Exploration of External Beam Radiation Therapy Treatment for Breast Cancer Patients - Free Essay Example

In 1896, Wilhem Conrad Roentgen (a German physics professor) presented a lecture introducing the x-ray. There was immediate worldwide excitement and systems were quickly developed to utilize this new technology and within three years x-rays were being used to treat cancer. The American Cancer Society (2014) describes that it was common for early radiologists use themselves to test the strength of the radiation coming from machines. They would use the skin on their arms to find a dosage that would produce a sunburn like reaction. This was called the â€Å"erythema dose† and was used as an estimate of the daily fraction to treat patients. This testing led to the discovery that radiation could cause cancer as many of these radiologists developed leukemia from the regular radiation exposure. Thankfully, methods and machines for delivering radiation therapy have continued to improve. Today there are many different techniques to delivery radiation therapy including external beam radiation, brachytherapy (internal radiation), and intraoperative radiation. The goal of radiation therapy is to treat the cancerous area while protecting healthy tissues and organs. This paper will explore the use of external beam radiation therapy for patients with breast cancer. In 2018 there will be an estimated 268,670 new cases of breast cancer – 266,120 for women and 2,550 for men (Siegel, Miller, Jemal, 2018). , Among women, this represents the largest number of new cases and the second leading cause of cancer death. According to the American Cancer Society (2017), external beam radiation is the most common type of radiation treatment for breast cancer. The American Cancer Society (2017) outlines common situations in which external beam radiation therapy is used: Following breast conserving surgery. Typically, the entire breast is treated (whole breast radiation) and a boost of radiation directed at the site where the cancer was removed. The boost is often given after the whole breast radiation treatment. Following a mastectomy with no lymph node involvement. Typically, the radiation is directed at the chest wall, mastectomy scar, and location of any drains exiting the body. If cancer was detected in lymph nodes, radiation treatment may be directed at these areas, commonly the axillary lymph nodes, supraclavicular lymph nodes, and internal mammary lymph nodes. Traditionally radiation treatment is performed five days a week for about five to six weeks. Accelerated breast irradiation is now being performed giving patients a larger dose over a shorter time. The American Cancer Society (2017) outlines these types: Hypofractionated radiation therapy – larger doses of radiation given in fewer treatments, usually for three weeks. For patients who had breast conserving surgery without cancer spread to axillary lymph nodes, results show that it is as effective in preventing cancer recurrence as treatment over five weeks and may also reduce short-term side effects. Intraoperative radiation therapy (IORT) – a single large dose of radiation is given in the operating room following cancer removal and prior to incision closure. 3D-conformal radiotherapy – computed tomography (CT) images are used to map the tumor bed and the radiation beams are directed to this area from multiple directions sparing healthy breast tissue. Treatment is given for five days, twice a day. Intensity-modulated radiation therapy (IMRT) is a newer treatment method. It is similar to conformal radiation therapy in that it uses CT images to map and direct the radiation beams from multiple directions to the treatment area. With IMRT, the strength of the radiation beams can be adjusted in each direction. Research suggests that IMRT may reduce toxicity in patients particularly in combination with partial breast irradiation in the prone position (Buwenge, et al., 2017). Cancer of the left breast introduces the challenge of treating the area while minimizing damage to the heart from radiation exposure.Various techniques aim to do this by considering the location of the treatment area and the patient’s anatomy. IMRT can reduce the amount of radiation in the beams that pass through the heart. Prone positioning allows gravity to pull the breast away from the heart during treatment. Deep inspiration breath hold (DIBH) moves much of the heart out of the treatment field. DIBH has been shown to reduce the mean heart dose in patients while also decreasing the dose to the lungs (Bergom, Currey, Desai, Tai, Strauss, 2018). Another modern technique is volumetric modulated arc therapy (VMAT) and is an evolution of IMRT. With IMRT, the radiation beam is directed at a fixed number of locations with each beam having its own intensity level. VMAT allows for radiation to be delivered along the entire rotation of the machine arm and for the intensity to be adj usted at each position. It seems that the research of VMAT in treating breast cancer is limited and it is unclear when this technique would result in an advantage over established methods (Cozzi, et al., 2017). Radiation therapy to treat breast cancer as well as radiation therapy in general is an ever-evolving field. Research continues to fine-tune current strategies and develop new ones.

Symptoms And Symptoms Of Depression And Bipolar II Disorder

Now I can see that these were signs I was starting my first depressive episode. I was eighteen and a bit ahead of the curve in terms of onset for both depression and bipolar II disorder. However, I always did like to be early for things so I guess shouldn’t be surprised. Apparently, early onset of symptoms means a poorer prognosis for treatment, but I try to ignore that fun little tidbit of information. Another fun fact, people born in the winter are apparently more likely to develop either bipolar I or bipolar II. A link had also been found between the seasons and what times of the year depression episodes occur for individuals with a bipolar disorder. No one seems to know why. That seemed to be something that comes up again and again, even with all the research, that no one really knows why the brain works the way it does with most mental illnesses. Even when they have tangible, visible differences in brain structures they aren’t sure what’s going on. One artic le I read found that the prefrontal cortex size was larger in individuals with bipolar disorder who had a suicide history without psychiatric hospitalization, but smaller in individuals with a suicide attempt history who had past hospitalizations. The authors went on to explain why this might be, more severe cases or the type of treatment, but they weren’t sure if that was actually the case.

John Donne s A Fever - 1270 Words

A Fever: Theodore M DeConne Southern Connecticut State University â€Å"Love,† is described as a feeling of warm personal attachment or deep affection, as for a parent child, or friend (â€Å"Love†). As a metaphysical poet, John Donne is known for use of strange paradoxical imagery, complicated thought, and questioning the nature of the reader’s reality. In the sonnet, â€Å"A Fever,† Donne explores an unusual and complex love that he has for a woman. Throughout this poem Donne makes use of the contrasting themes of love and hate. While some might this consider this unusually, Donne’s use of the contrasting themes of love and hate show that the love a woman can give purpose to a man’s existence. Donne begins his poem by asking the woman he loves not to die. He goes on to say â€Å"Do not die, for I shall hate, all women so, when thou art gone.† This is Donne’s first use of the contrasting themes love and hate. Donne loves this woman so much. He shows this claiming that if she survives her illness he will love her, however if she dies he will hate all other women. His life will have no meaning without her, and he cannot possibly love another woman, so he has no choice but to hate all women. â€Å"That thee I shall not celebrate, when I remember, thou wast one(John Donne: A Fever).†, and he cannot celebrate her death, because the reminder of her death will be too painful and he will also be reminded that she was also a woman.

Characteristics of Metaphysical Poetry free essay sample

What is a metaphysical poem? Metaphysical poetry is concerned with the whole experience of man, but the intelligence, learning and seriousness of the poets means that the poetry is about the profound areas of experience especially about love, romantic and sensual; about mans relationship with God the eternal perspective, and, to a less extent, about pleasure, learning and art. Metaphysical poems are lyric poems. They are brief but intense meditations, characterized by striking use of wit, irony and wordplay.Beneath the formal structure (of rhyme, metre and stanza) is the underlying (and often hardly less formal) structure of the poems argument. Note that there may be two (or more) kinds of argument in a poem. In To His Coy Mistress the explicit argument (Marvells request that the coy lady yield to his passion) is a stalking horse for the more serious argument about the transitoriness of pleasure. The outward levity conceals (barely) a deep seriousness of intent. You would be able to show how this theme of carpe diem (â€Å"seize the day†) is made clear in the third section of the poem. Characteristics of Metaphysical Poetry ?Startling comparisons or contrasts of a metaphysical (spiritual, transcendant, abstract) quality to a concrete (physical, tangible, sensible) object. In A Valediction: Forbidding Mourning, Donne compares the love he shares with his wife to a compass. ?Mockery of sentimental romantic poetry ?Gross exaggeration (hyperbole) ?Presentation of a logical argument.Donne argues that he and his wife will remain together spiritually even though they are apart physically. Metaphysical Poetry The Flea + Sune Rising Metaphysical poets use startling juxtapositions in their poetry to create a greater significance in their arguments and intended meanings throughout the poem. John Donne is said to be the unsurpassed metaphysical poet, metaphysical poetry being poetry relating to a group of 17-century English poets whose verse is typified by an intellectually arduous style, admitting xtended metaphors and comparing very disparate things. In 17th century England new discoveries were being made and social customs such as men being the dominant over women still applied. Through Donnes poetry we can see that he is goaded and confused by the new discoveries and the social customs avert him from reaching his desires. This is incalculably recognized in his two poems, The Sunne Rising and The Flea where Donnes arguments challenge some beliefs of the 17th century England.Through The Sunne Rising we gain a sense of meaning that Donne is irritated and perplexed with new discoveries and that he believes his loveis everything in the whole world. In The Flea we can see Donne challenging the social costumes of the 17th century, such as chastity of women, his tremendous persistence to sexually unite with the woman and the overall dominance presented over the woman. In both of these poems Donne uses vividly striking differences in the argument to emphasize the overall meaning of the poem.These dramatic contrasts include conceit, binary opposition, imagery, specific words and the movement of the poem, which are additionally affirmed by poetic devices. The Sunne Rising implies that when a couple unearths perfect love together they become one, shaping a world of their own, which has no need for the outside world. He suggests that even the physical laws of the universe must defer to those persons caught up in the larger universe of infatuation. We also see Donne is going through a struggle of the old and new during the poem.In the Sunne Rising Donne uses a number of dramatic.. . Metaphysical Poetry Metaphysical poetry, a term coined by Samuel Johnson, has its roots in 17th-century England. This type of poetry is witty, ingenious, and highly philosophical. It topics included love, life and existence. It used literary elements of similes, metaphors, imagery, paradoxes, conceit, and far-fetched views of reality. John Donne is regarded as the â€Å"leading poet† of this highly intellectual form of poetry.Donne was influenced by the belief that the precision of beauty in the adored (loved one) behaved as a commemoration of ideal beauty in the everlasting kingdom (heaven). He also used unconventional and colloquial rhythm and tone, which was highly contrary to the Elizabethan poetry style. Metaphysical poets : The name given to a diverse group of 17th? century English poets whose work is notable for its ingenious use of intellectual and theological concepts in surprising conceits, strange paradoxes, and far? fetched imagery.The leading metaphysical poet was John Donne, whosecolloquial, argumentative abruptness of rhythm and tone distinguishes his style from the conventions of Elizabethan love? lyrics. Other poets to whom the label is applied include Andrew Marvell, Abraham Cowley, John Cleveland, and the predominantly religious poets George Herbert, Henry Vaughan, and Richard Crashaw. In the 20th century, T. S. Eliot and others revived their reputation, stressing their quality of wit, in the sense of intellectual strenuousness and flexibility rather than smart humour. The term metaphysical poetry usually refers to the works of these poets, but it can sometimes denote any poetry that discusses metaphysics, that is, the philosophy of knowledge and existence. John Donne, is remembered today as the leading exponent of a style of verse known as metaphysical poetry†. Metaphysical poetry typically employs unusual verse forms, complex figures of speech applied to elaborate and surprising metaphorical conceits, and learned themes discussed according to eccentric and
