If proton beam therapy is considered suitable by your cancer doctor, they will refer you to a specialist treatment centre where an assessment and planning session will be held before beginning treatment.<\/p>\n<p>Before your proton beam therapy, CT or MRI scans will be taken in order to help the team accurately target your tumor.<\/p>\n<h2>Benefits<\/h2>\n<p>Proton beam therapy offers more precise radiation, and thus reduced damage to healthy cells nearby. It is especially useful in the case of tumors near essential organs like the brain or bones; and cancers that have not responded well to other treatments like chemotherapy.<\/p>\n<p>Laser therapy may also be used to treat certain forms of eye cancer, such as ocular melanoma. Unfortunately, however, it&#8217;s only available at select NHS centres across the UK; you must travel for this treatment and speak to one of their specialist teams about whether it applies to your specific cancer.<\/p>\n<p>Research is still in progress to compare proton beam therapy and traditional radiotherapy for different cancers, but until that is completed, your doctor can advise which approach will be most suitable for you.<\/p>\n<p>Your proton beam therapy sessions will run daily from Monday to Friday and last 30-60 minutes each. Your radiographers will go over the process before commencing treatment; while it is best if you remain still while being administered the beam. Depending on where you&#8217;re receiving therapy, a mask or mould may also be required during delivery of treatment.<\/p>\n<p>Your doctor may suggest proton beam therapy alongside surgery and conventional radiotherapy, explaining its advantages and drawbacks.<\/p>\n<p>Your GP can refer you to a hospital offering proton beam therapy. Prior to beginning treatment, an assessment and meeting of team will need to take place at the proton centre; this may take several days and require 1 or 2 CT scans or an MRI.<\/p>\n<p>Proton beam therapy may be more costly than standard radiotherapy, but evidence is mounting that it delivers better outcomes for some cancers. Insurance companies tend to recognize proton therapy as medically necessary; thus more patients have begun accessing this option. As proton beam therapy is still relatively new technology, more research must be conducted into its long-term benefits and side effects relative to standard radiotherapy treatments.<\/p>\n<h2>Safety<\/h2>\n<p>Proton beam therapy differs from traditional radiation by targeting only specific areas with protons instead of surrounding healthy tissue and organs, sparing nearby healthy structures from unnecessary damage. Due to its precise nature, proton beam therapy is well-suited to treating tumors in complex regions like lungs or spinal cord where conventional radiotherapy might cause side effects.<\/p>\n<p>Recent research indicates that proton beam therapy could be as effective and safer than standard radiation for some cancers of the head, particularly for those diagnosed in its vicinity. However, the study has some important limitations that must be considered; such as an older population in proton group having more health issues than those in traditional radiation group which could skew results; nor did the research compare side effects between groups; instead just focused on how well each treatment worked individually.<\/p>\n<p>Proton beam therapy entails having the patient lie on a table while energy beams from a machine target their target areas. A team composed of radiation oncologists and radiation therapists use imaging tests like MRI or CT scans to locate target areas; then use computer models to plan how best to reach these with proton beams. When treatment sessions actually commence, cushions or body molds hold still so as not to interfere with protons being directed directly toward their intended locations by an attached device called a &#8220;gantry&#8221;, while directs beams directly at their target locations for maximum effect.<\/p>\n<p>Physicians can also pinpoint where their proton beam releases most of its cancer-fighting energy &#8211; known as Bragg peak &#8211; so as to maximize damage while limiting collateral effects to surrounding tissue.<\/p>\n<p>Proton beam therapy may be administered alone or combined with other treatments such as surgery, chemotherapy and standard radiation. As this form of therapy is relatively new and ongoing research needs to take place to understand its long-term benefits and risks; if you are considering this form of therapy it would be prudent to inquire further with your healthcare provider for more details.<\/p>\n<h2>Side effects<\/h2>\n<p>As its name implies, proton beam therapy directs cancer-fighting protons directly at tumor sites with incredible accuracy, enabling radiation oncologists to minimize or avoid side effects associated with traditional radiotherapy such as exposure of nearby healthy tissues and organs to radiation exposure.<\/p>\n<p>Beginning at an ion source, hydrogen atoms are separated into negatively charged electrons and positively charged protons. Once in the synchrotron, protons are rapidly accelerated up to 7 million electron volts within milliseconds for maximum penetration into body tissues and release of energy.<\/p>\n<p>Physicians can target where most of the protons in a proton beam release energy by adjusting a system known as Bragg peak. This allows physicians to target certain tumors or regions while sparing surrounding vital areas from harm. Once in treatment room, protons are sent through an accelerator called the gantry for delivery directly to patients.<\/p>\n<p>As they approach a tumor, protons slow down and interact with electrons in its target area to release cancer-fighting energy. A physician can then control this interaction to direct the proton beam directly onto its intended site of destruction with minimal collateral damage to surrounding tissues.<\/p>\n<p>Proton beam therapy allows for more precise targeting, which allows clinicians to reduce or even prevent late-onset side effects associated with radiation-induced complications that manifest months or years post treatment. Proton beam therapy often produces far fewer severe late side effects compared to traditional radiotherapy techniques.<\/p>\n<p>Proton beam therapy&#8217;s low toxicity may allow older patients with multiple medical conditions to participate in clinical trials that otherwise would exclude them due to frailty, which could increase cure rates, more effective treatments, and longer survival rates.<\/p>\n<p>Proton beam therapy is offered at select NHS hospitals in the UK for certain forms of cancer and only by specialists. Your team will assess if proton beam therapy is appropriate for you; if necessary, accommodation may also be made available nearby during treatment sessions.<\/p>\n<h2>Treatment<\/h2>\n<p>A special machine called a gantry directs a beam of protons towards an area needing treatment, stopping within cancer cells when they hit. This method kills cancerous cells while sparing nearby healthy ones from radiation damage. Protons offer higher radiation dosage without as much collateral damage to healthy tissue.<\/p>\n<p>Proton beam therapy may be used on its own or combined with chemotherapy and surgery treatments at RWJUH cancer centers, depending on your unique situation. Our doctors will consult with you on which approach is most suitable.<\/p>\n<p>As part of your treatment, several scans will be done of the area requiring treatment in order to gain a clear picture. Once these images have been reviewed by a clinical oncologist and physicist, they will use this data to plan your therapy session &#8211; they may mark certain parts of your body so radiographers know where you need positioning during sessions.<\/p>\n<p>Your therapist will then guide you into the treatment room and secure you with a device designed to keep you still during treatment sessions. Once on the table, your radiation oncologist will use proton particles to target your tumor; you may require multiple sessions depending on what kind of cancer is affecting you.<\/p>\n<p>Your treatment may leave you feeling tired at the start, as well as experiencing skin reactions like redness, dryness and itching &#8211; these side effects should resolve themselves within several weeks of finishing treatment.<\/p>\n<p>As more people live with cancer, it&#8217;s increasingly crucial that we provide new and improved treatments. Proton beam therapy offers hope of less tissue damage while potentially improving quality-of-life for many patients. Furthermore, proton therapy may reduce risk of recurrence (when cancer comes back after other therapies); more research needs to be conducted into whether this happens and, if it does so often.<\/p>\n<p> <iframe height=201 src=https:\/\/www.youtube.com\/embed\/o1RHSUUmUV0 frameBorder=0 width=360 allowfullscreen=true style='margin:0px auto; display: block;'><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>.
