If cure is not possible, chemotherapy may be given to minimize the discomfort caused by cancer or slow the progression of the disease to prolong the patient's life (palliative treatment). Types of Chemotherapy Drugs Just like scalpels, lasers, and electric currents are used in surgery, the weapons used to fight cancer in chemotherapy are a host of anti-cancer drugs. How differently these drugs kill cancer cells, or prevent them from dividing, depends on their classification. Drugs in the same class kill cancer cells by the same mechanism: they all attack the same target within the cell. Depending on the type of cancer and the kind of drug used, chemotherapy drugs may be administered differently.
According to Gerber (2008, p.312) the drugs involved in targeted therapy works initially by preventing the growth of cancerous cells. Targeted therapy interrupts the specific molecules which are required for growth and development of a tumor. It blocks the proliferation of cancer cells. Gerber’s (2008, p.311) studies show that the targeted therapy drugs are used to treat many malignancies including breast, colorectal, lung and pancreatic cancers as well as lymphoma, leukemia and multiple myelomas. The main two types of targeted therapy include monoclonal antibodies and small molecule inhibitors.
A high generation of free radicals and weakening of the antioxidant defense system contributes to a state of oxidative stress in the brain, which can affect memory, cognition, ability to concentrate and to learn and remember things. In this regard, astaxanthin is an interesting compound because it protects the brain health by counteracting the negative effects of oxidative stress. It acts as a protective shield and protects the brain cells against damage and death caused by free radical attack. Astaxanthin protects the neuronal integrity by suppressing the production of pro-inflammatory compounds in the brains of older individuals. It further promotes neurogenesis, a process in which, nerve cells are generated in the brain, which enhances memory and improves overall quality of life.
Is it something that can help save people or is it a threat in which there are more consequences to come? With this intention, people should think twice about putting their lives into vaccinations. Considering the question being asked in the beginning, what exactly is a vaccination? According to MedicineNet, vaccination is an “injection of a killed microbe in order to stimulate the immune system against the microbe, thereby preventing disease. Vaccinations, or immunizations, work by stimulating the immune system, the natural disease-fighting system of the body.” Although this world-renown definition sounds convincing, the definition itself contradicts the importance of the immune system; “natural disease-fighting system.” Rather, the function of vaccinations disrupts the purpose of what the immune system can do to the human body.
We are less susceptible to what used to be common illnesses. We have also extended our knowledge of the human body and mind. Without human experimentation many of the diseases that were previously eradicated would still be prevalent, and plaguing mankind. As stated earlier, our lives would have been much different if human experimentation hadn 't taken place. If people like Edward Jenner, who invented the smallpox vaccination had thought that human experimentation was unethical, our population as of current would be much less, possibly even eliminated.
To cure a solid tumor, local control of the primary malignancy must be achieved. Chemoradiation therapy, also known as chemoradiotherapy is a cancer treatment that combines chemotherapy with radiation therapy. The use of chemoradiation therapy can reduce and even terminate the need for surgery. Local, regional, and distant diseases relative to surgery can be reduced greatly. It also reduces sickness, while undergoing treatment and the risk of relapsing once in remission.
According to the author Arthur Caplan one of the possible benefits of genetic engineering is eliminating genes known to cause cancers and hereditary diseases, “This would allow us to eliminate heartily diseases (sickle anemia, type one diabetes, and so) allowing our children to live a better life” (Caplan). By being able to cut out a certain genes that are connected to cancers and hereditary would lead to lesser amount of people dying and suffering from something that they have no say over. The author Gordon Dillow argues that a possible discoveries would lead to more of a perfect population, “The results of such discoveries could benefit humans immensely, possibly eradicating genetic defects” (Dillow). With many benefits of Genetic Engineering there are still those who oppose to it. But on the other hand, Genetic Engineering can possibly lead “Playing God” to being able to create Humans “designer babies” inevitably going against morals of various societies.
After the surgery is completed the bone is not immediately replaced, or in some cases the bone is not replaced at all. The main reason for this is so possible post operative swelling doesn’t cause further pressure. The next step is usually radiation therapy, which is used to treat many types of cancers because the radiation damages the cancer cell 's’ DNA to the point where it effectively kills the cell. Radiation may be conducted alone or in combination with other treatment methods such as chemotherapy. Radiation therapy may also be the first option if surgery is not possible.
2. Use of Lasers To Treatment Keloids The treatment of keloids use this laser is more effective to flatten keloids and reduce the rash occurs when undergoing cortisone injections to remove keloids. This treatment is safe and will not be too painful, just take a couple of sessions to achieve maximum results, but is also a factor the cost of this treatment is very expensive. 3. Remove Keloids With Surgery The treatment of keloids this one can be classified as acts that are in danger, to cut the keloid will be able to ignite a new keloid as a result of cuts when cutting keloids.
There is no cure for PKD aside from a kidney transplant, but a patient’s symptoms can be treated in order to eliminate some of the pain and discomfort. A patient’s high blood pressure can be treated through medication and lifestyle changes such as decreasing the amount of sodium in their diet and increasing the amount of exercise they get. Patients can take acetaminophen to reduce pain, but in severe cases, physicians may surgically remove the cysts in order to reduce the pressure and pain they are causing. Other treatments include prompt treatment of any infections, increased fluid intake to dilute urine in cases where patients notice blood in their urine and dialysis (Mayo Clinic Staff,
In the US, cancer is the second major cause of death. Cancer is the uncontrolled division of somatic cells caused by defective cancer cells. Usually, when cells divide, they begin to form a layer. Normal cells will experience contact inhibition, where cells can cease to replicate once there is no more space for it to inhabit. However, cancer cells cannot control their division.
Cell-mediated immunity also works to attack the "foreign body" but is uses T cells that are directly attached to the transplant. This eliminates the infected cell" before it has time to multiply. (Alberts, B. 1970) 2. Your immune system is constantly working to fight off foreign invaders.
Intravenous gamma globulin interacts with the cells to quiet down the immune response. When inflammation occurs in the vessel wall it causes the artery to dilate, if treatment is given within 10 days the artery can return to normal size without scarring. However if the inflammation is treated late or the Intravenous gamma globulin is not effective, permanent damage can occur to the arterial wall, sometimes this results in an aneurysm. When it balloons it causes the blood to swirl and increase the risk of blood clot formation. If the blood clot continues to grow this can result in blocking of the vessel and a heart attack can occur.
However, when our bodies encounter unfamiliar antigens our immune system may not be able to fight off the antigen before infection occurs resulting in us becoming sick. This is where vaccines can be beneficial. They work by preparing the immune system for possible exposure to a virus by injecting a weakened or dead form of the virus into the bloodstream. Hence, infection does not occur as immunity is achieved and the immune system knows how to combat the foreign invader when exposed to a stronger form of the virus. As a result of vaccination, antibodies will be produced that attack the weakened virus without infection occurring as it would with natural infection.
The internal health problems ruin the immune system, making it harder to fight skin cancer and other diseases. Th tanning alternatives are very important as of right now because as I state again the long term effects are not known, but now they are. So instead of tanning, think
