as an initiative to downgrade the adversities concerning radiation therapy while retaining the effectiveness and treatment outcome unimpaired. Precautionary initiatives from the patient and medical team together downturn the prospects for radiation-triggered adversities. Devising and complying with the exposure dose at the minimum possible to achieve the intended outcome and taking initiatives to safeguard receptive bodily structures from becoming susceptible to radiation are the basic precautionary approaches that the medical team should keep track of.
