One of the scariest aspects of lung cancer is the fact that you don’t know you have it until it may be too late. Luckily, due to advances in modern medical technology, we are now able to detect lung cancer within the body before it has spread. CT screening, according to a 13-year study conducted by the New England Journal of Medicine, was able to reveal early-stage lung cancer in 85 percent of patients.
Seeing as about 1.4 million people in the world are killed by lung cancer each year, and half of all those diagnosed with lung cancer die within the first year after diagnosis, the importance of undergoing screening cannot be understated. Some people are more at risk than others, so it is critical to your well-being to know whether you are a high risk patient, moderate risk patient or low risk patient.
The NCCN defines a high risk patient as someone who is age 55 or older and has accumulated 30 or more pack years of smoking (unless they quit smoking over 15 years ago). At American Diagnostics Medical, we specialize in screening and treatment of high-risk patients, so don’t hesitate to schedule an appointment if you fall into the high risk category. Regular breast self exams and routine mammograms are two of the most important steps we can take for good breast health. Women generally do not need to have their first mammogram until age 40 unless breast cancer runs in the family. We will discuss the different types of mammograms as well as x-rays and Magnetic Resonance Imaging (MRI). Women age 40 and older should have a screening mammogram every year and continue to do so for as long as they are in good health.
A mammogram is a special type of low-dose x-ray designed to specifically screen breasts for cysts, cancerous and non-cancerous lesions and lumps.
Strict guidelines ensure that mammogram equipment uses the lowest dose of radiation possible to make high-resolution (very detailed) images of your breast tissues. If you have breast implants, you will need several different views per breast instead of the average 2 views per breast. For a mammogram, the breast is compressed between 2 plates to flatten and spread the tissue to produce a good, "readable" mammogram. Normally, the clinic or your doctor will contact you within two weeks with the results of your mammogram. The best time to perform a breast self exam (if you are still menstruating) is about 3 days after the last day of your period. If you are post-menopausal, you should pick a time of the month that is most convenient to you and stick with it, examining your breasts the same day each month to compare variances from exam to exam.
Stand in front of a mirror with your hands pressing firmly down on your hips, which contracts the chest wall muscles and makes any breast changes more obvious. Next, lie down on a firm bed or floor, completely flat, so your breast tissue, glands and fat cells spread out to the sides more easily.
Move around the breast in an up and down pattern starting at an imaginary line drawn straight down your side from the underarm and moving across the breast to the middle of the chest bone (sternum or breastbone). Take note of any discharge, changes in contour, color, lumps, firmness, pressure sensitivity or anything else you find odd and report them to your physician immediately. Your breast self exam may take a few minutes the first time you do it, but you will gain confidence and speed as you get accustomed to it.
For some women who are at high risk for breast cancer, a screening MRI is recommended along with a yearly mammogram. If you are 35 and over, you should be instructed by your surgeon preoperatively to obtain a mammogram and report before any breast procedure is performed. Researchers say clots in abdominal veins could alert doctors to cancer that hasna€™t been diagnosed yet.

La preocupacion por los efectos secundarios del tratamiento es el principal motivo de oposicion entre el grupo de pacientes mayores de 75 anos. Los pacientes mayores con cancer de colon tienen menor predisposicion a recibir quimioterapia complementaria, segun un estudio de la Escuela de Medicina de Harvard en Boston y la institucion de investigacion RAND Corporation que se publica en la revista Journal of the American Medical Association (JAMA). A pesar de la menor predisposicion de estos pacientes a recibir quimioterapia despues de la cirugia debido a la preocupacion por los efectos secundarios, la investigacion indica que cuando reciben este tratamiento resulta menos toxico y de menor duracion que la terapia que reciben pacientes mas jovenes, y ademas, los pacientes mas mayores experimentan menos efectos secundarios.
Los pacientes fueron seguidos durante 15 meses tras el diagnostico y pertenecian a cinco regiones (Alabama, Iowa, Los Angeles, California y California del Norte), cinco sistemas de salud integrados y 15 hospitales de veteranos de guerra. Los investigadores descubrieron que de forma global, 513 de 675 pacientes con cancer de colon en fase III (el 75%) no recibieron quimioterapia complementaria. Los pacientes de 65 anos o mas eran mas propensos que los jovenes a dejar la quimioterapia en todo momento del tratamiento. En lo referente a estos efectos adversos, el 24% de los pacientes presentaba al menos uno y estos se producian dos veces mas frecuentemente en muchos pacientes que recibian la quimioterapia frente a aquellos que no. The thought that something deadly is growing inside of you, but you can’t feel any symptoms or ill effects, is frightening to think about. This is a concept known as early detection and is performed through the use of various detection tools. This early detection via CT screening resulted in an 88 percent 10-year survival rate among the 484 subjects diagnosed with cancer. The National Comprehensive Cancer Network notes that patients who fit the criteria of the latter category do not need to be screened. You may also be labeled a high risk patient if you are age 50 years or older, have smoked for 20 or more years and meet any of the following factors: contact with radon, asbestos or other cancer-causing agents, having had other certain types of cancer, family history of cancer and lung disease. Thanks to our ultra-low dose radiation, which we wrote about in our last blog, screening has never been easier or safer. You don't have to like them, but you should do both before having your surgery, especially if you are 35 or over, have a history of breast cancer in your family, or if you just want to know that your breasts are clear of any problem.
However, a mammogram is often recommended before breast reduction surgery for women who are 35 and over, followed by a post-op procedure at the 3 to 6 month mark to be used as a baseline for future mammograms.
I will also show you some photos you don't want to see and some that you should see, and I've included a diagram to help you visualize the correct way to perform a monthly breast self exam. The goal of screening exams like mammograms is to find cancers before they start to cause symptoms. Breast x-rays have been around since the 1920's, but modern mammography has only existed since 1969.
Many women report that they feel awkward, uncomfortable and perhaps a little violated during the mammogram, but you should experience no real pain. The technician must immobilize your breast to get a proper view and to reduce any blurring. The breasts normally swell and can develop typical lumpiness when you are ovulating (about 14 days after your period ends) and again when you're premenstrual. Look for anything out of the ordinary on your breasts — changes in size or color, contour or dimpling, or redness of scaliness of the nipple or breast skin.
MRI uses magnets and radio waves instead of x-rays to produce very detailed, cross-sectional images of the body. It is helpful to keep a journal of your findings to discuss with your physician should any abnormalities surface.

Kahn de la RAND Corporation en Santa Monica, Estados Unidos, analizaron el uso de quimioterapia adyuvante y episodios adversos segun la edad en registros y encuestas medicas en un grupo multiregional de 675 pacientes diagnosticados con cancer de colon en fase III entre 2003 y 2005, que pasaron por la extirpacion de parte del colon.
De los 202 pacientes de 75 anos y mayores, el 50% recibio quimioterapia suplementaria en comparacion con el 87% de los pacientes mas jovenes.
Entre quienes recibian quimioterapia adyuvante, las tasas de efectos secundarios eran menores para los pacientes de 75 anos y mayores frente a los pacientes mas jovenes. El numero medio de episodios adversos unicos era tambien mas alto entre quienes pasaban por la quimioterapia.Los autores senalan que los metodos para ayudar a los especialistas sobre la seguridad de la quimioterapia para pacientes mas mayores con otros trastornos podria aumentar la probabilidad de que se descubrieran beneficios evidentes de la quimioterapia en los estudios.
However, just because you are a moderate risk patient at one point in your life, doesn’t mean that you can’t jump to a high risk patient later on. According to the American Cancer Society, despite advanced technology and increased awareness, breast cancer remains the #2 cause of cancer-related deaths in women. Breast cancers found during a self exam tend to be larger and are more likely to have already spread beyond the breast, according to ACS, while those found during screening exams are more likely to be small and still confined to the breast. By comparison, a woman with breast cancer who undergoes radiation treatment will receive around 5,000 rads. Be sure that your chosen clinic is accredited by the American College of Radiology (ACR) to assure the highest quality of mammography equipment and technicians. However, if you should have sharp pains or intolerable discomfort, tell the technician right away so that she can reposition you. The entire appointment should take no more than a half-hour if you have implants, or 15 to 20 minutes for un-augmented patients.
It means they will remove a cyst, lump, or lesion from your breast, which means more waiting on your part.
Raise each arm separately and slightly to check for any changes between when your arm is at your side and when it's raised. To begin, raise either arm over your head and use the pads of your three middle fingers of the opposite hand to feel for lumps in the breast. It requires special equipment, and higher quality images are produced by dedicated breast MRI equipment than by machines designed for MRI scanning of other parts of the body, including the head, chest or abdomen. Estos analisis podrian convertirse en herramientas de apoyo para que los especialistas predijeran la eficacia de la quimioterapia, incluso en pacientes con edad avanzada y otras enfermedades.
Regular mammograms put your mind at ease and alert you to possible tumors, cysts and calcifications that may need to be biopsied.
The size of a breast cancer and how far it has spread are important factors in predicting the prognosis of a woman with this disease. The ACS notes that if a woman has yearly mammograms beginning at age 40 and continuing until she's 90, she will receive between 20 and 40 rads total. Some women report the cessation of caffeine intake helps decrease discomfort significantly. Use overlapping dime-sized circular motions and 3 different levels of pressure to examine your breast: light pressure to feel the tissue closest to the skin, medium pressure to feel a little deeper and firm pressure to feel the tissue closest to the chest and ribs. You may find it helpful to keep a journal for your breast self exams so you can make comparisons from month to month and as a reference should the need ever arise for you to discuss any abnormalities with your physician.
