As humans in a complicated world we take many things home. Things like our problems, stuff we have to find the answers to because it was the end of the paid day at work, aches, pains and most of all arguments that spread like colds so we can continue them with someone else. It can be vengeful to consider that once a person is ill they eventually bring that problem to work by either staying out or through inflated insurance costs. That is, if your employer pays more when and if the company you work for exceeds insurance costs; so that if the insurance company pays a lot then your company has a huge increase as a result.
When looking for forms of treatment many people begin with home because it is cheaper, old fashioned and usually somebody else does all the work in attempts to cure an individual. If there are those that are considered "beams" on this planet of ours then it can be understood why people lose their balance and there are times when wishing for something can be difficult because people often remove those important factors in life that are crucial to the wish. In any instance I will resume with this weeks topic.
Neutron therapy involves a process whereby a beam of high dose neutrons is emitted by using a cyclotron to generate high energy neutrons. Once these neutrons are at a speed 50 MeV a probe attached to a gantry is used to transmit the beam into the patient for subsequent cure. Neutron therapy is considered more precise because the beam of neutron can focus primarily on the cancerous tumor or tissue rather than being radiated to other parts of the body. This is because protons are larger than electromagnetic waves or radiation so they can only go to a certain depth once released. Therefore enabling greater control as to how to direct the neutron beam towards the tumor so that it affects it enough to kill it entirely without destroying other parts of the body. An electromagnetic wave is designed to do the same with regards to radiation but since they have no mass or charge the electromagnetic waves can penetrate entirely through body tissue beyond the site of the tumor thus killing off good tissue and cells. Neutron therapy emits beams at a decided upon dose which in turn gradually releases the energy to rid the body of the tumor.
Neutron therapy can be best for cancer conditions that are difficult to operate on or inoperable cancers due to the size or location of the tumor. Of course there are some insurance companies that will not pay for such high tech procedures given the fact that neutrons were only discovered in 1932. Neutrons are considered high linear-energy-tranfer radiation, so they are able to combat cancer in size and in advanced stages. I'm not sure I understand what message insurance companies may want to send but, get well soon may not be much of a priority since Neutron therapy involves less treatment and time than the usual radiation therapy.
Tumors that are unable to be killed by radiation would mean that radiation is not effective in eliminating the cancer a person has. This results in loss of life to cancer unless another approach is used to prolong ones time against the disease. Since cancer is a deadly growth there is a possibility that even with radiation, cancer cells can repair and continue to regenerate. So there are times whereby the effort and procedure is outweighed by the personal risk factors of the individual and the ability to be able to tolerate radiation that also eliminates good body cells along with other procedures like chemotherapy to rid the cancer. Tumors that can be resistant include glandular, bone, cartilage, soft tissue and other large tumors.
Brachytherapy is known as internal radiotherapy. A radiation or radioisotope source such as Cobalt-60, Iodine-125, Caesium-137, Iridium-192 ect. is used. Again, these are radiotherapy radiations that are planted in a persons body either inside the tumor or near it's location in attempts to destroy it. Brachytherapy is given in low, med, high and pulsed doses(2 Gy-h to 12Gy-h) and can treat many forms of cancer. Since Neutrons emit higher doses of energy and can subject a tumor to be destroyed a lot faster or in less time there needs to be more use of neutron brachytherapy in dealing with cancers that are difficult to cure.
Surgeons use stents to open up clogged arteries in efforts to assist those who have either had heart attacks or to prevent persons with artery damage from having one. As with cancer there exists the spread of it, metastasis or secondary cancer that results from the same damage that the tumor has caused. In that if a person has heart disease one or more arteries may be blocked. If a person has cancer a tumor may exist thus causing another tumor or cancer cells to grown in other parts of the body. In elective measures to treat the entire body for cancer without major surgery in instances where there is a likelyhood that the cancer has spread Neutron Brachytherapy as a port and stent placement in the body could be considered by using,Californium-252 a neutron emitting radioisotope.
Procedure:
A stent(s) and port is created and placed into a tumor site or inside the tumor. One or more stents can be placed if one or more tumors exist. The stent is coated with Californium-252. The main stent, if more than one also acts as a port so that once a tumor has been destroyed but there is certainly presence of secondary cancer or metastasized growth to cells has resulted, the port will be used for furthur therapy. Neutron therapy can then be induced by using the neutron beam and directing the probe towards the port, in all efforts to release neutron directly to the cancer. Since the port acts as a guide and transfer mechanism for the neutron to be released into the body, this will enable tumors to have more of a direct contact with the high energy of the neutron in a minimally invasive way. This would be an attempt to eradicate inoperable tumors and to eliminate the cancer that has spread through the body because the neutron therapy as released through the port will eliminate any cancer that exists in the body.
The treatment amounts and times by which one may have to endure therapy may vary from person to person. But is is best to know that when illness spreads there is a state of the art solution to consider thus putting one in a decent state of mind. Unfortunately, sickness has many a passenger as it continues to go on- medicine needs to show them the way!
